`SP,EC!IFICA'JJION forming part of Letters Patent No. 291,453, dated January 1, 18i4` application inea May laissa. (No model.)

`.To all whom, it may concern:

Be a known that I, JOHN c. winmix., of

. Union City, in the 'county of Obion and State of Tennessee, have invented a new and Improved Broadcast Seedsower, of which the following is a full, clear, and exact description.

My invention consists of improvements in the construction of the gear-supporting frame,

and in the arrangements of 'the gears of a broadcast sower, consisting, essentially, of a hopper with a rotating cross-spout mounted on the upper end `of a staff connected with the gear-frame, and having a foot-rest to be supported in a strap carried overthe shoulder of the operator, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in

" which similar letters of reference indicate cordistributed, taken on the line fr c of Fig. 1.

For thegear-frame I provide two thin T- plates, of which a represents the head and b the stem, which plates are provided with the studs c and d on one side of the head c, and one head has the step-bracket c. Usingthe heads a of these plates for part of the staff, as well as the gear-frame, I connect said head at one end with the wood step-loiecef, and at the other end with the lower end of the wood section g of the staff, by bolting the plates to op; posite sides of said step and staff at h and i, so that said step and staff and also the studs c and d maintain the plates sufliciently apart to provide space in which to arrange the drivinggear, the outer ends ofthe parts b of the plates being curved, so as to :meet and form separating-studs, substantially like studs c, to

` be clamped together by bolt j, and said ends are materially widened, as shown at k, to form a practicable handle by which to manipulate the machine. Between the horizontal parts b of these plates I arrange a master toothed driving-wheel, Z, with a crank, m, for driving it, and between the vertical parts c of said plates, where they join plates b, I arrange a `spur-pinionm., and a bevel intermediate driver, o, on one shaft or pivot, to be turned by the driving-wheel. Z, gearing with the pinion n, and to turn the shaft p by the bevel-pinion q, said shaft being supported in the bracket e for a step, and extending up through the staff g and connecting with the cross-spout s, which is to be rotated thereby to discharge the seed out of its ends by centrifugal force, the seed being received into it from the nozzle t of the hopper u through the opening o in its upper side. For closing this nozzle to prevent the fall of the seed into the cross-spout when the machine is not in motion, and also to regulate the flow of the grain according to the 'speed of the machine, I now propose to have a gravityvalve, fw, located under the nozzle and connect'ed by an arm, sc, with a pivot, y, from which said arm projects outside of the cross-spout a suitable distance, and carriesacounterpoise, c, which hangs nearly vertical when. the machine is at rest and keeps the valve closed, but

i will rise by centrifugal force when the machine is set in motion and open the valve.

At c', I have arranged a plate which bows outward from the gear-frame above and below the projecting side of the counterdriver o for` a guard to the wheel and for a bearer to rest in the left armpit of the operator, while the step f rests in thepocket of a shoulderstra-p on the `left side of the wearer, and the handle 7c is grasped in the lefthand to press the bearer c into the armpit for securing the machine in position. The right hand is then used to work the machine by the crank m. The studs d are notched at the meeting ends for a bearing to the shaft p, and the staff g has a hole through its longitudinal axis for said shaft. This arrangement makes a simpler, more compact,

and better working machine than the pulley and-belt gear heretofore employed. makes a simple contrivance for the construction of the gear-frame, and the gravity-valve for letting on and shutting off the feed is more simple and positive in itsaction than the device heretofore used. l

Having thus described my invention, I claim as new and desire to secure by Letters Patent-` 1. The gear-frame and staff of a broadcast sewer, consisting of the T-plates a b, step f, and wood staff g, bolted together, the plates It also IOO having stop-studs c d 7c, also -step-stud e, and having thefpivot-bearings of the gear formed in them, substantially as described.

2. The stop-studs k of the parts b of the gear-frame plates, extended transversely to said parts b to form a handle for holding the machine when in use, substantially as described.

3. The combination, in the gear-frame and supporting-staff of abroadeast sower, of plates a b, handle 7c, and the guard a, substantially as described. Q

4. The combination, in the supporting and driving gear of a broadcast seed-sower, of the T-plates a b, bearing studs c d e, step f, staff g, driving-wheel Z, pinion n, bevel-Wheel o,

pinion q, and the shaft p, said shaft being arranged in the staff' gand having the cross` spout'attached to it, substantially as described.

5. The combination, with the revolving cross-spout s and nozzle t, of the valve w and bent lever x, pivoted to said spout, and having said valve and the counterpoise z secured directly thereto, the said lever extending through and to the outside of the said spout, 25 essentially as shown and described, and for the purpose set forth.
