"WILLIAM u. FLOYD, oil1 BROOKLYN, n. 1)., WWYORK.
IMPRovi-:D ADJUSTABLE CLAM P.
4Specification fin-ming purl ol' Lr'tlers 1fatent No. 52,983, dated March 6,1866.
To all whom. 'it 'may muriera:
` Beit known that I, WILLIAM G. FLOYD, of the city of Brooklyn, E. D., in the county'ot Kings and State of New York, have invented anew and usel'ul Improvement on Foundry-4 Flask Clamps, ot' which the following is a full description ot' the construction and operation -ot the same, reference being hadlto the annexed drawings, making a part of the specification, in which- Figure l is a longitudinal elevation. Fig. 2
is a view of plan, showing surface,-&e. *Figa 3 'is the present style of clamp.
The stati' AA Fi v 'l is com osed of a )lain 1 ,la 7 l l piece of round or square iron, with a foot, B,
at bottom end, which catches under the bottom ofthe. flask or mold, as usualin the present style of clamps. lhe staft'A. can be any required length, o r can consist of-the present style of clamp it'the cn'd has been broken oft'. D is an iron plate or follower, and answers the double purpose of a tbundation for the cam E to jam on, at the saine time holding the stai A in its place to keep the caln E from rolling. The iron nut K has a round or'squarc oblique hole through it at C a little larger than the clamps over others now in general use for the reasons set'forth, as follows:
First, it will fit a greater number of different-sized flasks or molds.
Second, itcau be appliedquicker and taken 'ell'.quieker. and with less damage to a flask or mold, as a whole set or the usual number l'or a'llask ormold can be applie'd while the same number of the present style of clamp can hc selected from the usual pile as they are gen.- crally kept iu well-regulated foundries.
Third, my in1provementdispcnses with pinchhar, hammer, blocking, and wedges, the first of which destroys the fiasks,the'second end'angers the mold, the third, if piled too high, will tumble, and thc',:touith isusually asearcc article around a foundry. y
Fourth, my process isnsimplefal ways ready for any llask, no more 'likely to get out f .0rder than any other, aud-can be applied toa 'broken clamp of the old stylc'without welding. 4 It will be seen that a square hole iny the nut will answer for round iron as w'cll as square.
By raising thc staff A with one hand, allowing the foot to go under thcask, as with thc present modcof clamping, placing the plate or follower D on topof the flask, so that the points Ll L are oppositcaudthe cam .E on top, ot' plate, throwing the handle F back toward the staland lcttin g the nut drop as low as it will, then pushing the handle over in the direction 'of arrow, the whole becomes securely fastened. a v
foot B turned on bottom end.
What I do claim is- The nut K, of iron or other` metal, withthe round orsquare beveled hole C and cam E, in
combination with the said follower D, for the" purpose herein mentioned, and for other purposes, as shown in drawings, or otherwise as set forth-in specification.
i WM. G. FLOYD.
