WILLIAM MCMURRAY, OF I-IIGHWOOD, NEW JERSEY, ASSIGNOR TO THE GENERAL PACKAGE COMPANY, A CORPORATION OF NEW YORK.

BOX-HING-ING MACHINE.

Original application filed. August 13, 1908, Serial No. 448,433.

To all whom it may concern:

Be it known that I, WVILLIAM MOMURRAY, a citizen of the United States, and resident of Highwood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Box-Hinging Machines, of which the following is a specification.

This application is a division of my application for patent for improvements in machines for hinging boxes, filed August 13, 1908, Serial No. 448,433.

The object of my present invent-ion is to accommodate relatively long boards upon the table that holds the boards in position for hinging them together, whereby part of the weight of the table and the working strains upon the table are borne by the floor upon which the lower end of the table rests; also to permit adjustment of the table with respect to the staple driving devices, while the lower end of the table may have proper movement upon the floor, and also to provide improved means to enable the table with its superimposed boards to be accurately preliminarily adjusted with respect to the staple driving devices and to the means for reciprocating the table while the boards are being hinged thereon.

The invention comprises novel details of improvement and combinations of parts that will be more fully hereinafter set forth and then more particularly pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein,

Figure 1 is a front elevation of a hinging machine embodying my invention; Fig. 2 is a side view of the machine looking from the right in Fig. 1; Fig. 3 is an enlarged front view illustrating my present improvements; Fig. 4 is an edge view thereof; Fig. 5 is an enlarged sectional view on the line 5, 5, in Fig. 3; Fig. 6 is a cross section on the line 6, 6, in Fig. 3, and Fig. 7 is an enlarged detail view of part of the table supporting and adjusting devices.

Similar numerals of reference indicate corresponding parts in the several views.

Serial No. 520,664.

ings indicates a suitable frame, the upper portion 1 of which carries suitable means for driving interlocked staples, such as shown in my said application Serial No. 448,433, or as shown in my United States Letters Patent No. 820,243 and No. 820,244, granted May 8, 1906.

At 2 is a table or support upon which boards or box parts are to be placed to be hinged together, which table is located below the staple driving and setting devices before mentioned. In order to accommodate relatively long boards upon the table the same is pivotally connected at its upper part with a vertically movable support 3, as by pivots at 4, and the lower end of table 2 is shown provided with rollers 2 to enable the table at its lower end to rest upon the floor, the arrangement being such that as the table rises and falls it will be partially supported by the floor, and thereby a portion of the weight of the table and the working strains are taken from the table supporting devices.

The support 3 is mounted for vertical movement as well as lateral adjustment. For this purpose support 3 is guided in vertical ways in a block 5, which is supported to have lateral movement in horizontal ways in a block 6, carried in guides 7 on frame 1, a screw 8 carried by a lug 5" on block 5 and co-acting with a lug 3 on support 3 serving to adjust the latter vertically with respect to block 5, a screw 3 passing through the slot 3 in support 3 and attached to or passing through block 5 serving by means of handle 3 to lock support 3 in positions of vertical adjustment. A hand screw 9 carried by block 6 and operating against block 5 serves to regulate the lateral adjustment of block 5 with respect to block 6. At its lower portion block 6 carries a roller or projection 10 adapted to bear upon a cam 11, secured upon shaft 12, journaled in bearings in frame 1, which cam raises and lowers the table during operation of the machine. At 13 is a cam loose on shaft 12 and provided with a handle 14, whereby said cam may be rotated to act upon roller 10 to raise the table for initial adjustment of the latter with respect to the boards as, y, to be operated upon by the staple drivlng devices, whereby the parts of the table support may be ac curately adjusted primarily with respect to such boards, and cam 11 will continue to control the up and down movements of the table in accordance with such adjustment, the boards being clamped as the table rises between the abutments A, A The abutment A may be formed directly on the frame or head of the machine, while the abutment A located at an angle to the abutment A is made adjustable substantially in the plane of the edge of abutment A, and constitutes a clench block for horizontally driven staples. Said abutment or block A is shown guided on a support A and adjusted toward the table by a screw B, and held in adjusted position by a screw C and nut D working in a slot 0 (see Fig. Such adjustment of the abutment or clench block A provides for different thicknesses of boards placed upon table 2 to be clamped in the angle or apex of recess E. As the table is to be raised and lowered each time two staples are interlocked to form a hinge, shaft 12 for this purpose is given an intermittent motion by means of suitable gearing. In the example illustrated said shaft carries a gear 15 meshing with an idle gear 16 journaled on frame 1, which also meshes with a gear 17 on a shaft 18 that carries a gear 19 meshing with a gear 20 carried by a shaft 21 having fast and loose pulleys 21 21*, which shaft 21 may also be operated by hand by a suitable handle 21 (Fig. 1) for use in adjusting the parts. Gear 19 is loose on its shaft 18 and adapted to be thrown into connection therewith as desired by a clutch, indicated generally at 22, which may be substantially of the character set forth in my aforesaid patents, in the illustration herein said clutch being provided with an arm 23 adapted to be operated by a lever 24L connected by a link 24 with a suitable treadle 24 whereby by operating said treadle shaft 18 and cam 11 may be given intermittent rotation, or one rotation for each complete operation of driving two interlocked staples.

By the arrangement set forth, the table may be readily and accurately adjusted with respect to boards laid thereon, as indicated in Fig. 3, by placing the boards in position one upon the other, and against a suitable adjustable guide or stop 2* on the table, loosening the screws 8, 9 and handle 3, and then operating cam 13, by means of lever 14, which will bring the block 6 to the proper elevated position by raising roller 10 out of the depression 11 of cam 11 in which such roller rests in the inactive position, and thereupon as the boards press against the abutments A, A as the parts are raised and also as screw 8 is turned, said boards will find the proper seat in the angle E, block 5 then sliding laterally a proper distance, and then the support 3 and block 5 will be locked by turning handle 3, and screw 9 will be set up against the side of block 5, and then said parts will all remain in their proper positions, cam 13 then being turned back, as in dotted lines in Fig. 1, to permit cam 11 to continue to raise and lower the table during operation of the machine, cam 13 only raising block 6 as high as cam 11 can raise said block during operation, cam 13 thus always determining the proper position of the table parts with respect to the action of cam 11 for boards of varying thickness.

It will be understood that during the time that cam 11 raises the table so that the boards upon the table are pressed against the abutments at the angle E, the staple setting and driving devices will operate to drive interlocked staples into the boards upon the table, and that after a pair of staples are driven, and as soon as the recess 11 of cam 11 next comes under proj ection 10 the latter will ride down into said recess (the clutch now uncoupling the gearing by reason of the previous release of treadle 2 1 and the table will descend lowering the box parts from engagement with the abutments above and the parts will come to rest, and when the treadle is again depressed the operation will be repeated, and so on.

Having now described my invention what I claim is:

1. The combination of a frame, a support carried thereby, and a table movably connected with said support and adapted to coact with a separate support to have independent motion by and during the movement of the table support.

2. The combination of a frame, a support guided thereon to have vertical movement, means to raise and lower said support, and a table pivotally connected with said support and adapted to have independent movement during the rise and fall of said support. 3. The combination of a frame, a support, means to permit vertical and lateral adjustment of said support, means to cause said support to be raised and lowered, and a table pivotally connected with said support and having its lower end adapted to be supported by the floor.

1. The combination of a frame, a table, a support therefor, a cam to operate said table, means for intermittently operating said cam, and a loose cam independent of said means and arranged to be operated by hand to preliminarily adjust said table in position coincident with its position at the time of maximum upward movement by the first named cam.

5. The combination of a frame, a table,

a reciprocative support for the table, a cam to operate said table, gearing to operate said cam, means to cause intermittent operation of said cam, and a loose cam independent of the first named cam t0 preliminarily adjust said table co-extensively With its movement by the first named cam.

Signed at New York city in the county of New York and State of New York this 23rd day of September A. D. 1909.
