s EAT FOR CUMLTIVATORS.

SPECIFICATION forming part of Letters Patent N o. 704,515, dated July 15, 1902.

Application filed March '7, 1902. Serial. No. 97,146. (No model.)

To all whom, it may concern:

Be it known that we, BENJAMIN F. CLARK and WILSON SMITH, citizens of the United States, and residents of Cambridge City, in

the county of WVayne and State of Indiana, have invented a certain new and useful Im provement in Seats for Cultivators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form part of our specification.

The object of our invention is to provide a seat for a cultivator which when not in use may be pushed forward and out of the way. Our invention relates particularly to the manner of mounting the seat, and it is of such a construction and arrangement that when the operator of the machine desires to Walk he may rotate the seat forward, so that it may rest on the tongue, in which position it will be out of his road in case he walks behind the cultivator.

In the drawings, Figure 1 is a perspective view of a portion of a cultivator with our improved seat attached. Fig. 2 isa plan view of the arm supporting the seat. Fig. 3 is an inside elevation of a portion of the tongue, showing the manner of attaching the seatsupporting frame. Fig. 4 is a section of Fig. 3 on the line 4 4.. Fig. 5 is a detail view of one of the ends of the seat-supporting frame.

A is the usual tongue, secured in any convenient manner to the axle-frame B. The tongue A, as shown, is bifurcated at its rear 3 5 end, and the bifurcations project slightly behind the aXle-frame B and are provided with downwardly-hanging bars C at their inner sides, which are held in a vertical position by means of braces D, connecting the lower end of said bars C with the tongue A. The bar C is provided with notches 0, whose purpose will appear presently.

A swinging bar E is pivoted to the ends of the bifurcated tongue by means of a bolt pass- 5 ing through saidends and through the bar C, the bar E being held away from the bar C by means of a spacing-block e.

F is the seat, which is supported on the frame G, to which it is clamped in any con- 5o venient manner. The arm G is simply a bar any'required vertical position.

.the arm G at points near its ends, as seen in Figs. 2 and 5, the plate H projecting beyond the vertical leg of the angle-plate. The ver- 6o tical legs of the angle-plates H are of the same thickness as the swinging arms E and are at a distance froin the hookg equal to the width of the swinging arm E, so that the space It is of such a size that the swinging arm E may slide in it. The horizontal leg of the plate H is adapted to fit in the notches c in the bar C.

To attach our improved seat to the machine, the bolts are applied to the rearends of the bifurcated tongue, and the armsC and braces D are fixed in place. The bars E are then slipped into the spaces hat the ends of the'Y- shapediarm G, and the arms E are boltedin place, with the washers e separating them from the barsC, as seen in Fig. 2. Theends of the arm Gare then slipped down the bars E' untilthe horizontal leg of the angle-plate Hengages one of the notches c, in which position it is held, so as to support the party occupying the seat F. Then it is not desired to use the seat F, it is simply rotated forward, so as to rest upon the tongue A, the

arm E swinging about the bolt 6 as a center,

as seen in dotted lines in Fig. 3. The notches cfurnish a means for up-and-down adjustment of the arm C, so as to put the seat in The swinging arms E are booked in shape at theirlower ends, as seen at 70,l30 prevent the-Y-shaped arm from droppingcompletely. These hooks also perform the same function as the notches 0 when the arm G is moved to its lowest position.

We have described ourimproved' seat as atta ehed to a cultivator; but we do not wish to 5 limit ourselves to its use with a cultivator, as of course it is evident that it may beattached to a variety of implements, where its use would be of advantage, nor do we wish to be limited to the exact construction shown xoo and described, as it is apparent that this may be varied without departing from the spirit of our invention. For example, in some inachines it might be found thata single bar instead of the Y-shaped bar might be used, in

which case only one set of the arms 0 and E would be necessary.v In addition, the construction for forming the opening or slot h to receive the swinging arm E may be varied, and also the construction described for form ing the horizontal projections engaging the notches a may be replaced by any equivalent construction.

' Having thus described ourinvention, what we desire to claim as new and to cover by Lettersv Patent is 1. As a means for supporting a seat, vertical arms rigidly connected to the frame of the machine and provided with notches,swinging arms pivoted to said vertical arms, a Y- shaped arm supporting the seat at the rear and having its forward ends engaging said swinging arms and provided with a horizontally-projecting plate adapted to engage the notches in said vertical arm, substantially as and for the purpose described.

2. As a means for supporting a seat,a vertical arm rigidly connected to the frame of the machine and provided with notches, a swinging arm pivoted to said vertical arm, a second arm supporting the seat at its rear end, and having its forward end engaging said swinging arm, and provided with a horizontally'projecting plate adapted to engage the notches in said vertical arm, substantially as and for the purpose described.

3. In combination, a vertical arm rigidly connected to a frame and provided with notches, a swinging arm pivoted to said vertical arm, a second arm supporting the seat at its rear end and having its forward end bent into hook form and engaging said swinging arm, and a horizontal projection on said second arm adapted to engage the notches in said vertical arm, substantially as and for the purpose described.

4. In combination, a vertical arm provided I with notches and rigidly attached to the frame of the machine, a swinging arm pivoted to said vertical arm, a second arm provided with a seat at its rear end and with a vertical slot at its forward end through which passes the said swinging arm, and a horizontal projection on' said second arm adapted to engage the notches in said vertical arm, substantially as and for the purpose described.

5. In a cultivator, vertical arms provided with notches and rigidly attached to the frame, swinging arms pivoted to said vertical arms, a Y-shaped arm carrying a seat at its rear end and having grooves at its forward ends in which are located the said swinging arms, and horizontal projections on the forward ends of said Y-shaped arm adapted to engage the notches insaid vertical arm, substantially as and for the purpose described.

6. In a cultivator, vertical arms provided with notches and rigidly connected to the frame, swinging arms pivoted to said vertical arms, a Y-shaped arm having its forward ends located between said vertical arms and said swinging arms, and provided with angular extensions adapted to engage'said swinging arms,angle-plates secu red at the forward ends of said Y-shaped arm, with their horizontal legs in a position to engage notches on said vertical arms, plates forming a groove to receive said swinging arms and an adjustable seat mounted at the rear of said Y-shaped arm, substantially as and for the purpose described.

'7. In a cultivator, vertical arms provided with notches, swinging arms pivoted to said vertical arms, a bifurcated arm carrying a seat at its rear end and provided with hooks at its forward ends which engage said swinging arms, and horizontal projections at the forward ends of the bifurcations which are adapted to engage the notches of said vertical arms, substantially as and for the purpose described.

8. In combination, a vertical arm provided with notches, a swinging arm pivoted to said vertical arm, a bar supporting a seat at its rear end and provided at its forward end with a slot by means of which it may slide on said swinging arms, and also provided with a horizontal projection adapted to engage the notches in said vertical arm, substantially as and for the purpose described.
