IMPROVEMENT lNfMAl-HNES FOR FlinS mattestsnaetaiispg' 1J iris-n STATEs Specification forming part of Letters Patent No. 174,603, dated March 7, 1876; application filed March 8, 1873.
To all whom it may concern:
Be it known that I, HARRY A. WILLS, of Chicago, in the county of Cook and State of Illinois,'have invented a new and Improved Machine for Beveling and Trimming the Points of Horseshoe-Nails, of which the followingis a specification:
The invention consists in the improvement of machines for finishing horseshoe-nails, as hereinafter described, and pointed out in the claims.
Figure l is a plan view of my improved machine, with a part of the stationary guiderim in horizontal section. Fig. 2 is a horizontal section, taken on the line a: w of Fig. 1. Fig. 3 is a vertical section, taken on the line 3 y of Fig. 2, the parts represented being those seen when looking in the direction indicated by arrow a; and Fig. 4 is a vertical section on the line 2 z, the view being taken in the direction indicated by arrow 1).
Similar letters of reference indicate corresponding parts.
A is the stationary beveliug-dic, 'B the stationary trimming-die, U the movable bevelingdie, and D the movable trimming-die, which are such as are used in other machines of this kind, both the movable diesbeing arranged on a movable block, E, which is worked by a crank-shaft, F. To' feed the nails to these dies, I now propose to have a large circular carrier rim, G, arranged in a stationary ground support and guide, H, so as to turn in it and run past the stationary dies A B, as shown in the drawings, and having notches I for carrying the nails, the said notches being cut into the face, so as to carry the nails vertically and hold them in front of the dies while the rim is at rest, the said notches being the same distance apart that the stationary dies are, and deeper than the thickness of the nail-shanks, so that they will present the nails in front of the projecting beveling-die, and present one to each die to be acted on simultaneously. The upper and lower flanges K of the support H keep the nails up to the bottom of the notches until they are brought to the trimming-die, where the saidsupport has an opening through it to allow the nails to be pushed out through the stationary trimming-die. Over the stationary beveling-die is a spring-presser, L, which bears on the heads of the nails to hold them down firmly while the points are acted on by the bevelingdies to prevent them from being forced up thereby, and there is a similar presser over the stationary trimming-die. These pressers are mounted on the vibrating-bar M, pivoted in stationary bearings N, and having a spring, I
O, for lifting the pressers to allow the nail heads to pass under them. The pressers are forced down by the elevation P on the movable die-stock, which is forced under the end Q of bar M each time the movable dies go forward, just after the nails have been presented under them, and before the movable dies come to the nails. When the die-stock goes back, the elevation P withdrawsfrom under the bar M, and allows the spring 0 to throw the pressers up.
The carrier-wheel is turned by the pullingpawl R, which is actuated by the lever S, wheel T, and cam U in the direction for turning the carrier, and it is thrown back by the spring W. The said pawl engages the carrier in the notches I, in which the nails are carried, the nails being put in after the notches pass the pawls, and therefore moves it each time just thedistance from the beveling-die to the trimming-die, and it is arranged so as to stop the carrier with the nails exactly in front of the dies. A pawl, X, for holding the carrier against back-motion is used, the said pawl also engaging it in the notches. These pawls are caused to drop into the notches by springs Y, and they are forced out by the rim itself acting on the inclined sides of the hooksthat is to say, when the pulling-pawl is pushed back, its inclined side is thereby forced against the wall of the notch, which forces it up out of the notch, and when said pawl pulls the rim forward, the wall of the notch in which the holding-pawl is located bears against the inclined side of the pawl, and forces it out.
This pawl is mainly to hold the rim against back-motion, the pushing-pawl being relied on to hold it against going forward while the dies are working.
This allows of the pawls being so shaped flanges K K, and the beveling and trimming that they can be forced out by the rim, as the dies. sides, which are beveled for that purpose, are 2. The combination of the head-presser L, not required to be shaped so as to prevent it. spring 0, oscillating bar M, and the elevation Having thus described my invention, 1 P on the movable die-stock, substantially as claim as new and desire to secure by Letters specified.
