Specification of Letters Patent.

Patented Mar. 28, 1.922.

Application filed August 12, 1321. Serial No. 491,706.

T 0 all whom it may concern.

Be it known that LJOHN T. Sroxnr, a I residing at Cleveland, county of Cuyahoga, and State of Ohio, have invented a new anduseful of which the following is a specification.

My invention relates to clamp means adapted to firmly lock and readily unlock objects to or from each other.

The obj ect of my invention is a simple and efficient clamp means which is easily applied removed, which i'irm'ly locks the members to which itijsapplied, which readily releases these members when so "desired, and which-does not get out of order easily.

I attain this object by the mechanism illustrated in the accompanying drawing in which Fig. 1 is a side view ofa clamp; Fig. 2 is an end view of Fig. 1; Fig.- 3 is a side view of a clamp applied 'toa pairof flasks having hooks; Fig. 4 is an end view of Fig. 3; Fig. 5 is a side view of a clamp applied to a'pair of flasksjhaving tubes; and Fig. 6 is'an end view'of Fig. '5. 7

Similar reference characters refer similar parts throughout the views.

The clamp proper consists of the levers 10 and 11, and the pin 12.

The lever 10 has the prong l3 projecting from its main body at the upper end and terminates, at its lower end, in the ear lat which has an opening for the pin 12.

The lever 11 has the prong 15 projecting from its main body at the lower end and terminates, at its upper end, into the cars 16 which have openings for the pin 12.

' The pin 12 extends through all of the ears and slightly beyond them and is slightly riveted over at each end to retain it in place.

It is noted (Fig. 2) that the

edges

17 and 18 of the levers 10 and 11 are in alignment and that one side of each ear projects outside of the main body of the levers- This is for the purpose of permitting the clamps to be used in any position as illustrated in Figs. 3, 4, 5, and 6 for instance, and also to provide a pin of sufiicient strength and sufficient material in the ears for strength around the pin without cncumbering the levers as a whole with unnecessary material.

The

prongs

13 and 15, preferably, project from the main body of the levers substantially at right angles, but may be in the flasks E23 and ciined inwardly when desirable as seen in Figs. 3 and 4 for instance.

The levers themselves may be made of suitable lengths and it is preferred that both be of the same length from the center of the pin to the centers of the prongs.

on the lugs and consequently slippage of the clamp as a whole-endwise.

The clamp is here applied with the edges 17 prongs'are hookedover-the lugs. The wedge 20 is now driven in. between the flasks and the levers to hold the clampsunto the lugs and clamp theflasks to each other.

When the wedge is so driven in, the cenand 18' away from the flasks and the tral portion of the clamp moves outward while the prongs move inward, similar to the action of a toggle joint, and the flasks are firmly clamped and locked to each other.

In Figs. 5 and 6, the prongs project substa-nitally at right angles from the main body of the clamps and hook into the tubes 25 and 26 on the

flasks

27 and 28. The clamp is here applied with the edges 1'? and 18 toward the flasks and tho projecting portion of the ears away' from the flasks and is also applied reversed from the position shown in Figs. 3 and at. The wedge 20 is driven in as above set forth, one face thereof bearing against the flasks while the opposite face bears against the circular portion of the ears.

iVhen the wedge is so driven in, the central portion of the clamp moves horizontally outward as above set forth and both flasks are firmly clamped and locked to each other.

This clamp may be applied in different positions, upside-down, or end for end (as partially illustrated in Figs. 3, 4, 5, and 6) as may best suit any general or particular purpose.

When the clamp is applied as seen in Figs. 5 and 6 for instance, the upper and lower edges of the wedge bear against the

edges

17 and 18, respectively, when the clamp is applied, the wedge will. thereby be held in position up and down although there usually is sullieient :triction between the wedge and the fi- SliS to prevent-such up and down slippage of the wedge. However, the leverage oi? the toggle joint is here reduced since the wedge acts against the levers at a point between the prongs and the pin 12.

When the clamp is applied as seen in Figs. 3 and itor instance, the wedge acts against the circular portion of the ears whereby the fullest possible leverage is attained but the wedge is here not guided by the levers. There is little danger, however, that the wedge will slip out of place since considerable friction exists between the flasks and the wedge to retain the same in position.

It will be seen that this clamp means is etlicient since it firmly clamps and locks the flasks together so that they can be moved about without danger of coming loose and since it is easily and quickly applied or re moved, and since it may be applied in difierent positions; that this clamp-means is simple of construction and not liable to get out of order; and that this clamp means is inexpensive oi first cost.

I claim 30 "l. A clamp means comprising a clamp composed of two levershinged together and each provided with means for engaging an article, and means for forcing the central portion of said clamp outward in a manner similar to a toggle joint.

2. A clamp means comprising a clamp composed of two levers hinged together and each provided with an angularly projecting prong, and means for forcing the central portion of said clamp outward in a manner similar to a toggle joint.

3. A clamp means comprising a clamp composed of two levers hinged together and the outer end of each provided with means for engaging an article and the inner ends of both provided with ears and one side of each lever in alignment with the corresponding side of the other lever when both levers are fully extended, and means for forcing the central portion of said clamp outward in a manner similar to a togglejoint.

at. A clamp means comprising a clamp composed of two levers hinged together and the outer end of each provided with means for engaging an article and the inner ends of both provided with ears diametrically larger than the main body of the levers and extending beyond this main body on one side only, and means for forcing the central portion of said clamp outward in a manner similar to a toggle joint.

5. A clamp means comprising a clamp composed of two levers hinged together and each provided with a prong projecting from its main body at an inner angle of less than 90 degrees, and means for forcing the central portion of said clamp outward in a man ner similar to a toggle joint.

6. The combination with a pair of flasks, of a clamp composed of two levers hinged together and provided with means for engaging said flasks, and a wedge between the walls of said flasks and the central portion of said clamp to force this central portion outward and lock said flasks to each other.
