ADJUSTABLE cums PLATE FOR FUR MACHINES Filed March 27, 1961 JNVENTOR PAUL MlSOV E ATTORNEY United States Patent 3,099,235 ADJUSTABLE GUIDE PLATE FOR IF UR MACHENES Paul Misove, 9 Lincoln Road, Great Neck, NDY. Filed Mar. 27, 1961, Ser. No. 98,367 2 Claims. ((Jl. 1l22t)) This invention relates generally to sewing machines of the type known as over-seaming machines for stitching furs, and relates more particularly to an improved attachment for supporting the furs to be stitched in proper position .with respect to the stitching head while the furs are being fed through the machine.

In such a machine it is the usual practice to support and feed the furs to be stitched through the machine in substantially a vertical plane by means of a pair of discs or wheels, one of which is rotatable. Ordinarily, however, it is difficult in practice to so guide the furs that the stitching and seaming is not spoiled in appearance.

Another objectionable feature of the seaming operation as ordinarily performed is that the seam it produces is uniformly too heavy due primarily to the fact that the needle of the machine passes through the furs at a point too far removed from the edge thereof.

Still another objectionable feature is the difliculty encountered during the seaming and stitching operation in maintaining the furs in proper position such that the edges thereof which are to be oversearned lie constantly in the same horizontal plane, the tendency being for the furs to drop as they are fed through the machine with the result that the needle either passes too close to the edges of the furs or else passes entirely over the edges of the furs, thus spoiling the seam.

It is among the general objects of this invention to obviate and avoid the foregoing objectionable features and difficulties of manufacture by the provision of cooperating parts which are operative to maintain the furs in proper stitching position as they are being fed through the machine, these parts being relatively so arranged that the resultant seam is uniformly neat in appearance and substantially flat. A specific object of the invention is the provision of a horizontally disposed pressure member arranged for slidable movement in the needle guide, which member cooperates with the stitch finger member to maintain the furs in proper stitching position.

Another object is to provide an attachment for the guide plate that serves to guide the edge of the fur ma terial and to prevent irregular stitching in over-seaming.

A further object is to provide an attachment of this kind that is adjustable for adjusting the depth of the stitch from the edges of the furs.

It is also an object of the invention to provide an attachment of this kind for a sewing machine that is easily installed on a machine, is simple in construction and economical to manufacture and is highly efiicient for the purposes intended.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 7 is a side view of the attachment on a smaller scale.

FIG. 8 is a cross-sectional view taken on the line 88 of FIG. 2.

Referring now in detail to the drawings, in FIG. 1 there is shown a portion of a conventional fur sewing machine including idler and feed discs or wheels 10 and 12, respectively, mounted on base 14. The discs or wheels have cooperating peripheral surfaces between which the skins to be stitched or seamed are clamped and fed through the machine in substantially a vertical plane, the upper edges of the skins extending a slight distance above the top plane of the feed discs or wheels.

The threaded needle 16 of the machine is carried by the needle bar 18, this bar being mounted for horizontal reciprocable movement such that the needle is caused to move back and forth across the common tangential plane and above the upper edges of the wheels 10* and 12, with the result that the needle will be caused to penetrate the edges of the skins extending above the feed wheels. Cooperating :with the needle 16 in the usual manner is a looper 20. The needle and looper are actuated by suitable mechanism in housing 22.

In accordance with the present invention, a guide plate assembly 24 is positioned on top of the idler disc or wheel 10 and comprises a main bottom plate portion 26 and an auxiliary top plate portion 28. The main plate portion 26 has an elongated rectangular-shaped body 30 with a central longitudinal groove 32 extending along the top surface thereof for intermittently receiving the point of the needle 16 as it passes through the skins. The bottom surface of the main plate portion at one end is enlarged as indicated at 34. At the opposite end the bottom surface is cut away forming an arcuate shoulder 38, said cutaway portion providing a clearance for the rim of the disc 12. Groove 3 2. intersects the remainder of the material of said opposite end. The top surface of the main plate portion 26 is flat and smooth to receive and support the auxiliary top plate portion 23. A threaded hole 40 is formed in the enlarged end of the main plate portion 26.

The top plate portion 28 has a short fiat rectangularshaped body with one end rounded and the other end straight. The body is approximately one-half the length of the body of the main plate portion 26. The body of plate port-ion 28 seats on the top surface of the rounded end of main plate body 26 with its rounded end edge registering with the rounded end edge of the plate 26. The straight end of the body of plate portion 2-8 is formed with a groove 46 aligned with and forming an extension of the groove 32 in main plate portion 26. A smooth-walled hole 48 is formed in the body in alignment with the groove 46, which hole 48 is in register with the hole 40 in the main plate portion 26 for receiving a headed and threaded bolt 50 extending through the registering holes securing the plate portions to each other.

At one side, the top plate portion 28 is enlarged as indicated at 54 which enlarged side is formed with an arm 56 extending longitudinally and forming an extension of the body, positioned along the adjacent side of body 30 of bottom plate portion 26. The arm 56 is curved at its free end and is formed with a threaded hole 58- at said end. The enlarged side portion 54- is formed with a narrow slot 60 horizontally disposed as viewed in FIG. 7, extending substantially the length thereof. An elongated slot -62 is formed in the plate portion 23 which slot a2 is closed at its ends and communicates with the slot 60 and intersects and opens out through the side of the enlarged portion as indicated at 64. The floor of the slot 60 opposite the side opening 64 is formed with a notch 66 along its outer side edge.

A principal feature of the present invention is an elongated, thin, flat presser plate 7% slidably fitted in the slot 60 in the top plate portion 23. The presser plate is preferably formed of springy metal. With particular reference to FIG. 4, plate 70 comprises an elongated, narrow, thin, flat body 72 having straight sides '74 and 76. At one end, the side 76 curves toward the side '74 forming a curved end 78, conformable in shape to the rounded edges of the bodies of the bottom plate portion 26 and top plate portion 28. The body 72 at its end opposite the curved end '78 is enlarged along the side 7d as indicated at 88 and formed in the center of the enlargement is an elongated slot *82 closed at both ends. The enlargement is formed with an extension along the edge 74 forming a narrow presser finger 84. A finger piece of knob 86 extends from the surface of the body adjacent the curved end thereof for manipulating the presser plate.

The presser plate '76 is substantially the length of the body of the top plate portion 28 and the arm 56 so that when the presser plate is in position, as shown in FIGS. 2 and 3, in the slot 60, the finger piece 86 extends through and outwardly of the slot 62 in the top plate portion 28 and is adapted to ride therealong, and the elongated slot 82 is over the threaded hole 58 in the arm 56 of the top plate portion 28. A headed and threaded bolt 88 passing through slot 82 is anchored in the hole 53 and guides the sliding movements of the presser plate and holds the presser plate in moved adjusted position. The finger piece 86 engaging the ends of the slot 62 limits the movements of the presser plate, the notch 66 providing a clearance for the bottom end or" the finger piece.

In operation, the presser plate 70 is moved by means of the finger piece 86 outwardly of the main guide plate portion 26 over the rim of the drive wheel 12. A pair of

skins

90 and 92 to be sewed and having fur 94 are fed to the discs or wheels 16 and 12 with the fur sides abutting to be pressed together for stitching. The edges of the skins engage the underside of the presser finger as as they pass between the discs or wheels thereby guiding the movement of the fur material so as to prevent irregular stitching, and especially when overseaming. The finger 84 is disposed sufiiciently close to the flange of the feed wheel 12 to prevent the fur as well as the material from lapping over the face of the feed wheel and thereby further avoiding irregular stitching.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and that various changes and modifications may be made Within the scope of the invention as defined in the appended claims.
