l HOSE CLAMP.

App1icati'on filed November 2, 1922. Serial No. 598,644.

To all whom it may concern.'

Be it known that we, FRED A. RICHARDS, FREDERIC C. BooHA'rEY, and JOHN T. JONES, citizens of the United States, residing at Golden, in the county of Jefferson and State of Colorado, have invented certain new and useful Improvements in Hose Clamps; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. n

Our invention aims to provide a simply constructed and inexpensive clamp whereby a hose, such as a re hose, may be compressed or flattened to cut off the iiow of water.

In carrying out the above end, we provide a base, a hose clamping lever fulcrumed on said base, and a hand lever engaged with said hose clamping lever for operating the same, a further aim being to provide an eye at the upper side of the base with which a claw-like end of the hand lever is engaged for operating the other lever, after which said hand lever may be partly inserted through said eye to hold the two levers in operative position.

A still further* object is to provide an anti-friction roller and unique mounting means therefor, facilitating insertion of the hand lever into and withdrawal of said lever from the eye.

Vith the foregoing in View, the invention resides in the novel subject matter' hereinafter described and claimed, the description being supplemented by the accompanying drawing.

Figure 1,. is a side elevation.

Figure 2 is a top plan view.

Figure 3 is a view similar to Fig. 1 showing a different position of parts.

Figure 4 is a detail section on line 1 -4 of Fig. 2.

In the drawings above briefly described, the numeral 1 designates a suitable base which may well be formed of wood provided with a metal cover 2 suitably secured thereto by rivets or the like In the present showing, one end of the base 1 is reinforced by upper and lower transverse bars 1 and 5 which are riveted or otherwise secured thereto, the ends of the bar 5 being by preference bent downwardly and suitably shaped to form prongs 6 which prevent 'slippage of the. base upon thepavement or any other `surface which may support it.

Suitably. secured to and` risingv from the bar Ll; are a pair of bearing lugs 7 to which one end of a hose clamping lever 8 is ful4 crumed, as indicated at 9. The other end of lever 8 is preferably offset as seen Vat 10, is bent laterally as indicated at 11 to form a shoulder for engagement with a hand lever 12, andis finally bentfagain to provide a finger 13 which is spaced from and parallel to theI body portion of the lever 8.l

The hand lever 12 engages the bent portion 11 ofthe lever y8 between the body of this lever and the linger 13 and is providedk with a claw-like end 141 which is engageable with an eye 15 at the upper side of the base 1, whereby swinging of said hand leverf12 toward the `base will flatten the hose H placed upon said base between'the lugs 11 and the eye 15, Aas'shown fully in Fig.r 3.

Then, by inserting the lever 12 partly through the eye 15,r said lever will engager the base and eye in a binding manner, thereby holding `theclamping lever 8 in operative position. a pin 16 for passage'through an openingvl? in the hand lever 12 to prevent it from being accidentally withdrawn from the eye 15. This pinniay well bey connected with the base by a suitable chain or the like 18.

The eye 15 is preferably formed by a U- bolt vwhose arms 19 are reduced and pass through the base 1 and its metal cover 2- These arms also extend through outwardly extending ears 2O on a pair of upright bear' If desired, we may provide f from the details disclosed, they are preferably followed, but within the scope of the invention as claimed, numerous minor changes may be made.

l/Ve claim: f 1. A hose clamp comprising a base, a

lever fulcrumed on said base for clamping hose against the same, an eye on the upper side of said base beyond which said lever swings to clamping position, and a hand lever having ra claw-like end engageable with said eye, wsaid hand lever having an operating connection with the first mentioned lever, whereby swinging of said hand lever toward said base will move said irst named lever to hose clamping-position, said hand lever being then insertible partly through said eye to hold the irst named leverin operative position.

2. A hose clamp comprising a base, a hose `clamping 4lever fulerumed on said base for clamping a hose against the same, the free end of said lever being bent laterally andthen Jfurther bent into parallel relation with the body oi said lever, an eye on the base beyond which said bent lever end swings when moved downwardly, and a hand lever having aclaw-lile end received in said eye, said hand lever engaging said bent end of said hose clamping lever to establish an operating connection between said levers, said hand lever being partly insertible through said eye to retain the two levers in operative position.

3. A hose clamp comprising a base and a hose clamping lever fulcrumed on said base, said base having an opening beyond which said lever swings when lowered, a pair of bearings at opposed sides of said opening having vhorizontal ears contacting with the base, a U-bolt having lits ends passed downwardly through said base and said ears and securing them together, a roller in said opening mounted between said bearings, and a hand lever engaged with said clamping lever and having a claw-like end received in said U-bolt, said hand leverr being insertible partly through said U-bolt tor binding engagement with said bolt and roller to retain the two levers in operative position.

4. A hose clamp comprising a base, a hoefe-engagingy lever pivoted at one end on said base, the opposite free end of said lever being bent upon itself to provide a substantially U-sliaped portion, the bightportion of which constitutes a shoulder and the eX- tremity ot which is disposed in spaced parallelism to the body portion of the lever and forms a. confining linger, an operating lever for said iirst named lever, a portion of said operating lever being disposed between said finger and said body portion and bearing on said shoulder, and means for pivotally connecting the lower end of said operating lever to said base.

In testimony whereof we have hereunto aHXed our signatures.
