GARDEN HOSE CLAMP Filed April 8, 1930 2 Sheets-Sheet 2 Patented Dec. 3?), 1930 ARTHUR P. HESLOP, F BRIDGER, MONTANA GARDEN -HOS E CLAMP Application filed April 8,

-This invention relates to hose clamps, and has for a particular object thereof the provision of a. device of this character so constructed that it cannot buckle, and pressure will be applied substantially uniformly about the surface thereof.

A further object of the invention is to produce a device of'this character which may be very readily contracted about the hose,

which will be durable and 'efficient in service and which may be readily and cheaply manufactured.

A still further object of the invention is the production of a device of this character which may bemade adjustable as to length.

These and other objects I attain by the construction shown in the accompanying drawings wherein, for the purpose of illustration, I have shown a preferred embodiment of my invention and wherein:

Fig. 1 is a side elevation of a hose clamp constructed in accordance with my invention shown as partially applied to the hose;

Fig. 2 isa view similar to Fig. 1 showing the clamp fully applied;

ig. 3 is a perspective view of the member;

Fig. 4 is a view similar to that of Fig. 1, but showing a hose clamp adapted for use with larger hose;

Fig. 5 is a view similar to that of Fig. 4, but with the clamp fully applied, the lever being illustrated in position to shift the bar through the bridge; and

Fig. 6 is a side elevation of the clamp shown in Fig. 5.

Referring now more particularly to the drawings, the numeral 10 generally indicates a main clamping band of slightly greater length than the circumference of the largest size of hose with which its use is contemplated. At thereto a guide comprising parallel arms 11 connected at one end by a bridge 12. The free face of this bridge adjacent the band is angularly undercut as indicated at 13. The under surfaces of arms 11 are arcuately curved as at 14 to approximate the curvature of the surface of the hose with which bridge a v series pockets.

with the bridge by -21; In either construction the bar is transone end this band has secured 'W 1930. Serial No. 442,669.

the clamp is to be employed. Adjacent its center the band 10 has secured thereto one end of an auxiliary clamping band 15, this attachment being preferably accomplished by pressing the body of the band 10 to form of pockets 16, the mouths of which confront the bridge, 12 and providing upon the end of the auxiliary clamping band a hook 17 for selective engagement in said The free end of the auxiliary clamping band has pivotally connected thereto a latch bar 18, the under surface of which is curved similarly to the curvature of the under surfaces of the arms 11.

is adapted to extend between the and through the bridge 12 and has upper surface thereof at least one arms 11 upon the shoulder which maybe engaged simultaneously with the bridge to cause longitudinal shifting of the bar between-the arms and through the bridge and thus a tightening of the band upon the hose.

In Figs. 1 and 2, a single shoulder is provided by forming upon the upper surface of the bar a lug 19, this construction being preferably employed with hose clamps for relatively small hose and the lug 19 being adapted to be engaged simultaneously with the bridge by a pair of pliers.

y In Figs. 4 to 6 the upper surface of the bar is notched as at 20, to produce a plurality of shoulders which. are selectively engageable alever bar designated at versely perforated by a series of openings 22, therebeing a plurality of such series and the openings of said series being arranged at an angle to the bar differing from the angle of the undercut 13 of bridge 12 so that the openings of each series are consecutively exposed at this undercut.

In use, the clamp is placed about the hose ith the free end of band 10 underlying the bridge-equipped end thereof and the bar 18 extended between the arms 11. An implement is then employed to shift this arm longitudinally until the band is properly tightened, when a pin 23 of any suitable character is inserted through theopening most nearly ad jacent the face of the bridge. Attention is This bar directed to the fact that any expansion of the elastic material from which hose are ordinarily constructed will forcibly engage the pin against the inclined face of the undercut 13, wedging the bar 18 downwardly so that a secure frictional engagement is provided between this bar and the co-acting faces of the band 10.

Since the construction employed is obviously capable of a considerable range and change of modification without in any manner departing from the spirit of my invention, I do not wish to be understood as limiting myself thereto except ashereinafter claimed.

I claimi 1. A hose clamp, comprising a metallic band, spaced guides at one end of said band, a bridge connecting the inner ends of the guides, a second hand connected to the firstnamed band at a point intermediate the ends thereof, and a bar connected to the free end of the second hand and adapted to extend between said guides and through the bridge, the bar having a shoulder engagcable simultaneously with the bridge by a tool to thereby force the bar through the bridge, and means for maintaining the bar in adjusted positions with relation to the bridge.

2. A hose clamp, comprising a band, a bridge secured to one end of said hand, a bar operatively connected to the opposite end of said hand and adapted to extend through the bridge, the inner face of the bridge having an angularly under-cut shoulder, the bar having an opening for the passage of a pin to engage said shoulder.

3. A hose clamp, comprising a band, abridgesecured to one endof said band, a bar operatively connected to the opposite end of said band and adapted to extend through the bridge, the inner face of the bridge having an angularly under-cut shoulder, the bar having an opening for the passage of a pinto engage said shoulder, the bar and bridge having ortions simultaneously engageable by a tool whereby the bar may be shifted through the brid e.

4. A hose clamp, comprising a band, a bridge secured to one end of said band, a bar operatively connected to the opposite end of said band and adapted to extend through the bridge, the inner face of the bridge having an angularly under-cut shoulder, the bar havingan opening for the passage of a pin to engage said shoulder, the bar having on its outer surface a series of notches engageable by a lever disposed against the bridge as a fulcrum whereby the bar maybe shifted through the bridge.

5. A hose clamp, comprising a band, a bridge secured to one end of said band, a bar operatively connected to the opposite end of said band and adapted to extend through the bridge, the inner face of the bridge having an angularly under cut shoulder, the bar having a series of openings, said openings being arranged in angularly disposed rows, the angles of which with relation to the bridge vary slightly from the angle of the under-cut shoulder.

6. A hose clamp, comprising a metallic band, a bridge connected to one end of the band, said band having intermediate its ends a plurality of sockets facing the bridge, a second hand having a reverted end portion selectivelyengageable in any of said sockets and having at its free end a bar adapted to extend through the bridge, and means for securing the bear in adjusted positions with relation to the bridge, comprising openings in the bar for the passage of a pin and an undercut shoulder at the inner face of the bridge.

7. A. hose clamp, comprising a metallic band, a bridge connected to one end of the band, said band having intermediate its ends a plurality of sockets facing the bridge, asecond hand having a reverted end portion selectively engageable in any of said sockets and having at its free end a bar adapted to extend through the bridge, means for securing the bar in adjusted positions with relation to the bridge, and shoulders upon the bar engageablesimultaneously with the bridge by a tool for forcing the bar through the bridge.

8. A hose clamp comprising a band, a bridge secured to one end of said band, a second band adj ustably connected with the firstnamedband in the ends thereof, a bar operatively connected to the free end of the lastnamed band and adapted to extend through the bridge, the inner face of the bridge having an angularly under-cut shoulder, the bar having an opening for the passage of a pin to engage said shoulder.
