Applicationflled July 17, 1980. Serial No. 468,681.

My invention relates to a nailing machine and more specifically to a nailing machine for nailing boxes and for nailing cleats on the box ends. Lugboxes-used for packing a and shipping fruit are formed with the end boards enlarged in height by nailing cleats to the top edge of said end boards. In use, lids are nailed on the top of the cleats. The object of the cleat is the easy removal of the lid together with the cleat so that when the box is opened it has the appearance of being "full even though the fruit may have settled in the box. The cleats used are usually the same approximate thickness as the thickness "of the end boards although sometimes they may be slightly thicker. It hasbecorne the practice in box construction to nailthe cleats on the box ends before the box is assembled and nailed. By reason of the fact that the end boards are sometimes less than three. fourths of an inch thick and because the grain in the Wood is gnarled or crossed, the nail driven through the cleat into the box end frequently runs out at the side and form what boxmakers call shiners, that is the pointed end of the nail penetrates through the side of the box end and sometimes is ex posed and sometimes through the side oi the cfiat so that it does not enter the box end at it 1.

V The object of my invention is to use guide means on each side oi? the wood to be nailed so that the point or a nail coming through the side'of the clest, or the box end is autoinatically reversed and starts the point away from the outside surface of the cleat or box end. @ther objects will be hereinafter disclosed.

In the drawing herewith Fig. 1 shows a front view of a part of a nailing machine showing my device clamping the end board and the cleat together for nailing. Fig. 2 is a fractional front view of the device shown in Fig. 1, showing the clamping means open and in positionfor receiving the box end and dealt Fig. 3 is a top sectional View of the device as shown inFigz-l along the sectional line 33-in Fig. 1. Fig. 4 is a view of the end board with the cleat thereon showing the- -nails driven therein in broken lines. Fig" lateral base 12, and cross supports 13.

7 that described in Patent No. 1355 225, dated April 22 1930 for a Compensating device 4a is an end view of the end board and cleat shown in Fig. 4. Fig. 5 is an enlarged view of a cross section of the end of board and the cleat showing the clamp in operative relation with the end board and cleat, and show-. ing a nail driven therethrough. Figs. 6 and 6a are modified forms of the clamp. Referring to the drawing, a frame is constructed of upright posts '10 and 11,.of K

table 14 connects uprights 10 and -11, runs parallel with base 125 and ispositioned a spaced distance from said base. A nail driving head 15 is positioned above thetable l4: as hereinafter more fully set forth. To the driving head is attached sliding bars 16, which sliding bars are adapted to slide through bearings 17 attached to posts 10 and 11 A shaft 18 extends from uprights 10 to 11 and is likewise positioned parallel with table it. The shaft can be rotated by a wheel 19. At each end of shalt 18 is a crankiltl which is pivotally connected with sliding hare 16 by connecting arms 21 so that by the rctation of shait l8 sliding bar it and driving head 15 is given a vertical reciprocat ing motion. A nail driver 22 is attached to driving head 15. The nail driving mecha= ni srn can be of the same general character as for nail drivin mechanism which was granted to inc. aid nail driving device can consist of a single driver or a plurality of aligned drivers.

To the table I have attached a bracket 25 which is positioned so that the base is at tached to table 14, and the upright portion 26 is adapted as a rigid guide for the sides of the end board and cleat. This guide extends slightly above the top of said end board so it likewise engages 'thecleat as shown. At the top of said upright portion 1s a block 27, said block being formed with horizontal cor-' rugations 28 on the face adjacent to the board. Bracket 25 also supports a pivot mounting 29, on which pivot mountingiis. .7

pivoted an upright arm 30. Arm 30 has a roller 31 ositioned on the upper end thereof.

Depen ing from driving head 15 is a cam l 32 which is adapted on the movement of the nailing head down and up to move arm 30 toward block 27, and to hold it in that position while the cleat is being nailed to the end board. Arm 30 is pulled away from said box end when cam 32 so permits, by means of spring 33. To arm-30 arenttached

blocks

34 and 35. I These blocks are mounted on

stems

340 and 350, which stems pass through holes in arm 30 and are held therein by

nuts

342 and 352. Compression springs 36 and 37 encircle stems 340 and 350, one end resting against arm 30, and the other end against

blocks

34 and 35. It will be noted that by this construction when the nailing head is moved downward arm 30 will be moved toward the box end boards by the engagement of cam 32 with roller 31, and the cam will press

blocks

34 and 35 toward block 27. In .1. proper adjustment of the parts, the end board and the cleat are clamped between said blocks.

The purpose of having two blocks, to-wit, 34 and 35 operate against block 27 is to compensate for the varying differences of thicknesses of the cleat and the end board. 1f the cleat were of the same thickness as the end board,

blocks

34 and 35 might be replaced by one block aproximatcly the same shape as block 27. Inasmuch as block 27 is positioned to engage both the end board and the cleat, block 34 is positioned to engage the cleat only and block 35 is positioned to engage the end. board only. By this means it is noted that the cleat and board on the one side will be held flush. The. springs 36 and 37 should be strong enough to hold the

blocks

34 and 35 tightly against the cleat and the end board, but should yield suificiently to permit of slight variations in the thickness of said cleat and end board.

To make the device more rigid I have supported a roller 40 on an upright support 41 in a position opposite to the roller 31 so that cam 32 passes between

rollers

31 and 40.

By this device it will be noted as shown in Fig. 5 that if for any reason a nail driven through the cleat toward. the box end board should emerge from the side of the cleat or board,

blocks

27, 34, 01-35 would tend to bend the point end of the nail. so that it would re-enter the cleat or board.

As shown in Fig. (3

blocks

271, 341, and 351 can have faces plane instead of corrugated.

In the drawing, 60 is the end board of the box, 61 is the cleat. 62 represents the nails fastening the cleat to the end board, 63 is the clutch forregulating the rotation of shaft 18, and likewise ton actuating the nail driving means at will, 64 is a foot pedal lever adapted to throw clutch (33 into operativerelation or out of operative relation.

Because of the action of the

blocks

27, 34,

and 35 these may be referred to in the claims jaws. In a broad sense, the block 27, and the upright bracket portion 26 might be 0011- sidered one jaw, While the

blocks

34 and 35, and the arm 30, upon which they are mounted, might be considered a second jaw cooperating therewith. I
