GLOVE AND FUR SEWING MACHINE.

SPEGIFICATION foI-ming part of Letters Patent No. 288,949, dated November 20, 1883,

Application filed July 9, 1883 (No model.)

To ail whom it may concern.-

Be it known that I, W ALDEMAR Li mncn,

of Hob ok en, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements in Glove and Fur Sewing Machines,oli' which the following is aspecification.

This invention relates to overseam sewing machines of that class in which a reciprocat- IO ing needle, an oscillating looper, and two rcvolving feed-disks are employed to feed and stitch gloves, furs, and other articles. In the machines of this class it has been customary to support the outer feed-disk by means of a I 5 hanging arm, which extends upward from the said. disk and thence toward and through the casing of the machine, so as to afford below the disk an open space for the passage of the work as it is moved forward by the two feed-disks; but when the machines have been designed for sewing smaller articles-such as gloves or short furssaid space below the disks is not required, and the outer feed-disk has then been supported by other means-as, for example, on the upper end of an upright shaft that extends downward and passes through the base of the machine. For the purposes mentioned two separate machines have been employed heretofore.

The object of my invention is to provide a machine which may be advantageously employed for sewing small articles, and which may be made equally applicable for sewing larger articles requiring an ample space for the passage of the work below the feeddisks.

To this end I employ an arm or bracket of novel construction for carrying the outer feeddisk; and my invention consists in the combination, with the inner and outer feed-disks, o reciprocating needle, and Oscillating looper, of a curved arm or bracket that supports a bearing for the outer feed-disk, that is supported at its lower end, vertically below the bearing of the feed-disk,in asocket or bearing 5 at the end of a fulcrumed and spring-pressed arm connected to a treadle, so that the arm and bracket may be swung in its bearing into a position sidewise of the outer feed-disk, so as to adapt the machine for sewing short work, or back of the inner feed-disk, so as to proglove and fur sewing machine.

vide an open space for the passage of larger articles to be sewed.

Inthe accompanying drawi11gs,Figure 1 represents a side elevation, and Fig. 2 a plan, of

my improved glove and fur sewing machine.

Similar letters of reference indicate corresponding parts.

A in the drawings represents the supporting-casing, and A the base, of my improved The casing A incloses the actuating mechanism of the reciprocating needle and of the oscillating looper or other stitch-forming device, while the mechanism for operating the inner feed disk, B, is arranged below the base plate A. This mechanism may be the same as that shown and described in Letters Patent No. 273,506, dated April 10, 1888, granted to me heretofore, and is not here shown, as it forms no part of the present invention. The inner feeddisk, B, is supported in bearings of a bracketplate, B, which is attached to the end wall of the casing A, while the vertical shaft of the same turns in bearings at the under side of the base-plate A. The outer feed-disk, B, 7 5 is supported in bearings at the end of a curved arm or bracket, 0, which extends first up= ward and then downward toward the baseplate, then horizontally in a sidewise direction to a point vertically below the axis of the outer feed-disk, B, then vertically downward through the base A, the lower end, a, forming a journal, which is supported in a socket or bearing,

0, at the end of a fulcrumed and springpressed lever, D, that is connected by a rod or 8 5 otherwise to a treadle, by means of which the lever can be raised, and thereby the supporting-arm G oscillated and the outer feed-disk,

B, moved away from and out of contact with the inner feed-disk, B. A spiral spring, D, 0 that is interposed between the casing A and the fulcrumed lever D, serves to press the longer arm of the lever D downward, and moves thereby the arm 0, so that the milled circumference of the feed-disk B is pressed tightly 5 against the circumference of the feed-disk B. The fabric that is introduced between the disks is thereby held firmly in position for the action 'of the needle. The supporting-arm O can be swung in the socket O, at the end of IO?) the fulcrumed lever D, around the vertical axis of the socket and the outer feeddisk, B, into a position sidewise o'f the outer fecd-disk, B, or into any radial position thereto, as shown in Figs. 1 and 2, or into aposition back of the inner feed-disk, as shown in dotted lines in the same figures. After adjustment the bracket-arm G is rigidly clamped to the socket G by the set-screw d. In one case the machine is adapted to sew gloves and smaller articles, which can be readily introduced in the space between the vertical shaft of the inner feed-disk and the portion of the arm 0 which is out of line with the feed-disk bearing and journal a, while in the other case the machine can be used for sewing furs and other larger articles, in. which the open space below the outer feed-disk must be entirely free for the handling of said articles. In this manner one and the same machine can be used for sewing different materials and articles, whereby the application of the machine is extended and the use of several machines for different purposes dispensed with.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a glove-sewing machine, the combination, with the revolving feed-disks, a horizontally-reciprocating needle, and an oscillating looper, of a curved arm or bracket which carries the outer feed-disk, and is supported at its lowerend, below the base of the machine,

in a socket or bearing of a fulcrumed and looper, of a curved arm or bracket which comprises a bearing forthe outer feed-disk, and a journal vertically below and in line with the axis of the outer feed-disk, and which is supported in a socket of a fulorumed and springpressed lever, so that the arm or bracket can be swung horizontally, to adapt the machine for large or small work, substantially as and for the purpose described. v

3. The combination of the feeddisks B and B, a curved arm or bracket, 0, supporting the outer feed-disk, B, and having a journal, a, at its lower end, vertically below said feed-disk, a fulcrumed lever, D, having a socket or bearing, 0, for the journal at, and means for securing said bracket-arm into position after it has been swung into the required position for use, substantially as and for the purpose herein described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
