ArPAnA'rUsron FORMING PIPE-JOINTS.
Application filed December 23, 1918.-
l b all Iii/L07)? it may come m:
lie it known that .1, DE Wi'r'r l1. l lyii'r'r, a citizen of the United States, residing at Go lumbus, in the county of Franklin and State of Ohio, have invented certain new and use ful Improvements in Apparatus for Forming Pipe-Joints, of which the following is a specification.
This invention relates to an apparatus for forming pipe joints such as disclosed in my patent granted November 12, 1918, No. 1,284,334.
In the present invention, it is my main object to provide a structure which is adjustable to accommodate pipes of varying diameters, in other words, to make a single form structure accommodate a number of sizes of pipes. To do this, I provide a plurality of sections each in themselves formed of a plurality of members flexibly joined together, in combination with means for detachably uniting said sections at various )oints to ada it the assembla e to oi )es a l varying in size.
It is also an object of the present invention to provide a structure of the class described wherein the form may beadjusted to accommodate anurnber of pipes of varying standard size in combination with a second adjustment to adjust the assemblage to such slight variations in size as occur in the so called standard sizes. These lattervariations may result from a number of causes, notably variations in shrinkage during. the
manufacture of the pipes.
The preferred embodiment of my invention is shown in the accompanying sheet of drawings wherein similar charactersof reference designate corresponding parts and wherein- I Figure 1 is a View in side elevation showing my improved apparatus applied to a P 1 Fig. 2 is a top plan view on an enlarged scale of the upper portion of the structure shown in Fig. 1,
Fig. 3 is an enlarged sectional view taken through one edge of "the flexible members showing the manner in which the various sections are joined to adapt the form to various standard sizes, and
Fig. 4; is a horizontal longitudinal section taken through the structure shown in Fig. 1.
I have chosen to illustrate my invention in connection with the bell end 1 of a pipe 2 Specification of Letters Extent. Patented Sept. 14, 1920.
Serial No. 267,924. 7 j
and the spigot end 3 of the pipe 4. In using the form, the bell and spigot ends of the pipes are assembled as shown in Fig. 1 and the form then applied thereto in the manner shownin Fig. 1. Cement or any other suitable material is allowed to run around the form to suitably pack the same'as is illustrated at 5.
The form: itself is in general constructed after the manner described and claimed in my patentreferred to andcomprises, in the present instance, two sections (5 and 7.
each section being in itself formed of a plu' rality of form members '8 of short length and flexibly joined together by means of the flexible cables shown at 9. The present embodiment shows the various members 8 as being provided w1th struckout portions 10 adjacent each longitudinal edge through which the cables 9 are laced and by a hammer blow upon these portions 10 after the cables have been properly applied, they may be rigidly held in connection with each of the various form members. trated in Fig. 1, the section 6 is constituted of a plurality of form members 8 ending with that designated 11 at one end and car ries an upstanding plate 12 at its opposite end which cooperates'with a portion 13 to form a funnel through which the sealing material may be poured. This portion 13 forms one end of the section 7 whose opposite end terminates with'the member Li and the clamps 15, the latter being shown particularly in Fig. The funnel portion 13 is mountedupon a form member 16 which is'adjustably carried upon the corresponding end of the section 7 to float as is illustrated in my former patent, or, if desired,- this latter 'form 16 may be entirely free of the remainder of the section 7 and be placed in position by hand. It is essential that one end of one of the sections 6 and- Tshould be provided with a small adjustment and this may be accomplished by mounting the funnel portion and its supporting member as described when used in combination with the tightening clamps 17. These tightening clamps are pivotally mounted adjacent the end of the section 7 as is shown at 1.8 and, it is to the member carrying these clamps that the cables 9 are rigidly secured at one end. The member carrying the tunnel portion 12 on the end of the opposite section 6 is provided As is illuswith a pair of upstanding lugs 19 with which the ends of the adjusting screws 20 threaded through the clamps l7 abut. Like wise the cables 9 of the section 6 also end with the form member carrying a funnel portion 12. Thus, when the form is placed about the meeting ends of a pair of pipes, it may be tightened in position by means of the screws or bolts 20 and in this tightening operation, the form member 16 carrying the tunnel portion 13 telescopes beneath the end form member of the section 7 a distance corresponding to any variations in the circumference of the so called standard pipes. By this arrangement, this small adjustment member etiected and at the same time the funnel portion will be presented to permit the easy pouring of the sealing mixture.
In order to adapt the structure to different sizes of standard pipes, the opposite end of the section 7 is provided with the clamp 15 of which the screw 21 forms a portion. The cables 9 of the section 7 are rigidly secured to these clamps and then these clamps may be brought into holding engagement with a portion of the cables 9 passing over any one oi the YlOlIll members 8 of the section 6 and tightened in such position by means of the screws 21 as is illustrated particularly in Fig. 3. From this figure, it will be apparent that only one struck out portion 10 is provided on each form member for each cable and that these various form members are overlapped slightly as is shown at 22. Because of this, the end member 14 of the section 7 may be inserted between the overlapping ends 22 of any of the form members 8 or the section 6, the cables 9 being permitted to pass through the space between these overlapping ends when the end members are flexed outwardly after the manner shown in connection with the member 11 in Fig. 3. Thus it will be apparent that the section "I may be secured to the section 6 at a poin between an" the overlapping ends of the form me Jers S by simply properly applying the on ns 15 in connection with the cables 9.
From the foregoing description, taken in connection with the accompanying sheet of drawings, it will be apparent that I have provided a form of structure capable of two adjustments, one being to adapt the form to various sizes of standard pipes and the other being to adapt the form to those slight variations in circumference found in pipes oi? the same standard size. From this it will be apparent that a great saving in initial outlay is rendered possible.
What I claim is:
1. In an apparatus for forming pipe joints, a plurality of sections each in themselves tormed of a plurality of separable members flexibly joined together, and means for detachably uniting said sections at various points. to form an annular form.
2. In an apparatus for forming pipe joints, a plur lity of sections each in themves formed of a plurality of separable members flexibly joined together, and means for detachably uniting one end of one section between any of the members of another section.
3. In an apparatus ,for forming pipe joints, a plurality of sections each in themselves i'ormed oi a plurality of separable members flexibly joined together, means for detachably uniting one end of one section between members of another section to approximately present the desired size, means jior joining the ends of the previously connected sections together about the meeting ends of a pair. of pipes, and additional means whereby the assembled members may be given a final adjustment as to size to properly fit said pipes.
at. In an apparatus for forming pipe joints, a plurality of sections each in themselves formed or a plurality of separable members flexibly joined together by means or flexible cable, clamp structure carried by one end of at least one section for detachable connection with the cable on the adjoining section, and means for tightening said sections in position about the meeting ends of: a pair of pipes.
In testimony whereof I afiix my si nature.
