Application July 29, 1946, Serial l lorfiil'ulll'l I I I I This invention relates to clamps designed primarily for use in handling fire hose.

It is a fact well known that fire hose, while in use, are very difficult to handle while being carried upwardly from place to place, this being especially true at such times as water is turned on. The pressure of the water in the hose tends to move the hose abruptly from the position in which it is being supported and this abrupt movement frequently has resulted in injury to persons handling the hose as well as pulling of the hose away from the position to which it has been carried.

An object of the present invention is to provide a clamp which can be applied readily to fire hose and which, when in position thereon, will allow the hose to be easily conveyed either by hand or by hoisting rope to the point desired, there being means on the clamp for engaging a ladder, window-sill or other structure so that when the water is turned under pressure into the hose, the nozzle will not be jerked from the point where it has been placed and injury to the users or displacement of the nozzle will not result.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain, novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred forms of the invention have been shown.

In said drawings Figure 1 is a front elevation of one form of clamp embodying the present improvements.

Figure 2 is a. top plan view thereof.

Figure 3 is a side elevation.

Figure 4 is a front elevation of another or simplified form.

Figure 5 is a side elevation of the structure shown in Figure 4.

Referring to the figures by characters of reference, I designates the body of the clamp which, in the form shown in Figure 1, includes side arms 2 and 3 joined by a top portion 4 which, in turn, has a hand hold 5 whereby the clamp can be conveniently carried, and also has an opening 6 in which a hoisting rope or the like can be fastened. This top portion 4 can also be provided with a bracket I carrying a roller 8 whereby, while the clamp is being moved upwardly 1 Claim. (01. 248-45) with a hose nozzle attached thereto, the roller can travel along a guiding surface, thereby re ducing. friction to the. minimum. 1 I

Arm 2 has its lower. or free end offset in the directionof arm 3 as shown at 9 and slidably mounted in the other arm 3 is one end of a. latch pin I 0, the free end of which normally rests on the offset portion 9. A spring H can be carried byarmd for exerting a constant pressure against one end: of the latch pin so as tohold the latch normally positioned adjacent to the lower ends of the arms 2 and 3.

Arm 3 has a laterally extended loop I2 at its lower end which is rigid and fixed relative to the arm. This loop is proportioned to embrace and lit securely about a portion of a hose nozzle so as to be a part thereof. Opposed gripping springs are carried by the loop or clamp I2 as shown at I3 and are adapted to press yieldingly against an inserted hose or hose nozzle "and thereby hold the clamp securely to the hose or its nozzle.

In practice the hose to be handled is inserted into the clamp l2 where it will be gripped by the springs I 3 so that the hose thus cannot be pulled away from the clamp. Thereafter a. hoisting rope or the like secured in the opening 6 can be employed for pulling the hose upwardly along a ladder or a wall, this movement being facilitated by the anti-friction roller 8. When the structure is brought to a desired elevation, the body I can be placed astride a ladder rung, a window sill, or other support, where it will be held securely by means of the safety latch pin which is adapted to open upwardly to permit the body I to be placed in position on its support.

With the structure thus in place, it will be apparent that when water under pressure is turned into the engaged hose, the hose will not be pulled away from the position to which it has been brought. Consequently the danger of injury to persons handling the hose or the danger of pulling the hose away from the position to which it has been brought, is eliminated.

Obviously various modifications of this structure can be made within the scope of the present invention. For example, and as shown in Figures 4 and 5, the body I4 of the structure can be in the form of a stem or shank having a support engaging hook I5 at its upper end equipped with a, latch l6 pivotally joined to the body I and adapted to close the hook against withdrawal from a support on which the hook is mounted. Combined handles and runners in the form of spaced loops I! can be carried by and extended longitudinally of the body l4 so that as the structure with hose connected thereto is pulled or carried upwardly, the movement thereof along a wall, ladder or the like, will be expedited.

In this modified form the hose engaging structure is in the form of a lazytongs l8 pivotally joined to the lower'end of the body 14 and provided at the lower ends thereof with opposed jaws I9. These jaws are so proportioned and located that when they are moved toward the body I4 they will shift away from each other a sufficient distance to allow a hose to be inserted between them. Thereafter by pulling the lazytongs upwardly, the jaws will grip the hose. Thus the hose will be held securely to the structure while bein pulled upwardly and whenever water under pressure is turned into the hose, v l

the resultant pull will not disengage the hose from the clamp. Therefore, if the hook is in engagement with a ladder, a window sill, or

and be supported by a supporting element, said structure having an opening for receiving the supporting element, means normally closing said opening for holding the structure in engagement with a supporting element, and movably mounted hose ripping and supporting means carried by the structure, said hose gripping and supporting means including a hose embracing loop rigid with one end of the structure and proportioned to permit free sliding movement of a hose therethrough, and spring means on the loop for gripping the engaged hose, said spring means being adapted to yield when a hose is moved through the loop in one direction, and to engage the hose against movement in the other direction.
