LATHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 593,864, dated November 16, 1897. I Application filed November 5, 1895. $eria1No. 568,045. (No model.)

To all whom it may concern:

Be it known that I,.IOHN G. STAUDENMAYER, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lathin g Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in lathing-machines;

and it has for its object, among others, to provide a simple, cheap, durable, and portable device which can be readily attached to suit the circumstances to which it is desired to employ it and by which the nails may be readily driven. I also provide a cutting attachment whereby the lath may be sawed any desired length.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a side elevation of my improved apparatus. Fig. 2 is a view looking at the opposite side. Fig. 3 is an enlarged sectional detail of the nail feeding and driving apparatus. Fig. 4 is a detail view of the same in plan. Fig. 5 is a perspective view of the claws removed. Fig. 6 is a perspective view showing the apparatus set up in position for use and clamped between the floor and ceiling.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawin gs by letter, A designates the base of the machine, from which rises the vertical standard A, to the upper end of whichis secured the horizontal guide-bar A. The machine may be supported in the desired position and there held by set-screws a and braced vertically by the vertically-adjustable brace A having a T-head adapted to engage the ceiling-joist or other suitable means.

B is a foot-lever pivotally mounted at one end, as at b, and its other end has pivotally connected therewith the rod B, to the upper end of which is connected one end of a spring B the other end of which is detachably engaged with a hook b, depending from the horizontal guide rod or bar.

O and O are vertically-disposed toothed rods or rack-bars mounted for movement in suitable guides,'as shown. The lower ends of these racks have pins playing in the vertically-slotted uprights of the frame A and in slots disposed longitudinally of the treadle B, as shown best in Fig. 1.

D is the striking-hammer, pivotally mounted, as at d, on the horizontal arm E, which embraces the standard and is adapted to slide vertically thereon. Carried by this horizontal arm is a nail run or carrier F.

f is a nail-regulator which, being arranged as shown best in Figs. 1, 3, and 4, serves to govern the movement of the nails and to keep them straight, so that they shall be presented properly to the shank and hooks of the hammer. This carrier or run extends over the funnel G, and the slot therein terminates at a point in line with said funnel, which latter is arranged in position to receive the falling nail from said run or carrier, thelower end of the slot of which is enlarged, as seen in Fig. 4, to permit of the ready passage of the nail when it reaches such point. This funnel has its lower end extending down to the claws g, which are adapted to hold the nails firm until they are acted upon by the nail set or pusher. The lower claw is held upward by means of springs g. (Seen best in Fig. 3.) The lever and pins indicated in Fig. 4 form a picker mechanism for letting one nail at a time drop. Mounted on this arm E is also the nail set or pusher H, mounted to reciprocate in suitable guides on said arm and retracted against the action of the hammer by a spring h. (Seen best in Fig. 1.) This nail-regulator serves to govern the movements of the nails and to keep them straight, so that they shall be presented properly to the finger and hooks of the hammer.

At the lower end of the machine is shown a horizontally-projecting arm I, having a series of openings which provide for the regulation of the spaces.

J is the lath-holder, pivotally mounted on the outer end of the arm E. J is thespacer,

also carried by the said arm, as seen best in Fig. 2. This latter is regulated by means of the slotted arms jj and the spring j as seen in Fig. 2.

K is the nail-box or nail-reservoir, arranged above the nail-run or nail-carrier, and from which box the nails feed automatically into the carrier.

L is a pivoted stop or pawl adapted to engage the rack-bar X, which is disposed between and at right angles to the rack-bars O 0', thus holding the arm in its adjusted position. Pawl L is mounted upon the arm E. Upon the rack-bar C is mounted a saw M, which may be employed for sawing off the laths when necessary. The other rack-bar G serves to actuate the hammer and also to reciprocate the saw by which laths may be out off when desired.

In operation the arm E will rise inch by inch the distance between the laths at each upward motion of the foot-lever, and when it reaches the top it can be quickly dropped by disengaging the pawl from the rack-bar O. The lath is firmly held by the lath-holders until the nail is driven. After a nail has been driven by the hammer the nail set or pusher is retracted by its spring and another nail falls into the jaws from the funnel in position to be driven by the next upward movement of the nail set or pusher. The apparatus can be readily adjusted to accommodate itself to the varying distances between the studding and can be used upon a scaffold as well as upon a floor.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

\Vhat- I claim as new is 1. In combination with a base and upright, of the horizontal arm mounted to slide on said upright, the nail feeding and driving mechanism, mounted on said arm, the vertically-movable rack-bars and a pivoted footlever connected with said rack-bars, substantially as described.

2. The combination with a base and upright of a horizontal arm mounted to slide on said upright, a nail feeding and driving mechanism mounted on said arm, the vertically-movable rack-bars and a pivoted foot-lever connected with said rack-bars and a retractingspring connected with said foot-lever, substantially as described.

3. The combination with the base and the upright, the rack-bars, the pivoted foot-lever connected therewith and a spring connected with said foot-lever, of a pivoted hammer on said arm and a nail feeding, guiding, holding and driving mechanism mounted on said arm, substantially as described.

4:. The combination with the base and the upright, the rack-bars, the pivoted foot-lever connected therewith and a spring connected with said foot-lever of a pivoted hammer on said arm, a nail feeding, guiding, holding and driving mechanism mounted on said arm and a lath-holding mechanism also mounted on said arm, substantially as described.

5. The combination with the base and the upright, the rack-bars, the pivoted foot-lever connected therewith and a spring connected with said foot-lever, of a pivoted hammer on said arm, a nail feeding, guiding, holding and driving mechanism mounted on said arm and a lath-holding mechanism also mounted on said arm and means for adjusting the latter, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JOHN G. STAUDENMAYER.
