BOX-C LEAT-NAILING MACHINE.

Application filed May 27, 1925. Serial No. 33,102.

This invention relates to an improvement in box cleat nailing machine of the type more particularly employed in nailing vooden cleats about the edges of a sheet of veneer to form the walls of a box, and the object of this invei'ition is to provide in such a machine a side gage to cooperate with the back gage to assist in positioning the short cleats and also to determine the extent of overhang of the veneer for the reception of the long cleats prior .to the nailing operations.

With these and other objects in view, the invention consists of certain novel features 01" construct-ion as will be more fully d2- scribed, and particularly pointed out in the appended claims.

In the accompanying drawings Figure l isa perspective view of my improved adjust-able gage.

Figure 10 is an edge view of the nailing machine table showing the position taken by the veneer and cleats in positioning the long cleats after the first operation 01": nail ing the short cleats to the veneer.

Figure 11 is the same as Figure 10 illustrating the back gage against which the long cleat is positioned with one end lying against the side gage and the veneer shown in dotted lines as positioned by the two gage-a to be nailed to the long cleat Figure 12 is a perspective view showing one type of box formed on the nailing machine with my improved type of gage in which the cleats are positioned about the edge of the sheet of veneer and on the outside of the box.

It is toundin the practical construction and operation of cleat nailing machines of this character, of advantage to provide a side gage on the table of the nailing machine to cooperate with the back gage thereon whereby the cleats upon being positioned on the table are first pressedagainst the back gage and then forced endwise until their ends abut against the edge gage, the t-lllCliness of this edge gage being substantiallv that of the cleait; next the sheet of veneer is placed on the cleat With its rear edge against the back gage and is then carried sidewise until its side edge extends beyond the cleat to overhang the same and engage the upper side gageblock, the overhanging portion being justthe width of the long eleat which is to be subsequently nailed against this overhanging edge. As soon as the veneer is in position against both the back and side gages, the foot operating pedal ispressed and the nailsare fed to and driven through the veneer and the cleat, their points extending into the space below the cleat. The continued operation of the machine thenlowersthe table with its work also the hammers bringing the points of the nails into contactwith theri ieting blocks which turn these points over into the under face of thee-l the table then returns to itsorigie1 ready for arepet i n etoperations sect of yen er with its cleat nailed ,to

veneer with its short cleats is now turned half way around with its overhanging edge extending over the long cleat and the ends of its short cleat abutting the side edges of the longer cleat and these short cleats are caused to abut against the edge gage thus positioning the veneer relatively to the short cleat to receive the nails therethrough. This operation is repeated to nail the long cleat on the opposite edge of the veneer, which completes the nailing of these four cleats to the veneer to complete onewall of the box to be subsequently assembled; and it is found in practice by the use of my improved side which performs four fund tions, firstto assist in positioning the end of the short cleat, then to determine the amount of overhang of the veneer, and third to position the long cleat and finally to position the veneer with its short cleat ready to be nailed to the long cleat thereby greatly facilitating these operations of the machine permitting very rapid and most accurate work to be prouuced; and the following is a detailed description of the present embodin'ient of my invention showing one construction of gage by which these advantageous re sults may be accomplished lVith reference to the drawings designates the table of a nailing machine which is provided with a back gage 11 on its face and is provided with openings 12 in this face to receive the riveting plate 13, this table 10 being adapted to support the cleat 13 and after the nails have been driven through the veneer ll and this cleat 13 by hammers 15 the table is dropped by a movement of the slide 16 thereby presenting the pointed end of the nail to the riveting surface 13 which cooperates with the continned downward stroke of the hammers to turn the pointed ends of the nails over into the under face of the cleat.

It is found in practice of great advantage in operating a nailing machine of this character to provide, in addition to the back gage 11, side gage 17 so that the cleat upon being deposited upon the table and pressed against the back gage 11 may he slid endways until its extremity contacts with this gage 17 whereby the cleat is accurately positioned to receive the veneer plate 14 to be nailed thereto. To accomplish this in a simple and effective way, I have provided an L-shaped bracket 18 having one varm 19 slotted and extending down along the edge of the table 10, the same being bolted thereto at 20 through this slot whereby a vertical adjustment of. the side gage may be obtained to accommodate cleats of different thicknesses, the other arm 21 of this bracket is slotted as at 22 and provided on its under side with a pair of parallelly spaced side walls 28 between which a binding nut 2a is arranged to slide longitudinally, but is prevented from rotating.

This side gage 17 comprises a lower gage block 25 having a longitudinal groove 26 in its lower face for the reception of the arm 21 of the supporting bracket on which this block 25 may be adjusted. On the upper face of this block, I have formed a guide rib 27 on which is adjustably mounted an upper guide block 28. Through this rib is formed an elongated slot 29 and this upper guide block may be adjustably secured in position on this guide rib of the guide block by means of a bolt 30 which ontends down through both blocks and is threaded into the nut 2i below, this nut being provided with an operating handle 31 above, by means of which both of these blocks may be secured simultaneously in adjusted position by a single operation of this handle.

It will be noted that the thickness of this lower gage block "25 including its guide rib 27 or that portion thereof extending above the face of the table is substantially that of the thickness of the cleats being op-- erated upon, whereby when the cleat is in position with its end abutting against this lower gage block its upper surface comes substantially flush with the, upper surface of this block so that when a sheet of veneer is placed upon this cleat its upper edge'may overlap the end of the cleat to engage the surface of the upper gage block which is setback from the front edge of the lower gage surface a distance substantially that of the width of the long cleat to be next nailed into position thereto, and the positioning of this upper gage block may be readily and accurately determined to correspond to the width of the long cleat to be employed, by the graduations on the edge thereof by means of which it may be set to permit the proper overhang of the veneer so as to accurately receive the next cleat to be nailed thereon.

My improved gage is very simple and practical to construct and may be quickly adjusted whereby cleats of various widths and thicknesses may be very accurately positioned, whereby the machine may be operated with great rapidity and accuracy.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood thatl reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1.
