PIPE-CUTTERS WORK-BENCH.

Specification of Letters Patent.

Patented May 15, 1917.

Application filed November 4, 1915. Serial No. 59,548.

To aZZ whom it may concern:

Be it known that we, CLYDE H. LOUGH- moon and Hon Ann R. LoUoHnIDGE, citizens of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Pipe-Cutters \VorlrBenches, of which the following is a specification.

Our invention consists of an improvement in a work bench or frame adapted for the cutting of pipe, rods or the like, and has in view to provide a support whereby the piece to be cut may be rigidly mounted and secured at each side of the operative section of the cutting tool, whereby the several pieces will be fixedly held after the cutting operation. The invention also has in view to provide a simple, strong, convenient and economical holding frame having the advantages noted, and various other advan tages and improvements, as shall be more fully hereinafter described.

Referring to the drawings showing one preferred embodiment of the invention,-

Figure 1 is a view of the supporting frame in side elevation, showing a section .of pipe in position for the cutting operation.

Fig. 2 is an end view of Fig. 1.

The end portions of the frame are formed of vertically arranged legs or standards 2,

2, at each end, of bar or structural metal, between which at the upper portion are the,

depending brackets 3, 3, connected with supports 2 by bolts or rivets, as indicated at 4, a cross bracing strip or cap member 5 belng also connected with said parts, whereby to rigidly join the several members.

The supports 2 diverge downwardly toward the base, and are connected at the corners of the frame, at each end, with the diagonally arranged brace members 6. These brace members cross each other at the mid dle portion of the base of the machine, one being offset from the other, as indicated at 1 7 and by this means it will be seen that the base of the frame is strongly braced and reinforced, while also providing additional floor contacting portions.

The upper supporting members for the pipe itself consist of two longitudinally arranged bars 8, 8, in alinement with each other, separated by an intervening clearance space 9 at the middle portion of the frame for clearance of the cutting tool in its operation around the pipe 10. Bars 8, as shown, are of T-section, thereby providing by the flanges 11 an upper fiat base, upon which are mounted the supporting and holding devices for the pipe 10. These comprise anvil members or supports 12 and vise members 13 respectively, one of each being preferably utilized at each side of the middle clearance or operating space.

The web of the T bar 8 is embraced by the lower terminals of the stirrup members 3, as indicated at 14, said members being bolted thereto, as shown, whereby the parts are fixedly connected in position. Connected to the inner ends of bars 8, by terminals 15, bolted or riveted thereto, are the middle brace or supporting members 16, 16, of general V shape, the lower terminal whereof is fixedly secured to the cross-braces 6 at their crossing juncture 7, thus further reinforcing and bracing the structure.

Laterally arranged brackets 17 are secured to the leg members 16, as indicated, for holding any tools or implements used in connection with the work, and a drip pan 18 supported by lugs 19 on pedestals 16, serves to collect any oil or cuttings which may fall during the work.

, Additional cross braces 20 are preferably employed to insure rigidity of the construction.

The base, as thus made, is also preferably provided with adjusting set screws 21, at each corner and also at the middle of the structure, permitting the frame to be adjusted to any inequalities or unevenness in the floor, so as to insure its stability and horizontal position.

Each bar 8 is provided with a series of holes 22 through its web portion, by which the base 18 of the vise may be fixedly held by bolts or set screws 23, extending through the terminal flanges of the vise base, as clearly shown in Fig. 2. By this means the vise may be located at any desired position and there held, at each side of the middle operative position. The anvil supports 12 are similarly mounted on the flanges 11 of bar 8 and are adjustably set and secured, each. of said members having upper recessed bearing faces for receiving the pipe 10.

Each vise 13 is provided with a coacting companion jaw 24 which is clamped upon the pipe by a tightening nut 25 engaging bolt 26 extending upwardly at one side of the vise, as will be readily understood.

As thus constructed the frame is capable of receiving and fixedly holding a section of pipe, with the severing point corresponding to the clearance space 9, so that the pipe cutter may be applied and rotatably operated, in the well-known manner, or in any similar manner, depending on the particular construction of the cutter itself, around the pipe, either to completely sever it, or to partly cut it, as in the making of annular grooves, or both.

The clearance opening 9 provides ample space for the operation of the tool; the holding of the pipe in the vise at each side of the clearance opening positively insures the positioning of the pipe, both before and after the cutting operation, so that the severed part will not fall or bend, thereby enabling the workman to effect a complete clean out, without burring or ragged edges.

The table as thus constructed is comparatively light and portable, and may be readily transported and set up in any available location for utilization, as in connection with the various circumstances of pipe fitting at the point of the work of installation.

While it is particularly adapted to the work intended, it may also be used for the cutting of solid bars or any other similar work, and the device may also be changed or varied in construction or different details by the skilled mechanic to adapt it to the particular kind of work or material without departure from the scope of the appended claims.

What we claim is:

1. A pipe supporting table having a visesupporting bar at each side of an intervening working position, a longitudinally adjust'able vise mounted on each of said bars, means for rigidly supporting the bars at each end, and additional supports for the inner ends of the vise-supporting bars providing an intervening clearance space.

2. In a work bench or frame of the type disclosed, the combination with a support ing bench having a securing device, of a similar bench spaced beyond the end of said first named bench and provided with a securing device, the securing devices being movable toward and away from each other independently of their supporting benches.

3. In a work bench or frame of the type disclosed, the combination with a supporting bench having a securing device, of a similar bench in alin ement therewith spaced beyond the end of said first named bench and also provided with a securing device, a vertically arranged standard for each of said benches, vertical supports connecting the adjacent ends of said benches and providing an intervening clearance space, and

bracing members connecting the bench standards and said vertical supports.

4. In combination, an interrupted twopart support terminating at each side of an intervening clearance space, a mounting frame therefor having rigidly connected bracing devices, and longitudinally adjustable supporting and securing devices mounted on each of said main supports.

In testimony whereof we hereunto our signatures in the presence of two wit- IIBSSQS.
