BEAM-CLAMP FOR PIPE-HANGERS.

V Specification of Letters Patent.

Application filed June 29, 1908.

Patented April 27, 1909.

Serial No. 440,848.

To all whom 'itrma'y concern:

Be it known that I, Join: II. DORAN, a citizen of the Unit-ed States, residing at Schenectady, county of Schenectady, and State of New York, have invented certain new and useful Improvements in Beam- Clamps for Pipe-Hangers, of which the following is a specification.

The invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. similar parts in the several figures therein.

Figure 1 of the drawings is a side elevation of the improved clamp and hanger secured to the lower web of an I-beam. Fig. 2 is an edge-view of the clamp and hanger detached from the I-beam. Fig. 3 is a top-plan view of the clamp mechanismdetached. Fig. 4 is a view in perspective showin a modified form of the clamping-members etached.

The clamping mechanism comprises a pair of jaws, 1 and 2, ada ted to engage with the lower web 3 of-an I- earn 4. The jaws are.

provided with supporting shanks, 6 and7, the shank 6 being provided at its longitudinal edges with the upturned angle-flanges 8, and the shank 7 with the similar flanges 9 so arran ed and proportioned that the shank 7 an its flanges will loosely. fit the space between the flan es 8, on shank 6, whereby the shanks are ree to slide longitudinally one upon the other to enable the jaws to fit webs of different widths. The shanks are provided with a slot, 10, along their longitudinal middle, so arranged as to register one with the other. The pipe-hanger comprises a yoke, 12, and hanger-arms, 13 and 14, which arms are apertured at their lower ends to receive a pipe-supportin bar or pin, 15. The hanger is secured tot e clamping mechanism by means of a screw-bolt, 20, passed up throu h the registerin slots 10 and inserted in t e screw-threade nut, 21. When the clam ing jaws have been adjusted upon the'web o the I-beam, they are secured in pllace by clamping the shanks tightly toget er, which is accomplished by the screwthreaded boltand nut. The screw-threaded bolt also asses through an a erture in the yoke of t e hanger and hol s the hanger tight to the shanks of the clamping jaws.

Similar characters refer to' The bar 15 may be made like an ordinary cotter-pin, as shown in Fig. 1, which can be easily inserted and withdrawn from the apertured hangerarms. One of the pin a )ertures is shown .at 23 in Fig. 1. It is o vious that different sized hangers may be used in connection with mechanism and adapted to approximately fit ipes of predetermined size. A pipe 24 is s own which fills the space between the hanger- arms 13 and 14.

The clamping jaws 1 and 2 and their shanks are referably formed from heavy sheet metal ystamping or pressing in suitable dies; and when desired, they can be made in modified form, as shown in Fig. 4-,.

in which form both the members are just alike, thereby requiring only one set of dies to form both members; whereas in the form shown in the other figures of the drawings where one shank is smaller than the other so as to fit therein, a separate die is required for each member. As shown in Fig. 4, the shanks have a single angle-flange, 30, along one edge, instead of an angle-flange along the two opposite edges. Consequently it is necessary to make the single-flange shanks heavier than those having an angle-flange on each of the opposite edges. Where the channel-formed shank is used, one shank fitting within the other, as shown, the clamping members can be made much lighter, as the channel-form affords great strength in proportion to the weight of metal employed.

It is obvious that a hanger of given size may be used to sup ort plpes of difiering sizes within certain imits, but hangersdiffering in size may'be employed for pipes differing largely in size. For example, a comparatively small sized hanger may be employed 'for the smaller sizes of pipe, and a arger hanger may be used for the larger sizes of pi es. The hangers being comparatively simp e and inexpensive, several different sizes may be provided, and the most suitable size used for any size of pipe. The use of the cotter-pin makes it possible to easily and quickly attach the hanger to a pipe. The han or being connected with the clam ing mec anism by the screwbolt 20, which passesthrough a middle aperture in the yoke of the clamp, the hanger can be. rotated to any an lar position relatively. to the I- beam w ich adapts the construction herein described to the support of pipes running in any angular direction relatively to the line of the clamping the beam supports; When desired, the slots 10 in the shanks 6 and 7 may be made in the form of a series of shorter slots, or bolt-holes, adapted to receive the screw-bolt 20, thereby'afiording greater strength to the shanks.

By havingthe'an le-shank of each member which contains t e longitudinal slot 00- cupy a horizontal plane instead of a vertical plane, as heretofore practiced, the bolt which clamps the two members together can be made to perform the additional function of sup orting the pipe-hanger, as shown, which ena les the operator to easily and quickly adjust the pipe-hanger in a osition to hold the pipe at any desired ang e, relatively, to the beam, and after the desired adjustment is once obtained, to securely clamp the hanger in such angular position by tightening up the screw-bolt, which securely clamps the two shanks of the beam-clamp and the yoke of the pipe-holder together, so that the parts will be securely held in place.

What I claim as new and desire to secure by Letters Patent is' 1. A beam-clamp for pipe-hangers, comprising two adjustable members, each consisting of an angle-iron shank rovided at one end with a clamping-jaw an having one I of its angle-flanges in a horizontal plane and containing .a longitudinal slot, the slots registering one with the other, and means for securing the two members together and to a pipe-hanger in differing positions, relatively, one to another.

2. A beam-clamp for pipe-hangers, comprising two adjustable members, each consisting of a'shank provided with oppositelydisposed angle-flanges, and at one end with a mid e-s ot, the shank of one member being narrower than the shank of the other member, whereby the narrower shank may be inserted within the wider shank and slide longitudinally of the same with the respective angle-flanges of one member in juxtaposition with the angle-flanges of the other member, and the two slots register with each other, and means for securin the two members in difiering positions re atively to each other.

In testimony whereof, I have hereunto set my hand this 16th day of June, 1908.
