To all whom it may concern:
Be it known that we, HENRY E. PRIDMORE and IVILLIAM R. BAKER, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Harvesters, (for which Letters Patent of the Kingdom of Great Britain, No. 7,693, were granted, with our knowledge and consent, on the Sth day of June, 1886,) of which the following is a specification.
An application' was filed iu the Patent Office ot' the United States on the 10th day of July, lS86,Se1-ial No. 207,666, by ourselves for Letters Patent for an improvement in harvester-frames In such application the sills and girts of the elevator-frame were described as formed of square pipe, or, in other Words, of tubes of rolled or forged metal, rectangularin cross-section; but the rear platform-sill was retained in the old and cumbrous wooden form. One feature of the present invention consists in constructing this latter sill, and also the divider-girt, of square pipe, and in accessory devices for uniting the divider-girt to the angle-iron linger-bar and tothe dividerboard, and also for protectingthe grain-wheel.
A further feature of the invention relates to the tightener for the platform-apron, and yet other features relate to the mounting of the inner roller of the platform-apron and to the supporting of the rear end of the seatplank over the elevator.
In the drawings, Figure l is a top plan vieuI of a machine embodying our invention, the platform-apron being ,removed to expose the tightener. Fig. 2 is a rear elevation of said machine; Fig. 3, an elevation from the diyider end; Figs. et and 5, enlarged .details in side and rear elevation, respectively, of the joint between the finger-bar and divider-girt;
Figs. G, 7 and 8, enlarged details in top planA the joint between the divider-girt and rearr sill of the platform-frame; Fig. 10, an enlarged detail of the platform in vertical transating parts of the apron-tightener; Figs. 17, Y
18, and 19, enlarged detailsin plan, cross-section, and side elevation of the bearing-box for the movable apron-roller; Fig. 20, an enlarged detail in side elevation of the grainwheel bra cket or rack-standard mounted upon the divider-girt; Fig. 2l, a horizontal section therethrough, showing also the grain-wheel on the correspondingly-numbered line in the preceding figure; Fig. 22, a vertical section, and Fig. 23 a horizontal section, as likewise indicated by numbered lines; and Fig. 24, a rear elevation thereof.
Now, proceeding to describe the invention, the front sillA of the platform-frame is or may be a bar of wood, as usual, forming a back to an angle-iron finger-bar A', which has its horizontal Web d uppermost and flush with the upper edge of said sill, and, being bolted thereto at intervals, strengthens and braces it. The front sill is overlaid by a wooden strip A2 to close the space beneath the upper ply or surface of the platform-apron when this is higher than the finger-bar. The rear sill B, as already intimated, is to-be constructed as a square pipe or tubular bar of rolled orforged iron, rectangular in cross-y section, occupying the Vplace of the customary Wooden rear platform-sill. At its outer or grain end this sill receives a metal bracket or spacing-block I3', having slings t) at its foot,whereby it saddles and closely embraces the upper side of the sill, and at its top a slightly-oblique seat b for the rear end of the divider-girt C, which likewise is a rectangular tubular barand is secured at this point by a bolt c, passing through the bracket and rear sill, thence entends forwardly pastthc finger-bai' and to the point of the divider, being suitably supported. adjacent to the finger-bar by an upright or standard therefrom.
To the inner side of the tubular rear sill, or
or board C2, placed on edge along said ,bot-
torn boards, which supports the rear guidebar c2 for the platform-apron, the front guidebar c3 being secured to the front sill in the usual way. The space between the plank and the rear sill vmay be covered by a lid C3, hinged to said plank, and thus form a toolbox, and this lid may at any time be turned up to act as a shield or wind-board for the rear of the apron.
Overlapping the rear sill of the platformframe at its stubble end and on its upper side is the rear sill D of the elevator-frame, also formed as a square pipe or hollow bar of rolled or forged iron rectangular in cross-section, and it may be here stated thatall of the sills or girts hereinafter mentioned are of similar form and structure, except that the girts will ordinarily be of less diameter than the sills.
When a wooden rear sill is used for the platform-frame, itis of such height as to come up against the rear elevator-sill and be bolted directly thereto, but the tubular sill will be ordinarily low down, and for a reason presently given it is often necessary to have the elevator-sill considerably higher. Therefore spacing brackets or lifts D of metal will beV employed between the two sills where they overlap. Two. of these brackets are employed, both having snugs CZ to embrace the platformsill and seats d for the reception of the ele.- vator-sill, onebeing located at the stubble end of the platform-silland the other at the inner or grain end of the elevator-sill, and bolts cl2 passing through the two sills and brackets complete the joint. The brackets are also offset at one side to form prolongations cl3 of the seats for the elevator-sill beneath the inner cross-girts of the elevatorframe, that said girts may be bolted through the sills to such oifsets, as presently explained.
As in the before-mentioned application, the front platform-sill and the finger-bar attached thereto are likewise overlapped by a tubular bar E of rolled or forged iron, also rcctangu,` lar in cross-section, which extends therefrom a suthcient distance to constitute the front sill of the elevator-frame. The rear elevatorsill is in line with the rear platformsill; b-ut the front elevator-sill usually iares somewhat from the platformsill, to which it is attached through the finger-bar, to give more space for the main wheel and binding attachment. Spacing-brackets are interposed between the front elevator-sill and iinger-bar where they overlap, in order to provide a space for the playof the sway-bar, Where such bar is located beneath the A-frame of the elevator, or to block up the elevator-base frame, which is also the gear-frame, to a higher level than the platform, and this in the present construction is the reason why such brackets are employed between the rear sills, as previously stated, although the sway-bar does not or need not pass between said rear sills, to wit, to bring the rear sill into its proper relation with the front sill.
F represents chairs such as employed in the Baker and Pridmore construction interposed between the elevator-sills and the crossgirts, of which latter four are shown, the innermost girt G in the angle at the foot of the elevator, then the two girts H H', constituting the lateral bars of the wheel-frame, and, nally, the outergrtl at the stubble end of the machine; but of course the number depends to some extent upon the type of machine or style of binder to be carried. The angle-iron nger-bar, the front elevator-sill, and the cross-girts are secured together in essentially the same way as heretofore; but as the wooden rear platform-sill is now dispensed with and spacing brackets or blocks employed between the two square 4bar rear sills the rear ends of the two inner girts are now secured by bolts passing through girt, chair, elevator-sill, and offset from the respective underlying spacing-block, while the sills themselves are united by bolts passing through each and through the intermediate block.
The front and rear guides for the platformapron are connected near the delivery end by a cross-beam K, upon which is fixed a metal bridle K', having guideways 7c for the play of a block K2 lengthwise of the platform. from this block a spindle 7a passes through the bridge connect-ing the two arms of the bridle, and a spring 7a2, coiled around the spindle and`resting at one end against the bridge and at the other against a collar or nut k3, secured to the end of the spindle, tends to constantly force or draw the block toward the divider. Brace-rods K3, rigidly secured to said block, fiare outward therefrom toward and are rigidly secured to the bearing-boxes ol for the gudgeons of the'idle-roller K4 of the platform-apron, and these bearings have flanges 706, sliding in ways formed in the divider ends of the apron-guides. Thus the idleroller is constantly forced ou tward toward the divider, keeping the apron taut.
The inner or non-adjustable roller L for the platform -apron has its rear gudgeon Z supported in a long sleeve-bearing l', that ex- IOO IIO
tends from the vertical plank C2 rearwardly means of an angle-iron bracket M, which sits upon the rear platform-sill at and rises vertically troni the foot of the inner strut, which is herein shown as forming a rear boardto the elevator after being suitably bolted to said strut and to the bracket-plate, which secures it to the rear sill, then extends horizontally a short distance toward the stubble side in order toform a seat to receive and support the seat-plank M', then passing at a slight upward incline toward said stubble side, is again bolted to the inner strut, and finally to the outer strut, making a very light and strong brace and siibserving two functions. y
As practically the whole platform-frame is of metal, it becomes necessary to modify the means whereby the divider and the grainwheel are supported. The divider-girt, it has already been explained, extends obliquely forward, and, as usual, is in a horizontal position. It has been noticed that it is blocked up from the rear sill by means of a spacingbracket. r1 his is not absolutely necessary, but is adopted in order to raise it above the level of the upper ply of the platform apron or carrier, thus allowing the end of the latter to extend beneath or be carried beneath by the action of the tightener upon its movable roller, so as to exclude the possibility of grain dropping between. It follows of course that the forward end of the girt will be correspondingly raised above the finger-bar, the provision for which will be directly stated. It is then continued beyond the finger-bar to practically the extreme point of the divideigwhere a shoe N, capping and covering its open end, is bolted toit, from which the inclined dividing-board N extends upwardly, outwardly, and rearwardly. A second or false shoe Nzis bolted to the divider-giri; somewhat to the rear of the divider-shoe, and is formed with a socket 7i, into which the point of the outer guard-fin ger n enters, partly to insure a clean division of the grain and partly to brace the finger-bar and divider-girt.
A metal upright O is bolted to the dividergirt immediately above the finger-bar and has an offset 0 sitting over said girt and secured by a cross-bolt to make the connection more certain, and beneath it is bent laterally and formed with a seat, which rests upon said finger-bar, and a flange o', depending along the vertical flange of said bar and embracingT it by a snug o2 at the bottom, and secured to said flange by horizontal bolts, while at its upper end it bends obliquely at oi", so as to be secured to and aid in supporting` the dividerboard.
The grain wheel P turns upon a stub-axle p, projecting from a sliding block p', sliding` in ways in a rack-standard P', and adjusted by means of a lever P2 and a dog controlled therefrom. Such rack-standard and the accompanying means of adjustment have been used heretofore upon machines introduced into the market by the McCormick Harvesting` Machine Company, with these' exceptions,
that the standard is now bolted to the tubular c injuries, a fender-bar R is bolted at r to the` grain end of the rear platform-sill, then is bent outward and carried forward outside of said sill until immediately in front of the wheel it reaches the just-mentioned upright, which connects the finger-bar, divider-girt, and grain-board, when it passes through lateral snugs r', formed integrally with the foot of said upright at and just above the grain end of the front sill and finger-bar, thence is bent obliquely inward untilI it reaches the front end of the divider-girt, to which it is secured, preferably, by the same bolt that unites the latter to the divider-shoe.
