SHAFT-HANGER.

SPECIFICATION forming part of Letters Patent No. 699,943, dated May 13, 1902.

Application filed March 23,:'1901-A Serial No. 52,526. (No model.)

'T0 all whom, tm/tty concern: 'I y Beit known that I, CHARLES A. BRINLEY,0E Y the city and county of Philadelphia and Stateof Pennsylvania,'have invented an Improve! ment in Shaft-Hangers, of which the follo'wf. ing is a specification. l My invention has reference to shafthang` ers; and it consists of certain improvements all of which are fully set forth in the follow-n lowing specification and yshown in the accom'- panying drawings,which form a part thereof. The object of my invention is to provide a suitable construction of drop-hangerfor shafting, which,while retainingthegeneral characteristicshape of v'suchhangers found by eX- perienceas best adapted for the purpose, shall Aembody special improvements whereby commercial sections of rolled ironor steel may be employed in its' construction. Theresult. 'of such construction is-to produce ahanger Aof composite formand of 'great rigidity cou`- ,pled with lightness,thelatter features being secured by properly shapingand bracing thfe light rolled-metal barsusedinv the construe-i tion.

My object is further toV soconstruct the hanger that the lower or box-supporting portion may be detachable and employedin com-1 hination with hanger-bases havingthe arms of various lengths to secure different drops, thereby simplifying the manufacture to suit yall possible demands, and to provide means whereby the lower parts carrying the box can be made up without reference tothe drop and any one ofthe lower parts canbe employed with any upper part -of several; such upper parts, thus simplifying the manufacture.

In carrying out my invention I form the base and depending arms of the yhanger ofrr lighter rolled iron or steel, preferably: of LL shape i in cross-section, and I so'shape and combine the several parts that the proper c onfiguration isfsecured'with a simple bracing, Ll which permits lightness to be had withoutimpairing the f great -`stability and ri gidity`v sonecessary to shaft-hangers in commercial use. The lower ends lof the depending arms or body :portion of the hanger-frame are united Vby suitable bracing, adapted also to carrythe In place of making the lower portion of the hanger-frame arms or members integral with the: upper or base portion it may be made separate and riveted, bolted, or otherwise secured to the upper portion, as will be more fully explained hereinafter. The lower p01'- 4tion of the hanger may have the lower crossbraces'riveted or otherwise secured to the upright members; but I prefer to have the lower transverse brace detachably secured in place, so 'that the shaft and journal-boxinay be put into place Within the hanger from below and the brace and support for the box then secured in place by preferably detachable means,such asboltsf My invention will be better understood by reference to the drawings, in `which-- Figure 1 is a fronte elevation of a shafthanger embodying fmy invention. Fig. 2 is an inverted plan view ofsame. Fig. 3 is a 'side elevation of same;I iFig. 14 is a front ele- 'vation of a modiicationof same, showing the rdetachable lower portionV carrying Yfthe journal-box; and Fig. 5 isl a Aplan view of the hanger shown in Fig. 4.

A represents four depending arms of angleiron, their upper ends being bent outward, as at A', and their lower ends bent vertically, as

atffD.' The middle portions of these arms A vare oblique and also, preferably, spreading at their upper ends to give greater base of support. To make a sharp bend between parts A andfA, one rib of the angle-iron is notched out and the edges butted and the joint strengthened by corner-braces B. The outer pairs by the cross-plates C, riveted to them, sai'dfplates having the necessary holes c for attaching the hanger to the ceiling-timbers. These plates C are preferably of angle-iron,

vends of the footpieces A are connected in transverselyarranged,and in addition to these `thefangleiron arms A may be connected in pairsin' the other direction atthetop by bars lVB of any suitable cross-section,which are properly riveted in place, as shownv In thismanner the parts A, C, andlB makea strong and extensive base of support, andv thereby. pre- Vent any tendency to rocking due to strains upon the shafting.

The lower ends D of the arms A are preferably vertical, and hence parallel. They are lconnected in pairs by the braces H H, the two pairs of arms thus formed being also connect- IOC ed by braces E F. These braces E F are arranged at different elevations, so as to leave a space between them sufficient for the journal-box J, through which the shaft G passes. The other braces H H are at a middle elevation or between the levels of the two braces E F. As will be seen from Fig. 2, the brace E is composed of two U-shaped pieces riveted together to form an H-shaped structure, the ends of the arms being bolted to the flanges of the parts D of the lower body portion. The brace E is detachably secured to the said parts D by bolts K, whereby it may be removed for inserting the line or" shafting and then secured in place to support it. The adjusting and supporting screw e passes through the bar formed in this brace. The upper brace F is made in exactly the same way and is provided with a similar screw f for holding the box.

`The sorewf presses down upon the cap of the box, and the screw e presses upward under the bodyof the box, so that theirjoint action holds the two parts of the journal-box together, as well as adjusts its position in the hanger. The side braces H H are made like I-shaped struc- 'tures formed ot' two pieces riveted together and with the flanges riveted to the flanges of parts D, as shown in Fig. 3. Screws h pass through these braces H and act as adjusting and steadying devices for each side of the journal-box G. The braces F and H may be riveted to the parts D, as shown, or permanently attached in any suitable manner. 'lhe braces H, E, and F thoroughly connect and brace the ends D of the arms A, so as to inipart great rigidity, and form excellent supports for the screws, which directlyT sustain the journal-box.

The foregoing description more specifically relates to Figs. l, 2, and 3, in which the parts A and D are in one integral structure. I will now refer to Figs. 4 and 5, which show a modified form of base and a sectional construction for the hanger-frame. In these figures the arms A are made flaring, as before, but are riveted direct to the flanges of an angle-iron base B2. In this case the angle-irons B2 B2 are curved, as shown, and riveted together at the middle atb and constitute an X structure, the free arms of which are riveted to the upper ends of the arms A. The cross-plates C are used also in this case as in the other and may be of flat metal or rolled shapes, as preferred.

The lower ends of the arms A are preferably made similar to those of Fig. l, but shorter and without bracing. The journal-box-supporting devices,preciselylike those described, (except that the parts D are independent of the arms A, as shown in Fig. 4,) are then placed in position, so that the arms A overlap the parts D', and are riveted or bolted together at d. In this manner the lower body portion or j ournal-box-supporting structures may be made up in quantities and the upper portions of the hanger made to snit the special requirements as to drop or construction of base.

The lower body portion when made separate is the same for a number of different upper body portions or bases, and if these parts are kept in stock hangers of any desired drop or shape of base may be made by mere assembling of the upper and lower body portions by uniting the upright members of the two parts. Of course in cases Where a large order is desired of a hanger of one drop the upright members may be made continuous orintegral, as in Fig. l.

A hanger oi' this construction is cheap to make, is lighter, and consequently cheaper to transport, and is stronger than cast iron hangers commonly employed.

Vhile I have shown my improved hanger as made largely from angle-iron, I do not confine myself to any special cross-section of rolled metal, and while I prefer the construction shown as being an excellent embodiment of my invention I do v,not confine myself to Ythe minor details, as these may be modified without departing from the spirit of the invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
