against some overhead structure, or where,

the work is being conducted in the open Where it is not possible to so brace the bench.

A still further object of the invention is to produce a bench of the character described which is especially adapted for electricians.

use and with which it is possible to perform all of the operations ordinarily necessary in installing the conduits and the wiring in a building.

With the above and other objects in view which will appear as the description ,pro'

ceeds, the invention consists in the novel details of construction and combinations and arrangements of parts more fully hereinafter described and particularly appended claims.

Referring to the accompanying drawings pointed out in the forming a part of this specification in which like referencecharacters designate. like parts in all of the views:

Figure l is a perspective view of a work bench constructed in accordance with the present invention; 1

Fig. 2 is a top plan viewof the benc shown in Fig. 1; i

Fig. 3 is a vertical sectional view taken approximately on the planes indicated by the line 33 of Fig. 2, looking in the direction of the arrows; and, p V

Fig. i is a fragmentary sectional view of a slightly modified form 01 the construction. 1

removably receive the upper ends of the legs p 12 which may be secured withln the said sockets by means at the set sense or other which similar fastenings 13. The outer edge or perimeter of the table 10 is provided with an upstanding flange 14 which extends substantiallycompletely around said edgeand which serves to prevent couplings, elbows, unions and other similar pipe fittings from rolling off of the table duringits use. Secured upon one side of the table at a pointsubstantially opposite one of the apices is a pipeholding device 15, here shown as being one of the well known forms of chain vise commonly employed in pipe working. At or adjacent the apex, which is substantially opposite the vise 15, there is provided a pipe rest 16 which may take the form of an integral upstanding flange orwhich'if preferred may be made separately and rigidly secured to the said table in any suitable manner. The vise 15 and the rest 16' are of ordinary and well known construction and constitute no especial part of the present invention.

One of the integral sockets 11 which receive the supporting'legs 12,'here shown as being the right hand socket as viewed in Figs. 2 and 3, is enlarged somewhat and is provided with a recess 17, extending downwardly from the top surface of the table,

and the bottom of the said socket is provided with a pair of apertures 18 and 19 of different diameters which are adapted. to accom- 1 modate pipes of different. standard diameters which are in common use. For instance, the

aperture 18 may be of such dimensions as to freely receive a standard three-quarter inch pipe while the aperture 19 may be of the proper dimensions to freely receive a stand ard one-halfinch pipe; v

The right hand wallo't' the recess 17 is curved upon the arc of a circle as indicated at 20 and is provided with the substantially semi-cylindrical grooves 21 and 22, which are of substantially the same dimensions as and communicate with, the apertures 18 and 19 respectively. The socket 17 together with its apertures 18 and 19 and grooves 21 and 22 is integrally formed with the table 10 as. shown, and constitute means whereby pipesmay bebent to'produce elbows in the well knownmanner. That is to say, one end of a pipe which is to be bent is inserted 1 through one of the apertures 18 and 19 in a substantially vertical position, whereupon by applying force to the portion of the pipe projects upwardly above the stir-fate tell la the said pipe that it is necessary to produce a large number of bends in pipes at the same distance from the ends of the pipe lengths, as for example, where a large number of swltches are to be located, the same height from the floor. In order to facilitate the making of a plurality of bends at exactly the same distance from the end of the pipe sections, I have provided an adjustable stop beneath and adjacent the recess 17, which stop is here shown as comprising a downwardly extending rod or pipe 23, the upper end of which is threaded as at 24 into the under surface of the table 10, and which pipe or rod 23 carries an angularly and vertically adjustable finger or stop member which may be secured in any desired position by means of a set screw 26. As will be readily understood from'Figs. 2and 3 the finger or stop 25 may be adjusted vertically to any desired position relative to the bottom of the socket 11, and may be swung angularly beneath either of the apertures 18 or 19, whereupon it may be secured in such a position by means of the set screw 26. It is then possible to successively introduce any desired number of'pipesections into the particular aperture 18 or 19, being employed, with the lower ends of the said sections engaging the stop 25 and to produce bends in such pipe sections, all of which will be located at exactly the same distance from the ends of the pipe sections.

Itwill be-noted in connection with this pipe, bending socket that the recess 17 is provided with a bottom wall in which the holes or apertures 18 and 19 are formed cated at 28 to conform substantially with the outer surface of the standard pipes. To the left of the lug or member 27 I have pro vided means for receiving the end of the pipe section comprising an eye member 29 which may be threaded into a boss 30 provided on the table 10. The eye bolt or member 29 being in alignment with the member 27 it is possible to insert one end of a pipe section through the said eye member and by the exerting, downward force upon the projectin'g end'ofthe pipe section to produce a bend therein of any desired angularity. By then moving the pipe sect-ion toward the left as viewed in Figs. 2 and 3, and rotating it through an angle of 180 degrees or any other desired angle and again exerting a downward force upon the end of the pipe section projecting to the right beyond the member 27, a reverse bend may be formed in the pipe to produce a goose neck or S bend of any required angularity and dimensions.

Benches of this character are usually made as light as is consistent with the required strength in order that they may be readily transported from place to place and they are seldom heavy enough to be stable of their own weight under the forces which are commonly applied in bending, threading and litting of pipes. It is therefore, desirable and in many cases necessary to provide some means whereby such benches may be securely anchored in place to prevent them from tipping over when in use. I have provided a means whereby it is possible to securely anchor the present bench when it is being employed indoors where it is possible to brace the bench against a ceiling 01' overhead beam, and also when it is being employed out of doors or indoors where it is not possible to thus brace the bench against some overhead structure. To the end I have provided the table 10 as shown in Figs. 2 and 3 with a boss having a pair of holes 36 and 37 extending therethrough. The hole 36 is threaded and is adapted to receive the lower threaded end 38 of a stud 39, the upper end of which is enlarged to provide a shoulder 40 which engages the upper surface of the boss 35 and prevents the stud from passing entirely through the holes. Said stud 39 is also provided with a transverse handle or bar 41 by means of which it may be rotated andthe extreme upper end of the stud is provided with a flange 4.2 which is surmounted by a reduced boss or projection &3 adapted to be received within a section of pipe 4% which is cut to a length suitable to extend upwardly to engage the ceiling or an overhead beam.

In use the pipe section 44 will be positioned substantially as illustrated in dotted lines of Fig. 3, whereupon by rotating the stud 39 by means of its handle 41, the said pipe section may be forced upwardly against the overhead structure thereby securely bra-cing the pipe bench in operative position.

Where the work is being conducted in the open or some place where it is not possible to brace the bench against an overhead structure, the stud 39 is removed from the hole 36 and placed in the hole 37 which latter hole is not threaded and is of a diameter suificient to permit the threaded end 38 of the said stud to freely work therein. In this case, a nut 45 is threaded upon the lower threaded end 38 of the stud 39 which nut is provided CPI with an eye member 46 to which is secured one end of a chain or cable 47, which chain or cable may be passed around a plank or beam 48 and have its other end brought upwardly and secured to a projecting pin 49, also carried by the nut 45. By rotating the stud 39 by means of its handle or pipe 41, the nut may be moved upwardly due to its screw threaded engagement with the said stud, to tightly clamp the beam or plank 48 against the lower ends of the legs 12 which support the table.

From the construction just described it will be readiy apparent that the bench may be securely anchored and rendered substan tially rigid under all operating conditions, whether the work is being conducted indoors or out of. doors.

i In Fig. 4 I have illustrated a slightly modified and preferred form of construc-. tion of the stud 39 for securing the bench against displacement in which it is necessary to provide only one aperture such as 36 in the table 10. In this case, a yoke mem ber 50 is swivelly mounted upon the lower reduced end 51 which is provided beneath the screw threads 38 of the stud 39 which yoke or collar 50 carries the chain 47 which is employed for fastening the bench to a plank or beam such as 48. The operation is substantially the same however, when the chain 47 and plank 48 are being employed, insofar as the bracing of the bench is concorned as when the upwardly extending pipe section 44 is employed. In otherwords, by turning the stud 39 it threads in the aperture 36 to move upwardly and downwardly whether the chain 47 or the pipe 44 is being used.

It will of course, be understood that the pipe 44 is not ordinarily employed when the chain 47 is being used and vice versa.

It will thus be seen that the present invention provides a work bench for electricians and other mechanics who work with pipe which may be readily set up in an exceedingly rigid position either indoors or out of doors and. which provide means whereby large number of bends may be produced in pipe sections of exactly the same distance from the end of the section .in each case. Also that means is provided for producing reverse bends in pipe sections and that the provision of the flange 14 extending substan tially entirely around the periphery of the table will prevent the pipe fittings from rolling oil of the bench and becoming lost.

lVhile one form of the invention has been thus illustrated and described, it is obvious that those skilled in the art may vary the details of construction as well as the precise arrangements of parts without departing from the spirit of the invention and therefore it is not wished to be limited to the above disclosure except as may be required by the claims. 7
