WILLIAM MACNAUGHTAN, OF BRGOKLINE, MASSACHUSETTS, ASSIGNOR TO PACKAGE GONFECTIONERY COMPANY, A CORPORATION OF MASSACHUSETTS.

DUMPING-MACHINE.

Application filed January 10, 1913.

To all whom it may concern Be it known that I, VIILLIAM Mac- NAUGHTAN, of Brookline, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Dumping-Machines, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.

This invention has reference to an improved machine for dumping candy wafers and similar frangible articles from a series of trays. or holders, in or on which the articles have been subjected to one step in the process of their manufacture, to receivers in which said articles conveniently may be stored or transported.

The main object of the invention is to so construct a machine of this nature that the wafers or articles may be dumped from a series of trays or holders without breaking the said wafers or articles.

Another object of the invention is to facilitate the dumping of a large number of such trays or holders.

Other objects of the invention will appear from the following description.

The invention consists in the means for receiving the wafers or articles from the trays and the devices for controlling the movement of the wafers or articles.

The invention also consists in such other novel features of construction and combination of parts as shall hereinafter be more fully described and pointed out in the claim.

Figure 1, represents a side elevation of the improved dumping machine, parts thereof being broken away. Fig. 2, represents a back view of the machine, parts being broken away. Fig. 3, represents a vertical sectional view taken on line 33 Fig. 2, the machine being shown in the dumping position. Fig. 4, represents a perspective View of portions of two of the trays used with this machine. Fig. 5, represents a view of a wafer referred to herein.

Similar reference characters designate corresponding parts throughout.

In the manufacture of sugar wafers, so called, the wafers are stamped or cut from a sheet of material and are delivered or placed on trays a, a usually of wood and having the spacing strips 6, b. The trays a, a are arranged in a stack on a truck 0 and, in such arrangement the spacing strips 5, b

of the several trays receive and support the trays a, a next above out of contact with the wafers. The stack of trays is then moved by means of its truck 0 to some convenient point or machine at or in which the wafers may be treated by currents of air or otherwise without disturbing the wafers on said trays; after which it becomes necessary, in some cases, to dump the wafers from all of said trays into one or more receptacles for transportation'to some point at which the packing of the wafers in rolls or some other operation is carried out. It is to be understood that the wafers are very thin and, at the time of their removal from the trays as, a, extremely brittle, and that breakage of the wafers is to be avoided.

In carrying this invention into practice I construct the chamber 5 open at one side and of a size to receive a truck 0 and its stack of trays a, a; the back 6 of this chamber is adapted to form a chute and adjacent said back at one end of chamber 5 is the opening 7 closed by the hinged flap 8. Pivotally mounted within said chamber 5 is a series of gates 9, 9 having their free edges adapted to swing toward the back 6 to form barriers across the chute formed by said back. Provision is made to swing said gates 9, 9 and, preferably, such movement of the gates is effected simultaneously by the cord or rope 10 connected with all of said gates and eX- tending to some convenient point outside the chamber and fastened.

The chamber 5 at its exterior has the studs 11, 11 which are journaled in bearings of the frame 12 whereby the chamber 5 is so sustained that the truck a and its stack of trays a, a conveniently may be moved into said chamber while said chamber is held from swinging movement by the spring operated catch 13 which engages with the pawl let on said chamber 5. In order to facilitate the swinging of chamber 5 I pro vide one of the studs 11 with the gear 15 which is engaged by the teeth of the smaller gear 16 having a shaft, which is journaled in a member of the frame 12, and is provided with the handle 17 I also provide a. counter weight device which preferably consists of the rope 18 attached to said chamber 5 and extending over suitable pulleys to the weight 19.

With the chamber 5 in the upright position shown in Fig. 1 the truck 0 with its Patented July 2?, 1915..

stack of trays t, a is pushed into said chamber, care being taken that the spacing strips 3),?) of all the trays are located at the sides of said traysso that the slidingmovement of the wafers from said trays, when said trays are tilted, shall be unobstructed toward the back 6 of chamber 5. The catch 13 is now released and the chamber 5 is swung by means of the handle 16 or otherwise until the back 6 is'inclined and the end ofchamber 5 having the opening 7 is lower most. In such swinging movement of chamher 5, the stack of trays a, a is swung so that said trays become inclined and the wafers slide therefrom into the receptacles formed by the gates 9, 9 which are so spaced apart that each of said receptacles receives the wafers from but a few of the trays while the distance through which the wafers move is not sufiicientto result in any undue jar thereof that would result in their fracture. By drawing on the rope 10 all the gates 9, 9 may now be swung whereby the chute, formed by the back 6 of chamber 5, is opened and the wafers are free to pass down said chute and through the opening 7 into recep- Copies of this patent may be obtained for tacles as d placed to receive them. lhe ultimate discharge of the wafers being controlled by the hinged fiap 8. After such dumping operation the chamber 5 is swung back to its original position and latch 13 operates to engage pawl 14 and hold said said wall, and means for swinging said gates to open a passage along said wall, substantially as described.
