SEAT-SPRING.

memes.

Application `filed.Eeleruary To all whom it may concern Be it known that I, VVILLmM C B-Inrriu, a citizen of the. United States, residing at'` Kalamazoo, Michigan7 have invented 1certain` new and useful 'Improvements in Seat- Springs, ofwhich the followingivsa *specifi-f4 cation.

seat springs. j y

My improved seat sprin'gis particularly similar seat boxes are employedl.

provide` an improved detachable seat spring for seat boxes which maybe quickly and"` easilyapplied or removedand one whichis` compact and. light in weight softhat it may be conveniently carried about and also one which is simple and economical in structure; Further 'objects7 andobjects relating Ito structural details," will definitely appear from the detailed deseriptionto follow.;

` I accomplish theobjects of my invention bythe devices and means described in the" following specification. The invention is clearly defined andy pointed out in the claims. c "A structure whichis a preferred embodiment of'myinvention `is clearly illustra'ted in the, accompanying drawing, forming a part ofthis specification, in which "Figure I is a detail vertical section of a structure embodying the features of my in]` vention. Fig.` II is a perspective view of theA springsupporting bracket with `the clarrip! in'g plate, springs and seat supporting'rod removed. F ig. Ulis a perspective viewfof" the bracket clamping plate. f ln the drawing similar reference `characters refer to similar parts throughout the` several views. j i

Referring to the drawing, the structure illustrated is an engineers or locomotive cab seat Lof' the seat box type in which 4a box 1 adapted as a tool or storage b'oX isp'r'ovided with a cover 2 hinged at 3 fand adapted as a seatE The cover is provided withl upholstery 4., These parts are shown in conventional form. Y f 7 .j provide a spring supporting bracket con-` sistingof a vertical armf5 adaptedto he` disposed against the inner side of the front wall 'pof the boX and an outer horizontal arm 6 resting upon the upperedge of the boX and projecting beyond "the same.-1 `The SpeccatonrofLett-ers Patent.

inner horizontal arm 7 of the bracket is provided with a vertical depending elongated :bearing S for the seat supporting bolt or rod 9; The clamping plate l0 is provided with atlange 1l at its'uppcr end adapted to rest on the top of the arm 6, the plate being r slotted at l2 to receive the arm. rlhe flange This lnventionrelates to::improvements` 1n lt is provided with an outwardly projecting portion `l?) having a threadedhole 14. therein n j for theset" screw 115. `This set screw is prodesigned by. me for. use` 1n any relation wheref1 vided with a winged head for convenience in adjusting. i The main obj ects of this invention are to 1 `The coiled springslt and 17 are arranged onewithinlthe other and their upper ends terminate in verticallyA disposed eyes 19 which'engage the bolt 20 :arranged through the vertical arm ofthe bracket so that the springs are supported toembrace the bearing S.'the bearing being spaced `from `the arm 5 to `accommodate the bolt 20.

The seat supporting rodl 9 is arranged through the horizontaleyes 2l at the lower l ends ofthe springs. Nuts 22 are arranged above and below the eyes 21 to secure the rod to the springs so that the rod is yieldingly supportedwithits upper end above `support the seat 2, as shown in the drawing. Y

lVith' the parts thus arranged the spring may be quickly Iand easily applied to the seat box, the clamp being adjustable so as to accommodate varying thicknesses of wall.

'Vith the parts thus arranged the stru@ .ture is compact and canbe readily carried aboutinthe pocket of the engineer so that he can take the same from one engine to another or remove it when leavinghis engine.-

The structure is economicalto produce and at the sametimeis very effective for the purpose. i

Having thus described my invention, what Iclaim asnew andjde'sire to secure by Letters'Patent,is:` 1`

l The combination with a boX provided with a cover hingedat 'one side, saidcover being adapted as a seat7 of a spring supportingbracket having a vertical arm disposed against the inner side of the box and an outer horizontal arm resting upon the upper edge thereof and projecting" beyond the same, and an "inner horizont-al arm provided with a vertical `elongated depending bearing spaced from- `said verticalfarm, an adjustableclamping plate having a flange at its upperT end `projecting at each side lli) CII
