Application led July 7, 1905. Serial No. 268,645. y.

To all w/Lo//t Iit /m/j/ concern lic it known that I, WALLACE F. MAG- (lano'on, a citizen of the United States, and a resident of Racine, county of Racine, and State olf` Wisconsin, have invented certain new and useful Improvements in Threshing-Machines, oi' winch the following is decla-red to be a full, clear, and exact description.

The invention relates to the frame or casing of thc threshing machine and seeks to provide a frame formed of structural metal bars which will be comparatively light in weight, but which is so arranged that great rigidity and strength is given to the structure and in which provision is made for properly supporting the different operating parts of the machine.

The invention consists of the features of construction, combinations and arrangements of parts hereinafter set forth, illus- Atratcd in the aeconipanyingdrawings and more particularly pointed out in the appended claims.

In the drawings Figure 1 is a side view ot' the improved frame or casing. Fig. 2 is a lorwitlidinal section thereof. Fi f. 2 is a detail front view. Fig. 3 is a cross section on line 3 3 of Fig. 1 omitting the straw carrier andgrain pan.v Fig. 3 is a detail perspective view of one of the filler blocks. Figs. 4? und 5 are, partial sections of the side wall and deck respectively taken on line 5-5of Fig. 1. Fig. G a detail scc tion on lille (--ti of Fig. 3. Fig. is an enlarged detail view illustrating the manner in which rtain of the operating shafts are supported from thermain and sub-sills. Fig. S is a detail perspective view of' one end of the shaft supporting brace bar. Fig. 9 is an enlarged detail; view illustrating the connection between therearend f the main sill and sub-sill. Fig. 1 0 is a detail view showing vthe construction ofthe rear axle.

gln prior constructions employing a wood4 frame, the sills of the machine have been formed Ain separate sections. 'lhe rear scctions of the sills we re disposed -)ust above ,the rear axle and extended forwardly therefrom beneath the rrainLcleaniinr devices td a i' point about mid-way between the ends ot the machine. The forward ends of these sill .sections were connected by a reach to the tions and extended 'rearwardly from the front bolster to a point over the front ends of the rear sill sections. The overlapping ends of the front and rear sill sections were connected by suitable struts.

In the present improved frame the main sills 10 which are preferably formed of steel elnuuu-l-bars, are continuous and extend from front to rear of the machine. These main sills are elevated above the irout and rear axles and above the grain-cleaning devices. 'l`he uprights of the frame formed of suitable structural steel bars, are rigidly secured lo the sills 10 and the two rear pairs of uprights 11 and l2 depend below the same as shown. Beneath the rear ends of the main sills 10 are arranged the short subsills 13 which are rigidly secured to the lower ends of the rear uprights 11 and 12. 'lhe rear'axle is secured to the sub-sills 13. inclined strengthening brace-bars 14 are connected to the front ends of the subsills 13 and at their lower, rear ends, and their front, upper ends are connected to the main sills l() nea r the forward ends thereof, but in rear ot the connections between the main sills and the front axle. Connecting bars 15 dcpeud ironl the forward ends of the niuin sills 10 to the bolster of the front axle. In the construction described, the weight of the machine and the thrust as the machine is drawn forward or back, is largely taken on the continuous main sills. This construction obviates the necessity of employing any strengthening reach between the front and rear axles, and the front wheels may therefore be turned completely under the machine to turn sharp corners or for shipping.

The main sills 10 as stated` are preferably formed of channel bars, the tlanges of which are turned outwardly (see Fig. 3). 'the sub-sills 13 are also .formed of channel bars having outwardly turned flanges and are arranged directly beneath the main sills 10 (See Fit-l. 4:).-I4 'libe 'extreme rear and ex-fl treme forward uprights 11 and lt are preierably formed ol angle bars while the intermediate uprights 12, 17 and 18 are fortified ot' T-bars.m All the uprights hate their flanges turned outwardly as shown, andare bent over and secured to the outer faces of the nfain sills and the lower ends of the two rear u rights 11 and 12 are bent over and secure to the outer faces of the .sub-sills 13, To aford; i1 4'firm bearing/(for the' u'prights at their connections with the main and subn sills, ller blocks 19 (see Figs. 3, El ande) are arranged within the channel-bar sills .l0

and 13 .opposite the uprigl'its, and these blocks are provided with openings through which the connecting* bolts or rivets 2O ex tend. '.lhe uprights are all bent as shown, so that their flat, inner faces are in line or in the sanne plane with the inner faces o1' the sills. Longitudinally ezitending deck supporting bars or beam 21 are connected to the upper ends of the uprights and these beams are preferably/:termed of steel angle bars with outwardly facing llanges. The upper ends of the nprirghts are also pre erably bent outwardly, as shown in Figs. E3 and 1, to bring the inner faces of the bars 21 in line with the inner faces of the up@ rightsand silla 'Ey this arrangement the thin plate metal sheathing 22, which 'forms the walls oi the inclosine; casingof 'the 1nachine, may be conveniently bolted or riveted to the inner faces of sills 10 and 13 and to the inner faces of uprights 17 and longitudinally extending bars 21. That is to say, the plates do not have to be bent or shaped to'fit in place but, what is more important with this arrangement', the. interior walls of the casing are devoid. of any obstructions which would interfere with the proper passage of the straw through the machine. 'At the saine time by bendingw the uprights outwardly over the ,sills and the deck bars, rigid connections can be secured between these members of thefraine without in any way weakening themw The plate nietal'sheathing 23 (see Fig. 5), which forms the deelt of the machine or top of the inclosing casing),- therefor, rests upon and is bolted or riveted to the horizontal outwardly profi'ecting flanges 'of the decl; bars 21. lreiierably as shown in Fig. .3, these deck plates slope or are inclined dow wardly from the' center line of the machine at a slight angle to the horizontal and their edges extend beyond the bars 21 and lieti.'-

which project, upwardly and these decl; beanie are also preferably arranged in line with the uprights 12, 1T and 1S so that the weight of the decir 1s borne on the npr its rfc central, longitudinally extending 'iba-f 2Q extends along*y the under side of the di fl; ,f-'heathing 23 at its central portion, and is secured thereto and :to the transverse deck beams 25 by bolts or rivets.` Preferably also7 sa Looser? is ai'orde'd to the interior of the casing v'and to the beat-er and forward endet' the` straw rack. The central longitudinal deck bar 26 between the uprights 17 and 1S, and 16 'and 18, is provided with the strips 29 and 30 (see Fig.. 3) whichpare bolted or riveted 'to the upper face thereof. The edgesv o1 the lower strip 29 are bent downwardly to form spaces which receive the inner .edges of the slides 28. .lhe side edges of the slides 28 abut against the edges 'of the T1bar deck beams 25 (see Fig. 6), and are held in place and guided by strips 31 and 32"secured rto the illanges o the T-bars. This arrangement oli guide strips preventsany leaking at the edges of the slides. The outer edgesoi'the slides are provided with downturned lips 2l which correspond to the lips 24; oi the' stationary deck plates. These lips also form a convenient handle by which. the slides may be moved to and from position.

The sub-sills 13 are secured to the lower ends ot' the rear v'uprights 1l and 12, as described. Each is also connected to the lower end of a heavy lil-shaped brace bar 33, the legs of which diverge upwardly and are bolted to the lower lflange 'of the main sill` 10. lhe lower portion' of th brace is bolted to 'the 'upper lange of the sub-sill '13 just above the rear axle. The rear axle is formed oi two channel bars 311 with their flanges facing inwardly toward-each' other. The joiiirnal pieces Z upon which the wheels 36 are mounted, are secured in place between the channel bars Bel hybolts 87 which also secure the separate channel bars of the axle together. 'lhe axle issecured each end to the sub-sills by bent straps 38, which extend beneath the same and which are bolted to the lower flange of the sub-sill, and by a bolt 39, which extends through the straps B and journal pieces 35, and also through the llanges of the sub-sill and through the lance-bar The sub-sills are iurther braced by crosslatticebars40, which extend diagonally from cach end of the sills and by a cross angle-bar 4:1 extending between their rear ends.

olf the uprights 12 and are secured to the lower rear ends yof the inclined brace bars14. by bolts112. The lower ends of the brace hars are bent to horizontal position, as shown most clearly in Fie'. 7, so as to rest properly upon vthe upper flanges of the sub rlhe forward ends of the. .sub-sills 13 projecty in front of the lower ends sills. These brace' bars are preferably formed of heavy angle-bars with one of its flanges projecting upwardly and the otherl outwardly, as shown. At the upper, for ward end of each bar, the upwardly projecting flange is bent over into engagement with the outwardly projecting flange, as shown in Figs. 7 and 8, and the bolts 43 which connect the'end of the bracebar to the lower flange of the main sill 10 extend through this lapped portion so that the brace-bar is not weakened at its point of connection with the main Sill. The intern'lcdiate uprights t7 extend below the main sill l() to the i11- elined brace-bars 14, and are secured to the upwardly extending flanges thereof, as shown in Fig. 7.

'lhe forward uprights 1G extend below the inainsills 10 and are connected by a heavy cross angle-bar 44. The extreme front ends of the niain sills are connected by a channel-bar 45. ,lhe. connections between the main sills and front axlel are preferably in the l'orn'i of angle-bars 15 bent to U- shape, their upper divergent ends being secured to the angle-bar 44 and the cross channel-lan' 45. The lower ends of the connections lli incline toward cach other and are bolted to a bolster or head 46 which is provided with a ball-shaped lower end fitting within a socket 47 of cast metal. This socket is bolted between the channel-bars 48, which form the l'ront axle. Journal pieces secured between the elianuel-lnlrs 48 carry the front wheels 5t). The pole 5l is rigidly secured to the'axle.

l t will be noted that the center of the ball and socket is slightly in the rear of the center of the journals for the wheels so that the weight of the machine tends to balance the pole which is usually long and heavy. This particular arrangment forms the subjectanattei.' of another application and is not claimedl herein. But the arrangement of the connections for the front axle obvi ates the neeessityof any king bolt or bracing reach therefor. Moreover, the :i1-rangement of the continuous main sill obyiates the necessity of any reach for connecting the liront and rear axles. In this construction the thrust or draft upon the pole is transmitted through the forwardly and rearwardly inclined connecting pieces 15 to the frontend ot' the main sill 10, and the draft is transmitted by the main sill and by the inclined brace-laws 14 to the sub-sill 13 and tl'iegrear axle. By doing awaywith 'the reach the weight of the machine is considerably reduced and the front wheels may be turned under the machine. Indeed, with the torni shown, the front wheels may be turned throughfa complete half circle to bring the pole" beneath the machine and thereby considerably reducing the amount 01 car space required in shipping.

llpon the forward ends of the main sills l0 and in frontof the upright 16 of the inain casing, is arranged a supplemental casing 52, thesidcs of which are formed ol` heavy plates having upright and horizontal projecting ribs 53 and 54. 'lhese plates are secured to the ends ot' the sills by bolts extending through the lower horizontal rib 5l and the upper flange ol' the sill. l'he journal boxes 55 t'or the cylinder sha t't 5o are secured to the upper horizontal rib 5l ot the casings. This shalt carries the threshing cylinder 57. In rear ot the cylinder is a cross angle-bar 57 extending between the uprights lti. A. sheet. nietal battle 57 de` pends vlronl the deck and its lower edges folded about the bar 57. ln rear ot' the battle is arranged a beater 5S mounted upon a transverse horizontal shalt 5t). 'lhis shalt projectsl through the .sheathing or side wallsI of the machine casing and is journaled in boxes (it) which are secured to and supported upon the outwardly projecting horizontal flange of the short angle-bars (3l. 'lho ends ol.' these bars overlap the flanges of the uprights 16 und lb and are bolted thereto. In order that the beater may be easily rclnoved for repairs and the like, the sheathing opposite the beater is -provided with a circular opening which is closed by a circular plate (32 rcinovably bolted in place. llhe transverse bar (ll extends across the plat'e G2 and its ends are. however removably sccured to the uprights l() and 18. By removing the bolts which hold the plate (l2 and bar (il in place, the beater cylinder can be. readily taken from position for repairs or the like.

'lhe straw rack till and grain conveycr (ll, together with its sieve (35, extend longitudinally through the casingl and are h'uilg, in the usual manner, upon arins (lli which are carried upon the rock sha l'ts (37. ln the 'l'orln shown the arnns titl are connected to the sha l'ts interna-diate their ends and the straw rack (lil is pivoted to the upper ends ot' the arias while the conveycr and sieve are piv otally connected to the lower ends thereof. The ends ol the shafts ('17 are journalcd in boxes (i8 which al'e supported upon and connccted to the upper llangc ol the main .sills ttl. llate lnctal slides t.) are arranged in the sides ol' the casing opposite the boxes (SS so that access is atl'orded lo the interiorol the niachine at the points ol' support for the straw rack and conveycr. 'l`he arms titl ou the l'ront rock shalt t7 are provided in the usual lnanncr with the depelnling extensions 70, which are connected by pitmen 71 to the cranked shalt. 72, which is rotated in any suitable niauncr .to reciprocate the straw rack and convejaa'. 'lbe ends of thel drive, shaft 72 are jonrnaled in boxes`73 which are secured to the lower,horizontal tlauge of the shaft supperting brace-bars 14 near the i shaft-supportin ter deck-bar secured to said transverse deckbars and strips secured to said center and transverse bars overlapplng the edges of I said slides, substantially as described.
