Application filed tlctober 8, 1910. Serial lilo. 586,055.

the following to be a full, clear, and exact des r ption of the invention, such as will enableogthers skilled in the art to which it oppertsins to make and use the some.

This invention relates to improvements in devices employed. for attaching hose cow 1 lin 's end for like ur oses end has for one of its objects to provide s simply constructed device whereby the couplings may be readily upplied to hose of various sizes and without the-necessit for em lo we: vise or other 3 P y a like implement.

With this end other objects in View, the invention. consists in certs-iunovel features of construction as hereinafter shown vland escribe i and then specifically pointed out the clcimgsnd', in the 'drewings illustrative of the preferred embodiment of the invention, Figure 1 is u side elevation, of the improved device, Fig. 2 is e plan. view of the some, Fig; 3 is a front elevation of the improved impleulent, Fig. t is an enlarged sec-.

tionsl. detail illustrating the construction of the reversible pin, 5 is an enlarged detoil oi the clamping frame detached, Fig. 6 is s transverse section, enlarged, on the line 66 oi. Fig. 2, Fig. '2 is s side elevation of the lows Of the device showing the pin in reverse position. 1

The improved device comprises two main. ermsfl0-ll pivotally united one end by a; detachable bolt 12 and out 13. The arm ll is provided'with an. outwardly di-' rooted jaw let, while the arm to is pnt vidcd with on opposing reversely curved jaw 15. The terminal of the jaw 14. is provided with o transverse recess 16, while the jaw 15 is provided with a. similar terminal recess 17, the two recesses being loceted directly opposite each other when jaws are in closed position, The jaw 15 is enlarged at its outer end with a threaded aperture through the enlargement to receive a threaded pin 19, the-pin being presided at its outer eudwith s. screw-driver receiving recess 29, sud out Oewoy at the other end-upon opposite sides,

being she greater angle then. the

asshowri at 21-22, the cut-sway ion 21 portion 22, as shown. The inner end: of the aperture for the pin 19 communicates with the recess 17, and is so located that when the p1n l9 is disposed with the larger cut-away portlon 21 toward the inner face of the jaw 15, no portion of the pin will project beyond the face of the jaw, andwhen the pin is re versed in position, or arranged with the smaller cut-away portion 22 presented in wsrdly or toward the inner face of the-jaw, a relatively large portion of the pin will pro ect beyond the inner face of the jaw, as

shown in Fig. 4, and likewise with its end spaced away from the free end of the j aw, so

that a shoulder is produced to assist in the operation of applying the coupling, as herematter explained. At its opposite end the arm 10 is provided with a relatively large ring 23, while the arm 11 is provided with a smaller ring 24 which registers with the larger ring 23 when the arms are disposed in one positiom'as shown in Fig. 1. The ring 24: is' internally threaded to receive a threaded stud 25 upon a hose fitting holding device formed with four outwardly curving arms 26, the arms being united at their outer ends to a. squure'portion 31. The outer faces of the arms are square represented in Fig. 6, to form gripping edges, as hereinafter explained,

Slidsble upon the arms 10l1 is an endless frame 2? having an enlargement 28 at one end and formed with a threaded sperture therethrough to receive a. threaded clamp pin 29, the letter having thumb plates 30 to enable the pin to be forcibly rotated. The freme 2Z'is provided with an internal shoulder 32 whereby a laterally offset socket is formed to beer over the arm 11, and thus slidsbly maintain the frame upon the arm 11 while the arm 10 is free'to move withiii the remaining portion of the frame, as in diceted in Fig. 5. The frame 27 and its pin 29 thus constitutes a. clamp device whereby the arms l(l1l-may be fo 'bly compressed wheri required. The s 2'? being slidable upon the arms -1, may be adjusted d extent, and the arm countersink recesses at vs the point of the clamp ut it from slipping when shown at The member26 together with its squurepoint 31 is designed to hold the coupling members while the hose is bemg strain applied. one of these recesses being applied thereto, and is adapted to hold hose I coupling members of various sizes. The relatively small terminal 31 is small enough to enter. the smaller coupling members, while the arms 26 at their widest points are adapted to engage within the larger coupling members. Any size of coupling member within the range of the curved arms 26 may thus beheld firmly while the hose is being forced thereon. The member 26-31 is "thus a convenient and useful adjunct to the implement and materially increases its efiiby compressing the members 10-41. The

toward the rings frame 27 is then moved 23-2 l and the screw 29 rotated to apply-the "requisite pressure to compress the sides of the clamp until the clamp bolts can be inserted. By this means any required pressure may be readily applied, and the resilient clamping ring closed to a sufficient extent to permit the insertion of the clamping bolt. Thus thebands may be applied to any'size of vhose without the necessity for employing a vise or other like implement.

By actuating the threaded pin 19 as before described, it may bemade to serve as a cam for forcing the tongue 22 into position and will further serve to engage the slotted way of the clamping member and insure the alinement of the bolt holes. The relatively large ring 23 provides an effectual means for suspendingthe implement from a nail or other support when not in use;

What is claimed is:-

1. An implement of the class described comprising two arms pivotally united near one end and with the shorter ends formed into oppositely curving gripping jaws with recesses in their terminals, one of said jaws being further provided with an aperture communicating with the terminal recess thereof, and a pin rotatively and adjustably supported in said aperture with its inner end reduced on one side, and means for reversing and adjusting-said pin. 2. An implement of the class described comprising two arms pivotally unitednear one end and with the shorter ends formed into oppositely curving gripping jaws, one of said jaws being provided with an aperture communicating with the terminal thereof, a pin rotatively and adjustably supported in said. aperture with its inner end-reduced on one side, andmeans for reversing and adjusting said pin.

3. An implement of the class described comprisingiftwo arms pivotally united near one end and with the shorter ends. formed.

into oppositely curving gripping jaws, one

of said jaws being provided with an aper- U ture communicating with the terminal thereof, a pin rotatively and adjustably supported in said aperture with its inner end reduced on one side, means for reversing and adjusting said pin, and a clamp device slidable upon said arms.

In testimony whereof, I aliix my signature, m presence of two witnesses.-
