Speccation of Letters Patent.

Patented Oct. 2, 1906.-

Application led March 17,1906. Serial No. 306,576.

To a/Z whom t may concern,.-

Beit known that I, CLnTUs G. HAEGERT, a Citizen of the United States, and a resident of Hawley, in the county of Grant and Territory of` Oklahoma, have invented a new and Improved Grain-Feed, of whichthe following is a full, clear, and exact description.

The purpose of the invention is to provide a machine which will take grain either headed or bound from a stack and feed it into a threshing-machine.

A further purpose of the invention is to provide a light and strong portable machine of economic and simple construction which can be drawn between two stacks to operate simultaneously on both and to provide means for independently adjusting the rakes at the sides of the machine to accommodate them to the height of the stack they are operating upon.

Another purpose of the invention is to provide a conveyer to receive the grain and means for automatically imparting to a rake an alternate forward and rearward movement and an alternate gathering and discharging movement.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

' Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the machine, showing portions of the vertical shafts at each side of the machine and showing also the horizontal shafts in full at each side of the machine. Fig. 2 is a front elevation of the machine, illustrating the manner in whichI it operates. Fig. 3 is a plan view of the machine, and Fig. 4 is a detail perspective view of a portion of a rake-carrier and a rake attached thereto.

The frame of the machine consists of two side pieces 10, suitably braced, from which side pieces hangers 11 extend downward, and axles 12 are journaled in the said hangers and provided with suitable supportingwheels 13. A drive-shaft 14 is journaled in the forward end portion of the frame, extending through both ofl its sides, and said drive-shaft is provided at one end with a driving-pulley 15 and adjacent to said pulley is also provided with a gear 16, while a similar gear 17 is located at the opposite end of the shaft outside of the frame.

An endless conveyor-belt A is mountedwto travel the full lengthv of the side pieces of the frame and likewise along an upwardly-inclined extension A from the side pieces lat yat this pointl by suitable guide pulleys or wheels 19, and the said belt is likewise passed over a drum or its equivalent at the upper end portion of the extension A from the main frame.

A vertical screw-shaft is located at each corner of the machine, thescrew-shafts upon one side of the machine being designated as B and the screw-shafts at the opposite side of the machine being designated as B, and both sets of screw-shafts are illustrated in Fig. 1. These screw-shafts B and B are j ournaled at their lower ends in bearings 20, extending outward from the frame, and at the forward end of the frame the screwshafts at that end of the machine are journaled at their upper extremities in diagonal cap-blocks 21, (shown best in Figs. 1 and 3,) while the upper extremities of the screwshafts at therear end of the machine are journaled in ordinary blocks 22. Brace-rods 23 connect the cap-blocks 21 and 22 at the side portions of the machine, and corresponding rods 24 connect the blocks at the end portions of the machine, and a further central brace 25 is usuallyemployed, extending from one end brace 24 to the other, as is shown in Fig. 3.

A bevel-gear 26 is secured to each screwshaft B and B at its lower end, and these bevel-gears 26 mesh with gears 27 on the end portions of adjusting-shafts 28, one of which shafts 28 islocated at each side portion of the frame, and said shafts arer independent of each other and are journaled in suitable bearings 28a, and at the forward end of the said adjusting-shafts 28 crank-handles 29 or their equivalents are secured, so that the screw-shafts can be manually revolved whenever desired. It is obvious that each side set of shafts B and B is independently operated.

- shown in Fig. 2, and each of the driven shafts C and Cis provided with a longitudinal slot or groove 30, extending the lengththereof, andwith a bevel-gear 32 at the lower end. The bevel-gear 32 on the shaft C meshes with the bevel-gear 16 on the drive-shaft 14, and the bevel-gear 32 of the driven shaft C meshes with the gear17 on the said driveshaft, as is shown in Fig. 2.

Each of the screw-shafts B and B is provided with a bearing held to travel thereon,

the saidbearings being provided each with a longitudinally-threaded bore, so that by the rotation of the said screw-shafts the bearings will be made to travel up or down said shafts, according to the direction in which the shafts are turned. The bearings on the shafts B are designated as D and those on the shafts B as D. The bearings for each set of shafts carry the same mechanism.

IA horizontal screw-shaft E is mounted to turn in the front and the rear bearings D, and a corresponding shaft F/ is mounted to turn in the "corresponding bearings D. The shaft E at the front is rovided with a bevel-wheel 33 and the shaft with a corresponding wheel 33a. The wheel 33 engages at its upper edge with a bevel-pinion 34 and at its lower edge withv a bevel-pinion 35, both of which pinions are free to turn on the driven shaft C, the lower pinion being held in proper position Vrelative to the wheel 33 by an arm 36, eX- tending from the forward bearing D, through which arm the shaft C loosely passes. With reference'to the'wheel 33a on the other side of the machine and carried by the screw-shaft E it engages at the top with a bevel-pinion 34a, corresponding to the bevel-pinion 34, and at its lower portion engages with a bevelpinion 35a, supported by an arm 36a from the front bearing D, it being understood that the pinions 34a and 35u are mounted to slide on the driven shaft C. The opposing faces of the pinions mentioned as on the shafts C and C are clutch-faces, and a double-faced clutch Z is mounted toslide on the driven shaft C between the pinions 34 and 35, being adaptedv for engagement with either. A corresponding clutch d is similarly mounted on the driven shaft C, adapted for engagement with either pinion 34EL or 35a, and the clutches d and d are provided with feathers which enter the grooves 30 in their respective shafts. Thus it will be observed that by the up-anddown movement of the clutches d and d the screw-shafts E and E are turned in one or the other direction and that the screw-shafts at each side of the machine are independently o erated;

An e bow-lever 37 is mounted upon the forward bearing D, which lever is weighted at the upper portion of its vertical member and its horizontal member is pivotally connected with the clutch d. A similar lever 37a is mounted upon the forward bearing D engaging with the clutch d to operate the same. The clutch d is operated bythe shifting of a bar 38, which is located above the screw-shaft-E, as is shown in Fig. 1, and one end of the shifting-bar is attached to the vertical member of the elbow-lever 37, while the other end is provided with a slot 39, through which a pin is assed into therear bearing D, and this shifting-bar 38 is provided at its forward end with a horizontal inwardly-extending pin 40 and at its rear end with a corresponding pin 41. The elbow-lever 37*l at the opposite side of the machine is connected with a similar bar 38a, having a slot 39et at its rear end, through which a pin is passed into the rear bearing D. This shifti ng-bar 38, whichis above the screw-shaft E is provided at its forward end with a horizontal inwardly-extending pin 40a and at its rear end with a corresponding pin 41a.

A horizontal plain shaft, which may be termed an "agitating-shaft, is journaled at its ends in the lower portions of the bearings D of the screw-shafts B, and said agitatingshaft, which is designated as F, is rectangular or polygonal in cross-section between its ends and is provided at its forward end with a bevel-pinion 42, which meshes with a similar pinion 43, mounted to turn on the driven shaft C and to have vertical movement thereon, having a feather which enters the groove 30 of said shaft, and the. pinion 43 is supported in position by a lower arm 44, projected from the said forward bearing D, through which arm the shaft C loosely passes. With reference to the other side of the machine, its construction is duplicated, the agitating-shaft being designated as F the pin- IOO IIO

ion of the shaft as 42a, the pinion on the main thereon near each end. The cylinders 45 are eccentrically mounted on the agitating-shafts F and F. Each rake-carrier is provided with a hanger G, having connected vertical arms 47, the lower ends of which are fitted to freely slide on the shafts F or F, the said shafts having no influence on the said hangers. The endinember 47 of eachhangeris provided with an interiorly-threaded attached sleeve 48 at its upper end, and the sleeves of the hangers at one side of the machine may be mounted on the screw-shaft E, and the sleeves of the hangers at the opposite side of the machine are mounted on the screw-shaft E', as shown best in Fig. 1. The rear sleeve on the rearmost hanger on each sleeve is provided with an upwardly-extending pin, the pin on the sleeves traveling on the shaft E being designated as 49 and the sleeves traveling on the screw-shaft E as 49, The forward sleeve of the forward hanger traveling in the screw-shaft E is provided with a pin 50, and the sleeve of the corresponding hanger traveling on the corresponding screw-shaft E is provided with an upwardly-extending pin 50a. When the hangers are made to travel in direction of either end of the machine by reason of the rotation of the shafts E,when

said hangers reach the rear end of the machine the pins 49 and 49il strike the pins 41 and 41, respectively, and cause the shifting-bars and E', causing the hangers to again travel rearward, and so on. This alternate forward and rearward movement of the rakecarriers is produced while the machine is in operation. When the shifting-bars 38 and 3S21 are moved forward, the clutches d and d are brought into engagement with the lower pinions 35 and 35l and turn the same.

The rake-carriers at both sides of the machine may move simultaneously in the same direction, or, as shown, the rake-carriers at one side of the machine may move forward while the rake-carriers at the opposite side of the machine move rearward. rlhe rakes at each side of the machine are connected in any suitable or approved manner-as, for eX- yample, by a longitudinal brace-rod 53 and cross brace-rods 54, as is shown in Fig. 1.

A carrier G is provided for each rake, and each rake consists of a head 51 and any desired number of teeth extending outward from the head in parallelism for any desired distance. The rake-heads 51 have a hinged connection 51a with the straps 46 on the eccentric carriers, as is illustrated best in Fig. 4. The rake-teeth 52 are provided with sharp spurs 55 upon their under faces, and the said spurs are given an inclination in direction of the rake-head, as is shown in Fig. 2. For

convenience in storing the machine when not in use the rake-arms 52, carrying the spurs 55, which arer necessarily long, are usually made in sections connected by hinges 56, so that one section can be folded over upon the other and the two sections drop down-at the sides of the machine.

It will be observed that by reason of the rakes being attached to eccentrics which are revolved the said eccentrics as the shafts F and F/ are turned, give a raking or a reciprocating motion to the rakes, causing the spurs to travel back over the top of the stack, with which they engage, as is shown in Fig. 2, and then again inward or in direction of the machine, thus compelling the hay or grain which they rake in to drop upon the conveyer A, by means of which it is carried to the feed-table of the thresher.

Inclined platforms 57 are located at the lower side portions of the machine, which platforms extend down to the ground and facilitate the gathering of hay on the rakes,

' particularly when the crop to be gathered is scanty.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
