Description
This invention relates to a device for positioning pipe components, and in particular to a device for accurately position one component on another in preparation for welding.
In general, it is difficult to orient one pipe component accurately with respect to another component, e.g.
an elbow on a pipe section. Obviously, if the components are not accurately aligned or positioned prior to welding, the finished product will be faulty. In the case of an elbow and a pipe section, the normal procedure is to place the elbow on the pipe section, rest one arm of a try square on the open top end of the elbow and make at least two measurements at spaced apart locations along the length of such one arm, If the distance between the pipe section and the square is constant and equal to the expected distance,(the length of the arc defined by standard elbows is known), then the elbow is properly mounted on the pipe section. It will be appreciated that such a method is not without difficulties. The procedures is time consuming and not always accurate.
The object of the present invention is to avoid the above defined difficulties by providing a relatively simple device for quickly and easily positioning pipe components in preparation for permanent interconnection, e.g. welding of the components.
Accordingly, the present invention relates to a device for accurately positioning pipe components prior to interconnecting such components comprising base means for *
13220~2 positioning the device on a first component; post means on said base means; and bracket means on said post means for carrying a try square, whereby, when the base means is placed on the first pipe component, the square can be used to accurately position a second component with respect to said first component.
The invention will be described in greater detail with reference to the accompanying drawings, which illustrate a preferred embodiment of the invention, and wherein:
Figure 1 is a perspective view of a positioning device in accordance with the present invention;
Figure 2 is a side elevation view of the device of Fig. l;
Figure 3 is an end view of the device of Figs. 1 and 2; and Figures 4 to 6 are schematic side elevation views of the device of Figs. 1 to 3 in use.
With reference to Figs. 1 to 3, the basic elements of the device of the present invention include a base 1 and a post 2. The base 1 is defined by an inverted V-shaped or chevron-shaped plate 3 with a pair of rectangular plates 4 connected to the bottom thereof. A generally U-shaped bracket 5 is provided on one end of the base for supporting a level 6.
A turntable defined by a pair of circular plates 8 and 9, and a Teflon (a trademark for polytetrafluoroethylene) spacer 10 is fixedly mounted on the base 1. A pair of diametrically opposed stove bolts 12 extend upwardly through the bottom plate 8, the spacer 10 and arcuate slots 13 in the top plate 9. Washers and nuts 15 are provided on the top end of the bolts 12. Thus, the top plate 9 is free to rotate by a limited amount with respect to the bottom plate 8 and the base 1.
The post 2 is carried by the top plate 9. The post 2 is defined by a bifurcated bottom portion 17, which includes a pair of spaced apart, rectangular plates 18 welded to the top plate 9, and a arm 20 pivotally and slidably mounted in the bottom portion 17. The arm 20 is defined by an elongated rectangular strip of metal which is pivotally connected to a slide 21 (Fig. 2) which rides in longitudinally extending slots 23 in the plates 18. The arm 20 and the slide 21 are fixed in one position by a bolt 25 and a nut 26. In any vertical position, the arm 20 is free to rotate 90 in two directions around the axis of a bolt 27, which extends through the slide 21 and the convex bottom end of the arm 20. A wing nut 28 is provided on the bolt 27 for securing the arm 20 in one position. Markings 30 are provided on the upper end of one plate 18 and on the lower end of the arm 20 for aligning the latter with the bottom portion of the post in vertical or angular positions.
A bracket generally indicated at 32 is slidably mounted on the arm 20. The bracket 32 is defined by a conventional hinge, one arm 33 (Fig. 3) of which is covered by .. __ _ _ ~ . _. ~ _ ~ _ _ __ _ _ .: _ ___ . __ _.. _ _ _ .. _ _, _ . _ _, .. , _ .. .
a plastic strip 35, so that the bracket can slide on the arm 20. A narrow, elongated slide 36 extends inwardly from the arm 33 through the strip 35 and into a longitudinally extending slot 37 in the arm 20. A bolt 39 extendlng out of the opposite side of the slide 36 and a wing nut 40 are used to fix the position of the bracket 32 on the arm 20. Another bolt 42 extends outwardly from the other side of the hinge arm 33, chrough the outer hinge arm 43 and a wing nut 45 for changing the spacing between the hinge arms 33 and 43, i.e.
for opening and closing the bracket 32. Lines and indicia 46 (Figs. 1 and 2) are provided on each side of the slot 37 on both sides of the arm 20 for indicating distance between the bottom of the base 1 and the square 47 (Figs. 4 to 6) mounted in the bracket 32. Because the arm 20 is vertically movable in the bottom portion 17 of the post 2, the lines and numbers differ on each side of the slot 36 and on each side of the arm 20 for providing a distance measurement at various locations of the arm 20.
Referring to Fig. 4, when using the device to correctly mount an elbow 48 on one end of a horizontal length of pipe 50, the base 1 is placed on the pipe 50. The try square 47 is mounted in the bracket 32, and the arm 20 is rotated to a portion perpendicular to the bottom portion 17 of the post. With the shorter arm 52 of the square 47 in the bracket 32, the longer arm 53 of the square extends horizontally away from the device parallel to the pipe 50. If '' ,'. ' ' ' the arc defined by the elbow 48 is known, i.e. if the distance between the top of the pipe 50 and the top end 55 of the elbow is known (which is usually the case), the arm 20 can be moved vertically on the bottom portion 17 of the post 2 to ensure that the elbow is properly located on the pipe 50. As mentioned above, the normal procedure is to make at least two separate measurements at spaced apart points of the spacing between the pipe section 50 and a square, with the square resting on the elbow 48. The markings 46 on the arm 20 are intended for use with various diameter pipes, e.g. 2" to 6"
pipe.
As shown in Fig. 5, when mounting a flange 56 on the end of a section of pipe 58, the arm 20 is maintained in the vertical position. With the short arm 52 of the square 47 in the bracket 32 and the long arm 53 extending vertically downwardly, is relatively easy to ensure that the flange 50 is perpendicular to the pipe 58 before welding. If the flange fitting 60 is an angled element (Fig. 6), the arm 20 is rotated to a position parallel to the axis 61 of the outer end of the fitting 60. The longer arm 53 of the square 47 is mounted in the bracket 32 and when slid into engagement with the flange 64 provides an indication that the fitting 60 is properly positioned on the pipe 58.
It will be appreciated that because of the turntable defined by the plates 8 and 9, the post 2 can be rotated around its own axis for properly aligning elements which are , . , ~ .. .... . . .. . ... . .. .. .... ... . . . . . .

a plastic strip 35, so that the bracket can slide on the arm 20. A narrow, elongated slide 36 extends inwardly from the arm 33 through the strip 35 and into a longitudinally extending slot 37 in the arm 20. A bolt 39 extendlng out of the opposite side of the slide 36 and a wing nut 40 are used to fix the position of the bracket 32 on the arm 20.
