Application tiled October 8, 1898.

.To @ZZ whom t may concern Be it known that I, JAMES Das BRIsAY, a citizen of the Dominion of Canada, residing at New Westminster, in the Province of British Columbia, Canada, have invented a new and useful Improvementin Can-Washin g Machines, of which the following is a specification.

My invention relates to improvements in machines for washing the grease from cans preparatory to being covered, so that the iux will properly seal the caps; and the object of my improvement is to provide a machine of this class that is cheap to make and simple to operate and that will efficiently Wash a large number of cans in a short space of time and which may be also adjusted to wash cans ofl different dimensions.

I attain the above object by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of a machine constructed in accordance with my invention, taken practically on the line 1 1 on Fig. 2, parts being shown in elevation. Fig. 2 shows a plan of the machine. Fig. 3 is an enlarged elevation of' the can spacing and feeding mechanism. Fig. 4 is a plan of the machine with the top removed to line 2 2 of Fig. 1. This shows the position and adjustment of the brushes on either side of the can-track. Fig. 5 shows a section of the water-box on line b b, Fig. 4. Fig. 5u is a detail sectional View of a portion of the mouth of the waterbox. Fig. 6 is a sectional detail of the device which secures the outer wiping-brushes. Fig. 7 shows a detail of the slidable pin in the trigger mechanism, and Fig. 8 shows an enlarged det-ail of the trigger which retards and spaces the cans. Fig. 9 is anend view of my can-washing machine. Fig. 10 is a detail view of one of the brackets 49 49, hereinafter referred to.

Similar numerals refer to similar parts throughout the several views.

The frame is comprised of a horizontal portion l0, supported by the legs 10a, and a column lOb, projecting upward for a suitable distance above the horizontal portion 10. Suitably journaled in the legs 10a is a horizontal shaft 1l, and placed at right angles to this shaft and passing through and journaled Serial No. 693,012. (No model.)

in the horizontal part of the frame10 are shafts 12 and 13, these being rot-ated at the same speed as the shaft 11 by the bevelgears 14 and 15, respectively.

Securely bolted to the horizontal part oit' the frame 10 is a circular table 16, having openings therein to receive the column 10b and the boss for the shaft 12.

Arranged to turn on the column lOb is aro tary table 17. Secured to the lower end or sleeve of this table is a toothed ring or gear 18, which meshes with a gear-wheel 19, secured on the upper end of the shaft 12. The diameters of the gears 18 and 19 should be two to one, respectively, for a reason to appearlater.

Quadrically arranged in the table 17 are pockets 17 a, and arranged in these pockets are vertically-movable plungers 20, the same being also arranged to rotate in the pockets. Depending from the bosses of the plungers 2O are stems 21, on which the plungers turn, the said stems being held in place by pins lying in annular grooves 21f in the same and passing through openings in theI bosses of the plungers 20, as 20a.

Pivoted to projecting webs on the under vpart of the table 17 and passing through openings in the depending ends of the stems 21 are radial arms 22, and on the ends of these arms 22 are rollers 23, the same taking around a track 24, which is rigidly supported by brackets 25 and 26. (See Fig. 1.)

Supported by a bracket 27 is a crescentshaped frame 28, over which a can-feeding belt 29 is passed, and movement is imparted to this belt by its being passed beneath a pulley 30, ixed on the drive-shaft 11, and over idlers 31, journaled in a frame 32, which is secured to the. leg of the frame 10u.

As better shown in Fig. 4, securely bolted to the outer side of the frame 28 is a can-guide frame 33, which projects inward over the belt' 29 toward the column 10b, and secured to the said column is a frame 34, which projects outward, the two frames being divided by a space 35 and the opposite sides of these frames having concave contours for guiding the cans into and out of the machine, as 36 and 37, respectively.

Securely bolted to the top of the column 10b is a frame 38, the outer edge of which is an IOO arc of a circle concentric with the shaft 13. On the outer rim of this frame 3S are securely fixed brushes 39, which project beyond the path of the inner circle described by the revolving cans. By reason of the set-bolts 40 passing through the slots 3S and into the column 10b and the shaft 13 passing through the slot 38b it is obvious that the brushes 39 may be set in or out to engage the surfaces of cans of dierent diameters.

Placed on the outer side of the path of the cans is a water-box 41, supported in its proper position by standards 42 and 43. The waterbox, which is composed of sections, as clearly shown in Fig. 5, is arranged with two ejectingmouths for the hot water, these being placed tangential' to the outer path of the cans, as 41 and 41h. By referring more particularly to Figs. 5 and 5 it will be noticed that the water-box is wedge-shaped and its mouth contracted to form a jet-discharge, and to regulate the said discharge a wedge-shaped blade 41c is provided, which is adjustably held on the mouth of the box by means of screws, one of which, 41, is shown and which passes through an elongated slot 41h in the extended lip 41 of the mouth, such arrangement of parts enabling the operator to readily set the water-box mouth to throw the desired Volume of water against the passing cans. The water-box may be set at any desired elevation by the small set-bolts 44 taking through slots 43 in the said standards and threading into lugs 41e on each end of the water-box. (See Fig. 5.)

Placed at some distance around the table 17 and at the same distance from the center as the standards 42 and 43 is a standard 45, and fixed to the standards in a similar manner to the water-box is a brush-holding frame 46. This consists of the upper angle-iron piece, being secured to the angle-iron standards, as shown, and an under flat piece bolted at intervals thereto, the brushes 47 being suitably held between the bolts 48, with their whisking ends extending into the path of the cans.

Placed between the pockets 17 and securely fixed to the table 17 are can-guards 49, the opposite ends of which engage and prevent the-cans from being shaken from their proper position on the plungers or supports 20.

Resting on and secured to the upwardlyprojecting webs of the can-guards 49, as 49, is a disk or ring 50, and arranged in the ring directly over the pockets 17 in the table are spindles 5l, the same being arranged to turn in suitable bossed bearings. On the depending ends of the spindles are disks or closure members 51, which are designed to fit over the inout-hs and close the cans while being washed. Introduced between the disks 51 and the ring 50 and wound on the spindles 51 are springs 52. These press the disks downward upon the cans, and by reason of the track 24, which causes the cans to be elevated, being of uneven plane on the side of the machine where the water-box and brushes are located the cans are driven up to the highest ing inserted into the can-mouths.

plane and engaged by the disks 5l before the cans engage the brushes, and consequently the springs 52 will impart the desired pressure on the cans to hold them firmly, the contracted lower central portions of the disks be- Securely fixed to the spindles on the upper side of the ring 50 are pinions 53, and these mesh with a gear-wheel 54, which is keyed to the shaft 13. It is obvious from the foregoing that as the table 17 is rotated the spindles 51 and disks 51, engaging the cans, will be rotated at a much higher speed than the table, and consequently the cans will be rapidly revolved against the stationary brushes 39 and 47.

As better shown in Fig. 1, the cans are delivered from the belt 29 to their respective seats on the plungers 2O while such plungers are depressed to their normal position; but as the table moves around the rollers 23 on the radial arms 22, which control the vertical movement of the plungers, will take up the incline on the track 24, and before the can on such plunger comes to the side of the machine occupied by the Water-box and the brushes its top will be engaged by the revolving disk 51a and be revolved thereby, and as it is passed around it will be depressed and disconnected from the disk 51, when the can Will be pushed around the concave 37 of the guides 34 and 33 to the belt 29.

To provide for the plungers being depressed to their lowest plane ou the side of the machine where the cans are received, so that such can will slide thereon without obstruction, a depressing-rail 55 is secured to the inner side of the bracket 27, which causes the rolls 23 to follow their proper track 24, and thus insures the plungers 2O being depressed.

As illustrated in Fig. 2, the cans are fed to the machine on the belt 29, and they are released into the machine by a spacing mechanism. This consists of a trigger 56, which is pivoted on a pin 57, rigidly fixed in a slot 281. (See Figs. 3, 4, 7, and 8.) At the rear or inner end of the trigger is a slot 56, in Which is a sliding pin 58. This pin is held in place by the collars thereon above and bei low the member 5G and is allowed to slide back and forth for a reason to appear. Passing vertically through the brackets or frames 28 and 33 and a bracket 59, secured to the idler-frame 32, is a shaft G0, the same having a beveled gear 61 secured on its lower end, which meshes with a like gear 62, secured on the main drive-shaft 11. Secured to the top end of the shaft GO and with its boss resting on the bracket 33 is an elliptical cam 63, the under side of which is provided with a groove 63. Arranged intermediately between the pin 57 and the shaft GO is a pin (i4, this being adj ustably fixed in a slot 2S". Fulcrumed on this pin 64 is a lever 65, the outer end of which lies against the inner side of the slidable pin 58, and its opposite end is provided with an upwardly-projecting pin 65X, which lies in the groove G3 of the cam G3.

Coiled around the pin 64 and with its inner end resting against a stud 65a and its opposite end lying against the slidable pin 58 is a spring 66, (see Fig. 8,) and coiled around the pivot-pin 57 of the trigger and with one end resting against the slidable pin and the other end on the inner side of a stud 56b is a spring 67. These springs 66 and 67 are to hold the slidable pin 58 to the inner end of the slot 56a, which is its normal position, and as the cam 63 is turned the pin taking around the groove 63a therein will cause the lever 65 to oscillate, and by reason of the springs 66 and 67 holding the pin against the inner side of the slot 56a and the end of the said lever, the

trigger-fingers 56c will be thrown alternately into the path of the cans, and the same will be thereby spaced, as shown in Fig. 2. In the event of a can being caught by either of the fingers 56c the slot 56 will allow the finger being thrown backward, and should a can be caught by each of the fingers at the same time the lever 65 will either leave the pin 58 or the said pin will be forced along the slot 56a, according to the direction, the end of the lever 65 is moving.

Pivoted near the opposite edges of the major axis of the cam 63 are resilient arms 68. The inner ends of these arms 68 are held against the opposite sides of 'the shaft 60 by springs 69. These springs 69 are secured to pins 70 on the opposite projecting ends of the arms 68 and are coiled around the pivot-pins 71 of the arms, and their inner ends lie against the shaft 60, the strain being exercisedto cause the inner ends ofthe arms 68 to hug the shaft 63 tightly, so that as the cam swings around the projecting ends of the arms 68 will engage the cans and push them to and from the rotary table 17, and consequently from and to the belt 29. If a can is caught by one of the arms 68 before its opening be'- tween the brackets 49, and consequently the plunger 20, on which it rests, has arrived at the point where it can be received, the arm so engaged will spring back and allow the can to pass around without damaging the said can. As each can is pushed over the plunger 2O the guard-bracket 72 pushes the can to its proper place.

When it is desired to adjust the machine to operate on cans of another dimension, the trigger mechanism 56 is moved in or out the desired distance by moving the pins 57 and 64 in the slots 28a and 28". The guard 72 on the opposite side of the belt is moved in a like manner, and the frame 38, carrying the brush 39, is moved in the desired direction to properly scrub the periphery of the cans.

The brushes 47 do not require moving, eX- cept as they become worn, as they are more in the nature of pliable brooms for whisking the water from the cans.

rlo adjust the machine to wash cans of different lengths, the brackets 49 are changed for ones having the upwardly-projecting webs of a proper length so as to reducek or increase the distance between the disks 51a and the table 17, and the gear-wheel 54 is moved up or down and secured on the shaft 13 to engage the pinions on their new plane. The faces of the pinions may be of sufficient width to allow of the desired vertical movement without disconnect-ing the wheel 54.

In the operation of myimproved can-washing machine motive power is imparted to the pulley 73, which is loose on the shaft 11. By coupling the clutch 74, operated by the lever 75, the machine is put in motion in the direction of the arrow; but owing to the central shaft 13 being driven direct from the driveshaft 11 the pinions 53 travel therearound in the opposite direction to that in which it is traveling, and thus the said pinions have a planet movement therearound, revolving at a much higher speed than they would otherwise be revolved from a stationary gear. y The belt 29 is put in motion by being passed beneath the pulley 30 and over the idlers 31, as aforesaid. The cans are placed on the said belt and are spaced, and owing to the cam 63 passing around twice for each revolution of the table four cans will be fed to the machine during such revolution. As each can comes to the point where the track 24 rises such can will be driven upward, engaged and rotated by the disk 51, and delivered to the same belt from which it was taken with all grease and oily matters removed therefrom.

The hot water or steam is furnished to the water-box 4l th rough the pipe 7 4a under pressure, and this will cause a steady spray to be thrown onto the passing cans through the narrow fiat openings 41 and 41", as before stated.
