CAN-FILLING. MACHINE.

SPECIFICATION forming part of Letters Patent N o. 751,257, dated February 2, 1904.

Y Application filed December 17, 1902. Serial No. 135,479. (No model.)

T all whom t may concern,.- i i the box or table above the cans and provided in itsvbottom with rows of discharge-openings which register with the openings of the cans. A machine of this character is described and shown in another `application for patent tiled by me on or about the th day of November,

,1902, Serial No. 126,704.v If any of the stringbeans or other material remains in the hopper after filling a gang of cans, some ofthe surplus material is liable to drop into the box or upon the table upon withdrawing the tray of cans, rendering it necessary to remove such material from the box before thetra-y can be replaced y and incurring a corresponding loss of time.

' Which surround eccentrics D', securedto The object of my present invention is to provide simple means forovercoming this objection.

v In the accompanying drawings, Figure l is a sectional elevation of a can-filling machine embodying my invention. Fig. 2 is a top plan View thereof.

Similar letters of reference indicate corresponding parts in both views.

A indicates the stationary frame .of the ma-A chine, and B the vibratory box, table, or support, arranged lengthwise within the upper portion of the frame. This box may be supported and actuated by any suitable means; but the devices described and shown'in my prior application for patent, hereinbefore referred to, are preferably employed for this purpose. As shown in the drawings, they consist of upright rods C, pivoted at their upper ends to the under side of the box and provided at their lower ends with straps D,

l transverse shafts cl, the eccentric of one shaft being disposed oppositely to those of the other shaft to impart a rocking motion to the box. At the same time the box is vibrated longitudinally by an eccentric E and pitmen E', the eccentric being secured to a transverse shaft F, arranged at one endfof the machine.

- G indicates a removable tray seated in the box B and adapted to receive the gang of cans H to be filled. This tray preferably consists of a drawer, which is slid endwisethrough the open front end of the box and held in place during the operation of the machine by a turn-button e or other suitable means.

As shown in the drawings, the box B is f open at its top and comprises a bottom, side walls, and a rear or end wall. Upon the open top of the box rests a feed-hopper or box-like receptacle J, into which the material to be filled into the cans is placed. This hopper is provided in its bottom with rows of dischargelopenings e, which are arranged to register with the openings of the cans, respectively, as shown in Fig. l, so that the material drops into the cans and is caused to settle in the Y same by the shaking motion imparted to the box B in a manner common to this class of machines. vThe upper portions of these openings lare preferably tlared'or beveled, and the flared edges of adjacent rows of openings are arranged-in'close proximity to each other, as shown in Fig. 2, to facilitate the delivery of the material through the openings and'reduce as much as posslible the area of the imperforate portions of the hopper-bottom upon .which the material may find lodgment. This construction causes the material to be quickly directed into the openings and expeditesthe filling operation. In order toafford the desired thickness of stock to form such beveledged openings withouty rendering the hopper too heavy, the' latter is preferably constructedl of wood. As shown in the drawings, the feed-hopper is providedbeyond its rearmost row of discharge-openings with acontinuation or extension J', having a solid or imperforate bottom. This extension forms a pocket or shelf into or upon which any surplus beans or other material remaining in the hopper after filling a gang of cans is adapted to be gathered before withdrawing the tray of cans, thereby preventing such surplus material from dropping through the openings of the hopper into the drawer-compartment of the vibrating box and interfering with the ready replacement of the tray. In the preferred construction shown in the drawings the feed-hopper extends some distance beyond the rear end of the box B to form the gathering-pocket J and is hinged to the adjacent end of the box, so that it may be tilted rearwardly, as shown by dotted lines in Fig. l, for reliably retaining the surplus material in the pocket or extension of the hopper. The hopper may be temporarily held in its tilted position by a hook 1 and an eye 7a2, secured to the frame and the hopper of the machine, respectively, or by any other appropriate means. The hopper may be held down in place on the box by a similar fastening Z Z'. While it is advantageous to hinge the hopper to the box B, it may in some cases be rigidly attached thereto, and my invention therefore embraces both of such constructions.

In the use of the machine after a gang of cans has been filled any material remaining in the hopper is brushed or otherwise removed from the perforated portion of the hopperbottom and gathered upon its imperforate extension or shelf J The hinged hopper is then released from the box B at its front end, tilted and secured in that position by the hook and eye ,712', after which the can-tray is removed. As none of the surplus material is allowed to drop into the tray-space of the box, the tray after being refilled with empty cans can be immediately replaced in the box. After replacing the tray the hinged feed-hopper is lowered to its normal position and secured in place by the fastening Z Z the material gathered upon the extension J' is brushed back upon the perforated portion of the hopperbottom, and another charge of material is placed in the hopper.

My improvement also avoids the necessity of carefully measuring the quantity oi stock required for filling the cans of a batch, thus saving time and materially increasing the capacity of the machine.

I do not wish to claim in this application the actuating mechanism of the vibratory box yB or the sliding can-tray, as the same form the subject of the application for patent hereinbefore referred to.

I claim as my invention- 1. In a can-filling machine, the combination of a frame, a vibratory table or support for the cans, and a feed-hopper arranged above said table and adapted to vibrate therewith, the bottom of the hopper having rows of dischargeopenings arranged to register with the openings of the cans and an imperforate extension arranged beyond its perforated arca and in the plane of the bottom and upon which any surplus material is adapted to be gathered, substantially as set forth.

2. In a can-filling machine, the combination of a frame, a vibratory box or table, a removable can-tray arranged in said box, and a feedhopper pivotally mounted on said box and provided in its bottom with discharge-openings and beyond the perforated portion of its bottom with an imperforate extension, substantially as set forth.

3. In a can-filling machine, the combination of a frame, avibratory box or table, a removable can-tray arranged in said box, and a vertically-swinging feed-hopper hinged to one end of said box and extending rearwardly beyond its hinge, the portion of the hopperbottom in rear of its hinge being imperforate and the portion thereof above the can-tray being provided with discharge-openings arranged to register with the openings of the cans, substantially as set forth.

Witness my hand this 3d day of December, 1902.
