REGISTER FOR GRAIN-MEASURES.

SPECIFICATION forming part of Letters Patent No. 473,465, dated April 26, 1892.

Application filed June 3,1891.

To .fz/ZZ whom, t may concern.-

Be it known that we, JOHN A. JAMES and DAVID J Anus, citizens of the United States, residing` at Coffeyville, in the county of Montgomery and State of Kansas, have invented certain new and useful Improvements in Registers for Grain-Measurers, of which the following is a specification, reference being had therein to the accompanying drawings.

Ourinvention relates to an improvement in registers for grain-measurers; and it consists in the certain peculiar features of construction and arrangement of parts more fully hereinafter described, and definitely pointed out in the claims.

The object of our invention is to provide an improved automatic registering device especially adapted for use in connection with grain measurers or weighers, which is very compact in its structure and precise in its operation. This object we accomplish by the construction illustrated in the accompanying drawings, in which like letters of reference indicate like parts in the several views, and in which- Figure l is a front elevation showing the front of the casing removed. Fig. 2 is a central vertical section. Fig. 3 is an elevation of the dial-plate and hands or pointers. Fig. et is a detail perspective of the actuatingwheels, and Fig. 5 is a detail perspective of the escapement and governing spring.

In the drawings, A represents the casing, and B the dial-plate formed either integral therewith or separate. This dial-plate is circular and is formed with three concentric circles, in which numbers are placed, the first series running from zero to ten, the second series from ten to one hundred by tens, and the third series from one hundred to one thousand by hundreds.

C is a ratchet-disk, having an opening c in the center thereof and provided with a hub c', on which is sleeved a hand c2. On the opposite face of the disk and flush with the front face of one of the ratchet-teeth is secured a projecting arm c3. The upper end of this arm is extended outto one side, so that it will escape the arm ofthe pawl passing over the wheel, as hereinafter described. Secured to the front face of the disk C and sleeved on the hub is a washer c4.

Serial No. 394.919. (No model.)

D is a cog-wheel having an opening in the center thereof, in which is rigidly secured a hollow shaft d, which passes through the opening c of the ratchet-disk and on the end of which is sleeved a hand d of a length less than the hand c2. Sleeved on the shaft d, between the ratchet-disk and the cog-wheel D and secured to the latter, is a washer d2.

F. is a wheel rigidly secured on the shaft e, which is secured in suitable bearings on the front and rear of the casing. The forward end of the shaft e passes through the hollow shaft d and has secured thereto a pointer e', which is of a length less than the length of the other two pointers. This wheel E also has a washer c2 secured thereto and which is sleeved on the shaft c.

e3 are pins, preferably ten in number, secured at equal intervals on the face of the wheel F., near the periphery thereof.

F is a cog-wheel, similar to the cog-wheel D and meshing with the same, secured on the shaft f, which is journaled in bearings in the front and rear of the casing. At equal intervals around the face of the wheel F and near the periphery thereof is a series of pins f', preferably ten in number. These pins are engaged by the projecting arm c3 of the ratchet-disk, the pins e3 being in turn engaged by the projecting arm fg, secured rigidly on the rear face of the cog-wheel F.

G G are suitable flat springs secured at one endto the inside of the casing, the other ends engaging the wheels F and E at any suitable points, which act to prevent movement of said Wheels when they are not actuated by the operating mechanism.

H is an escapement or pawl formed with the shank 71, which extends up' through a suitable opening L in the top of the casing, and the curved spring-arms h2 and h3. These spring-arms h2 and h3 are in the form of Wire loops, the ends of which are bent up and adapted to iit over the periphery of the ratchet-disk C and engage the teeth thereon, as shown in Figs. l and 5. These arms are mounted in the shank, so that the lower end of the arm h2 will be below that of the other, and the shank is placed at a point to one side of the axis of the wheels, so that the arm h2 will be in contact with one of the teeth of the ratchet-disk, while the other arm is below the IOO Y ratchet-tooth. It will be understood that the pointers, in connection with the different wheels, operate around the dial-plate of the f front of the casing.

The operation of our improved register is as follows: The shank h of the escapement H is connected with a suitable oscillating crankarm or other means on the machine in con-y which push the disk down on one side and lift it up on the other side as theshank is moved up and down. The rotation of the ratchet-disk C causes the rotation of the cog- Wheel F, through theprojecting 'arm c3 and the pins f on the wheel F, with which it engages after it hascompleted `its revolution, which in turn causes the revolution of the cog-wheels D, with which it meshes, and the wheel E, through thetprojecting arm f2 on the wheel F, and the pin e3, the wheel E moving one space to every revolutionof the wheel F.

From the above description it will be seen that for every Vten revolutions of the disk C the cog-wheels D and F revolve once, and for every ten revolutions of the cog-wheels D and F the wheel E is revolved once. Thus the pointer connected 'with the disk C, the cogwheel D, and the wheel E count by units, tens, and hundreds, respectively, in their movement on the dial-plate.

4As described, our device registers as high as one thousand; but we wish it to be understood that it can be made to register either a larger 'or smaller amount by slight changes in the sizes of the wheels -and arrangement of the pins. When a certain number has been registered and it is desired to commence a new series, the device has to be reset, which can be easily accomplished by removing the pawl and turning'the pointers back.

We are aware that many minor changes in the construction and arrangement of the parts of our devicecan be made and. substituted for those herein shown and described wit-hout in theleast departing fromthe nature and principle of our invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a register, the combination, with the casing aud dial-plate, of a ratchet-disk having an openin g in the center thereof and a hub on oneside, a pointer sleeved on the hub, a projecting arm on the opposite side of. the disk, a cogwheel having an opening in the center thereof, a hollow shaft rigidly secured in said opening and passing through the opening in the ratchet-disk, a pointer sleeved on the outer end of the hollow shaft, a wheel in the rear of the cog-wheel having an opening in the center thereof, a shaft rigidly secured in said opening and journaled in bearings in the front and rear of the casing, pins on the front face of the wheel near the periphery thereof, a pointer on the outer end of the shaft, a cog-wheel below the other cog-wheel and meshing with the same, a shaft jonrnaled in bearings in the front and rear of the casing and uponvwhich said cogf wheel is secu red, pins on the front face of the cog-wheel near the periphery thereof, a -proj ectin g arm rigidly secured on the rear face of lthe cog-wheel, and a pawl engaging with the teeth of the ratchet-disksubstantially asglescribed.

2. In a register, the combination, with the casing and dial-plate, of a registering mechanism within the casing, consisting of a ratchetwheel formed with an arm near its periphery and a central hub, acog-wheel mounted on a hollow shaft passing through the hub onthe ratchetdisk,'a Wheel in the rear of thecogwheel provided with a series of pins ou its side, a shaft ou which the same is rigidly mounted extending through the hub and hollow shaft on the outer wheels, bearings for the shaft inthe casing, `a cog-wheel below the other cog-wheelengaging the pinson the rear wheel, a vertically-movable pawl having arms engaging the oppositesides of ithe ratchetwheel, and pointers on the outer ends iof the hub, hollow shaft, and shaft, substantially'as described.

3. In a register, the combination, with a casing, a dial-plate, andr a ratchet-disk, of a pawl consisting of a verticallysmovable shank located to one side of the axis'of therdisk, and

curved spring-Wire arms lsecured Ain the-end of the shank, looped at their lower ends, and extending down on opposite sides of the lratchet-disk and engaging the teeth on the same, substantially as described.

In testimony whereof we affix our signatures 'in presence of two witnesses.
