specification of Letters Patent.

Application led July 29, 1919. Serial No. 314,095.

['o aZZ whom 'it may concern Be it known that I, ALuxANnEn S. Srnnu, a citizen of the United States, and resident of Chicago, Illinois, have invented certain new and useful Improvements in Packing- Machines, of which the following is a speciication.

My invention relates to means for packing and deliveringr such products as shingles so that they may be put up in bundles or packages ready for shipment.

'Ihe invention consists in the features and combination and arrangement of parts hereinafter described and particularly pointed out in the claims.

ln the accompanying drawings Figure 1 is a view in the nature of a diagram with parts in section showing the main features of the apparatus.

Fig. 2 is a. plan view of parts shown in Fig. 1.

Fig. 3 is a View similar to Fig. 1 of a modification.

Fig. 4`is a view similar to Fig. 1 showing a member for beating up or truing the stack of shingles or the like.

Referring to Fig. 1 the shingle-s are delivered from the shingle forming machine on to a belt l, and I have indicated at m one of the shingles being conveyed by said belt and at 1/ I have indicated one of the shingles as delivered from the belt and about to fall onto the stack of shingles shown at z, which is being built up. The shingles as delivered from the belt 1 will strike a stop member 2- and will settle onto the pile or stack e. This stack is supported bv members forming a receiving table, there being two of these members, as shown at 3, 4, and each consisting of a series of arms or fingers separated from each other, as shown in the plan view, Fig. 2. Thesearms are carried by shafts 5 adapted to rotate, being ymounted in suitable bearingsy in the frame and these shafts are connected to rotate in unison b gears 6 mounted on the shafts. The table orming members are held against rotation by a stop '7 engaging one of the members and this stop is connected in any suitable way 'with counting mechanism so as to be withdrawnv at predetermined intervals. When the stop 1s withdrawn the table members will rotate, half a revolution, and the stack of shingles will be dropped between them when they reach the positions shown in dotted lines in Fig. 1 at a, .and the stack or pile of shingles w1ll beurecelved on a conveyer belt 8 which moves 1n a direction transverse with the direct1on of movement of the belt l, first men tioned, so that the stack of shingles will be carried away to a suitable point where the operator wil pack them up in bundles or box them up for shipment.

As above stated the table forming members or arms 3, 4, make a half revolution at each movement, therefore, when the stop 7 is wlthdrawn and the table members begin to move the stop is restored to its former ositlon before the half revolution of the ta le members has been accomplished s0 as to be ready to arrest the said table member when it has arrived in position to again su ort the shingles delivered from the belt 1. rom this construction it will be seen that first one arm or set of arms on one side of the shaft 5 will be in service to form the table and at the next half 4revolution the other arm or arms will be brought to the level to provide the shingle supporting table. The revolution of the table members is effected by a gear 9 on a shaft 10 having suitable bearings in the frame, the said gear 9 not being fixed to the shaft, but as shown in F 1g. 2, it is connected thereto by a spring 11 of any suitable form but in the particular machine illustrated this spring is of spiral form having one end 11 connected to the shaft and its other end 11x connected to the pinion or gear 9. It will be, therefore, understood that as the shaft 10 rotates it will wind up the spring without turning the pinion or gear 9 untll such time that the stop 7 is withdrawn, but during this period the tension of the spring will be stored up by the rotation of the shaft 10 and this tension will be applied tothe gear 9 and then as soon as the sto 7 is Withdrawn the gear 9 will be turned y the tension of the spring and will rotate the gear 6 with which it meshes and this will rotate the other gear so that both table members 3, 4, will be rotated in unison to deposit the stack of shin les or other articles upon the conveyer 8. he shaft 10 can be driven in any' suitable manner (not shown).

Referring to Fig. 3 instead of having rotary table members, 3, 4, I may employ Swingin table members 12, 13, pivotally mounte at their lower ends at 14 and having horizontal portions 15 to support the stack. A sto 2* is shown in this form of apparatus. his stop in both cases is in the form of a grating so that in the case of Figs. l and 2 the arms 3 can pass through this grating but the stop will furnish a side or guide member against which the stack may be built up. I prefer the form shown in Fig. l as the mechanism for operating the rotary table members is of the simplest character.

In Fig. 4 I show in addition to the rotary table membersa beatei` .arm 16 which is oscillated in any suitable manner.. so that when a shingle is delivered on to the pile this arm 16 will beat it up into'proper alinement with the rest of the pile.

I claim as my invention:

1. In combination a receiving conveyer, a stop at one side thereof, means at the other side for feeding articles in succession against the stop, and means between the stop and the conve er for receiving the articles as they are ed against the stop and for supporting such articles until a predetermined number have been delivered and for then dropping them onto the conveyer.

2. n combination a receiving conveyer, a stop at one side thereof2 means at the other side for feeding articles 1n succession against the stop, and means between the stop and the conveyer for receiving the articles as they are fed against the stop and for supporting auch articles until a predetermined number have been delivered and for then dropping `them onto the eonveyer, said means compris ingshafts at opposite sides of the conveyor, the shafts havin radial arms adapted to extend. transverse y of the conveyer and cooperating to receive the articles.

3. In combinationv a receiving conveyer, a stop at one side thereof, means-at the other side for feeding articles in succession against the stop, and means between the sto and the conveyer for receiving the artic es as they are fed against the stop and for supporting such articles until a predetermined number have been delivered and for then dropping them onto the conveyer, said means comprising shafts at opposite sides .of the conveyer, the shafts havin radial arms adapted to extend transverse y of the conveyer and coperatin to receive the articles, said arms being re atively long and the shafts being so spaced above the conveyer as to cause the arms to engage the lowermost article of the stack until it is near the conveyer whereby to prevent the disturbance of the stack as it is delivered to the conveyer.

In testimony whereof, I aiiix my signature.

WILLIAM HARTMANN, ALEXANDER Banane.
