Application ineal May 7,
Fig. l is altace view or" a double-bar clamp embodying one form which ymy invention may assume.
Fig. 2 is ak view oit the adjustable jaw thereof in longitudinal section, with the tierods broken away.
Fig. 3 is a view -in transverse section on the line 3 3 ot Fig. 1.
Fig. e is a view corresponding to Fig: 2, but showing separate plungers for operating the two clamping-dogs. Y
F ig. 5 is a face view of my invention as embodied in a single-bar clamp.
My invention relates to an improvement in clamps ot the type shown in United States Patent No. 1,126,116, granted to me January 2G, 1915, the object being to produce a clamp constructed with particular reference to lightness, simplicity and ewness of parts, compactness ot' form and ruggedness in use, and convenience and ease of operation.
Wvith these ends in view, my invention consists in a clamp having certain details ot construction and combinations of parts as will he hereinafter described and particularly pointed outin the claims.
In carrying out my invention, as shown in Figs. 1 to 3 inclusive, the clamp comprises the usual parallel tie-rods 10, a cross-head 11 carrying a clamping-screw 12 having a slip-handle 13, a screw-actuated jaw ld sliding on the said tie-rods 10, and an adjustable jaw 15 also sliding on the tie-rods 10 and chambered to receive two complementary rdogs 16 pivotally mounted upon pinsy 17 and h ving their outer ends serrated for engagementwith the inner faces ot the respective tie-rods 10, while their inner ends are formed rounded coupling-lugs 18 entering with eoiu'iling-notches 19 formed in the opposite edges of a plunger 20 mounted in the block at a point midway the length thereof, between the said dogs and arranged with its axis parallel with the axes of the tie-rods 10 ot the clamp. At its inner end, the plunger is formed with an axially-arranged stop in the form of a stem 21 encircled by a helical spring 22, which exerts a constant effort to move 1the plunger rearward and hence to turn the jaws into position to grip the said tie-rods. The said stem 21 is adapted in length to engage with the inside ofthe jawface 23 ot the block, so as to limit the movement ot' the plunger and prevent the undue compression ot" the spring.
Under the construction described above,
1924. srial N. 711,622.`
beth dogs are concurrently operated by direct endwise pressurel upon a single plunger requiring no more space between the tierods .tor its operation than will permit ythe introduction a thumb or iiigerbetween them.
ln the modiiied construction shown in Fig. 4, two plungers 24 are provided for the operation of the respective dogs, instead of one, there being no'other difference in the principle of construction and operation.
In the single-bar clamp embodying my invention, shown by F ig. 5 of the drawings, the tie-piece consists ot' a bar 25 mounting a head 26 carrying' a screw 27 having a sliphandle 28 and engaging with and operating a` sliding-jaw 29 corresponding to the screwactuated jaw 1e ot the double-bar clamp already described. rlhe tie-bar also mounts 7' an adjustable block 30 sliding upon it, having a jaw-tace 31 co-acting with the tace 32 ofthe jaw 29 and mounting a dog 33 turning upon a pivot 34, having one end serrated to engage directly. with the bar 25 and its opposite end formed with a rounded coupling-lug 35 entering a coupling-notch 5G in a spring-actuated plunger 3? corresponding in construction and function to the plungers already described.
In the several embodiments olE my invention herein shown and described, it is characterized by a dog pivotally mounted in a sliding block iu position to grip a tie-piece or corresponding member oi' the clamp and operated directly by a plunger also mounted in the block.
I claim:
1. In a clamp, the combination with atie-member, ot' a bloclr sliding thereupon and having a clamping-face, a dog pivotally mounted intermediate of its ends directly in the said block for bodily move nent therewith, a plunger mounted in the said block, operatively connected with the said dog and positioned to be manually operated by a blow for disengaging the dog from the tiemember, and a spring acting directly upon the said plunger for normally maintaining the said dog in engagement with the said tie-member.
In a clamp,pthe combination with a. tie-member, of a block sliding thereupon and having a clamping-tace, a dog pivotally mounted intermediate of its ends directly in the said block for bodily movement therewith and provided with a cou-
