RAKE.

SPECIFICATION forming part of Letters Patent No. 706,397, dated August 5, 1902.

Application filed March 4, 1902. Serial No. 96,588.' (No model.)

T0 all whom, it may concern:

Beit known that l, ANAH S. ELLIOTT, a citizen of the United States, residing at Mechanicsville, in the county of Cedar and State of Iowa, have invented certain new and useful Improvements in Rakes, of which the following is a full, clear, and exact description.

My invention relates to improvements in rakes especially adapted for use in gathering cut stalks which lay in windrows into shocks preparatory to burning or otherwise disposing of the stalks, althoughthe rake may be used for other purposes. Y

One object of the invention is to provide an improved construction of the rake-head in which the teeth are clamped against any possible endwise or lateral displacement, and at the same time the clamping devices serve to bridge the space between the 'longitudinal bars of the rake-head in order to strengthen the latter'.

A further object of the invention is to provide a simple and durable construction of the machine inwhich the parts Aare arranged to allow easy turning of the machine at the end of the field, and provision is also made for readily discharging the load accumulated by the operation of the rake.

With these ends in View the invention consists in the combination, construction, and arrangement of parts, which will be hereinafter described, and the actual scope of the invention will be defined bythe claims.

Reference islto be had to the accompanying drawings, forming part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure 1 is a plan view of a rake constructed in accordance with my invention. Fig. 2 is a vertical section on the line 2 2 of Fig. 1 looking in the direction of the arrows. 3 is another vertical section on an enlarged scale, the plane of the section being indicated by the dotted line 3 3 of Fig. 1, also looking in the direction of the arrows. enlarged vertical vcross-section through the rake-head, illustrating one of the clamps for a rake-tooth, said clamp serving as a bridge for the longitudinal bars of the rake-head.

Fig. 4 is an of said Fig. 4. Fig. Gis a detail perspective view of one member of a clamp adapted to secure a tooth in the rake-head. Fig. 7 is an elevation Aof a modified construction of the 5 designates the axle of themachine, and G represents the carryingwheels, which are properly mounted on suitable spindles at the The draft-tongue 7 is provided at its rear end with the cross-bar 8,Which is nearly equal in length to the axle, and this cross-bar of the tongue is loosely connected to the axle by means of the interlocking eyes 9, said eyes being fastened to the axle and to the tongue-bar 8, as clearly shown by Figs. 1, 2, and 3. A doubletree 10 is connected to the tongue near its rear portion, and the seatspring 11 is also fastened to the rear extremity of the tongue, said spring serving to carry the drivers seat 12 and being braced in proper position by means of the stay 13.

A supporting-frame for the rake-head is provided on the wheeled axle, said frame extending rearwardly from the axle and adapted to support the means for adjusting and locking the rake-head. This frame consists of the parallel bars 14 14a, the cross-bar 15, and

f the brace-bars 16, all of these parts being firmly secured together by any approved means. The parallel bars 14 are fastened to the axle, and they are extended a suitable distance beyond the cross-bar 15. The bracebars 16 are fastened to the axle and to the cross-bar 1 5,and these brace-bars are equipped with suitable'bearings 17, which accommodate the trip-shaft 18. Said trip-shaft is disposed across the carrying-frame in rear of the seat, and said shaft is provided at :its end On the crossbar 15 yof the frame are provided suitable 'keepers 20, which receive the slidable latch- `bolts 21, the latter being provided at their front ends with the slotted heads 22, adapted to receive the crank-arms 19 ofthe trip-shaft 18. The trip-shaft is held normally in an active position by means of a coiled spring 23, which is attached to a portion of the tripshaft and to the cross-bar 15, and to said tripshaft is operatively connected a link 24, the front end of which is attached'to a crank 25 on a treadle-lever 26, the latter being pivotlOO ally mounted, as at 27, von the axle and having a foot-piece 28, which is disposed within convenient reach of the drivers foot, all as shown more clearly by Fig. 3.

The side bars 14 14a of the supporting-frame are provided at their extreme rear ends with suitable open bearings 29, which are disposed in transverse aliuement and serve to loosely support the rake-head, so as to permit the latter to turn on its axis. The rake-head is disposed in rear of the axle 5, parallel to the latter, and this rake-head is much longer than the axle in order that the end portions of the rake-head may extend for considerable distances beyond the opposite sides of the carrying-wheels 6, as shown more clearly by` Fig. 1. The rake-head consists of longitudinal bars 31, a plurality of double-ended teeth 32, and a plurality of clamps` which are individually engaged with the teeth and have interlocking engagement with the parallel bars 30 3l, so as to rmly hold the said teeth 32 against endwise or lateral displacement within said parallel bars, each clamp serving to bridge the space between the bars and the series of clamps affording spaced bridges to thoroughly brace the bars forming the rakehead.- The parallel bars 3Q 31 are designed to extend the full length of the rake-head, and these bars may be of any appropriate size and material. Each tooth 32 consists of a metallic bar having the substantially rectangular form in cross-section shown by Fig. 5, and the end portions of each tooth are beveled or tapered, so as to produce the two points indicated in Figs. 2 and 3. Each tooth 32 is engaged at or about its middle by one of the sectional clamps, and as said clamps have interlocking engagement with the parallel bars it is evident that the series of teeth will be secured at their middles.

Each clamp consists of the members 33 34, one form of the clamp being shown more particularly by Figs. 4, 5, and 6. Each member of the clamp is cast in a single piece of metal substantially in the form shown by the detail view in Fig. 6 of the drawings, and said clamp member is provided on its inner face with the longitudinal anges 35 36. The flanges 35 36 of each clamp are disposed parallel, so as to form an intermediate groove or space 37, and said flange 35 is widened at one end,.as at 35, so as to form an abutment 38, while the companion iange 36 of the member is widened at the other end, as at 36a, thereby forming another abutment or shoulder 39. Each member of the clamp is provided on its outer face with the transverse ribs 40 and with the longitudinal rib 41.

IIn applying the two-part clamp to the parallel bars 30 31 of the rake-head suitable grooves 42 are cut in the opposing faces of the bars and the members 33 34 of the clamp are adjusted across the inner faces of the bars and in positions for the ribs 41 to enter the grooves 42, while the transverse ribs 40 of said clamp members will embrace the top and bottom edges of the bars, as clearly shown by Fig. 4. The members 33 34 are applied in reversed positions to the bars 30 31 in order that the active inner edges of the iianges on said members will bear against one another and the abutments or shoulders 38 39 will have the interlocking engagement represented more clearly by Fig. 4. The bars 30 31 are drawn firmly upon the members of the clamp by means of the screw-bolts 43, two of which are passed through said bars on opposite sides of each clamp, as clearly shown by Figs. 4 and 5. These bolts serve to draw the bars toward each other and to press the members of the clamp firmly upon the edge portions of thev double-ended' tooth 32. The members of the clamps are interlocked together and to the bars 30 3l by the engagement of the ianges and the ribs, and by interposing the tooth 32 within and between the members of the clamp the parts are prevented from lateral as well as endwise separation. The tooth is so firmly gripped in the clamp that it cannot become displaced in any direction; but in the event of breakage of any tooth the bolts can be loosened and the members of the clamp separated, so as to permit the Withdrawal of a broken tooth and its replacement by a new tooth.

The rake-head thus far described is loosely mounted in the bearings 29 of the rake-frame, and said rake-head is equipped with two pairs of arms 44 45, said arms being braced by the stays 46. In the position of the rake shown by Figs. 1, 2, and 3 the forwardly-extending arms 44 are engaged at their front ends with the bent ends 2la of the latch-bolts, whereby the rake-head is held firmly in a position wherein its teeth 32 are inclined slightly in an upward and rearward direction.

In the operation of the machine it is drawn across the fields, and the lower portions of the double-ended teeth serve to drag or rake the cut. stalks until a certain quantity of stalks shall have accumulated. At this time the operator presses on the lever 26, so as to pull the rod 24 in a forward direction and against the energy of the spring 23, thereby turning the trip-shaft 18 and making its crank-arms 19 pull the latches 21 forwardly. This operation of the latches disengages the hookshaped ends 21a thereof from the arms 44, thus releasing the rake-head and permitting it to turn or rotate for a half-revolution within the bearings 29, whereupon the rake is reversed, so that the other pair of arms 45 will engage with the bent ends of the latches 21, and the rake will then become locked in another active position.

In Fig. '7 of the drawings Ihave illustrated a slightly-modified form of one tooth-clamp. This clamp consists of the matching members having the mechanical features of construction heretofore described; but instead of Widening the flanges 35 36 for one-half the length thereof I prefer to only widen the flanges enough to secure the abutments or ICJ shoulders 38a 39, as will be clearly understood by reference to said Fig. 7.

The employment of the bar 8 at the rear end of the tongue and the loose connection of said bar to the axle nearits end portions enables the machine to be turned easily at the end of the row. The seat-spring 1l extends rearwardly from the tongue, so as to overhang the axle, and this arrangement of the seat serves to dispose a part of the weight of the operator in such a manner as to somewhat counterbalance the tongue.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In an apparatus of the class described, a rake-head consisting of longitudinal bars, a series of teeth, and a corresponding series of clamps, each clamp consisting of complementary members having interlocking connection one with the other and adapted to be secured rmly to the bars of the rake-head.

2. In an apparatus of the class described, a tooth-clamp comprising complemental channeled members provided in their opposing faces with projecting shoulders, said shoulders of the members being assembled inteinterlocking engagement, whereby the shoulders limit endwise displacement of the members relative to each other.

3. In an apparatus of the class described, a rake-head, consisting of longitudinal bars, a series of clamps interposed between said bars and each consisting of members which have interlocking engagement with each other and with the individual bars of said rake-head, and a series of teeth having individual engagement with the members of the clamps. A

4. In an apparatus of the class described, a tooth-clamp, consisting of complementary7 members provided with channels, and with recesses and shoulders on their opposing faces, said shoulders of one member arranged to enter the recesses of the other member, and the shoulders of the two members having engagement one with the other.

5. In an apparatus of the class described, a tooth-clamp, consisting of members each cast in a single piece of metal and having their active faces provided with longitudinal ribs and with tooth-receiving channels, the respective ribs being provided on their edges with the recesses and the shoulders ou each member, said members being assembled in reversed positions, and the shoulders of one member interlocking with the shoulders of the other member.

6. In an apparatus of the class described, a tooth-clamp consisting of members each cast in a single piece of metal and provided on its outer side with a transverse rib and with a longitudinal rib, each member being also provided on its inner face with longitudinal iianges which are enlarged and formed with the facing abutments or shoulders.

In Witness whereof Ihave signed my name to this speciication in the presence of two subscribing Witnesses.
