ADAM SCHULTZ, OF CINCINNATI, OHIO.
BEER-KEG WASHER.
.l-PECILFIUATION forming part of Letters Patent No. 318,306, dated May 19, 1885.
Application filed March'l, 1854. (No model.)
To @ZZ whom it may concern:
Be it known that I, ADAM SoHUL'rz, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new anduseful Improvements in Beer-Keg Washers, of which the following is a specification.
My invention .relates to apparatus or mas chinery for scrubbing or washing the external surfaces of beer-kegs, barrels, and similar articles, and has for its object the construction of an apparatus in which the entire operation of charging the Same with kegs, scrubbing the kegs, and finally discharging the cleaned kegs from said apparatus shall be accomplished mechanically, without manual labor, and with the smallest possible. consumption of water. The apparatus is also designed to clean the kegs much more rapidly than by any other method of scrubbing with which I am acquainted.
In the accompanying drawings, Figure 1 is a longitudinal sectional elevation of my improved scrubbing-machine. Fig. 2 is a plan thereof; Fig. 3, elevation of gearing on the driving side of the machine. Figs. lland 5 are detached views of the devices for feeding the kegs to themachine. Fig. 6 is a detached view of the endless keg-conveyer chain and sprocket-wheel; Fig. 7, elevation of gearing on the driven side of the machine. Figs. S, 9, and 10 are detached views of devices for shifting the vertical or end brushes to receive and discharge the kegs. Fig. 11 is a section through horizontal or side brush, and Fig. 12 is a de. tachedviewof the spring-beari ng foi-sprocketwheel and endless chain.
Similar letters of reference indicate similar parts.
A is a large tank, made water-tight at the `joints, of wood or metal, into which water is introduced to the level indicated by dotted lines x .r of Fig. l.
B is ashaft, j ournaled at I) in a bearing formed in or attached tothe side of tank A, and in bearings b b placed outside of tank.
B is a hollow or tubular shaft, mounted upon shaft B, and provided with the pulley Bto which motion is transmitted from asteamengine or other prilne mover by belt in the customary manner.
Biis aspur-pinion, and B* a spur-gear,trans mittin g motion from shaft B to shaft B5, mounted in bearings b2 BG is a spur-pinion, and BT a spur-gear, transmitting motion from shaft B5 to shaft B. The rela-tion of pinions B3 B6 to spur-gears B4 and B7 is such that shaft B5 revolves at one-half the speed of shaft Band shaft B revolves at one-half the speed of shalt B5 and one-fourth the speed of shaft B. These proportional speeds are not absolute, but are what I prefer to employ.
To the inner end of hollow shaft B', I attach by keying, 0r in any approved manner, the spur-gear C, (shown in dotted lines, Fig. 1, and in elevation in Fig. 3,) which gear communicates a rapid motion to pinions D D', which pinions, respectively, drive the horizontal or side brushes, d, and vertical or end brushes, d. The brushes cl are mounted upon shafts d2, journaled at their ends in the housings E lfl, which housings are securely keyed or otherwise mounted upon and caused to re- Volve with shaft B, while the brushes d are mounted upon short shafts di", journaled in the housings E E.
Upon the side of the machine next to hol low shaft B the pinions D D', and consequently the brushes d d,are driven from spurgear C, Fig. 3; but upon the side of machine lopposite hollow shaft B (see Fig. 7) the pinion D:s and brushes d are driven by the spur gears or pinions D on through shafts dt. The proportions of pinions D2 D are such that the rate of motion imparted to the vertical brushes d upon the side of machine next to housing la" is the same as upon the side of machine next to housing E and spur-wheel C; but the motion of vertical brushes d upon opposite sides of the machine willv bein opposite directions.
The housings E E being securely keyed to shaft B, itfollows that as shaft B revolves at one-fourth the speed of shaft B, and consequently of spur-gear C, the housings and brushes (l d will have a motion around the axis of shaft B in the direction of arrows, Fig. 1, ata comparatively slow rate, while the brushes (l d are revolved about their axes in the direction of the arrows, Fig. 1, at a comparatively rapid rate to cleanse the keg.
The spurwheel (l is shown as possessing fifty teeth, while the pinions D have. thirty teeth, and the pinion D twenty teeth, and said spur-wheel C makes four revolutions to one revolution of shaft B, whence the brushes d d will revolve at eight times the speed of housings E E', or one complete circuit of housings E E produces eight revolutions of the brushes d d. Assuming the normal speed of the machine to be twelve revolutions per ininnte, equivalent to the delivery of forty-eight kegs, then the scrubbing-brushes d d will revolve at a speed of ninety to one hundred revolutions per minute.
F F are sprocket wheels, mounted upon shafts f f', which latter are journaled in suitable bearings in the sides of tank A, around which sprocket-wheels and ant-i-friction rollers f2 is trained the endless chain G. The antifriction-rollers are mounted on shafts f, and turn in suitable bearings in sides oftank A.
Referring to Fig. 1, the side of chain G next to shaft B has a motion coincident with housings E FJ, as indicated by the arrows.
VH is an inclined railway, upon which the kegs are laid and down which they roll by gravity to the chute or opening H,where the Vswinging spring-lever 7L in conjunction with the abutment h retains each keg until it is au tomatically fed into the machine. The swinging spring-lever consists of the lever 71, shaft 71.*, and two arms, It lz, pendent from shaft r. The latter carry at their extremities the detents hwhich engage with the external surface of the keg below the horizontal center there of, as showniu Fig. 1. rlhe abutment 71.', secured rigidly to tank A, and the detent h2 on swinging spring-lever l1, are faced with rubber to increase the frictional contact of the surfaces with external surface of keg. The lever 71y is pivoted in suitable bearings under the in ner end of railway H, and is pressed toward the keg by the spring h". The lower end of lever h whenin position (shown by full lines of Figs. 1 and 5) engages with the projecting end of shafts di, (upon which the horizontal brushes are monnted,) and as the housing E revolves forward t-he lever h is pressed away from the keg, as shown by dotted lilies, Fig. 5, until the detent ht and abutment h release it, when it drops in between two vertical or end brushes, rl, and two horizontal or side brushes, d, where it is retained by the endless chain G until it is scrubbed, and finally discharged from the machine. Directly the keg is released from abutment 71, and dctent It' the swinging lever h isvforeed back to its normal position by spring 71?", to intercept and retain the next succeeding keg in chute H.
The normal position of the vertical brushes fl is such that t-he bristles are pressed with sufficient force against the ends of the keg to readily scrubv away any dirt on the heads thereof, but in order to admit or receive the dirty keg from chute H between the end brushes, (Z, which assist in the discharge of the scrubbed keg at the end of its circuit from the machine, the end brushes or one of each pair (of which four pair are shown in the drawings) must have a longitudinal motion upon their shafts d" sufficient to clear the chine of the keg. rllhis I accomplish by the devices shown in Figs. 8, 9, and 10, of which d* is an annular groove cut in the hub of brush d', into which is fitted the shipper-bar I. lis a fulcruni,attached to and revolving with the housing E, in which the shipper-bar 1 is pivoted.
l is a spindle, pivoted to the extreme end of shipper bar I, and playing longitudinally through a guide, c, in housing E, as shown in Fig. S.
J J are concentrica-lly disposed inclined planes, rigidly attached to sides of tank A, one, J, above, and the other, J, below, the plane of shaft B, with which the outer ends of spindle l intermittingly engage, as the shaft B and housings E E make their revolution.
The spindle l', engaging with inclined plane J or J, as the case may be, the spindle and outer end of shipper-bar I are pressed inward, as shown by dotted lines of Fig. 8, while theinner end of shi pper-bar and vertical brush d are pressed outward, as shown by dotted lines, same figure, sufficiently to either receive the keg from chute H or discharge the keg after being scrubbed, as the spindle 1 engages withinclined planes J or J', respectively. Directly thespindle I,by the revolution of housing F1, has passed the inclined plane J or J', the brush d is forced back by spring t" to its normal po sition on shaft d, as shown in full lines of Fig. S. The hub of brush d is splined, and is driven by a feather set in the shaft cl3. Each of the vertical brushes d. upon the driving side of the machine is -provided with the devices just described for producing the longitudinal motion of brushes rl; but only two inclined planes are required, one to operate the devices to receive the keg, and the other to operate the devices to discharge the keg.
The horizontal brushes d are provided with rings d5, (see Fig. 11,) which loosely fit the core or wooden center of the brush and roll around the saine b v frictional contact with the keg. The rings (l5 limit the pressure of the keg on thebristles of the horizontal brushes d. The endless chain G is driven from sprocket wheel F, and this in turn driven from tubular shaft B by spur-wheels Fl Fi".
The endless chain G is geared to travel at such a speed as will roll the keg through one complete revolution upon its own axis between the points where it is received and discharged by the scrubbing mechanism.
K is a lifter, consisting of the four hooked arms L 7.', mounted upon shaft K, which latteris liournaled in suitable bearings in the sides of tank A, and also in bearing It" outside of the tank.
Upon the outer end of shaft K is keyed a sprocket-wheel, L, and upon shaft B, Fig. 2, is keyed a sprocket-wheel, L, transmitting motion by endless chain LL to shaft K', and consequently to the hooked arms k 7o of lifter l. The sprocket-wheel L is twice the diameter of sprocket-wheel L, to canse the shafts B and K to revolve at the same angular speedthat is, cach revolut-ion of shaft B and hous- IOO ings E E is accompanied by a corresponding revolution of lifter K.
The housings E E' and brushes d d', with their respective mountings, in conjunction with the endless chain G, to roll the keg. I term the scrubber or washerf7 and the hooked arms 7l: 7s and shaft K' and its drivinggear, I term the liften the latter being designed to receive the cleaned kegs from the scrubber and deliver them successively, as shown in Fig. 1, to the inclined railway M, from whence they roll away by gravity to the charging-cellar.
By reference to Figs. 1 and 12 itwill be observed that the shaft of sprocketwheel 1?' is mounted in elastic bearings, one on each end of shaft f', which, by the pressure of spring ft against the movable bearingf, mounted in guides f t, keeps thedescending side of chain I taut, and holds the kegs firmly against the rings d on horizontal brushes d until delivcred to the lifter K.
The operation of the machine is as follows: Water being supplied to the lineI x fr in tank A, and power transmitted to pulley B2 to give motion to the scrubber, the kegs are placed upon inclined railway H, as illustrated by the dotted circles of Fig. 1, and roll down into the chute H', where they are retained by devices h h' lr h, Figs. 4 and 5, until delivered to the scrubber by the contact of projecting end of shaft d2 with springlevcr 71., (the vertical brush d upon the driving side of the machine having been shifted by the devices shown in Figs. 8, 9, and 10 to receive the keg.) rIhe k eg is received between two vertical brushes d' and two horizontal brushes d resting on rings di and passed around the scrubber, as shown in Fig. l, during which process the brushes d d' are revolved against the side and ends ofnkeg in the water ot' tank A. Directly the keg has passed beyond the supporting infiuence of endless chain G it is caught by the hooked arms of lifter K and delivered to the inclined railway M.
The water in the tank is renewed as required, and the tank may be supplied with inlet and outlet pipes and valves for convenience in managing the water-supply; but in every instance the water of tank Ais used until its condition is unsuited to the cleansing of kegs, when the foul water is discharged and a new tankful supplied. In this manner no water is wasted as in the processes now in general use by breweries, where the water is proj ected by hose or nozzles under pressure against the kegs to wash off the dirt. These are details not material to my invention, and are not show in the drawings.
I do not wish to confine myself to the arrangement of drivinggear shown, because this may be varied to suit different applications ofthe machine without departing from the principles of my invention.
Having described my invention, what I claim is- 1. In a machine for scrubbing kegs, thel combination of a series of horizontal revolving brushes and a series of revolving vertical brushes, with devices, substantially as shown, for delivering the kegs to the revolving scrubhing-brushes and removing the cleaned keg from said brushes, and a watertight tank, A, substantially as described.
2. In a machine for scrubbing kegs, the colnbination of the series of horizontal revolving brushes d, the series of revolving vertical brushes d', and the housings E E',with devices, substantially as shown, for the delivery of the keg to the brushes and removing the cleaned keg from the brushes, substantially as dcscribed.
3. In a machine for scrubbing kegs, the combination of a feed mechanism consisting of the swinging lever h, detents 71.2, and abutments h', with thehorizontal revolving brushes and the vertical revolving brushes arranged, substantially as shown, to receive the kegs from the said feed mechanism, substantially as described.
4. In a machine for scrubbing kegs, the combination, with housings E E', horizontal vbrushes d d, and rings d5, of the endless chain G and sprocket-wheels F F', substantially as described.
5. In a. machine for scrubbing kegs, the combination of the keg-discharging mechanism consisting of the revolving lifter 75,-having hooked arms k lc, and the inclined track llLwith the revolving brushes adapted to scrub the kegs and the conveyer for delivering` the kegs to the discharging mechanism, substan- -tially as described.
