NEEDLE-INSERTER FOR EMBROIDERING-IVIACHINES.

SPECIFICATION forming part of Letters Patent No. 764,119, dated July 5, 1904.

Application filed October 23,1903. Serial No. 178,188. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES A. GONZEN- EACH, a citizen of the United States, residing in New York, borough of Kings, and State of New York, have invented certain new and useful Improvements in Needle-Inserters for Embroidering-Wlachines, of which the following is a specification.-

This invention relates to an improved de vice for inserting simultaneously a gang of needles into a corresponding number of grippers of the well-known Swiss and other embroidering-machines.

In the accompanying drawings, Figure l is a perspective view of my improved needleinserter for embroidering-machines. Fig. 2 is a perspective view of the guard-frame used in connection with the inserting device for separating the needle-threads after the needles are transferred to the grippers of the embroideringmachines. Fig. 3 is a vertical transverse section on line 8 3, Fig. l, drawn on a larger scale. Fig. i is a vertical longitudinal section of a portion of the needle-insorting device 'on line 4: 4, Fig. 3. Fig. 5 is a vertical transverse section on line 5 5, Fig. 6, through the needle-gripping mechanism of a Swiss embroidering-machine, showing my improved needle-inserter and guard-frame in position relatively to the grippers for transferring the threaded needles; and Fig. 6 is a plan view of Fig. 5.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents my improved device for inserting needles into the grippers of Swiss or other embroidering-machines, and B a guard-frame which is used in connection with the same. The needleinserting device A is composed of two clamping-bars a a, of sheet metal or other suitable material and preferably angular in cross-section, which are connected in such a manner that their horizontal portions are made to overlap each other, while their vertical portions are arranged parallel with each other, so as to form a hollow bar of U-shaped crosssection. The underlapping portion of the angular bar a is provided with transverse grooves (4 which are of sufi'icient size for holding the shanks of the needles used in mm broidering-machines. The overlapping portion of the angular bar a is provided at its under side with a friction layer a of elastic or flexible material, such as leather, felt, &c. When the bars are clamped together, this friction layer of one bar overlies the grooves of the other and forms in connection with said grooves aseries of sockets for the needles, one side of said sockets being composed of rigid material, which accurately guides the needles, and the other side permitting the needles to be inserted freely in their sockets and exerting a frictional pressure thereon and preventing their slipping or dropping out of the grooves. The overlapping portions of the angular bars a a are provided with registering holes at points intermediately between the grooves a for the needle-shanks, as shown in Figs. 1 and 6, and fastened together by clamping-screws d.

The guard-frame B, that is used in connection with the needle-inserting device A, is made rectangular in shape, the horizontal rods Z) being connected by vertical partition-rods b, the distancesof which from each other are equal to the distance between the needles of the embroidering-machine. The upper rod 7) of the guard-frame B is provided at its ends between the vertical rods I) with rubber sleeves e, which rest with a certain degree of friction on the grippers when the guard-frame is placed in position over the same, as shown in Figs. 5 and 6. The guard-frame B is not connect ed with the inserting device, but is placed in position over the needle-grippers in such a manner that the vertical partition-rods of the guard-frame are located midway between the grippers, as shown in Fig. 6.

Each needle-inserting device A is of suflicient length to permit the insertion of about twenty needles. Several needle-inserting devices are employed for each embroidery-machine, according to the number of needles in the same, and are filled with threaded needles by inserting them into the grooves of the inserting device while the machine is running. The needles are first threaded by the girls and then placed into the inserting device A, so

that the same is ready for use as soon as the the frictional hold of the needles in the inserting device, so that a gang of needles and their threads are thus transferred simultaneously to the grippers. The next set or gang of needles is then inserted into the adjacent set of grippers, and so on until all the grippers of the machine are provided with threaded needles.

The needle-inserting device is made of a convenient length, as many of them being used as required by the size of the em'broideringmachine and the number of needles in the same. After the threaded needles have been transferred to the grippers the guard-frame, which-has been placed before the needles are transferred in inclined position over the grippers, as shown in Fig. 5, is then moved forward away from the grippers. The needlethreads, which during the inserting of the needles have been placed over the gripperactuating eccentric, as shown in dotted lines in Fig. 5, are thereby pulled through the openings of the guard-.f-rame and separated from each other, one for each needle, and then dropped vertically below the needles, one thread being thereby separated from the other by the gradual motion of the needle-threads through the open portions of the guard-frame and dropped into position, as shown in full lines in Fig. 5.

By my improved inserting device the grippers of embroidering-machines can 'be'quickl y supplied with threaded needles at considerable saving of time and labor, the supply of threaded needles to the embroidering-machine being, furthermore, accomplished in a very convenient and satisfactory manner without delay in the unraveling of the threads and replacing the individual needles in the machine.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A needle-inserting device comprising two clamping-bars, one of said bars having transverse grooves on its inner face adapted to receive the needles, and the other bar having a friction layer on its inner face, serving to cover one side of said grooves and holding the needles therein by frictional contact therewith. v

2. A needleinserting device comprising two clamping-bars, one of said bars having transverse grooves on its inner face adapted to receive the needles, and the other bar having a friction layer on its inner face, serving to cover one side of said grooves and holding the needles therein by frictional contact therewith, and means for adjustably clamping said bars together.

3. The combination with aneedle-inserting device provided with sockets for a gang of needles, of a guard-frame providedwith partition-rods for separating the needle-threads after the needles are inserted into the grip pers, substantially as set forth.

4. The combination, with a needle-inserting device provided with sockets for receiving a gang of needles, of a guard-frame composed of longitudinal rods and transverse partitionrods, and the upper longitudinal rods being provided with elastic sleeves, substantially as set forth.

5. In needleinserting devices for embroidering-machines, a guard-frame for separating the needle-threads after the needles are inserted in the grippers, consisting of longitudinal rods and transverse partition-rods at a distance equal to the arrangei'l distance between the needles-and grippers of the embroidering-machines, substantially as set forth.

In testimony that 1 claim the foregoing as my invention 1 have signed my name in presence of two subscribing witnesses.
