GPECIFTCATION forming part of Letters Patent No. 301,464, dated July 1, 1884.
Application filed April 21, 1384. (X model.)
To (055 whom it may concern:
Be it known that we, Ennsrhs 'Woonwnnn,
of Somerville, in the county of Middlesex, and
. Henson Wnnns, of Boston, in the county of Suffolk, both in the State of Massachusetts,
citizens of the United States, have invented a new and useful Improvement in Nail-Holders,
of which the followingis a full, clear, and exact description, reference being had to the ac- IO companying drawings, forming a part of this specification in explaining its nature, in which- Figure l is a front elevation of a nailingmachine containing our invention. Fig. 2 is a side elevation thereof at the right of the front. Figs. 3 and 4 are detail views hereina'fter especially referred to. Fig. 5 is a View in elevation of the left side of' the machine. Fig. 6 is a horizontal section upon theline .9003
Figs. 3" and 7 are detail views, further illustrating the construction of the machine.
The invention relates especially to mechanism for varying the length of the nail, which is also adapted to be operated while the machine is in motion, and it is an improvement upon that described in Letters Patent No. 241,550. In said patent there is described a wire feeding mechanism, which consists of 0 two feed-rolls adapted to be moved automatically into and out of contact with each other at given intervals by a cam and suitable connecting devices, and by varying the size of the working-surface of this cam the duration 5 of, time in which the rolls are in contact can be varied so that a greater or less length of wire is fed. This cam, however, is somewhat expensive to make and does not permit of the very finest adjustments, and cannot readily 40 be adjusted to vary the length of time of feeding while the machine is in operation. In this invention wehave succeeded in obtaining a construction which is cheaper than that described in said patent, and which readily per mits adjustment while the machine is in 0poration.
Referring to the drawings, a is the nozzle of the nailingmachine. his the drive-bar. c is the cam for lifting the drive-bar in opposition go-to the driving-spring c. f is the reel; f, the
' wire. f is a nail cutting and transferring plate, which severs the nail from the end of the wire and feeds it into position to be driven. All these parts, with the exception of the reel, are fully described in said patent and Patent No. 225,527.
A is a feed-roll positively revolved in sta tionary bearings, as described in said Patent No. 225,527. It has a spur-gear, a.
A is a feed-roll supported by the spring- 6O arm B, and free to revolve thereon, and having a movement to and from the feed-roll A.
It also has a spur-gear, a which meshes with the spurgear a. This arm B hasat its lower end the inward projection or extension I), 6 which bears the relation to the projection 0' upon the arm 0 hereinafter described. This arm 0 has an oscillating movement of uniform length given it by means of the cam c" on the main shaft, the yoke 0*, and connecting-rod c and it is secured to the frame-work of the machine by the long pivot c. The arm 0 is also movable in a horizontal direction by means of the lever c which has a handle, 0 and is pivoted at c. The handle is locked in place 7 5 by means of the bolt 0 which passes through the slot o on the curved arm c" and not 0". An arm, 0, attached to this nut, permits the same to be turned and the handle to be moved and locked in any new position. The upper 8 surface of the arm 0 has a scale, to indicate where to set the handle for feeding the various lengths of wire.
From what has been said it will be seen that the block 0 has two movements in relation to g 5 the projection b on the spring-arm B: First, it has an oscillating movement which vibrates the arm B, and moves the feed-roll A out or away from the feed-roll A, the spring-arm B returning it; and, second, it has a sidewise 9O movement. The first or oscillating movement is an automatic movement, and is continuous during the operation of the machine. The sidewise movement or horizontal movement is regulated by means of the handle c". It will also be seen that while the two faces of the blocks 0' b are in contact, the roll A is held away from the roll A, and there is consequently no feeding of the wire; but after the face of the block 0 has cleared the face of the block 1) upon the upward movement of the oscillating arm 0, the roll A is permitted by the force of the spring to be moved against the roll A with force sufficient to grasp and feed the wire, and of course this feed will continue so long as the faces of the blocks 12 c are not in contact. Consequently when the face of the block 0' is narrow it clears the face of the block b sooner, and consequently the roll A is brought into operative position sooner than when the face of the block is wider, and there is a longer travel of the face of the block 0 upon the face of the block 1) before the block 0 clears the block b, and permits the roll A to be moved into operative position. It will also be seen that by making the face of the block b tapering upon its under surface, so that oneend' shall be quite narrow and the other end shall be quite broad, and there is a regular taper from one end to the other, if said block be moved in relation to the block I), the length of time which the face of block b is in contact with the face of block 0 may be indefinitely varied, and that any length of wire, from a very short to a very long piece, can be cut simply by moving this block 0 horizontally, so that the desired section shall be brought in line withthe block b. The face of the block b is the surface indicated by b and the face of the block 0 is indicated by d The block 1) projects from the arm B, so that its.
upper edge, b", shall close or move by the pro jecting portion of the block 0 when the edge d" of the said block shall come in line with said edge I), and upon the reverse movement of the v block 0 its edge d will come in contact with the edge b and will ride upon the same and throw out the lever, so that the face of the block b shall be brought against the face of the block 0. In Fig. 3 we show the two faces d I)" in contact, and in Fig.8" we show the block 0 moved away from the block b. The block 0" is secured to the oscillating arm 0 by means of a screw or bolt, d; and by means of the slot (7. in the arm projecting down from the block the block can be adjusted vertically in relation to said oscillating arm 0. By means of the lever c the block 0 can be moved while the machine is running.
The advantages of this invention are apparent from the foregoing description.
If desired,the lever c or arm 0 can be moved by a treadle and connecting-lever.
Having thus fully described our invention, we claim and desire to secure by Letters Patent of the United States- 1. In a nailing-machine, the combination of the feed-roll A, the feed-roll A, its arm B,hav-
ing the block b, shaped substantially as described, and the oscillating block 0, also shaped substantially as described, all substantially as and for the purposes set forth.
2. The combination of the feed-roll A, feedroll A, arm B,the block b, and block 0', shaped as specified, its arm 0, cam 0 and connecting devices, all substantially as and for the purposes described.
3. The combination, in a nailing-machine,of the feed-roll A, feed-roll A, the arm B, block b, and oscillating block a, shaped as specified, the handle 0 and connecting mechanism for moving the same horizontally, all substantially as and for the purposes described.
4. In a nailing-machine,as a means of varying the movement of an arm operating a por tion of the feeding mechanism, the block b, at-
tached to said arm, and the oscillating block a, shaped as specified, and adapted to have a horizontal movement imparted to it, all sub stantially as and for the purposes described.
5. The combination of the block 0, having the slot d in its downward-extending portion, with the supporting-block O and screw or bolt d, all substantially as and for the purposes described.
6. The combination, in a nailing-machine,of the feed-arm B, the block b, shaped as described, the oscillating blocl; c, shaped as specified, and adapted to have a horizontal movement provided it, the lever 0 the arm 0 and means for locking the lever to said arm,
all substantially as and for the purposes set forth.
7. The combination of the oscillating feedregulating block 0, the lever 0 and the arm 0", bearing a scale adapted to be used in connection with the handle, and indicating the varying lengths of the feed, all substantially as and for the purposes described.
