SEWING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 360,095, dated March 29, 1887.
Application filed December 9, 1885. Serial No. 185,184.
(No model.) Patented in England May 5, 1885, No. 5.505; in France November 5, 1885, No. 172,034; in Belgium November 13, 1885, No. 70,812 in Germany November 13, 1885, No. 37,095, and in Anstria-Hungary January 18, 1886, No. 40,878.
To all whom, it may concern:
Be it known that I, Jol-IN HoLRoYD, a sub4 ject of the Queen of Great Britain and Ireland, residing at 41 John Dalton Street,h/Ianchester, in the county of Lancaster, Kingdom of Great Britain and Ireland, have invented new and useful Improvements in Sewing Machines, (which has been patented to me as follows: Great Britain, No. 5,505, May 5, 1885; Belgium, No. 70,842, November 13, 1855; and to my assignees Francis Thywissen and Victor Witte as follow: France, No. 17 2,084, November 5, 1885, Germany, N o. 37,095, November 13, 1885, and Austria-Hungary, No. 40,878, January 18, 1886,) of which the following is a specification.
In the accompanying drawings, Figure 1 is a side elevation of so much of a button-hole sewing-machine as is necessary to illustrate the nature of my invention. Fig. 2 is an elevation,with the side cover removcd,of the reverse side of the goose-neck or overhanging arm shown in 1, with its attached parts. Figs. 3, 4, 5, and 6 are detail views hereinafter described.
c is a block, and b is a die working in conjunction therewith for cutting the button-hole in the material operated upon, in a manner well understood. The said block c is carried by a lever, c, hinged or pivoted to the machine at c', so as to be capable of being turned down against the die, or of being thrown back out of the way when not in use.
In order that the block a may be securely held in position against the upward pressure of the die during the operation of cutting a button-hole through the material, I employ a spring-catch, cl, pivoted to the machine at e. This spring-catch d is provided with a tooth, projection, or hook-like stop, d', adapted to engage with a corresponding tooth,proj ection, or hook-like stop, c2, on the lever c, and effectually prevent the said lever and attached block a from risingduring the cutting operation.
f is a spring secured at one end to the catch 1, and at its other end to the frame of the machine, and designed to cause the catch to move forward automatically when the lever c is lowered, and to cause the teeth, projections,or 5o stops d and c2 to become interlocked,as shown.
g is a handle for moving the springcatch backward to unlock the said teeth,projections,
or stops d and c2 when it is desired to throw the block a and lever c backward or upward out of the operators way.
h is a bent spri'ng,secured at one end to the bearing t', in which the lever c turns. Itis provided at its free end with a projecting portion or detent, t, adapted to enter a recess, j, 6o in the end of the lever c and retain it automatically in its raised position when thrown back.
Then the edges of a button-hole are being bound or sewed one of the divided ends of thread is apt to interfere with the action of the needle or to get on the wrong side thereof, so as to spoil the work. To maintain a clear path for the needle,and also to keep the thread in its proper relative position, there is em- 7o ployed a finger or device pivoted horizontally beneath the base-plate or to the top or face plate of the machine, and worked by a cam on the feed-shaft, so as to oscillate at the proper intervals and carry the end vof the thread clear 7 5 of the needle and to the proper side thereof.
Fig. 8 is an under side view of the top or face plate ofthe machine with a finger 01 device for the purpose stated pivoted thereto. Fig. 4 is a side elevation of the said plate in 8o its working position, with the iinger or device, feed-shaft, cam, and attached rotating hook.
k is the finger, pivoted at It" and provided with a downwardly-projecting pin, k2, so arranged relatively to a cam, I, on the feed-shaft m as to be moved thereby in one direction at the proper intervals, movement in the opposite direction being effected by a spring, n.
o is the hook or looper.
An improved pull-off device and tension 9o arrangement are also provided, which are shown in Fig. 2, and in Figs. 5 and 6, which are transverse sections on the lines x .r and y y, respectively, of Fig. 2. In the pull-off device there is employed a finger or lever, p, situated between two standards or guides, q, across which the thread passes from the bobbin r, Fig. 1. This nger is worked or oscillated by a cam, s, on the upper shaft, t, of the machine, so as to pull a certain length of thread from the bobbin at each stroke of the needle.
u is a double tension-disk, which is caused by another cam, u, on the shaft t to nip or hold the thread that passes between the two portions or disks thereof vwhen I(he finger 19 moves to the right, as shown in dotted lines in Fig. 5. To this end the double tensiondisk is carried by a pin, u2, which is moved to the right by a bar or lever, n, actuated by the cam u', whereby the two halves of the tension-disk are forced against the frame of the machine, and the thread between them nipped or held fast.
The hereinbefore-described tension arrangement is applicable to sewing-machines other than those of the button-hole type.
What I claim isl. The combination, with a block-carrying lever pivoted above thebase-plate and having a notch in its under side, of a catchlever pivoted at its lower end beneath the base-plate,
^ its'upper end extending above said plate and carrying lever having a Ynotch in its pivoted end, of a bent spring, one end of which is secured to the bearing for the lever, the other end being provided with a detent for engaging with said notch when the lever is in an elevated position, substantially as described, and for the purpose set forth.
3. In a button-hole sewing-machine, mechanism for carrying one of the ends of the thread clear of the needle, said mechanism consisting of a finger, ask, pivoted to the faceplate and having a downwardly-projecting pin, as k2, a cam, as Z, on the feed-shaft, with which pin k2 engages to throw the finger, and a spring, as n, for returning the finger to its normal position, combined substantially as described.
4. In a sewing-machine, the combination,'
with a pull-off, of a tension device consisting of a horizontally-movable rod mounted in a standard on the goose-neck, the said4 rod carrying-at one end a double disk for nipping the thread, a lever, the upper end of which engages with. the other end of the disk-rod and the lower end of which is pivoted in the goose-neck, a cam on the upper shaft of the machine for contacting with the lever and reciprocating the disk-shaft, and a spring for pressing the lever against the cam, substantially as above set forth. t
