.BOX-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 276,726, dated May 1, 1883,

Application filed January 26, 1883. (No model.)

To all whom it may concern:

. Be it known that we, THOMAS L. SMITH and WILLIAM S. Dore, both citizens of the United States, and residents of Brooklyn, Kings county, New York, have invented certain Improvements in Nailing-Machines, of which the following is a specification. V p

This invention relates to certain improve ments in the ordinary box-nailing machines, whereby the punches, nail holders or dies, and the stops for the end of the box may be moved simultaneously and instantly in or out, so that the nails may bedriven through the box side or bottom at different distances from the ends thereof. The main object of this construction is to permit one end of the box to be brought out flush with the ends of the sides when it is nailed fast, and-the other end to set back, so as to form a shallow recess in one end pot the box. This is required at times in order to protect labels pasted on the recessed box end against being rubbed off or defaced.

In nailing boxes it is necessary that the nail which passes through the side or .bottomshall enter thethickerend about midway of its thickness. Consequently, when the machine is provided with one guide-stop for both the box end and the side or bottom to be nailed thereto, the end will be flush with the edge of the side, and the punches and nail-holders will be set to drive the nails at that distance from the edge of the side which is necessary to cause them to enter the box end properly-thatis to say, it the box end he one inch thick. the nails will be driven through the side about half an inch from its end. Now, if we propose to recess the end of the box, the stop guide or guides for the said end must be projected out to the depth of the recess, and the punches and nail-holders must be set out proportionately; and as only one end of the box is usually to be recessed, and both are to be nailed in'rapid succession on .the same machine, it is desirable that theshit'ting of the parts should be capable of accomplishment simply and instantaneously. This is the object of our present invention, which we will now describe.

In the drawings which serve to illustrate our invention, Figure l is a sectional elevation of the upper part of a nailing-machine provided with our improvements. Fig. 2 is a rear elevation of one-half of the same. Fig. 3 is a front elevation of one-halfof the same, and

as these have no bearing'on our present invention. E E are the nail holders or dies; F, the pipes which convey the nails from the feeders to the dies; and a a are the punches actuated by the cross-head C. All of the above parts,

-anism, nor the lower portion of the machine,

perse, are common in this class of-nailing-machines, and we only show them here in order to illustrate our improvements.

On the inside of sideframes, A, are secured tougued bearers or guides b, on which are mounted the channeled bases 0 of a frame, G, which is thus made capable of a horizontal :movement back and forth on b.

H is a channeled bar, provided with tongues at its back, which engage and play in slots (Z in thefra me Or, being secured by plates c. This bar embracesor takes over the cross-head 0 above and below (see Fig. 1) in such amanuer as to compel it to move up and down with said cross-head, while it is free to move to and fro with the frame G on its guides b. The sockets f of the punches at are mounted on the bar H and held in place by the construction and means illustrated in Fig.1-that is to say, each of the sockets f has a tongue, g, which takes into a channel in the lower lip of the bar H, which brings the top of the socketflush with the upper face of said lower lip. The cross-head has or may have a pendent lip, i, to take over the faces of the said sockets. Then the punches are once set at the right intervalsfor the proper spacing of the nails their lower ends will rest in the dies E and never lift out of the same, and the cross-head will rest on the socketsf and prevent any movement vertically orlaterally. The bases 0 of frame G are extended to the front, and have a averse sockets j on their ends to receive a bar, is, on which the dies E are mounted. Any desired number of punches and dies may be employed, and they may be adjusted or spaced to suit the circumstances of the case.

On lugs l, which project from the rear of frame G, is mounted a plate,m,provided with twopendentbranches,m, and in these branches are screwed guide-stops a n-two in each, by preference-which are in the nature of rods, arranged to project into apertures in the faceplate B. These stops it are provided with locknuts, by preference, and they are capable of being adjusted to protrude more or less, as desired. The plate on is secured to the lugs l by means of set-screws 0,which pass through slots in said plate. This enables us to adjust the pendants m to or from plate B.

On'the faces of the bases 0 of frame G are studs p,which are engaged by forks q, mounted .on a rock-shaft, I, provided with bearings in the main frame. When this shaft is rocked back and forth the frame G is moved in and out or forward and back by reason of the engagement of the forks q with studs 12, and in its movement said frame carries with it all the parts connected thereto-namely, the bar H, punches a, nail holders or dies E, pendants m, and guide-stops a n.

In order to enable the operator to readily shift the parts, as above described, we provide the shaft I with an operating handle or lever J. (Shown in elevation in Fig. 4.) This lever is made to play between adjustable screwstops r 1, whereby the extent of movement of the parts may be carefully regulated. We usually place this lever at the right of the operator, asindicated in Figs. 1 and 4, but have shown it on the opposite side in Fig. 2, for convenience of illustration.

Figs. 2 and 3 show only half the width of the machine; but as both halves are precisely alike this illustration is sufficient. Thus, for example, in Fig. 2 only one pendant, m, provided with two stops, n n, is shown; but there are two of these pendants and four stops'in all,

I for the box while it is being nailed.

the four being arranged at the corners of a rectangle, as will be well understood.

We will now describe the operation of the machine, promising that in the drawings the cross-head is represented in its elevated or normal position and the parts set for recessing the end of a box.

K represents any suitable table or support This table may be constructed in the usual way employed in such machines.

L is the box end, and t the side,.which is in position to be nailed thereto. The box side It is pressed up to the face-plate B, which serves as a fixedor permanent stop therefor; and the box end L is pressed up against the protruding ends of the stops at a, which are capable of being moved. The stops a project in front of the face-plate B far enough to recess or set back the box end to the desired extent, as shown. The punches a and holders E are arranged to drive the nails in the middle of the box end L, as they should be driven. After these nails are driven, it the operator wishes to nail the other box end flush with the end of the side I, he simply throws over the lever J.

This not only withdraws the stops it so as to permit the box end to rest against the stopplate B, but it shifts the punches and holders correspondingly, so that the nails will be driven properly into the box end in this position. Thus, by simply throwing over lever J,'(which may be weighted at its end, as shown,) the operator is enabled to shift the parts instantly and simultaneously, with hardly an effort. The thumb-screws 0 enable the entire set of stops at to be properly adjusted at one operation. This adjustment, when once made, will only require alteration to suit box ends of different thicknesses. The set-screws r, Fig. 4, regulate the distance back from the face of B the box end is to be set. Usually this will only be aboutone-eighth of an inch; but where head-linings are to be nailed in, a greater amount of recessing will be required.

By removing the part at m with the stops it at, our improved machine may be employed for nailing large boxes with battened ends.

In making such boxes it is often desirable to drive two rows of nails-one in the edge of the batten which is flush with the box side, and one row (inside of the last named) in the box end. This may be done by simply shifting the punches and dies after one row is driven, and without shifting or moving the box. Indeed, this method may be employed in any case where two or more parallel rows of nails are to be driven without shifting the box.

Any suitable means of connecting the bar H to cross-head C may be employed so long as this bar is compelled to move vertically with the cross-head, and is yet capable of being moved to and fro horizontally independently ot' the cross-head.

Having thus described our invention, we claim-=- 1.. The combination, with the reciprocatingcross-head of a nailing-machine and the fixed stop for the box side, of a frame, G, mounted to slide to and fro in the main frame, the nailholders, and the stops for the box end, mounted on said frame G, a bar, H, arranged to slide vertically in the frame G and to engage the cross-head, the punches at, and means, substantially as described, for shifting the frame G and its accessories, substantially as and for the purposes set forth.
