Description
'To all whom it may concern:
dilated aie @anni @Milice CHARLES B. GAFIELD, OF ORISK'NY, NE-WYORK.
Letters` Patent No. 102,487, lated May 3, 1870.
IMPROVEMENT *IN- CLAMP.
Th Shedule referred to in these Letters Patent and making part of the same I' 'Be itknown that I, CHARLES B. OA-Nrrnnn, of the village of Oiiskany, in the county of Oneida. and State of New York, have invented certain new and useful Improvements in Bench-Clamps; of which the following is a specification.
Nature mul Objects of my Invention.
the top o'r side of a work-bench, and of performing the offices of a vise, and also hand-screws, in gluing together small articles, shall at the same time be easily and quickly operated.
Description of thc Accompanying Drawing. d The accompanying drawing shows a side view of a ncli-clamp embodying my invention.
@he full view shows the positions' of the eccentric and levers of the clamp, when said clamp is grasping a piece of work.
`{Iliedotted lines show the position of the eccentric and' leversV of' the said clamp, 'when said clamp is not in use.
I'iglue 2 is a side and top view of the niain lever of' the bench-clamp.
Figure 3 is a side and top view of the shaft and argini' the bench-clamp. t
Fignre 4 is a side and top view oi' the eccentric and hand-lever of bench-clamp General Description.
A is a shait to be inserted in the work-bench or g-M is the foot of thelever1 and rests directlyuponthe object to be clamped. 'if' D is an eccentric.
@K is an axis on which this eccentric turns, and by which said eccentric is attached to the'lever D.
QE is a hand-lever connected with the eccentric D and turns the same.
QQ is the top ot' an ordinary work-bench. @P is 'an article to be held by the clamp.
Mode of Operation. Q The manner in which my improvement operates in .connection with a clamp such as described, is as follows. {The lower part of the shaft A is slipped into any. desired hole, as S, in the top or side of a bench, and
the article to be clamped bcingplaced under the foot M of the lever B, the shaft is allowed to settle down in the said hole until Stopped by the foot M,restin gl upon the article I?.
In order to clamp an article as P, securely, the opi erator takes hold of the leverfE, and turns it backi ward away from the axis C. l
' .As the lever E moves, it turns the widest part of the eccentric vD upon vthe plane H, and thus raises the short end of lever B and depresses the'long end and' foot of the said lever. But this is not all, the eccentri'el), in turning thus is forced up along the inclined plane H, and by this means the short end of the said lever B is raised higher than it could be. raised by an cccentric working upon a horizontal plane, and, as a consequence ofthe aforesaid combination of'an eccentric and the inclined plane, the short end of the lever B being raised considerably, the foot M on the long end of said lever will be at the same timevconsiderably depressed, and in practice it is found that when so depressed i't will hold the article to be clamped with greatV firmness, and this foot can be made to cause an indentation in the soft wood of an article placed under this foot of the clamp.
Claim.
if I claim vthe arrangement of the eccentric D, level Witnesses HENRY C. BUELL. J. H. BUELL.
