United States Patent DEVICE FOR FACILITATING: PREFABRICATIO OFSDIL PIPE UNITS George'E. Kjellberg, Lake Worth, Fla. Application August 14, 1-952, Serial.No. 304,3 61= 6 Claims. (Cl; 29-287) maintained in avertical" position for packing and leading.

Another object of this invention is to provide a device for holding soil pipe units to be joined in vertically level' relationship at said joinder for packing andleading.

Another object ofthis invention is to provide a device fonuse in-pre fabricating s'oil pipeunits having only two axes ofmovementbut which assumes any'desiredangular position.

A further object of this invention is to provide a device for use in pre-fabricating soil pipe units with adjusting means to accommodate any size soil pipe and different sizes of soil pipe units in a single pro-fabrication.

The foregoing and other objects and-advantages of this invention will. be more apparent from studying the following; specification together with the accompanying drawingsgiorming arp'art-thereoflwherein:

In the drawings, wherein like members are; givenithe same reference numeral. a support member 1, which. may be a buildinglwall, separate wall, side of a vehiclebodw or any other suitable supportmember, has secured thereto a horizontally extending bushing or hearing. member. 2; having an open end 3 and means 4 securingthe bushing 2 to the support member 1. The means 4 of securing the tapped aperture provided in wall of said collar 2,724,175 Patented Nov. 22

' 2 bushing 2 to the support member 1 preferably a as: plate which is welded to the bushing2, preferably a length of pipe; and welded or bolted to the support member'l. The securing means 4 may equally be a flanged portion of a pipe serving as a bushing, which flanged portion is welded or bolted to the support member" 1.

Positioned in the bushing 2 is a spindle 6 mountedin amanner to freely rotate therein but preventing longitu' dinal displacement. This spindle 6 may be a solid rod,- but it is preferably a length of pipe having heavy Wallsections to provide adequate strength with minimum weight. It is maintained against" longitudinal displace ment but permitting free rotation bYproviding an annular groove or recess 7 in the spindle 6 into Whi'cli a plurality of bolts 8 extend but do not abut. These bolts 8 are positioned in any suitable manner; such as welding. in apertures 9 in the bushing 2, or by threaded engage ment with the apertures 9 which have been tapped, pro: vided in thebushing 2, in alignment with the annular groove 7. V

The bushing 2 has a plurality of inwardly tapering apertures Il provided in the top portion thereof and" positioned in a longitudinal line along the bushing; The spindle 6 has a plurality of tapered apertures 12 pro vided therein at dilferent degrees around the periphery thereof and in alignment with the other corresponding tapered apertures ll' i respectively, it being illustrated that thetwo tapered

apertures

11 and 11 in the bushing. 2may be combined into one

aperture

11 and 11" because the corresponding apertures 12*" and 12ir1' the spiri'dlefi intersect; the same is true of

apertures

11 and 11% maybe"- combined due to the fact that apertures 12* and12 i11 tersect. A- tapered pin 14 inserted through align'edfa'nd registering apertures Il andlF- respectively 10ers the spindle against rotation. The open end 3 of the bushing 2 is provided with a circle scale 16 therearoun'd dividing the periphery into degrees and fractions thereof; and the spindle 6 has a pointer 17 mounted thereon and having the pointer end thereof positioned over the scale 16. When the tapered pin 14- incooperation with the apertures Il and H is not used to'lock the spindle 6" in a pro-determined degree of rotation not provided for by the apertures, the spindle 6 is rotated to the de sired degree and locked in position by' a hand screw 18 threadedly engaging a tapped aperture 19 in the bushing 2' until! the end of the. screw 18 frictionally secures the spindle (i against rotation. When the tapered pin 14 is used, with apertures II and 12 aligned in true vertical. position the scale 16 reads 0; with apertures 11 and. 11 and 12 aligned the scale reads 45, and with apertures 1 1 and. 11 and" 12 aligned the scale reads 313 the

apertures

12 and 12 being 45 from vertical 12 and positioned on oppositesides thereof; with apertures" 11'? and 12 aligned= the scale reads with apertures. 1'19 and" 12 aligned the scale reads 270; with apertures f1 and 111 and 12 aligned the scale reads and with apertures 11 and" 11 and 12 aligned the scale read s 225; and with

apertures

11 and 12 aligned the's'cale reads 180. The arrangement of these'cooperating apex t-ures t'oprovide'means to lock the spindle in each 45f" oi rotation is attributable to the fact that soil pipe fittings are designed with limited fewexceptions which are now practically obsolete, for joint-s at 4 5" and. multiples" thereof angular displacement. The spindle terminates in a clamp means, here illus trated as cylindrical collar, bearing or bushing rhemhei 21." having a hand: screw bolt 18 'threadedly engaging s cylindrical support column or shaft 22, preferably a length of pipe, is inserted in the collar bearing 21 and? frictionally held in place by turning: the hand screw bolt 18 until it securely abuts the shaft 22 clamping it against the side wall of the collar 21, by releasing the pressure of the hand screw bolt 18% the shaft 22 may be rotated or moved longitudinally in the collar 21. To p revent longitudinal movement of the shaft 22 in the collar 21, with the pressure of the hand screw released,

cylindrical thrust bearings

23 and 23 are positioned around the column and on opposed sides of the collar 21. The

thrust bearings

23 and 23 are secured to the column 21 by

hand screw bolts

18 and 18 engaging threaded apertures in the

bearings

23 and 23*, respectively. When the device is used in less than 180 rotation of the spindle, the bottom thrust bearing 23 can be eliminated; but the device is designed for 360 rotation of the spindle 6, and in such utility both thrust bearings must be used.

A work support arm 26 is releasably and slidably mounted on the shaft 22 by means of a cylindrical collar 23 secured to said arm 26 and having a. hand screw bolt 18 threadedly engaging a tapped aperture in the collar 23 The Work support arm is preferably a length of pipe. Slidablymounted on the arm 26 is a collar 24 having a hand screw bolt 18 threadedly engaging an aperture in the collar, and having the same general cont struction as the other collars having hand screw bolt means for releasably clamping to a member. Secured to the collar 24 in any suitable manner, such as welding or cast integral therewith, is a pipe support member 27. This member 27 is preferably conical-shaped to positively center and support various pipe of different diameters. Another work support arm 26', with collar, hand screw bolt, and pipe support member 27' may be positioned on the shaft 22 opposed to the first pipe support member 27 to support pipe from that end of the column and also to reinforce the first pipe support 27 when Y fittings are joined in the units of soil pipe fabricated. This top pipe support 27' assembly can in many cases be eliminated.

I Slidably connected to the shaft 22, on opposed sides of the collar bearing 21 are pipe aligning assemblies. These assemblies comprise a cylindrical collar 23 having a hand screw bolt 18 threadedly engaging a tapped aperture .therein to releasably clamp the column 22, a V-shaped member 28 having the vertex thereof rigidly secured to the collar 23 by welding or other suitable means and positioned parallel to the transverse axis of said'cylindrical collar. Stated differently, the plane of the V-shaped. member is perpendicular to the longitudinal axis of the shaft 22, a bar 29 is pivotally mounted by a pin 30 to one leg of the V-shaped member 28 and is releasably fastened to the other leg of the V-shaped member 28 by removable pin 31 to form an isometric triangle. A bolt 32 threadedly engages a tapped aperture 33 positioned in the bar 29 at a point bisecting the bar g9 and directed toward the vertex of the V-shaped mem- There is provided an insert V-shaped member 34 having channels 35 formed in the legs thereof adapted to receive the inside edges of the legs of the -V-shaped mem- .Iber 28. This insert member 34 is so constructed and arranged that when one size pipe is being used and a joinder therewith of a smaller size pipe is desired, the insert positions the smaller size in coaxial or concentric alignment with. the large pipe. The insert member 34 is equally of value in aligning pipes of different diameters when the converse relationship exists.

In operation the device is quite simple, efficient, durable and economical. With the tapered pin 14 inserted the tapered

apertures

11 and 12 the spindle 6 is held s taltienary and with the hand screw bolt 18 clamping the'shaft 22 in vertical position, a length of soil pipe A is. positioned on the pipe support 27, which has previously been adjusted for the correct diameter pipe, and a pipe aligning assembly is positioned in a manner such that the top section of the pipe A rests in the V of the V-sh'aped member 28 which is clamped by means of the hand screw bolt 18 to the shaft 22.' The pivotally mounted bar 29 is fastened in place with the removable pin 31 and the bolt 33 turned to abut the'pipe A; An-

other seetionof pipe B is positioned in the bell section of the pipe A, these sections of pipe are then packed and molten lead poured in the bell section according to usual standard procedure for packing and leading a vertical joint. When sections are to be added to the angular branch of a Y section of pipe in which the plane of the longitudinal axes thereof are'parallel to the plane of a transverse section of the spindle 6, the pin 14 is removed and the spindle rotated 45 deg. from vertical in the direction opposite the angle of the Y pipe. For illustration, if the angle of the Y is to they right the spindle 6 is rotated to the left and the tapered pin 14 is inserted in the then aligned

apertures

11 and 12 locking the spindle 6 and positioning the angular section of the Y pipe in vertical position for vertical packing and leading.

When T or Y sections of pipe have longitudinal axes in a plane perpendicular to the plane of a transverse section of the spindle 6, and it is desired to pack and lead the angular section or leg thereof, the hand screw bolt 18 clamping the shaft 22 in the collar bearing 21 is released and the shaft 22, with the pipe supported and heldin position by the supports 27 and 27' and align,- ing assembly V-shaped member 28 and related parts, is rotated up and back towards the support member 1 the desired degree until the angular section or legis vertical, the hand screw bolt 18 is tightened and a vertically packed and leaded joint is made in the usual manner.

It is thus illustrated and described that the device of this invention enables one to prefabricate soil pipe units with a vertical joinder, which is a saving of time and material. It has been calculated that there is a saving of one-half pound of lead per joint in vertical joinder over horizontal or substantially horizontal joinders. The saving in time is obviously much greater than the saving in material, because vertical joinders are simple gravity flow pour procedures.

In order to prevent the work support member 27 from rotating on the work support arm 26 when the hand screw bolt 18 is released, a longitudinal groove 36 is provided in the lower section of the arm 26 to receive the end of the hand screw bolt 18. The groove 36 is so constructed and designed in cross-section to permit only clearance tolerance between the bolt 18 and side walls of the groove, i. e., the cross-sectional dimension of the groove is slightly more than the cross-sectional dimension diameter, of the bolt.
