STEADYING BLOCK ron rHEEAm-Ns MnoiiINEs AND THE LIKE.

. vOriginal application My invention relates to machinery and primarily to'that type known as a pipe or bolt threading machine.

The primary object of my invention is to provide a new and improved type of steadying block or work rest for machines of this character.

A further object is to so construct said s'teadying block that it may be readily and easily manipulated for operative position and engagement with various sizes of pipe, which may be threaded in the machine.

Another object is to providea novel form of guide means for the steadying block which permits ease of manipulation and rigidity of construction.

A still further object is to provide the work engaging surfaces of the steadying block with removable plates whereby ready renewal of the engaging faces may be made when necessary.

Other objects and advantages in details of construct-ion and operation will be apparent as the description proceeds, reference being had to the accompanying drawings wherein like reference numerals indicate like )arts. I This application is a division of my application, Serial No. 693,604, filed February 18, 1924, for pipe threading machines.

In the drawing N The figure is a back view of a pipe threading machine head, showing my improved steadying block mounted thereon in, operative position.

I have indicated by the reference numeral 1, a head or thread cutting die rigidly mounted upon the carriage 2, which is provided with journals 3 and 4, adapted for arm 7 on its pivot bringing the cutting offsliding engagement with the ways (not shown) of the threading machine. An aperture 5 in the head 1, permits the threaded end of the pipe to project through the head for purposes ofreaming and cutting off.

Pivoted at 6 on the lower part of the head 1, is an arm 7 carrying at its upper end a cutting off (.001 8.- A shaft 9 having threaded engagement in a swivel ball, 10, mounted in the arm 7, operates through the medium of the handle or hand wheel 11 @to rock the tool 8 into or out ofengagement with the extended end of the pipe. (not shown) which projects through the opening in the head.

filed February 18, 1924, Serial No. 693,604, and in Canada March 20 1924. Divided and this application filed March 25, 1925. Serial No. 18,249.

Also pivotally mounted as at 12 on the arm 7 is a reaming tool (not shown).

The handle 13 provided with the hand grip 14 provides a locking and operating means for the mechanism of the die head (not shown). Details of these elements just described are to be found in applicantsparent application above mentioned, of which this is adivision.

Mounted in bearings 15 and 16 rigid with the head 1,' is a screw threaded shaft 17 provided at its outer end with a hand wheel 18.

Mounted upon this shaft 17 and having 1119; surface of the projecting pipe end.

I It will be understood of course that by manipulating the hand wheel 18, the V plates 24 carried by the extension 20 may be caused to move downwardly into engaging positibn with pipe of any diameter which may be projected through the aperture 5.

The operation of my device is as followsz-After a section of pipe has been threaded in the head 1, the carriage 2 is rocked forward on the threading machine sufiiciently far to permit the threaded end of pipe to extend or project through the opening 5 for reaming or for cutting off the threaded end. In order to steady the rotating pipe for the reaming or cutting off operation, the hand wheel 18 is manipulated to move the sleeve 19 with its extension 20 downwardly until the face plates 24 carried in the V shaped portion of the extension, engage with the pipe, whereby the same may be steadied in its rotating movement while the reaming or cutting off operations are taking place. Immediately after such operation, the operator manipulates the hand wheel 18 in the opposite direction to withdraw the steadying block from the pipe at which time the pipe may be removed from the machine.

When the facing plates 24 become worn hy continuous use and frictional engagement With the pipe, they may be readily removed ind replaced with new plates.

It will be apparent to those skilled in the art, that the various elements described and shown in the accompanying drawing are of broad application and susceptible to a variety of forms and uses on machinery requiring steadying blocks, without departing "from the scope of the invention. I do not limit myself therefore to the exact structure shown and described other than by the appended claim. 'I claim:

In combination with a die head, having an opening therethrough, bearings on'said head projecting laterally from one face thereof, a threaded shaftrotatalole in said bearing, a threaded sleeve encirclingsaid shaft adjacent said tace, and adapted to travel on said shaft, and a single laterally extending flange on said sleeve adjacent to and parallel With said face, provided with a V-shaped steady ing surface adapted to move over said opening, aguide slot in the free end of said flange parallel with said shaft and a pin carried said face projecting through said slot.

LESLIE S'. HALL.
