Be it known that l, WLLLIAM G. limo/n- HOFF, citizen oi the United States, 1" siding at Chicago, in the county of (,oolcand Stntc of Illinois, have invontcd a certain. new and useful lln novcmont in. iidjustablo Brackets, of which the following is it full, clean, concise, and exact description, rclorenco being had to the accompanying drawings, forming a port of this specification. 7
My invention. rclntos to brackets, particulady to brackets used in vohicles, such as stcnnnrnilw21y or electric curs, tho purpose of thc brackets lining to oll'or hearings, or run ways, for rogistcr or ball rods or cords. In: the present stage oi the art, brackets for this purposo arc usually cast integral, but as those vohiclcs (iii 'in shops, and tho particnpplicntion of the brackets di'llors, those-mist brackets :ind thnir manufacture are very expensive. Special attorns must be made for each form of bmc rot, and practically for the least vnriotion in, the form. l ndcr thosc circumstances, it is nlso nnprolliziblo to mmiuhicturo bra-charts oi a certain kind in largo numbers to hoop them in stock, thoro may not be anothc'c call For n 'pnrtionlnr l'orm lot a long time.
ho lllitlll olricct of my ii'ivontion, thoroi'orc, is to provide on ndjnstoblo bmchot in which all tho principal and expensive parts may be tho some for any size or form oi brockc t,
The parts oi the bracket usually comprise a, hood, which oil'cis n homing for n rcggistcr rod or cord, and o, homing or oyo for the bell cord, usually. l.his hood part is carried by arl'ns "which tormiinito in loot lnolnbcrs, by moans ol which tho hrnckot may be secured tothc support. 'lho l nd mombcr and tho loot int-inborn iorm tho most complicated port of tho lnnclwt, and must thorol'oro boot" n particular l'orm, whore-as tho arms may bc of any form or construction. in. prior dcvices of this kind, as bolol'c stated, the bond and foot ports and the arms :1 in oust in tcgrul, but in nccordunco with my invention, tho hood and foot momhors arc sopurnted and only be mill-1c for all brackets, whilo tho arms are. sonar-able, and which may be out from stock lllatimlztlfll any lcngih. hozid part i. practically n in txxo urls, which are nivotvd touothor, and the Foot 'IlKIHlNIS are also pivoted, the whole (ombinotion producing; lHTfLCliOl; whiwh (am ho changed into various forms to fit almost any vehicle or any corner 01' supports in the vehicle. The head and foot parts can there fore; be formed in great nun'ibcrs, and con.- soquently with much less expense, and can be kept in stock. W hen an order is received,
it is only nccossary to make a suitable number of the single arm members, which, when connected with the head and foot parts, will moot the specifications.
My invention i best understood and described by reference to the accompanying drawing, in which Figure 1 is o side elevation of a complete bracket; Fig. 2 is an end elevation from the loft, the top being shown in full, and the lower port being shown in section alon the line 2 --2, and Fig, 3 is it view of the hen 9nd showing a modified arrangement.
Tho hcnd port is composed of two similar members, or halves, 1 and 2, each having a body port 3 in the form of an annular sleeve, from which vxtonds :1. threaded lug 4, and from one or from both of which may extend a lug or eyelet 5, having the opening 6. These halves arc pivoted on a steel tube 7, this tube being originally straight and after application being riveted at its ends 8 and 9 to clmnp the halves togethcri'nto frictional, pivotal. engagement. The halves 1 and 2 at thcir outor edges have the recesses 10 and 1.].
*spcrtivoly, into which the riveted ends 8 and 9 dispose themselves when the tube is iivotcd over, in order that these ends are iiush with tho edges of the halves. The throndod lugs are preferably oil'set so as to lio in tho same plane when tho halves are brought iogethorl The threaded lugs rc- (oivc the arms 12 and 13, and these arms may be cut to any length from stock material of any form. The other ends of the rods arc also ihremlod-and are engaged by ihrondod lugs Ill and 15, which may bv of any shnpc and to which are pivoted TQSPQU" lively tho foot nwmhcrs 16 and 17. These foot members oomorisc the base part 18 and tho two extensions 19 and 20, which reooive the 0nd of the respective lug 14 or 15 to be pivoted thereto as by means of a pin, 2.2!.
, ifihich rod has rightand left threads restocrv lively Ell its ends, and provision is madn so that the rods may bo turned by means of a tool. if the rods arc polygonal, they can easily be turnod by wrench, for instance, and whom thoso rods are round, the grooves 22 and 23 are cut opposite to each other in the rod surface to form an application point for the tool.
With this construction, it can readily be seen that the parts can be so disposed with relation to each other as to produce a form of bracket which will meet almost any conditions and which Will lit in almost any corner, or against any support. The head parts, and the foot parts comprising the foot members and threaded lugs, are standard, and can be manufactured to advantage in great numbers and kept in stock. Whereas heretofore it required a long time to till an orderby reason of the necessity for special patterns and the manufacture of all the parts, by means of my 'lIlVOIllLlOIL a large -order can be turned out in very short time, as the only work necessary is the manufacture of the rods, and to those skilled in the art it is plain that the work and time required to linish a great number of such rods is very little. Another point is, arms formed of rolled metal possess a much greater strength to the square inch of section. than cast arms, the result being that the brackets can be made very much lighter. The lugs 5 may extend at any angle from the halves, .ie eye lug shown in Fig. 1 being opposite one ol the threaded lugs 4, while in Fig. 3 the eye lug is at forty-tive degrees thereto. When thus placed at an angle, greater variation of form can be given the bracket. The fact that the foot members 16 and 17 are pivoted to the lugs 14 and '15 respectively, and said lugs are threaded to the respective rods, the effect of a universal coupling is produced and the feet may assume any angle with respect to the rods,- to thus adapt themselves to any form of support. The tube 7, besides acting a rivet tor clamping together the/halves of the head part, forms a bearing bushing for the actuating rod which connects with the register. The halves and the bushing may be made smaller where a register strap or cord is used instead of a rod.
The various parts forming the bracket may, of course, be made of many different shapes, sizes or relative proportion, without departing from the scope of the invention.
I desire to secure the following claims by Letters latent:
l. in a device of the class described, the combination ol' a head part, toot members, and adjustable arms connecting said head with the foot members.
2. In. a bracket, the combination ol a head part, supporting arms having adjustable connection with the head part, and loot'memb\ v having adjustable connection with the arms.
3. in a bracket, the combination ol a head part, arms having separable and adjustable bers having separable and adjustable connection with the arms, and means l'orsecnring the head. part and toot parts to the arms 'atter assembly thereol.
4. In a device of the class described, the combination of a head part having openings therethrongh for receiving arod or cord, lugs extendinglrom the head part, arms lliLVring separable engagement in said lugs, loot members having separable engagement with the other ends of the rods, and means lor securing together the head niembers, loot members and rods after assembly thereof.
5. In a device of the class described, the combination of head members and foot 30 members adapted to be connected together by separable arms of different lengths whereby the brackethecomes adjustable.
