"f igure fiiliustratesa similar An object of the"invention:isftofprovide a clamping means having a fle k i ble element which is caused to embrace the pipe -sections, the said devicebeing provided with rneans for tensioning 1051 a the pipe embracing element so that theis aid pipe" c'fnovelrneans are ng'means is wound different positions sections are, held assembled, provided bywhichth tensiom on a drum or shaft and'held at A further object of the invention is to provide a pipe holding instrumentality and to associate it with a manually rotated shaft on which the tensioning member is wound; the said shaft being also provided with ratchet wheels engaged by a pawl, which pawl is under tension of a spring that automatically causes the engagement of the pawl with the said ratchet teeth.

It is furthermore an object to provide a housing for the tensioning means, the ratchet of which is accessible through the housing so that it may be manipulated after the device is fully assembled.

It is a further object of this invention to provide a pipe holder of the character indicated having a plate adjustable on the frame, the said frame having graduations thereon to indicate the width of a pipe to which the device is adapted for use, the said plate having an anchorage for a flexible pipe embracing element, which element is wound on a shaft for regulating the tension thereof on the pipe sections which are embraced by the work holder.

A still further object of the invention is to produce a work holder of the character indicated which is efficient and satisfactory in use and comparatively inexpensive to manufacture and maintain.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application, wherein like characters denote corresponding parts in the several views, and in which: f,

Injt esedrawings, i denotes a frame having iiies- 2-, on a rate a rs sueablez wfrnere is a fflaj'nge dhaving gradiiatieiwnumbers thereon any of the numbers of the graduations so that proper positioning of the plate may be attained. The frame has a slot 6 therein in which a bolt I is slidable, the said bolt being engaged by nuts, such as 8, above the plate and below the frame, so that by adjustment of the bolt the plate is clamped in different positions of adjustment. The outer end of the plate has a lug 9, for a purpose to be presently described.

The sides 2 of the frame are cut away. as at ID, to form bearings for a shaft II and said shaft being rotatable in the bearings has a flexible clamping element l2 wound thereon. The said clamping element is caused to embrace pipe sections l3 and I4 in the manner shown in Figure 2, and when the shaft is rotated, the clamping element is wound on the shaft so that the tension of the clamping element is caused to hold the pipe sections assembled; it being understood that the end of the clamping element has a ring or yoke is which is engaged by the 111g 9 so that when the clamping element is wound on the shaft it will be retained assembled with the pipe sections as shown in Figure 2.

Ratchet wheels l6 and I! are also mounted on the shaft l I, and the teeth of these ratchet wheels are engaged by a detent or pawl l8 which is mounted on a pivot IQ of the frame member carried by brackets, such as Illa. The pawl bracket shaft may be rotated and when the proper tension has been attained, the pawl will hold the parts in their adjusted positions. Preferably, the shaft is rotated by a knob or handle 22 secured to the shaft and this knob or handle is externally of a housin which comprises the two

sections

23 and 24, the former being superimposed on flanges, such as 25, of the frame, whereas the latter is underslung on the frame, and these two housing sections are held assembled on the frame by fastenings, such as bolts, 26, as those skilled in the art will understand.

The housing section 23 has an opening-through which the outer end of the pawl is accessible, or through which it may project so that it may be pressed by an operator for the purpose of disengaging the pawl from the ratchet teeth. It will thus be seen that the operating parts of the device are accessible from points externally of the housing and that adjustments may be made to accommodate pipes of difierent sizes or dimenslons.

I claim:

1. A pipe clamp comprising a frame, a member slidable on a portion of the frame, means for holding the said member in different positions of adjustment, a lug on the outer end of said member, a flexible pipe embracing element having a connection for anchorage to the lug, a shaft on which the pipe embracing element is wound for regulating its tension on the pipe sections, means for holding the shaft in different positions of adjustment, ahousing for the shaft and said means, and a hand operated element on the shaft externally of the housing for rotatin said shaft.

2. A pipe clamp comprising a frame, a member slidable on a portion of the frame, means for holding the said member in different positions of adjustment, a lug on the outer end of said member, a flexible pipe embracing element having a connection for anchorage to the lug, a shaft on which the pipe embracing element is wound for regulating its tension on the pipe sections, means for holding the shaft in different positions of adjustment comprisin ratchet wheels on said shaft. a spring pressed detent engaging the ratchet teeth for holding the shaft at different positions of adjustment, a housing for the shaftand parts associated therewith, and a hand operated element on the shaft externally of the housing for rotating said shaft.

3. A pipe clamp comprising a frame, a member slidable on a portion of the frame, means for holding the said member in different positions of adjustment, a lug on the outer end of said member, a flexible pipe embracing element having a connection for anchorage to the lug, a shaft on which the pipe embracing element is wound for regulating its tension on the pipe sections, means for holding the shaft in different positions of adjustment, and a hand operated element on the shaft for rotating said shaft.
