Letters Patent No. 107,398, dated September 13, 1870.

DEVICE FOR SECURING- COVERS UPON SEWING-MACHINES.

The Schedule referred to in these Letters `'Patent and making part cf the same.

To all whom it may concern Be it known that I, JOHN H. MOONEY, oft-he city and county of San Francisco, State of California, have invented an Improved Device for Securing Covers upon Sewing-Machines; and I do hereby declare the following description and accompanying drawing are sufiicient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvements, without further invention or experiment.

My invention relates to an improved device for scouring the covers which inclose'the mechanism of sewing-machines to the sewing-machine table, so that they will, when fastened, be h'rmly held, but can be removed when desired, by simply changing thev position ofthe device, so as to free it from the plate by which it is held.

In order to explain my invention so that others will be able to understand its construction and operation, reference is had to the accompanying'drawf ing forming a part of this speciticatiom in which- A represents the table top, of any oi' the various styles of sewing-machines, upon.wl1ich the working mechanism is fixed. l

In order to protect this mechanism from dust when `not in use, a case or cover is employed, which is fre.

quently made in two parts,and hinged together, so

'that the portion immediately over the cloth-plate can he turned back upon theother part, so as to expose enough ofthe mechanism to allow the machine 'to be used;

at or near its end, a lug or projection, b. This lug,

and t-hc lower end of the rod, enter a hole, c,`in a plate, It', which is made' fast to the table, as shown.

The upper endA of the rod F is formed into a suitable handle or lever, G, by which the rod can be turnel, so as to carry the lug b around under the plate E', to a position from which it cannot be released, owing to the peculiar shape of the hole c, which requires the lug to be in a certain position before it can pass through. l a

In order to make the fastening secure, and hold the covertightly down upon the table, the rod, and

.consequently the lug, is raised as the rod'is turned,

so as to press the lng against the under side of thel plate E', and thus drawthc cover C firmly down.

A spiral or inclined slot, a, is made at some con- .venient place along the length of the barrel E, anda pin, (l, projects from the rod F, through the slot. VAs the rod is turned, this pin follows the inclination of the slot, causing the end to be raised or lowered, according to the direction in which it is turned, but; raising it sufficiently, when turned in one direction, to bind the lug l1 against the under side of the plate E', thus drawing the cover-firmly against the table.

By turning the rod in the opposite direction the lug can be released, and the cover removed. v

This device, while being at once neat and convenient, is also quite effective, seeming the cover upon the table in a substantial manner, while it is capable of heilig removed at pleasure.

What I claim is- Iu combination'with the table and cover of a sewing-machine, the above-described device for securing In witness that the above-described invention isV claimed by me, I have hereunto set myhand and seal'.
