Patented June 17, 1947 SWINGING HOSE GUIDE Otis D. Hitt, Bryan, Ohio, asslgnor to The Aro Equipment Corporation, Bryan, Ohio, a corporation of Ohio Application October 13, 1944, Serial No. 558,565

7 Claims.

This invention relates to a hose guide of the type having rollers for the hose and a mounting for the rollers that permits them to tilt with respect to a reel housing or the like.

One object of the invention is to provide a hose guide which can swing to permit the hose to be pulled from the housing at a greater angle than usual without undue bending of the hose at the point where it passes through the guide.

Another object is to pivot the hose guide in a simple manner with respect to the housing so that it can swing in the direction that the hose is pulled, thus reducing the bending of the hose through the guide.

A further object is to provide a frame having a subframe pivoted thereon, the subframe being formed of two members having complementary pintle seats to receive the pintles of the guide rollers and to also receive pintles for the subframe relative to the main frame so that the pintles are journaled in the pintle seats when the members are secured together by screws or the like.

Still a further object is to provide the subframe with a spherical wall fitting a spherical seat of the main frame to minimize the opening between the two frames in various positions of one relative to the other and to provide a novel stop means for the pivotal movement of the subframe.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, wherein:

Figure 1 is a front elevation of a swinging hose guide embodying my invention.

Figure 2 is a sectional view of my invention on the line 2-2 of Figure 1 and showing the guide swung in the direction that a hose therethrough is bent.

Figure 3 is a horizontal sectional view on the line 33 of Figure 1.

Figure 4 is a sectional view on the line 44 of Figure 2 showing the cover plate of the subframe removed, and

Figure 5 is a front view of the main frame only.

On the accompanying drawings I have used the reference character H to indicate a hose, F a frame and S a subframe. The frame F has an annular or spherical seat In and a plurality of ears l2 which may be secured to the hosing as by rivets M. The subframe S consists of a pair 2 of plates l6 and I8, the plate I6 having an annular or spherical wall 20 fitting with some play in the seat l0, and the plate I8 being secured to the plate It by screws 22.

The plates l5 and 18 have pintle seats 24' and 2 6 for the pintles .28 of hose guide rollers 30. Four of the rollers with eight pintles are shown and accordingly there are eight of the seats 24 and eight of the seats 26. These cooperate to form bearings for the pintles when th plates l5 and I8 are secured together face to face.

The plates l6 and I8 are also provided with pintle seats 32 and 34 to receive pivot pintles 36 which are pinned as at 38 in cars 40 of the frame F. Two of the ears are provided as shown in Figure l andthe spherical surfaces In and 20 are formed on 'a radius having its center located on the axis (Sf-the pintles 36 where it passes through the vertical center plane of the frame F.

The plate l8 may be considered as a cover plate and has upper and lower- extensions 42 and 44 which serve as stops to limit the pivotal movement of the subframe as illustrated in Figure 2. These stops engage the frame F.

Practical operation My swinging hose guide will normally assume the dotted position of Figure 2 when the hose is pulled straight through it and the rollers 30 reduce friction as the hose is swung to one side or the other or upwardly or downwardly. I have found that quite often it is required that the hose bend sharply downward or upward from the housing H and have therefore arranged for pivoting the subframe S so that it can swing as shown by full lines in Figure 2 when the hose is bent at a. sharper angle than usual.

The subframe is so constructed that it can be inexpensively fabricated and quickly assembled with the guide rollers 30 journaled in it and the subframe in turn journaled in the main frame. The pintles 36 as well as the pintles 28 are retained for rotation and oscillation respectively in the subframe plates when they are assembled by the screws 22.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope without sacrificing any of the advantages thereof.

I claim as my invention:

1. A hose guide comprising a main frame hav- 2'4, 3 ing a pair of ears on opposite sides thereof, a subframe pivoted to said ears and thereby Journaled on said main frame and having a hoseguide opening, said main frame having an arcuate seat and said subframe having" an arcuate outer wall movable in said arcuate seat.

2. A hose guide comprising an annular frame having a pair of ears, a subframe comprising a pair of plate members, means for securing said plate members together, saidplate members having pintle seats in their contacting faces and an, opening for a hose, and a plurality of rollers located in said opening, pintles for said rollers J ournaled in said pintle seats, said ears also having pintles extending into the pintle seats of said plate members.

3. A hose guide comprising an annular frame having a pair of ears, a subframe comprising a pair of plate members, means for securing said plate members together; said plate members having pintle seats in their contacting faces and an opening for a hose, a plurality of rollers located in said opening, pintles for said rollers journaled in saidpintle seats, said ears also having pintles extending into the pintle seats of said plate members, and said frame and subframe having complementary arcuate surfaces adjacent each other and formed on a radius from the axis of the pintles in said ears.

4. A hose guide comprising a main frame having attaching ears for mounting it on a housing, a subframe comprising first and second members, and having a hose guide opening, means for securing said members together face to face, said members having pintle seats in their faces and an opening for a hose, a plurality of rollers defining said opening and having pintles journaled in said pintle seats, said main frame also having pintles extending into the pintle seats of said members, and said frame and subframe having complementary arcuate surfaces adjacent each other and formed on a radius from the center of said last pintles.

5. A hose guide comprising a. main frame having attaching ears for mounting it on a housing, a subframe comprising first and second members, and having a hose guide opening, means for securing said members together face to face, said members having pintle seats in their faces and an opening for a hose, a plurality of rollers defining said opening and having pintles joumaled in said pintle seats, and means for pivoting said subframe on said main frame.

6. A hose guide comprising a main frame having attaching ears for mounting it on a housing,

a subframe comprising first and second members, and having a hose guide opening, means for securing said members together face to face, said members having pintle seats in their faces and an opening for a hose, a plurality of rollers defining said opening and having pintles joumaled in said pintle seats, said main frame also having pintles extending into the pintle seats of said members.

7. A hose guide comprising a main frame having attaching ears for mounting it on a housing, a sub-frame comprising first and second members, and having a hose guide opening, means for securing said member together face to face, said members having pintle seats in their faces and an opening for a hose, a plurality of rollers defining said opening and having pintles Journaled in said pintle seats, means for pivoting said subframe on said main frame, and extensions on said members to strike said main frame and thereby,

limit the pivotal movement of said subframe.
