CLAMP.

To all whom it may concern:

Be it known that I, GLENN Moran, a c1t1- zen of the United States, and a resident of Jamestown, in the county of Chautauqua and State of New York, have invented certain new .and useful Improvements in Clamps; and, I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and ,to the letters of reference marked thereon, which form a part of this specification.

; This invention relates to improvements in clamps and more especially to a clamp' adapted for use on a washing machine or similar device for holding down the lid or cover. Y

My improved clamp can be easlly and cheaply made, since the parts are cast and require no machining or dlflicult assembly. My clamp is also so designed that it can be attached readily to a washing machlne or other device, and is so constructedthat 1t may be operated easily, and willgivea maximum clamping efiiciency with a m1n1- mum effort. I

In that form of a device embodying the features of my invention, shown in the accompanying drawings Figure 1 1s a v1ew in front elevation, of

a washing machine with my improved clamp attached.- 1 v Fig. 2 is a vertical sectional view on the line 22 of Fig. 1, looking in the direction indicated by the arrows.

perfect I journal The journal part B has a triangular flattened portion 5 adapted to be attached to the lid 2 by means of the screws 6, 6, inserted through the holes 7 7. The part 13 projects beyond the edge of the lid 2 and has at its outer extremity a thickened part 3 depending below the upper surface of the lid 2. Extending vertically through the part 3 is a substantially circular hole 8 open along its inner side. The upper end of the vertical opening 8" has opening into it the square hole 9.

The rotatable bolt D is provided with the vertical opening'8 in the part At its upper end the boltD' is provided with the shoulder 12 and cross handle 10. .Near

the part B. The bolt may thenbe turned until the hook 13 extends. outwardly, or.

away from the flattened triangular part 5,

until-the shoulder stop 16flies under the bottom edge I of the 7 vertical opening 8, When in this position, the fillerblock E is inserted in the part B in order to provide a more perfect journal for-the bolt D, as hereinafter described;

Specification of Letters Patent. P t t J 1920 I Application filed. August 13, 1919., Serial No. 317,106. l

the rounded part 11 adapted to journal in The filler block E jlias its front face con- V caved as jindicatedby 15 to conform to the curvature of the rounded part 11 on thebolt 9. Thecurved face 15 of the part E is substantially the same length as the, rounded part 11. Theupper partofthe fillergblock E is squared as indicated by 17 and adapted 20 shoulder stop 16 operating against the lower 'serted intothe part B so that the squared part 17 lies in the square hole 9 and the shoulder 24 lies in the recess 21. When in this position, the concave face of the filler block E together with the circular-part of the opening 8 forms a vertical circular hole affording a journal for the rounded part 11 of the bolt D. The shoulder 12 prevents the bolt D- from moving downward and the edge of the'filler block E and lower edgeof the part 3 on the journal part B prevents the bolt Dfrom moving upward. The lower part of the filler block E is cut away as in dicated by 23 to accommodate the edge of the lid 2 of the washing machine. When the bolt D and the filler block E are in place in the journal part B this part is fastened to the lid of the washing ma hine as shown in Fig. 2 with the edge of the lid projecting into the cut away part 23 of the filler block E. It will be evident that when the part B a is firmly screwed onto "the lid, the edge oi: the

lid in the recess 23 of the filler block E will hold such filler block in place.

The catch part C of the clamp is a substantially square shap'ed casting, with a square recess 18 in the center and-a segmental tapered catch 19 at its upper edge formed around thesemi-circular recess 25.

This part is adapted to be fastened to the body 1 of the washing machine below the part B by means of the

screws

20, 20, in the

holes

22, 22. The parts are so arranged that as the lid 2 is closed the recess 25 will accommodate the shank of the bolt .D when the hook 13*is turned outwardly. After the lid'is closed, the bolt D- is rotated, bringing the hook-13 into engagement with the thin end of the tapered catch 19 on the part C.

v-Further'rotation ofthe bolt D will move the -'hook 13 across the segmental tapered catch 19 toward its thickened end, thus pulling the lid is closed, the stop 1 down the lid 2 and clamping it securely.

Fig. 7 shows a modified form of the device in 'whichthe thickened projection 3 of the journal part B is provided'at its lower. edge -with a stop 75 adapted to be engaged by the shoulder stop'16 on the rotating boltD so that when the bolt 13 is turned outwardly as 16 will be in engagement with the edge'76 of the stop 75,

' preventin rotationof the bolt D in one direction, It is obvious that with such a stop the, bolt D must be rotated in one direction only which will bring the hook 13 into ongagement with the proper end of the tapered catch 19; that is, with its thin end, so'

that upon further rotation of the bolt D, the

hook 13 will be moved across the catch 19 toward its thickened end, thus clamping and securely holding the lid. The general object of the shoulder 75 is to prevent an attempt to rotate the bolt D in the wrong direction.

If it were not for this stop 75, an ignorant operator might turn the bolt D in' the wrong directio'niand attempt to bring the hook 13 into engagement with the thick end of the catch19 first. The opposite edge 77 of the stop 75 will engage with the shoulder stop 16 on the bolt D and prevent too far rotation, in the event that parts have become worn or loosened to such an extent that s'ufficient force would operate to rotate the bolt D to such an'extent that the hook '13 would move across the entire surface or" the tapered catch 19 and slide off of its thickened end,

thus again releasing the clamp.

In Fig. 8 I have shown another modifica' 'tion of in device in which the catch '19 on the part is not tapered from one end to the other, but is thin at each end as indicated by 81, 81, and has its'thickest part in the center as indicated by 82. When the part C is formed in such a manner the hook 13 may be brought into engagement with the catch 19- from either end first.

In other words,

after the lid is closed the bolt D may be ro- 'tated in either direction to operate the clamp, the hook 13'engaging with the catch 19 at either end, 81, and drawing up on the vious that in the use of this modification the modification shown in Fig. 7 with the stop 75 should not be used, since" the bolt must be free to rotate in either direction.
