Torll whom it may concern:
Be it known that I, CHARLES Il. CORN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illivide an improved device of extremely simple Fig, 2'is a `plan view thereof.
construction which may be easily and quickly applied or removed and whichwhen closed upon a fabric will be extremely elcient as a clasp and notliable to accidental loosening,
l will describe my invention inconnection with the accompanying drawings, which illusu trato the preferredemhodiment thereof on an enlarged scale.
Figure l isa side elevation of the oiasp., Fig. 3 is a ver= tical sectional elevation showing the Ajaws open. Fig. 4 is an end \'iew,'tl1e jaws being open. Fig. 5 is a vertical sectional elevation similar to Eig. 3, but showing the jaws closed, Figo 6 is a crosseeotional view on line 6 i5 of Fig. 3, and Fig..7 is a cross-sectional view on line 7 7 of Fig.` 5.'
The sameletters of reference are used to designate the same parts wherever they are shown.
in the device shown inthe drawings a, U shaped frame av is provided, of which the l lower arm is formed to constitute a stationary jaw coperating with a movable jaw o, which is formed by a rocking? lever pivoted open e, pin b', supported in the upturned ends or standards c c, formed at the sides of said lower arm. The upper arm a of the frame extends forward over the movable awz, A wedge-block d is arranged to slide to and fro between the under side of the'upperiarm and the top of the movable-jaw lever b to actuate said jaw lever., The wedge-block is provided with a button d', the shankwhereof passes throughs slot in the upper arm d' of the frame. Said arm a may be provided with downwardly-projectingwebs dI a at the sides, which serve both to stitfen said arm and also as guides for the sliding wedge-block Thepivotal axisbA-of the movable-jaw lever is not at the extreme rear of the frame, butat at an intermediate point, and the mov,- able-,iaw lever is provided with .a rearward extension sloping upward behind .the pivotal axis. When the wedgebiock is moved rearwardly past the axis b','it engagesthe said upturned rearward extension, whereby the jaws arepositiveiy opened, the movable jaw b being rocked upon its pivot to the position shownin Fig. 3 When the wedge-block is moved forwards it presses upon the top of the movable-jaw lever and positively closes the same upon the cooperating jaw formed by the lower arm a of the frame, so that a fabric c, interposed between said jaws, is securely clamped, as shown in l. The jaws may loe roughened or inrnished with eetlior any other desired gripping-surfaces,
The forward portion oi the movablejaw lever 1ois motora-lily arched, as shown, so that it wiil have little spring or elasticity tees oonimodsiie itself to some extent to varying.;
thicknessesot fabric. The forward edge the wedge-block is preferably rounded ofi, shown, slide more eaeiiy over the top ot' the movablejaw ievern wiii appreciated that the device above described is extremely simpie'and moy be manufactured at small. cost. No springe are neceessny, the jaws being positively opened and oiosed by the movement of the sliding,1` wedgemilices.e Very little force is required to move the wedge'bioels in closing the jaws togetloei: When ciosed,tiiey hold the inter" posed 'fabric very tightly; but only a slight pressure i con the button d of the sliding wedge-bloei?. is required to' open said jaws An objection to clamps heretofore in use has been considerahlev 'force has been. `re. @ruined to open close them, and in de1 mn inw vicesso smalti it is diiicnlt to apply this presl sore withont the fingers.
it will ice understood that the form of :my
clasp may ice varied to a considerable extent 1.
