CLAMP Filed Feb. 26, 1934 INVENTOR E. r/THORNUNG ATTORNEY Patented July 23, 1935 so STAT- 5 c .i. 7 t n 1'1; Y j 11 claims. This invention relates to clamps and more par} ticularlyto hose'clamps. 'In a hose clamp particularly of the type employed inth'e cooling systems of gas" engines, it

5 is iessential that the clamp be of such construcpear fromv the detailed description and claims when'taken with the'drawihg in'which Fig. 1* is a perspective view of a Tpr'eferrd'form of clamp; Fig. 2 is a perspective-view of a slightly diif'erent form of clamp; Fig. 3'is carper'spective view of "a I modified form oft-clamp, and "Fig. 3a is a fragmentary sectional" view thereof: taken substan-* tially on' the line 3+3 of Fig. 3;, Fig. 4 is'a perspective view of an additional modified 'f'orm of clamp, "and Fig. 4a is a fragmentary sectional view thereof takenrsubstantiallyon"theline 4'-'4 of Fig. 4; Fig. 5 is a perspective view of another modified form of clamp; and Fig. 6 isia perspective view .of a still further modifiedio'rmof'clamp'; Referring especially to Fig. 11,.5 designates a strip having therein one. 'large centralaperture and two small lateral-aperturesjand 6 designates ai'strip' similar in shape to strip *5 and'having similar apertures therein," except that its central aperture is "threaded. 'A' piece ofrwi're '1 has one of itsends" 8 extending througha lateral aperture in the strip '5 and then clinched back-upon itself, while the other end 9 ofthislpiece like wise extends through a correspondingaperture in the strip .6 where it is clinched upon itself. Aseccnd piece; of wire ill has'its'freeend's simie lafly extending through theother lateral iaper; tin'esefithe strips 5 and; Efwhere thesezends are clinched upon themselves in a manner similar to the ends 8 and 9 of the piece I. A bolt/H passesrthroughthe central aperture in :the strip iandlmakes threaded engagement with the central threaded aperture in' the strip '6 so that these strips cail be drawn'together or separated ;to tighten or loosen theclamp' as desired." In order to bridge the. space. between the strip 5 and iii a single loop of wire I 2 has'it's free ends attached tothe strip '6 and hasitslooped end extending between the wirsland fi adjacent strips I'he fastening of the loop i=2 to the strip fi isiefiected lay-wrapping the partit of the loop about this Application February 26, 1934; Serial No. 712,958,; a

strip"with the end po'rtio'nof the wire being clinched against one face of the mentioned strip. Similarly. the other end portion of the 'wire'of theiloo'p: l2 'has' a part i5 wrappedabout the. stripe with the extreme end portion is of :the wire clinched against one face of thestrip. In this manner the loop 12 is securely fastened 'to the strip 8. p. J

In't-he formrofv clamp shownin Fig;--2 there are two g-metaljstrips 20 :and;2| each having therein twolateralapertures and a large central apertureof which the central apertureinythe strip 2| 'isr'threaded. A piece of wire,22jof arcuate form has one free end 23' extending'through lateral aperture in the strip 26! where it is clinched upon itself.- The other endof this wire',-as indicated at extends through a lateral aperture in the strip 2| and after being looped aboutv'a' portion of; this strip extends as part '25 having its freeend, 26 projecting intothe space between the wires -22-and 21'adjacent the, strip 263. A second piecexof wire 21 identical in'shape and arrangement with the wire 22, has one free end 28 extending-through the other lateral aperture of the strip qzlkwhere it is clinched backfupon itself. Theother free end of they Wire's? after it is looped about a portion of the stripiat 29; then extendsasa part -30 tohridge the gap-leetween the strips ZBand 2|. Wire has its'free end 32 extendinginto the space between the

wires

22 and 21 adjacent its strip 253. Thus thisform ofcla mp includes lout two pieces of WHB; -v i In'themodified form of the invention shown in Figs. 3 and 3a thereare provided two'notched or apertured; metal strips 35 and, wherein the notches in the strip 35 extend along its edges while in the stripifefi-thenotches are provided only in theends thereof. Thestrips jfi, and 36 each has a central aperture thereinofwhich the aperture-in-the strip; 36 is threaded; Aloop of wire 4 bridges ;thezg ap b etweenj the strips 35 and 3S and has its, free ends AI and 42 wrapped around a centra1stud,43; in the strip-BE which stud is formed by the mentioned notches. A single piece of wire intermediate of its ends is wrapped about the ends 4;! and 42 of the loop in the mentioned notches in strip 35 and is then bent into arcuate form as indicated at. and 45.- The free end 46 of,,piece M is inserted into the end notch in the strip 35 and-the material at this end of thisstrip is then compressed to grip the portion of;wire adjacent its upset end 46. The end portion of the arcuate'part '45 of the wire engages an end notch in the strip 36, being gripped therein adjacent the upset free end 41 of the wire. Preferably the upset ends 46 and 41 are sharply bent at right angles to engage the edge of the strip 36. A bolt 39 passing through the central aperture in the strip 35 makes threaded engagement with the central threaded aperture in the strip 36 so that the clamp can be loosened or tightened at will.

The modified form of the invention shown in Figs. 4 and 4a is identical in constructionwith the form of clamp shown in Fig.3, except that the

end portions

46 and 41 of the

arcuate portions

44 and 45 of the wire extend through lateral apertures in the piece 36a and are there clinched upon themselves, instead of being fastened in the end notches or apertures of piece 36 as shown in Fig. 3. To facilitate the understanding of the construction of this form of clamp the corresponding parts thereof are designated by the same reference characters as were used in connection with corresponding parts of the clamp disclosed in Figs. 3 and 3a.

In the form of the invention shown in Fig. 5,"a strip 50 having a centrally apertured upstanding part and an angular portion is provided. The clamp also includes a strip 52 having a lateral notch and end notches or apertures therein as well as a central threaded aperture. A single piece of wire bent intermediate of its ends as indicated at 55 to engage the notches in the strip 52, is then shaped to form the arcuate parts 54 and 56. The free end of the wire part 54 extends through a lateral opening in the angular portion 5 I, and is then bent back upon itself at 53 to grip one surface of the portion 5|. The arcuate wire part 56 similarly extends through a lateral opening in the angular portion 5| and is then bent back upon itself at 51 to grip one surface of this portion. A second piece of wire 58 is formed into a loop to bridge the space between the strips 50 and 52 with its free end extending between the wire parts 54 and 56 adjacent the strip 52. The ends of the wire 58 are attached to the strip 50 by being inserted through lateralopenings therein and being then bent back upon themselves as indicated at 59 and'60 to grip the surface of the portion 5|.

In the form of the invention shown in Fig. 6, a metal strip 65 having an upstanding part with a central aperture therein and an angular portion 66, is provided. A second metal strip 61 having a central threaded aperture therein and having a lateral notch and end notches or apertures therein, is also provided. In this form of clamp but a single piece of wire is employed. This piece of wire is bent intermediate of its ends as indicated at 13 to engage the notches in the strip 61. Thereafter, the parts of this wire are shaped into arcuate form as indicated at 69 and 69. The Wire part 68 after being inserted in a lateral opening in the angular portion 66, is wrapped around the edge of this portion to extend as a bridge H between the

strips

65 and 61, the free end of this bridge extending between the

portions

68 and 69 adjacent the strip 61. Similarly, the wire part 69 extends through a lateral opening in the angular portion 66 and is wrapped around an edge of this portion to extend as indicated at 14 as a bridge across the space between the strip 65 and 6Thaving its free end extending into the space between the

parts

68 and 69 adjacent the strip 61.

From the foregoing disclosure it will be seen that the clamp of this invention is sturdy in construction and is simple and economical to manufacture.
