JOHN FREDERIC PORTER, OF MOUNT \VASHINGTON, KENTUCKY.

GRAIN MEASURE, REGISTER, AND SACKER.

SPECIFICATION forming part of Letters Patent No. 327,718, dated October 6, 1885.

Application filed April 16,1885. Serial No. 162,457. (Model) To all whom, it may concern.-

Be it known that I, J OHN FREDERIC Pon- TER, of Mount \Vashington, in the county of Bullitt and State of Kentucky, have invented new and useful Improvements in a Combined Grain Measure, Register, and Sacker, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of one of my improved grain measures, registers, and sackers, parts being broken away. Fig. 2 is a sectional front elevation of the same. Fig. 3 is a sectional side elevation of the same. Fig. 4 is a sectional elevation of the register-casing, showing the hinged plate for holding the register in gear.

The object of this invention is to provide machines for measuring and registering grain as it comes from the discharge spout of a grainseparator or other discharge-spout, and which shall be simple in construction and convenient and reliable in use.

The invention relates to a combined grain measure, register,and sacker, constructed with a casing having open front and provided with a dischargeopening in its bottom, and within which is pivoted a wheel divided into compartments by radial partitions, and having in the bottoms of its compartments dischargeopenings closed by trap-doors provided with rollers at their free edges, the said wheel receiving grain through a feed-hopper attached to the top of its casing, whereby the grain can be measured and discharged from the machine by turning the said wheel. Vith the measuringwheel and its casingis connected a worm meshing into the teeth of a worm-wheel provided with a long tooth engaging with a gearwheel and tripping the pawl that holds the said gear-wheel in position, the said wheels being pivoted to a frame and provided with index-fingers, whereby the amount of grain passing through the machine is registered. The casing containing the registering mechanism is provided with a plate to be interposed between the end of the said casing and the end of the frame carrying the said registering mechanism to hold the said mechanism in gear, and which can be readily removed to allow the said mechanism to be thrown out of gear, as will be hereinafter fully described, and then claimed.

A represents the bottom of the machine, which is supported upon a frame or support, B, of such a height as the place where the machine is to be used may require, and as will allow sacks to receive the grain to be readily placed beneath the said machine and removed therefrom.

G is the casing, which is secured to the bottom A and extends around and covers about three-fourths of the said bottom.

D is the measuring-wheel, which is divided into four (more or less) compartments by radial partitions E. The compartments of the wheel D have discharge-openings D in their bottoms, and are made hopper-shaped around the said discharge-openings, so that the grain will flow out readily. The discharge-openings D are closed by trap-doors F, which fit into rabbets in the lower side of the bottom of the wheel D, are hinged at one end to a partition, E, or the bottom of the said wheel, and have small rollers G pivoted to their free ends to roll along the bottom A of the machine, the said rollers G being made of such a size as to hold the said doors F tightly closed until the said doors come over the discharge-opening A in the said bottom A, when the said doors drop and discharge the grain through the said opening. The edge of the bottom A, at the forward side of the dischargeopening A, is beveled, as shown in Fig. 2, so that the doors F will be readily raised into place as the wheel D moves onward.

To the lower side of the bottom A, at the opposite sides of the opening A, are attached rabbeted cleats II, to receive the grooved upper end of the discharge-spout I, through which the grain passes into the bags, and which may be provided with hooks J, to receive and support the said bags.

To the center of the lower side of the wheel D is attached a pivot, K, which revolves in a socket in the bottom A.

To the partitions E, at their point of meeting, is rigidly attached the lower end of the shaft L, which passes through and revolves ing M is secured aglass plate,

in a bearing in the top of the casing C. The upper end of the shaft L revolves in a bearing in a bar attached to the top of the casing M, attached to the top of the casing O, to receive the register mechanism.

Upon the shaft L is formed a worm or screw,

, N, the thread of which meshes into the teeth of theworm-wheel O, pivoted to a frame, P, placed within the casing M.

To the worm-wheel O or its shaft is attached a long tooth or wing, Q, which at each revolution of the said wornrwheel O engages with a tooth of the gear-wheel R and turns the said gear-wheel through the space of one tooth.

The gear-wheel R is locked in place by a pawl, S, pivoted to a rod, T, attached to the frame P. The pawl S is held down by its own weight, and is provided with a downwardlyprojecting arm, U, against which the tooth Q strikes just before it engages with the gearwheel R and raises thepawl S out of gear with the gear-wheel R, and then turns the said gearwheel through the space of one tooth. As the tooth Qleaves the tooth of the geanwheel R it also leaves the arm U of the pawl S, when the said pawl drops into place and again locks the said gear-wheel.

To the forward journals of the wheels 0 R are attached index-fingers V W, which move along scales of division-marks upon the front of the frame P to register the movements of the wheel D, and consequently the amount of grain that has passed through the said wheel.

In an opening in the front wall of the cas- X, through which the positions. of the index-fingers V W can be readily seen.

The frame P is made a little shorter than the casing M, so that it can have a slight longitudinal movement within the said casing to throw the worm-wheel 0 into and out of gear with the worm N. The frame P is locked in place when the worm-wheel O is in gear with the worm N by a plate, Y, interposed be tween the outer ends of the frame P and casing M, and which for convenience is pivoted at one end to the said casing M, so that it can be readily swung into and out of place.

The grain is introduced into the machine through a casing or feed-hopper, Z, attached to the top of the casing G at the inner end of the casing M, and which has an opening in its top to receive the end of the spout of a grain-elevator, orotherconducting-spout. The tops of the casings M Z are loose, so that they can be readily removed to give access to the interior of the said casings.

In an opening in the front of the casing Z is secured a glass plate, a, so that the attendant can readily see when a compartment of the wheel D is full, and can thus know when to turn thesaid wheel D to bring the next compartment of the said wheel beneath the hopper Z and discharge the contents of the full compartment into the bag.

The wheel D is designed to be turned. by hand.

To supports attached to the lower side of the top of the casing O, at its front edge and the middle of its rear part, are pivoted three small rollers, 12, to rest upon the upper edge of the rim of the wheel D, or upon an inwardlyprojecting annular flange, c, attached to the said edge, so that the said wheel will be held down to its seat and made to revolve easily.

To the upper side of the bottom A is attached a spring, d, which, as the wheel is revolved and comes into proper position for a full compartment to discharge its contents and an empty compartment to receive grain, enters a recess, 6, in the bottom of the said wheel, and thus serves as a guard or check to prevent the said wheel from being turned too far or not far enough.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a combined grain measure, register, and sacker, the combination, with the measuring-wheel D and its casing A O, of the worm N, worm-wheel 0, having longtooth gear-wheel R, turned by the said long tooth, the pawl S, locking the said wheel R and provided with an arm, U, to be engaged by the said long tooth, the index-fingers V WV, attached to the journals of the said wheels, and the frame P, substantially as herein shown anddescribed, whereby the amount of grain passing through the machine is registered, as set forth.

2. In a combined grain measure, register, and sacker, the combination, with the casing M, attached to the cas ng of the measuring wheel, and the frame P, carrying the registering mechanism, of the lockingplate Y, substantially as herein shown and described, whereby the said mechanism will be held in gear and can be readily thrown out of gear, as set forth.

3. The combination of the base-plate, the wheel having compartments provided with trap'doors hinged at one end and provided at their opposite or free ends with anti-friction rollers, the casing O, and anti-friction rollers journaled to the casing and bearing upon the rim of the wheel, whereby the said wheel has anti-friction bearings above and below, substantially as set forth.
