IMPROVEMENT IN MACHINES FOR NAILING BOXES.

Specification forming part of Letters Patent No. 155,284, dated September 22, 1874 application filed July 20, 1874.

To all whom it may concern:

Be it known that I, MATHEW BLASER, of Detroit, in the county of Wayne and State of Michigan, have invented an Improved Machine for Nailing Boxes, of which the following is a specification:

The nature of my invention relates to an improvement in that class of machines which are used for nailing together the sides and ends of cigar-boxes and other tight packages, wherein three or more nails can be driven by a single movement of a treadle'; and it consists in the peculiar construction of the machine, and in the adjustability of the devices which adapt it to the nailing together of the parts of boxes of various sizes, as more fully hereinafter set forth.

Figure l is a perspective view. Fig. 2 is a cross-section of the table at a: a. Fig. 3 is a longitudinal vertical section at 3 y.

In the drawing, A represents a suitable frame, which supports a table, B, across the rear end of which I- journal a rock-shaft, 0, having a long arm, D, and a shorter one, D. To the former is pivoted a connecting-rod, E, whose lower end is pivoted to a treadle-lever, F. To the short arm D is pivoted a link, G, having an eye in its front end, which is pivoted between the jaws of a sliding hammer, H, by a long transverse pin,.I, to which two other hammers, H, are pivoted, one at each side of the hammer H, by sliding the eye of each upon said pin.

The hammer H slides in a long box-like bearing, J, secured to the table, while the side hammers slide in boxes J, secured to plates K, which are laterally adjustable in recesses cut in the table-top, being secured at any point by a set-screw, a, passing through a slot, b, in each plate K. As the hammerboxes are adjusted to or from the central one, so the hammers H are adjustable on the pin I. The hammers are retracted by a spring, L, or its equivalent, until their striking-faces are flush with the ends of their bearin gs, except the lower part of each, which is extended like a trough to form a receptacle, 0, the length of the nail, brad, or tack used.

M is a rest on the front end of the table. parallel with the ends of the hammers. It is adjustable to receive box sides of varying widths between it and the hammer.

In the present instance I effect such adjustment by making a parallel lower part, M, to slide in dovetail ways N under the table. The part M is longitudinally slotted t0 straddle a nut, O, pendent from the table, through which is tapped a screw, P, passing through the head of the said rest; but it is evident that the said rest can be adjusted in a variety of ways.

Fig. 3 shows the operation of the hammers in driving the nails.

The rest M is adjusted to receive the bottom and a side of a box, or any other two parts to be nailed, between it and the nail receptacle 0, in each of which a nail has previously been placed. A downward movement of the treadle throws forward the hammers, which drive the nails home.

The hammers being laterally adjustable, the nails can be driven into the material at any desired distance apart.

What I claim as my invention, and desire to secure by Letters Patent, is

In a single box-nailing machine, the combination of a suitable frame, A, and platform B with a treadle, F, and rock-shaft (l, which control, by intervening rods, the horizontallysliding hammers H and H, said hammers sliding in lipped boxesJ and J, of which the latter are laterally adjustable by means of the adjustable plates K,t0 which they are secured, and the rest M, also adjustable by means of a stud, O, and screw 1?, the several parts being constructed and arranged substantially as described, and for the purposes set forth.
