Description
UNTTEE STATES PATENT OFFICE. A
CHARLES XV. GLIDDEN, OF LYNN, MASSACHUSETTS.
IMPRQVEMENT lN LASTlNG-TOLS.
Specification forming part of Letters Patent N0. 136,318, dated February 25, 1873.
.To all vwhom yt may concern:
Be it known that I, CHARLES W. GLIDDEN, of Lynn, in the county of Essex, and State of Massachusetts, have invented an Improved Lasting-Tool; and I do hereby declare that the following, taken in connection with the drawing which accompaniesA and forms part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.
The invention has particular reference to the arrangement of mechanism by which each tack, in turn, is separated from a row of tacks behind it, and is dropped into a vertical tube, in which tube is the driver, by the blow ot' which the tack is driven; and the invention consists, primarily, in the combination and arrangement of mechanisln for transferring' each tack, in turn, from the chute containing a row of tacks to a position over or in the drivertube and under the driver, so thatY by the blow of the driver such tack will be driven.
The drawing represents a tool embodying vthe invention.
Figure l shows the tool in side and sectional elevation. Fig. 2 shows a bottom view of it.
Fig. 3 shows the driver-tube in section, and
a denotes the vertical piston or driver tube, v
in which plays a piston, b, at the foot of which is a driver, c, which normally sta-nds over a nail-tube, d, the piston being held up normally by a suitable spring, e, and when forced dovn causing the driver to enter the nail-tube ,d and drive the tack which may be contained therein. At j the piston-tube is cut through to one side, and into the opening extend two prongs, f, ot' a tack-chute, g, (shown in top and end view at Figs. 4 and 5,) these prongs being a continuation of inclined ways t', upon and downv which the tack-heads slide, and between which the tack-Shanks pass, the tacks sliding down the chute by gravity, and the movement of the column being arrested by a slight spring which rests upon the head of the foremost tack at the end of the prongs. This chute is made removable, being attached to a long arm, k, extending from the tube a, and the ways and shank-groove are made long enough to receive a large number of tacks, the chute being preferably charged or loaded in a separate machine and then fastened to the arm k, the inclination of the chute, in connection with its construction, being such that the tacks follow down as fast as each end one is removed. The chute is shown as fastened to the arm k byI spring-latches l, but may be held by any other suitable spring or other fastenings which secure it in place and enable it to be readily removed and reattached. Just below the prongs f a fork, m, at the end of a horizontal lever, a, extends into the driver-tube. This lever turns on a pin, o, at the foot ot a vertical lever, p, fulcrumed at q. Then the lower arm. of this lever p is thrown in one prong of the fork mpasses between the shanks of the two endmost tacks of the chuteprongs f, and as the lever n reaches its inmost position an arm, fr, strikes a stop-pin, s, and swings the fork m in toward the center ot' the nail-tube, thereby removing the end tack from the prongs f to the fork m..- As the fork moves back, by the p stress of a suitable spring, t, the tack strikes the side ot' the tube, being thereby stripped from the fork, from which it falls into the tacktube. The fork is restored to its normal position by striking another stop, u, a stop, c, limiting its movement. As the driver -is forced down by a blow upon the head w of the piston it strikes the head of the tack and drives the tack into the surface beneath the tube. The lever p is operated by the plunger b. When the plunger descends it imparts no movement to the lever, but when it rises it actuates the lever and causes the fork to both enter the tube and separate the end tack from the rest of the tacks and drop it into the nail-tube. For this purpose the upper arm ot' the lever p has resting against it a pin, y, projecting from a pivoted arm, a, against which a spring bears to force the pin y against the lever-arm. The plunger b has extending through a vertical slot in` the plungertube a pin, a2, and when the plunger descends this pin presses the pin y back and moves the arm e, imparting no movement to the lever p, but when the 2 menare 2. In combination with the tnbe a and olinte g, the lever r, with its prongs n, the lever being operated to remove the tack from the chute and drop it into the tube d, substantially as described.
3. In combination with the tube a, a tackchute, g, maderemovable, substantially Aas described. Y'
CHARLES Vv'. GLIDDEN.
