GEORGE M. JONES, 'OF GREENSBURG, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO JOHN T. KELLY, OF BROOKLYN, NEW YORK.

PIPE-HANGER.

SPECIFICATION forming part of Letters Patent No. 422,945, dated March 11, 1890.

Application filed December 5, 1889. Serial No. 332,658 (No model.)

To all whom it may concern.-

Be it known that I, GEORGE M, J ONES, a resident of Greensburg, in the county of W'estmoreland and State of Pennsylvania, have invented a new and useful Improvement in Pipe-Hangers; and I do hereby declare the following to be a full, clear, and eX- act description thereof.

My invention relates to what are known as pipe-hangers that is, hangers employed for suspending lines of pipe or tubing from the ceilings or rafters in buildings-its object being to provide an efficient partible hanger which can be placed around the pipe after it is adjusted to place, and then connected to the supporting-bolt entering into the rafter or other part of the ceiling.

My invention comprises certain improvements in the class of pipe-hangers having two sections engaging with each other at the base and connected together by rings fitting past each other at'the top, a special feature of my invention being to construct the opening in the upper ring larger than the opening in the lower ring, to permit the swinging of the hanger and adjusting it to place to provide for slight movement thereof.

It also comprises certain other improvements, as will be hereinafter set forth, and claimed more particularly To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompany ing drawings, in which Figure 1 is a face View of the two parts of the hanger bolted together around the pipesection. Fig, 2 is a vertical central section showing the two parts of the hanger together fitting around the short length of pipe, Figs. 3 and 4 are perspective views illustrating the two partsof the hanger,

Like letters of reference indicate like parts in each.

My invention is illustrated in the most desired form thereof, though it is evident that its form may be changed without departing from the invention, as may be hereinafter briefly indicated, v,

The hanger is formed of the two sections a h, these two sections, when fitting together, forming what might be termed a ring divided vertically into two parts. These sections a b engage with each other at the base by any suitable joint 0, that shown being a slot in the section a, into which a tongue in the section b enters and seats itself, so looking the lower ends of the two sections firmly together when the hanger is closed.

At the upper end of the hanger a is the ring (Z, this ring extending out horizontally from the body of the hanger and passing over a like ring 6 on the section b, and the hanger in its simplest form being composed simply of the two sections engaging with each other at the base and having the horizontal rings cl 6 at the upper end fitting the one above the other, so that the bolt or suspension device f may pass through said rings and lock the two sections of the hanger together. I generally form the opening through the upper ring (1 of the hanger larger than that through the lower ring 6, so as to permit of the swinging of the hanger in adjusting it to place or provide for a slight movement thereof in case of the movement of the pipe from expansion or contraction or other cause. For the same reason I form the bottom face of the lower ring eon the section Z) slightly roundedfas at g, the lower ring having thus what might be termed a convex bottom face, thus providing for the swinging of the hanger on the nut h, which is screwed onto the bolt below the two rings of the l1anger,and so permitting the movement of the pipe without bringing great strain upon the hangen I find it desirable, in order to bring the two rings cl 6 into proper line, to provide shoulders on the sections, against which the rings will abut, by means of which they will be brought to proper line. In the hanger shown these shoulders are formed of the flanges 7c, and in the preferable form these flanges extend part way around each ring, so as to inclose the part of the ring of the opposite sec tion extending out beyond its end flanges, the two flanges thus inclosing the two rings and holding the upper part of the hanger in proper line, both as against longitudinal and transverse movement, and giving a neat finish to the collar, as the two rings are thus concealed within the flanges In the drawings I have shown the two parts the flanges, and, if necessary, the form of joint, or engaging device at the baseof the sec-i tions, the two rings can be brought into hue by a side movement, and this I include within myinvention,as the important feature thereof is the employment of the two rings through which the bolt or suspension device will pass The form, of suspension device employed is shown in Fig. 2, it being a bolt or barf, having the or-' when they are brought into line.

dinary woodscrew at the upper end and threaded at the base for the reception of the nut h.

When my invention is employed for sus-I pending pipe, the "bolts are screwed into the; beams or other wood-work in proper position;

' to receive the hangers, The two sections Gift the hanger are then taken and placed under l thepipe, their lower ends caused to engage;

by the joint 0 and the rings (1 e at the upper} endsof said sections brought into line with;-

each other, so closing the hangeryand the;

hanger is lowered around the pipe sothat itsj;

It is evident,

out any difficulty, and when united they form an exceedingly strong hanger, as strong as any cast in a single piece.

It is evident that the hanger maybe formed of any suitable material, either cast-iron, malleable iron, or brass, as may be found desirable.

WVhat I claim as my invention, and desire to secure by Letters Patent,is

1. A pipe-hanger formed of two sections engaging with each other at the base and each provided With a ring at the top fitting the one above the other, the opening in the upper ringbeing larger than the opening in the lower ring, substantially as and for the purposes set forth;

2. A pipe-hanger formed of two'sections engaging with each other at the base and each provided with a ring at the top fitting the oneabove the other,the lower ringhaving a convex orrounded bottom -f-ace,substantially as andfor the purposes setforth. 3. A pipe-hanger formed of two sections engaging with each other at the base and eachprovided with a ringat the top fitting the one past the other, and eachhaving a flange extending part wayaround the ring and acting to inclose the projecting portion of the ring of the-other section,- substantially as and for the purposes set forth.

In testimony whereof I, the-saidGEORGE M. J ONES, have hereunto setmy hand.
