IMPROVEMENT lN GRAIN-REGISTERS.

Specification forming part of Letters Patent No. 179,136, dated June 27, 1876; application filed October 22, 1875.

To all whom it may concern:

Be it known that I,1\/IICHAEL SHAWVER, ot' the county of Clarke and State of Ohio, have invented certain Improvements in Tallying- Machines or Grain-Registers, of which the following is a specification:

My invention relates to that class of tallying-machines or grain-registers which are attached to thrashing-machines for the purpose of registering the number of bushels of grain or seed thrashed and measured as it passes through them.

My invention has for its object simplicity of construction, cheapnessof cost, ease of operation and attachment to the thrasher, and eertainty in correct registry, also facility for recommencing.

A small wooden case incloses the mechanism, which is operated by a switch-gate in an inclined spout passing under it. Two dialplates are seen upon the front of the case, one of which shows the number of half bushels of grain thrashed up to ten, while the other gives the number in hundreds.

Figure l is a front view of my improved tallying-machine. A portion of the face (in eluding part of the dial-plate) is shown broken or cut away to exhibit the interior mechanism.

A is the case, which is attached to the side ofthe thrashing-machine, its base resting upon the grain-spout D, which forms a part of the device. A (the great wheel) registers the number of bushels by hundreds upon the dial in front of it. B is a smaller wheel, having larger teeth, and asingle-toothed pinion, G, on its shaft, (under the small dial,) which meshes into the teeth of wheel A. O is a singletoothed wheel, which turns only partially around, so as to impinge against the teeth of wheel B, rebounding after each contact, and moving B one tooth each time. It has a cranklever, K, on the front end of its shaft, which is connected, by the small link or lever c, to the latch-lever Z. The latter extends across the spout D, being pivoted at its right end to the base of case A. ltis made thickest in the middle, forming an obtuse angle on its lower edge, so as to allow it to rise up when operated upon by the switch-gate E, passing under it from side to side. The latter is pivoted by its lower end in the middle of the open end of spout D. It is made of board, setin edgewise the same depth of the spout, and extends back un'der thelatch-lever l, as shown in the figure.

Both wheels A and B are provided with retaining-pawls, mounted upon springs. That of 1) projects downward from the upper left corner of case A, and meshes into the teeth of wheel A. The lower end of this pawl is prolonged, so as to be operated upon by the upper end of the reactionary lever c, which is pivoted upon a pin at its middle part, so that when its lower end is pushed in by the loose stud b, (which passes at this pointthrongh the case, its head projecting outside,) its upper end, lapping behind the prolonged end of pawl 19, throws it out of gear with the wheel.

vThe object of this device is to allow the; wheel A to be turned backward with its index to the point of beginning, when it is desired to recommence tallying.

In operating the machine the index-hands are first set at zero, the thrasher set in motion, and the grain passes through the spout D from rear to front from the conveyers. Two half-bushels are provided, and as soon as one is filled the switch-gate E is switched to the opposite side of the spout, cutting off the stream of grain and directing itinto the other half-bushel. the latch l, and the connecting or link lever c pushes up crank-lever 70, attached to the shaft of the rebounding single-toothed wheel 0, which turns to the right until its tooth moves the wheel B one notch, raising pawl 19, (which falls into the next notch,) and the index on the small dial marks one tally, or one halfbushel. The gate is then switched to the opposite side, marking as before, the wheel 0 rebounding after each movement. When wheel B has made one revolution and marked ten tallies, the single-toothed wheel 0 catches one of the teeth of wheel A, raising its retainingpawl 0, and moving it one notch.

The teeth of the wheels and their pawls are all V-shaped-z'. 6., their faces have equal angles, and are beveled to an edge-as othershaped teeth would not operate in the same manner with the single-toothed wheel 0.

The shaft of the great wheel A should be extended out of the back of the case, orit may be provided with a post for a key, by which it The movement of gate E raises can be turned backward in beginning, when the pawl 9 is raised by the lever 0 with stud I). To lessen the cost of construction, I make the wheels and pawls of wood, hard wood being preferable. Any ordinary mechanic can construct the device.

The Front of the case is entirely tight, and the whole is excluded from dust, and from being tampered with, by inclosing it in an airtight box, which is readily attached to the thrasher.

I am aware that tallying-machines registering by cloclrgearing are not new, and I do not wish to be understood as claiming the same as any part of my improvement.

In all ordinary registers or tallying-machines, where the movement is transmitted from a cut-01f valve or switch-gate to the gearing, the tooth, pin, or cog, or other projection, after contact with the tooth of the wheel which marks the tally, passes by said tooth, either in full or partial rotation of said pin or cog.

not claim it; but the rebounding single-toothed wheel 0, by which the machine is operated, as well as the lever 0, with its operative stud I), in combination with the pawl p and the gearing shown, I believe to be new.

Such movement is old, and I do' I therefore claim- 1. In eombinatiom in a grain-register or tallying-machine, having a case, A, provided with two graduated dials and wheels, A and B, having teeth with equal angles, (the latter with its single-toothed wheel 0, mounted on the same shaft,) and their respective retaining-pawls p and 19, constructed as specified, the rebounding single-toothed wheel 0 its connecting-lever c, crank-lever 7c, latch l,

switch-gate E, and spout D, as and for the MICHAEL SHAWVER. Attest:

EZRA DAVEE, B. G. CONVERSE.
