NAlLlNG-WIACHINE FOR BOOTS OR SHOES.
SEEGFICATION forming part of Letters Patent No. 333,812, dated January 5, 1886.
Application filed November 5, 1885. Serial No. 181,957. (No model.)
To all whom it may concern.-
Be it known that I, FRANK A. BEAL, of Haverhill, county of Essex, and State of Massachusetts, have invented an Improvement in Nailing-Machines for Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention has for its object to provide a nailing-rnachine with mechanism for uniformly feeding headed nails ortacks into a position below the driver, the headed nails being dropped singly into a nose or nail-tube below the driver, after which they are driven singly.
In my improved apparatus the driver-bar, carrying the driver, is made to reciprocate through a feeding-cylinder arranged within a tubular shellor case provided at its inner side with a spiral groove, the lower wall left by forming such groove serving as a support for the heads of the nails or tacks as they are fed from the upper end of the shell or case by means of the feeding device, preferably made as a roller grooved longitudinally.
Figure l, in side elevation, partially broken out, shows my improvement embodied in a nailing-machine adapted to be operated by hand; but I desire it to be understood that the devices herein described, with slight altera-tions, may be adapted for use in power machines. Fig. 2 is a side elevation of the feeding device alone, the upper end of the feeding device being partially broken away. Fig. 3 is an upper end View of the feeding device, together with a portion of the case or shell, the said figure showing three headed nails in the positions that they will occupy when the machine is in operation. Fig. 4E is a side elevation, chieiy to show the case or shell and its nose, a portion of both the shell and nose being broken away. Fig. 5 is a top view of Fig. 4t, and Fig. 6 is a detail of the pawl for rotating the feeding device interniittingly.
The feeding device-co1nposed, preferably, of a long cylinder, A, provided with a series of grooves, a c, extended from end to end, and a central longitudinal passage, (LC-has at its upper end a ratchet-wheel, a2. The case or shell B, made as a cylinder, is grooved spirally atb, leaving surfaces 2 2, upon which may rest the flanges of the heads of nails or tacks n. The feeding device A is placed within the case or shell B, with the lower end of the feeding device resting upon the nose C, having the driver-opening G, the lower end of the said opening receiving within it suitable nail-cen* tering springs, c, which act, as usual, to keep the point of the nail from descending too low before being struck by the driver. The upper end of the nose is provided with a flange, ci, which is screwed or otherwise attached to the lower end of the case or shell. The case or shell B receives within it the feeding device A, and is kept therein by the cap D, flanged to embrace the upper end of the case or shell, the said cap having a bearing, d, through which is extended the driver-bar E, having secured to its lower end the driver e, the spiral spring e', surrounding the driver, and in practice resting at its lower end upon the metal block constituting the nose, actingagainst a shoulder, e?, normally keeping the said driverbar in its elevated position, the lower end of the driver at such time being below the point f, (see Fig. 4,) where the hole in which the driver works intersects a diagonal passage, n, which joins the lower end of the spiral grove b with the driver-passage C. The driver-bar E has at one side a straight groove, g, which receives a pin, g', of the collar d, the said pin preventing the rotation of the driver`bar and driver as the said driver-bar is made to reciprocate in one direction by pressure or by a blow against the knob g3 or by the spring e'. The driver-bar is also provided with a second groove, aportion of which is made cam-shaped, as at h. This canrgroove receives in it a pin, h', extended through a collar, h2, surrounding the driver-bar loosely. The collar h2 has attached to it a pawl, ha, which is made to engage one and then the other tooth h4 of the feeding device. In the reciprocation of the driver-bar the action of the cani-groove h upon the pin 71. causes the collar h2 to rotate, the pawl h3 at such time engaging the teeth la* and rotating the feeding device.
Referring to Fig. l, it will be noticed that each headed nail or tack rests in a longitudinal space of the feeding-roll, and in that tig- IOO ure, as well as in Figs. l and 4, it will be noticed that the heads of the nails are supported by one of the flanges formed by the spiral groove b in the case or shell, and being so engaged and supported, substantially as shown in Fig. 3, the rotation of the feeding device enables the latter to act as a toothed surface with points between adjacent headed nails, thus positively feeding the said nails down along the said groove from the upper to the lower end of the case or shell.
I do not desire to limit my invention to the exact construction of feeding device herein shown and described, for instead of it I might employ any other usual or well-known equivalent roller which would act to keep nails separated one from another and to push or carry the individual headed nails.one after the other,
from the upper to the lower part of the annularly-.grooved case or shell, discharging the same into the nose C, to be acted upon by the driver e. When the driver is in its lowest position. it covers the mouth of the opening n3, leading from the groove b, into the driverpassage. The nails are permitted to pass from the groove n3 into the driverpassage only when the lower end of the driver is brought above the pointf.
I claim- 1. The spirally-grooved case or shell, combined with a rotating feeding device substantially such as described, to engage the headed nails supported by their flanges at the inner side of the said case or shell, as described, the feeding device effecting the gradual feeding of the headed nails from the Lipper to'the lower end of the case or shell, substantially as described.
Y2. The case or shell provided with a spiral groove, the attached nose provided with a groove for the driver, and having a groove to lead the tacks from the spiral groove into the driver-groove, and the driver-bar, and the driver, combined with the rotating feeding device, grooved substantially as described.and with a pawl to engage the ratchet-Wheel upon and rotate the said feeding device, substantially as set forth.
In testimony whereofI have signed my name to this speciiication in the presence of two subscribing witnesses.
