GARRY P. VAN WYE, OF NEW YORK, N. Y.

SEWING-CLAMP.

,To all 'whom it may concern.'

Be it known that I, GARRY P. VAN 'WYin a citizen of the United States, residing at New York, in the county and State of New York, have invented a new and useful Sewing-Clamp, of which the following is a specification.

This invention relates to clamping dcvices; and has for its object to provide a clamp for ladies to be used in sewing, cutting patterns, and similar purposes; a further Obj ect being to rovide a clamp that may be adjusted to hold) the work at one side of the table, or reversed to hold the work on the table.

The invention is illustrated in the accompanying drawing, in which- Figure 1 is a vertical section of a sewing clamp constructed according to my invention, and an elevation of the clamping means to secure it to a table; Fig. 2 is a view similar to Fig. 1, showing the clamp reversed; also a modified form of locking point; Fig. 3 is a top plan view of the clamp in the position shown in Fig. 2; and, Fig. 4 is a view similar to Fig. 1, showing a modified form of construction.

In the accompanying drawing the several parts are indicated by numerals of reference; and in practice I provide a sewing clamp comprising a clamp 5, U-shaped in form, provided with a thumb screw G, by means of which it may be secured to a table, or other support 7 To the arm S, is secured the sewing clamp proper comprising a lower plate 9, an upper plate 10, and a sliding sleeve 11. The two plates 9, and 10 are secured to the arm 8 by a single rivet 12, so that the sewing clamp is free to swing on this rivet; and the sleeve 11 is proportioned in size so as to slide freely on the plates 9 and 10, but at the saine time to hold the plate 10 directly over the plate 9 without lateral movement independent of the plate 9, thereby assisting the rivet 12 to hold .these two plates in alinement.

The plate 10 is provided with a bend at 13 so that when the sleeve 11 is in the position shown in Fig. 2, the angled end 14,

will be held free from contact with the plate 9, but when the sleeve 11 is brought to the position shown in Fig. 1, this angled end will be brought down into contact with the end of plate 9, and will form a clamp in con nection therewith, as will be readily understood, and will securely hold any garment, or cloth that may be placed between the same, the degree of grip depending upon the adjustment of the sleeve 11.

In order that the sewing clamp may be adjusted to extend over the table as shown in Fig. 1, or to one side of the table as shown in Fig. 2, I provide the end of the arm 8 with an upward projection, or point 14, or pin 14', and the plate 9 is provided with two holes l5, and 16, equidistant from the rivet 12, which is the pivotal point, and so disposed that when the sewing clamp is in the position shown in Fig. l, the point 14 will engage the hole 15, but when the clamp is in the position shown in Fig. 2, thc point 14 will engage the hole 16, and this point is raised sulliciently so that it will enter these holes far enough to form a stop, or lock to hold the clamp from swinging when adjusted to either position. At the same time, this point 14 does not enter either hole far enough to prevent the ready disengagement of the same by exerting pressure on the end of the sewing clamp owing to the fact that thc plate 9 is composed of semi-spring metal, such as cold-rolled steel, and the holes 15 and 16 are a sufficient distance from the pivotal, or holding point, to allow for the slight upward spring of this plate at either end to pass over this point, as will be readily understood. This spring action is so slight that spring steel is not required, and any hard material possessing a slight spring action will operate successfully.

In operation, when desired to use the clamp at one side of the table, it is placed in the position shown in Fig. 2, but when desired to work on the table as in cutting patterns, the clamp is placed in the position shown in Fig. 1; the work is inserted between the end of the plate 9 and the angled end 14, the sleeve 1l is pressed forward until the material is securely clamped in position, and may be held in that way as long as desired, the slide remaining in adjusted position by friction, and is slid back when desired to release the work.

As shown in the drawing, the plate 9 is made considerably thicker than the plate 10, and the plate 10 is provided with the upwardly projecting end owing to the bend at 13. Owing to this construction, when the sleeve 11 is slid toward the end to clamp the material, although the plate 9 is composed of semiespring material, most of the spring action will take place in the plate 10, and the plate 9 will be held substantially parallel with the table thereby preventing the raising of the work from the table.

In the construction shown in Fig. 4l, the arm 8, is provided with two holes 15 and 16, and the plate 9 is provided with a locking point 111, which engages these holes respectively, the action being the reverse of that shown in Figs. 1 and 2, the operation being otherwise the same. In this figure I have also shown the ends of the plates 9 and 10 curved downwardly and outwardly, so that the clamping end of the plate 9 will rest upon the table. This construction may be found desirable in holding patterns close to the table instead of in a slightly elevated position, as shown in Fig. 1.

It is evident that other forms of clamping devices may be used to hold the clamp to the table, and also that other clamping means may be used instead of the spring plate and sliding sleeve, and at the same time provide means to reverse the'clamp to hold the material over a table or at one side and lock the clamping means in more than one position, and I reserve the right to make such changes.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is*

1. A sewing clamp comprising two clamping members one of which is adapted to secure the device to a support and the other to hold the sewing, or material, one of said clamping members being pivotally mounted on the other, and means to lock the pivotally mounted member on the other in different positions.

2. A sewing clamp comprising two clamping members, one of said clamping members being adapted to secure the device to a support, and the other being adapted to hold the material or sewing, said members being pivotally connected, one of said members having engaging means, and the other member having a plurality of oppositely disposed engaging means equally distant from said pivotal connection whereby said members may be locked together in different positions.
