Claiins.

This invention relates to sewing machine supports, either stationary or portable, and particularly to a table, cabinet or other support provided with means for resiliently carrying the bed plate and sewing head of a sewing machine.

One of the objects of the invention is to support the sewing mechanism in an efficient manner and to eliminate sidewise vibration and vertical movement of the mechanism relatively to its support.

Another object is to support the sewing mechanism Without the aid of clamping or fastening means, thereby permitting the machine to be placed on its support and to be removed therefrom with the utmost ease.

In the drawings:

I Fig. 1 is an, e1evational view of a conventional sewing machine head and bed plate, mounted on a support embodying my invention, the support being shown in section and partly broken away.

Fig. 2 is a fragmentary, longitudinal vertical sectional view, on an enlarged scale, through the support and bed plate, taken in the plane of the line 2-2 of Fig. 3.

Fig. 3 is a fragmentary, transverse vertical sectional view, on an enlarged scale, through the support and bed plate, taken in the plane of the line 3-3 of Fig. 2.

Fig. 4 is a perspective view of the spring metal plate which constitutes part of the special mounting means in the support, detached from the other parts.

In that embodiment of the invention shown in the drawings, a conventional sewing machine comprises the bed plate It, upright standard ll, overhanging arm l2 and'sewing head l3.

The support for the machine may be a table, cabinet or the like, and its top i is cut away to present the vertical surfaces l5 and I6 and the horizontal surfaces H, for the purpose of forming a ledge and receiving and supporting the bed plate I0 of the machine. The special mounting means of my invention is located in the ledge portion l8 of the support as indicated in Fig, 2.

Said special mounting means comprises the spring metal plate l9 which consists of a curved plate member 20, apertured centrally at 2!, having fiat arms 22, 22 at each end, the arms 22 of each end being spaced apart as indicated at 23. The mounting means also comprises the solid stud shown herein in the form of a cylindrical member 24 preferably made of leather, rubber or other suitable material, together with three screws, 25, 25 and 26. The cylindrical member 24 is the weight carrying member. The spring metal plate I9 is secured to one end of the stud 24 by means of the screw 26 passed through the aperture 2| into the cylinder 24, with the convex surface of the member 20 toward the end of the cylinder 24. The stud 24 need not be cylindrical but may be square or other shape in cross section.

To attach the special mounting means to the support it, the portion [8 thereof is provided with bores or recesses adapted to receive the cylinder 24 of each mounting device, and after the cylinders have been positioned as shown in Figs. 2 and 3, the screws, 25, 25 are inserted through the spaces 23 between the arms 22 of the plate l9 and screwed into the underside of the part E8 of the support [4.

When attached to the support M, the cylinder 26 of each device will protrude somewhat above the supporting surface ll of the portion IQ of the support, thus presenting a surface 21 on which rests the bed plate l0 when the machine is in operative position.

The character of the material of which the cylinders 24 are made is such that it provides frictional engagement between the supporting cylinders and the sewing machine and prevents relatively sidewise movement between the parts. Furthermore, the resilient character of the spring metal plate, preferably augmented by that of the cylinder 24, is such that shocks are transmitted vertically to the plate, and sidewise vibration and vertical movement of the sewing mechanism is avoided.

The form of the several parts of my invention, their construction and assembled relationship, are such that the vibration and relative movement of the sewing machine and support found in prior art constructions are eliminated, and the usual shocks resulting from operation of the machine, especially when motor driven, are absorbed by the support without impartin vibrations to the sewing mechanism.

The absence of fastening and clamping means is a great convenience in placing and removing the machine from the support.

Changes may be made in the form and details of construction shown herein, without departing from the scope of my invention as set forth in the appended claims.

I claim:

1. A sewing machine support provided with means for mounting a sewing head thereon and retaining the head against vibration without the aid of clamping or fastening devices, comprising a supporting ledge provided with a vertical bore therethrough, a, weight-carrying member mounted in the vertical bore and projecting above said ledge, the upper surface of said weight-carrying member being adapted to frictionally engage the machine to be supported, a spring metal plate,

means connecting the plate to said weight carrying member beneath the ledge, said plate having end members, and means connecting each end to the under side of the ledge at a distance from the connection between the plate and said Weightcarrying member.

2. A sewing machine support provided with means for mounting a sewing head thereon and retaining the head against vibration without the aid of clamping or fastening devices, comprising a supporting ledge provided with a vertical'bore therethrough, a weight-carrying member mounted in the vertical bore and projecting above said ledge, the upper surface of said weight-carrying member being adapted to frictionally engage the machine to be supported, a spring metal plate having a curved portion, means connecting the curved portion to said weight-carrying member beneath the ledge, said plate having end members and means connecting each end to the under side of the ledge at a distance from the connection between the curved portion and said weightcarrying member.

3. The sewing machine support defined by claim 2, in which the curved portion of the spring metal plate is curved upwardly between the ends of the plate, and the weight-carrying member is connected to the convex surface of said curved portion.

4. A sewing machine support provided with means for mounting a, sewing head thereon and retaining the head against vibration without the aid of clamping or fastening devices, comprising a supporting ledge provided with a plurality of vertical bores therethrough, a weight-carrying member made of resilient material mounted in each vertical bore and projecting above said ledge, the upper surface of each weight-carrying memher being adapted to frictionally engage the machine to be supported, spring metal plates having centrally curved portions, means connecting the upper convex surfaces of the curved portions of the plates to said Weight-carrying members, said plates having end members comprising spaced apart fingers, and headed screws inserted between said fingers and into the under side of the ledge for connecting said plates to said ledge.

5. A sewing machine support provided with means for mounting a sewing head thereon and retaining the head against vibration without the aid of clamping or fastening devices, comprising a supporting ledge, a yielding plate, means connecting the plate tothe supporting ledge, a weight carrying member having an upper surface projecting above the ledge adapted to frictionally engage the machine to be supported, and means connecting the weight carrying member to said plate at a distance from the connection between the plate and said supporting ledge.
