UNITED STATES JOHN w. srnowenrnen, or CORTLAND, NEW YORK.

IMPROVEMENT IN SEEDlNG-MACHINES.

Specification forming part of Letters Patent No. 136,107, dated February 18, 1873.

To all whom it may concern:

Be it known that I, JOHN W. Srnow- BRIDGE, of Cortland, Cortland county, New York, have invented certain Improvements in Plaster and Seed Sower, of which the following is a specification:

My seed or plaster sower may be attached to any vehicle moved on wheels.

Figure 1 shows the machine attached ready I for use; Fig. 2, the inside of the hopper and slide attachment; Fig. 3, the distributer, with fans for spreading the plaster or seed.

W is the wagon; a a a, the braces or arms screwed to the rear end of the wagon with screws or other convenient manner. These braces are of such strength and form as to support the driving-wheels and the distributing apparatus. Through the extremity of thc'braces a revolves the shaft b, which also rests and revolves in the head of the brace a. a, which isv formed with a socket to receive the end of the shaft. The wheel 0 is upon, attached to, and revolves with the shaft b. The wheel 0, set in motion, drives the wheel E, whic h, in its turn, rests. upon and-revolves with the; upright shaft E, shaft E resting in a socket in the extremity of the upper arm of thebrace a. Thisshaft extends up through the cap m into the hopper N.

Just below the cap w, and between that and the wheel E, the distributer is securely fixed to the upright shaft and rotates with it. At the extremity of the shaft b and beyond the brace a, is a pulley, Z. From this pulley a cord or belt is extended to and is attached to another pulley, h, fixed to the inside of .the wheel of the wagon W, so that itTIlftributer.

The distributer is made with a hub, S, with concave arms, 9 g, extending from the hub and beyond its edge some four inches. The

arms may be attached extending outward direct or slightly depressed. The number of these arms is not imperative. It is found in operation that six is a convenient number. Through'the stem of theupright shaft E, extended up into the hopper, is insertto revolve within the hopper. This should be sufficiently strong to break up any lumps in the plaster or seed, and. to keep the orifices cleared of all straws or other foreign elements. Slides 0 o are adjusted to the side of thecap w, and constructed to pass under the side of the hopper and cover the holes 1) p when the distributor is not in motion.

To fix the flow of seed or other substance, I provide a third slide with smaller holes than 10 p. This slide is drawn out, and shows an orifice at 2. There may be graded slides, or one slide only. When one is used it may be drawn or set according to a'scale marked on the bottom of the hopper, so that by set ting this slide a definite amount of grain will be regulated. When scaled slides are used it is only necessary to fix in place the one graded to the article to be sown, and a definite amount per acre in either case will be obtained.

The amount of grain is regulated and the slide 2 adjusted by means ofa lever attachment, 3, working in a brace-standard, 4. The lower end being attached to the extreme end of the slide 2, by a movement of the handle 3 the slide is instantaneously adjusted at any desired point of regulation.

The operation of my invention is simple: The wagon is set in motion the pulley or belt attachment revolves shaft b and wheel 0, which, in turn, drives the upright shaft and the distributer. The plaster or other substance is turned into the hopper, slides or slide drawn, and the plaster drops upon the distributer, is received by the fans, and spread The cut-off 0 0 gives entire 0011- broadcast. trol to the operation, and by adjusting these and the slides 2, or by using either separately, the quantity can be accurately regulated.

The form and dimensions of the parts of my machine are adapted to suit the convenience of the wants of the user. They should be of sufficicnt strength to give firmness and stability, and for the most part are made to best advantage of cast-iron.

The advantages of my invention are its simplicity, durability, andefficiency. The substance to be spread can be taken into the wagon and the work carried on with great ease and dispatch.

Vv'hatlclaim as myinvention, and desire to whereby it can be attached to and detached secure by Letters Patent, is; from the rear end of a wagon'or cart, as set A broadcast seed-distributer, consisting of forth. the shaft b provided with the pnlley Z and JOHN W. STROWBRIDGE.

wheel c, the upright shaft E provided with the pinion E, radial grooved arms g, and Witnesses:

agitator 1, and the hopper N, all construct- ARTHUR HOLMES, ed and arranged. substantially as described, JOHN SEARS.
