BOX-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 549,348, dated November 5, 1895.

Application filed April 28, 1894:.

To all whom t may concern:

Beit known that I, WILLIAM S. Doro, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Box Nailing Machines, of which the following is a specification.

This invention relates more particularly to attachments to an ordinary box-nailing machine whereby the hoopsand staves of a substantially-conical packing-basket, such as a peachfbasket, may be nailed by the machine.

I will describe a machine embodying my invention,and then point out the novel features in the appended claims.

In the accompanying drawings, Figure l is a partial elevation and partial vertical section of a box-nailing machine embodying my invention. Fig. 2 is 'a front elevation thereof. Fig. 3 is a plan view of the invention detached from the main portion of the machine. Fig. 4 is a partial section and partial elevation thereof. Fig. 5 is a sectional view,on an enlarged scale, of a carrier employed and its operating mechanism; and Fig. 6 is an elevation of a basket-support employed. Fig. 7 is an enlarged View of the punch.

Referring by letter to the drawings, A designates a standard of a box-nailing machine; A', a vertically-reciprocating cross-head carrying the punches a. A2 is the driving mechanism for the cross-head and punches. A3 is the nail-pan, and A4 shows the nail-chutes.

The parts above mentioned are similar in all respects to the machine shown and described in my Patent No. 192, 086,0f February 21, 1893, and need no further description here.

I will now describe my present invention as attached to the machine. As all the nailpunches operate in substantially the same horizontal planes,it is necessary that the part of a peach-basket directly under the punches and in which the nails are about to be inserted should be supported rigidly in a horizontal plane.

B designates a hub extended inward and inclined upward. This hub is mounted on and has a swinging movement on a stud b, extended upward from a standard B', mounted on the table B2 of the box-nailing machine. The hub has a flange portion b,provided with Serial No. 509,288. (No model.)

an arc-shaped slot b2,into which a pin b3 on the standard B' extends. The end walls of the slot b2 by striking against the pin b2 will limit the swinging movement of the hub B.

C is a carrier loosely mounted on the hub B. This carrier is shown as annular or oircular in form,and it has on its outer surface an annular row of ratchet-teeth c,correspond ing in number to the number of nails to be driven in a row around a basket.

C is a ring rotarily mounted on a sleevelike projection of the carrier C. This ring carries a longitudinally-movable dog or pin c. The pin is inserted in a socket formed in the ring, and is forced outward against the ratchetteeth by means of a spring c2, as plainly shown in Fig. 5. An arm C2 extends from a ring C, and a link C2 has a detachable pivotal connection at its lower end with said arm and at the upper end a fixed pivotal connection with a pin on the cross-head A by means of a bolt and nut.

D indicates a basket-support vremovably mounted on the carrier C. The support is made of suitable metal and is conical to conform to the shape of a basket to be supported during the nailing operation.' To prevent a rotary movement of the support relativelv to the carrier, I provide a stop, here shown as consisting of a pin c2, on the carrier C, adapted to extend into a hole cit in theend wall of the support. At its Opposite or small end wall the support D has a journal D extended from it, adapted to rotate in a yoke or open top bearing D2 in an arm d, which has a pivotal connection with a standard et, mounted on the table B2. The arm d has an outward and inward swinging motion, so that the bearing D2 may be connected with or disengaged from the journal D. It is designed that the arm d may be moved easily on its pivot d2, when desired, but at the same time have sufiicient tension to prevent its accidental movement. To provide this tension, I extend the pivot-pin d2 outward through the lugs of the standard d and surround said extended portions with springs cl3, which have one end secured to the standard and the other end attached to the pin or collars thereon, as indicated in Fig. 3.

It is desirable to have a retarding device for the basket-support to prevent a too easy IOO All

movement thereof in its rotation. The retarding device here shown consists of a metal band E, which may be resilient, engaging friction-tight around the periphery of the carrier C and having a projection on its jointed ends e, extended to engage against a iixed portion of the machine-for instance, against the table B2.

As the basket material is apt to be split by the nails if the same are driven in too abruptly, l obviate this danger by providing means for a longitudinal yielding of the nailpunches. The means here shown consists of a rubber cushion E, arranged between the upper end or head of each punch and a portion of the punch-supporting bar E2, carried by the cross-head A. The bar E2 is connected to the cross-head A by means of arms e', which are sufficiently long to bring the nail-punches in line with the highest part of a basket. The punches are adjustable longitudinally of the bar E2, so as to accommodate them to different lengths of baskets. To provide for this adjustment, the bar E2 has a longitudinal groove f formed in it, and the head portions F of the punches have tongues f to engage in this slot. The cushions E may serve to hold the punches in their adjusted position. The nail-pockets Fl are also adjustable longitudinally of a bar G, supported from the standards A. The pockets F' have rearward extensions g, which rest upon the upper surface of the bar G, and

bolts g', having their heads engaged in an inverted-T-shaped longitudinal slot in the bar G, extend through holes in the portions g, and at their outer ends the bolts are provided with tightening-nuts g2.

The operation of the device is as follows: To place a basket on the support D or to remove it therefrom, the yoke-bearing D2 is removed from the journal D and the parts swung outward, as shown in Fig. 3. Vhen it is desired to nail a basket which has been previously formed of sta-ves and hoops in the usual manner, it isA placed on the support, which is then swunginto position, as shown in Fig. 2, with a stave and the hoops beneath the nail-punches. n the downward movement of the cross-head the punches will force the nails through the material of the basket and the ends will be turned or clinched by contacting with the metal support. During this operation there will be no movement of the support and basket, as the dog or pin c will be moved against the inclined surfaces of the ratchet-teeth c; but upon the upward movement of the cross-head the dog or pin will engage against the shoulder of a tooth and rotate the carrier C and consequently the support D one step to bring the next stave of a basket under the punches.

Having described my invention, what l claim isl. The combination witha box-nailing` machine, of a basket support, a carrier therefor, ratchet teeth on said carrier, a swinging` hub upon which said carrier is mounted, a spring impelled dog or pin engaging with the ratchet teeth and means having connection with the cross-head of the machine for operating said dog, substantially as specified.

2. In a box nailing machine, the combination with driving mechanism, of a rotary support, a carrier therefor, a pin c3 on the carrier engaging in a hole in the support for pre venting a relative movement between the support and carrier, a tensioned swinging bearing for one end of the support and a retarding device for the support, substantially as specified.

Signed at Brooklyn, in the county of Kings and State of New York, this th day of April, A. D. 1894.

VILLIAM S. DOIG.
