MACHINE FOR SETTING UP CARTONS.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed January 29.1907- Serial NO- 354,76@

Tolfall whom it may concern:

f Be it known that I, THOMAS ROMER WEYANT, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Machines for Setting Up Cartons, of which the following is a specification.

A ll'lvhis invention relates to machines for setting up cartons and particularly to the means employed-for feeding cartons singly, in a fiat or knocked down condition, into a guideway or passage where they are operated upon by certain mechanisms to bring them into rectangular form and to fold and seal their end flaps.

I will describe a preferred embodiment of my invention and then point out the novel features in claims. In the accompanying drawingsz-Figure l is a plan view of the receiving end of a machine for setting up l cartons, embodying my invention. Fig. 2 is a similar view showing some of the parts in a different position Fig. 3 is a front elevation of the feeding mechanism looking in the direction of arrow 3 on Fig. l. Fig. 4 is a side elevation looking in the direction of arrow 4 on Fig. l. Figs. 5 and 6 are sectional views of the feed box.

In an application filed by me November 9, 1906, Serial N o. 344,090, I have illustrated and described a machine for setting up cartons, in which a quantity of cartons in a fiat or knocked down form, are placed in a reservoir, pushed toward the front wall and discharged one at a time into the passage or guideway. My present invention provides means for receiving a single carton and moving it into vertical position against the4 front wall of the feed box in position to be pushed therefrom into the passage or guideway. The cartons may be fed singly by hand or otherwise to the receiving devices.

The feed box is indicated by l0 and comprises a front wall l1, side walls l2, 12l and bottom 13. A narrow vertical passage 14 leads from the forward end of the feed box into aguideway or passage 15. It will be observed that the front wall ll of the feed box and the narrow passage 14 are oblique to the guideway 15, so that a carton when pushed from the feed box into the guideway will extend obliquely across the latter, as indicated in Fig. 2. The cartons will be engaged by fiights 18 and moved along the guideway 15 where they will be opened up into rectangular form and have their end fiaps folded and sealed. It is unnecessary to describe in detail any of the mechanism which acts on the carton after it has been delivered into the guideway as this forms no part of the present invention, and has been fully described in the above named application.

Any suitable means may be employed to push the carton singly from the feed box into the guideway 15, and as shown I employ a push-bar 20 attached to a dovetail tongue 2l which slides in a dovetail groove in the front wall 1l of the feed box. The tongue is provided with a rack-bar 22 with which a gear 23 meshes. This gear is carried by a shaft 24 supported in suitable bearings and on the same shaft is a smaller gear 25 which meshes with a rack-bar 26. This bar is connected at one end to a crank rod 27 which in turn is connected to a crank pin 28 on a rotatable disk or wheel 29. The disk may be rotated by any suitable means not shown.

The front wall ll extends beyond the side wall 12XL in order to afford a substantial support for the push bar in its longitudinal reciprocations. It is obvious that with every complete revolution of the disk 29 the push bar 20 will make a full reciprocation.

A rock-shaft 30 is journaled in the side l2'l of the feed box and in a bearing 3l on a fixed part of the machine. This shaft is located just above the bottom of the feed box and a plate 32 is connected at its lower end to the shaft within the feed box in any suitable manneras by clips 33, and the plate will oscillate toward and away from the front wall ll when the shaft is rocked.

It is preferable to have the oscillation of the plate 32 controlled by the reciprocation of the push-bar, and in order to effect this I provide a cam' bar 34 rigidly connected to the rock shaft 30 above it and outside the feed box, by means of tie plates 35 or any other suitable means. On the push-bar a bracket 36 is secured, to which a roller 37 is adjustably secured in position to engage the cam bar 34 and cause it to rock the shaft 30 and move the plate 32 away from the front Wall 11, as indicated in Figs. 2 and 6. The plate 32 will normally be held in a substantially vertical position adjacent to the front wall 1l. by means of a plate spring 38 secured at its lower end to the extension of the front wall, or to any other fixed part of the machine, and its upper end loosely engaging the cam bar 34.

A series of pins 39 project inwardly from the front wall 1l just above the rock shaft 30 and extend through slots 40 in the lower end of plate 32. These pins serve to support the lower end of the carton and the slots permit the plate to move away from the wall 11 without interference by the pins. The extent of movement of the plate away from the wall l1 is limited by a cross bar 4I secured to the feed box in any suitable manner.

The operation is as follows: Assuming the parts to be in the position shown in Fig. 2 with a carton just pushed out into the guideway 15 and the plate 32 in the position shown in Fig. 6, the push bar will be just starting on its return movement. The operator will now put a carton on the inclined plate 32 in the feed box with its lower end resting on the pins 39. As soon as the roller 37 reaches the curved portion of the cam bar 34 the spring 38 will gradually move the plate 32 toward the front wall 11 and when the roller 37 passes entirely off the bar 34 the plate 32 will be in substantially vertical position with the carton in a similar position between the plate and the iront Wall. Whenthe push bar again moves toward the guideway it will push the carton ahead of it through the narrow passage 14., and since the roller 37 will not act on the cam bar until a considerable portion of the carton has been pushed into the passage 1.4, the latter will hold the carton in vertical position when the plate 32 begins to move away from the carton.

Obviously by a slightly different arrangement oi the parts the spring could be used to move the plate to inL clined position and the cam bar to move it to vertical position.

I do not limit myseli to the precise details of con'- struction illustrated and described, but
