GEORGE H. PERKINS,` OF PHILADELPHIA, PENNSYLVANIA.

NAILING-MACHINE.

SPECIFICATION' forming part of Letters Patent No. 240,332, dated April 19, 1881.

Application tiled June 21, 1880.

To all whom it may concern:

Beit known that I, GEORGE H. PERKINS, of Philadelphia, Pennsylvania, have invented an Improved Machine for Nailing Boxes, ot' which the following is a specification.

My invention relates in general to the class of mechanisms which are employed to automatically and continuously drive nails into material to be united; but it relates more specitically to the class of mechanisms employed to nail together wooden boxes, such as are employed in the incasing of petroleumcans and the like. It is adapted, however, to the nailing together of various kinds of material.

Of the drawings, Figure l is a central sectional side elevation of a machine embodying my invention; Fig. 2, a front elevation ofthe same; Fig. 3, a top-plan sectional view ofthe same, on the line a.' a of Fig. 1; Fig. 4, a sectional side elevation ot' a nail-holder and naildriver invented by me and forming the subject-matter of an application for patent, signed upon the same day and filed contemporaneously with this application, and denominated by lne Case A; Fig. 5, a front elevation of the saine.; Fig. 6, a top sect-ion on the line b b of Fig. 4.

In my present apparatus a reciprocating cross head operated from a driving crankshaft has connected with it a series of connectingrods,which are each secured to a wristpin connected with a separate plunger-carrier, each connecting-rod being separate from every other, and being adapted to operate its individual plunger-carrier in whatever position or inclination the latter may have been placed.

In the above construction my present apparatus diiers broadly from any previous boxnailing machine in that said `construction enables the driving of nails at angles either opposite, varying, or coincident.

In the drawings, A A are vertical standards, constituting the sides of the frame-work of the machine, and united together above in a transverse head-bar, B. Below they spread out to form a base, O, of suitable configuration to support in bearings D a driving-axle, E, operated by a driving-pulley, F, and provided with a crank, Gr, to the wrist-pin of which is secured a pitman, H, passing vertically upward to a crosshead, I, to which it is secured by a pivot-pin, J. It is obvious that the revo- (No model.)

lution ot' the axle will cause the reciprocntion ot' the cross-head.

K is a treadle in the base of the frame-work, connected with a clutch device, L, known as the Bliss clutch, ot' such familiar"construction to all mechanics as not to require explanation here. The operation ofthe clutch is to throw the driving-pulley into and out of gear alternately at the beginning and end ot' each reciprocation of the plunger, its action being regulated by the treadle.

M are ways secured to the face-plate N of the machine, in which the cross-head plays.

In front of the face-plate is the table O, upon which the box to be nailed is su pported, adapted to be raised or lowered to the proper adjustnient by means otl screw-shafts P, to which it is threaded and by which it is supported, said shafts being operated by a bevel-gear, Q, in the base 'ot' the frame-work.

R are connecting-rods, a series of which,

corresponding in number to the number ot" nail-holders, is employed. They are cach separately pivoted to the cross-head. These connecting -rods extend upward and attach to wrist-pins projecting from the plunger-carrier of each nail-holder, and are adapted to be adjusted with any lateral adjustment ot' the nailholders, or with any inclination ot' the same, so that they act invariably, upon the reciprocation of the cross-head, to operate the plungers, in whatever position the latter may have been placed.

The nail-holders represented in fourth, fifth, and sixth views of the drawings constitute the subject-matter of an application iiled by me (as Oase A) -contemporaneously with this, as hereinbetore referred to.

The separate connecting-rods B of my machine are each attached to a separate wrist-pin, f, connected with the plunger-.carriers of said nail-holders. These nail-holders consist, essentially, of a carrier-guide, within which a plunger-carrier, e, travels. The carrierguide is adapted, by means of a clamp-plate, c, or similar device, to be set at varying lateral angles upon the frame-work. Depending from the carrier-guide is the nail-holder proper, m, a tubular receptacle'incasing a pressure-spring, p, and adapted to lift upwardly and backwardly as the plunger forces the nail from it.

IOO

The nail-holder is secured to the plunger-guide in the direct line of the stroke of the plunger and assumes the same angle with the carrierguide.

Such being the construction of my invention, it is obvious that when the box is placed upon the table or bed, the machine thrown into action, and each of the plungers thereby caused to advance, the nails,one ot' which has been fed into each nail-holder, Will be driven into the material to be united, at whatever inclination the nail-holders may have been previously set, and as the machine is capable of adjustment with respect to its nail-holders, each independently of the other, it is obvious that the fastening ofthe box by varied inclination of the nails maybe made extremely' secure.

Any number ot' nail-holders may, of course, be applied, their application to the cross-bars of the machine being extremely simple, and the reciprocating cross-head being best constructed With a large number of pivots, so as to adapt it to receive a large number ot' connecting-rods.

The advantages incident to my machine are, that it enables the employment of the Bliss clutch, thus dispensing` with the use ot' other elaborate clutches, or clutches which may be uncertain in their operation; that it enables the omission ot' sectors and other kindred devices to drive the plungers, and enables the employment of a pulling mechanism which acts direct upon the plunger-carriers from the cross-bar without any intermediate mechanisms other than connecting-rods; that the action ofthe crank and pitmau in the operation of pulling down the cross-head and its series of connecting-rods attached to the nail-plungers is both simple and certain 5 and that the employment of the nail-holders enables, as heretofore stated, the angular driving` of the nails, and imparts to the machine all the advantages which are incident to the nail-holder, as described in the application for patent, which I have made for the same.

Havin g thus described my invention, I claim and desire to secure by Letters Patent of the United Statesl. In a machine for nailing boxes, the combination ot' a reciprocating cross-head, a series of independent plungers, and a series of independent connecting-rods, one'end of each of which is connected with the cross-head, and the other end of each ot which is connected with a separate plunger, substantially in the manner described,r so that the downward pull of the cross-head, acting through the separate connecting-rods, operates the plungers, substantially as described.

2. In a machine for nailing boxes, the combination of a reciprocating cross-head, operated as described, With a series of' angularly and separately adjustable plungers, by means of a series of separate connecting-rods, whereby the downward pull of the cross-head, acting through the separate connecting-rods upon the separately-adjusted plungers, causes the driving ofthe nails at angles corresponding to those at which the plungers have been disposed, substantially as shown and described.

In testimony whereof I have hereunto signed my name this 1st day of May, A. D. 1880.

GEORGE H. PERKINS.

In presence of C. B. TAYLOR, J. BoNsALL TAYLOR.
