SPECIFICATION forming part of Letters Patent No. 602,513, dated April 19, 1898.

Application filed March 2 '7, 18 9 6 T0 all whom t may concern:

Be it known that I, HENRY W. MORGEL, a citizen of the United States, and a resident of Brazil, in the county of Clay and State of Indiana, have invented certain new and useful Improvements in Lawn-Mowers, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to lawn-mowers; and the object thereof is to provide an improved lawn-mower which is simple in construction and operation and which is also comparatively inexpensive; and with this and other objects in view the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which- Figure l is a plan view of my improved lawn-mower; Fig. 2, a central vertical section, and Fig. 3 a front elevation, thereof.

In the practice of my invention I provide a suitable frame which comprises side bars A and a rear bar B, and the side bars A are bent downwardly, as shown in Fig. l, and extended forwardly, and said side bars are connected at the end of the downward inclination by a yoke C, the ends of which are securely bolted thereto at C2, and also by a curved crossbar D, the ends of which are bolted to the side bars A at d.

The main axle E of the machine is connected with the rear portion of the side bars A and is provided with suitable bearings or boxes E2, and the main drive-wheels F are mounted on the ends of the axle E, and each of said wheels is provided on its inner side with a pivotedpawl F2, each of which operates in connection with a corresponding ratchet-wheel F2, one 0f which is rigidly secured to each end of the axle inside of the main drive-wheels F.

Mounted beneath the forward extension of the side bars A is a-supplemental shaft or axle G, on which are mounted small wheels g, which are adapted to support the-forward portion of the machine and to hold the frame thereof in the desired position, and the for- Serial No. 585,042. (No model.)

ward extension of the frame A is provided with a cutting-blade H, which is provided with cutting sections or teeth 7L, and the blade I-I is rigidly secured to the frame, and placed upon the blade H is a movable blade K,which is also provided with cutting sections or teeth k and with a longitudinal slot 7a2, and placed longitudinally thereover is a bar 7a2, which is held in place by bolts 154, which pass therethrough through the slot k2 and through the stationary blade and the side bars A, and the obj ect of this construction is to provide means for holding the movable blade K in place, while permitting the free movementthereof.

Each end of the movable blade K is provided rearwardly of the slot 7a2 with vertical standards L, which are rigidly secured thereto andv -which are arranged at each side and provided lwith jaws between which are pivoted pitmanrods M, which are slotted at their inner ends, Y*

as shown at M2, which engage with a crank fm on a wheel 'm2, which is mounted on a shaft m2, which passes through bearings m4, secured to the yoke C of the main frame, and similar bearings m5 on the bar D, and the rear end of which is provided with a beveled gear wheel or pinion O, which is operated by a large beveled gear-wheel O2, which is rigidly secured to the main shaft E of the machine.

Secured to the opposite sides of the frame of the machine, immediately over the main shaft, are inwardly and upwardly directed arms P, the upper ends of which are provided with segmental cross-heads P2, in which are formed segmental slots through which passes a bolt P4, and the bolt P4 passes through the lower end of' a handle-bar R, the lower end of which is pivotally connected with the arms P by a bolt R2, and by means of the pivotal connection of the handle-bar at R2 and the segmental cross-heads P2, through which the bolt P4 passes, the position of the handle-bar may be adjusted at will.

I also provide a cover or cap S, which is composed of sheet metal and which is pivotally connected with the bolt R2 and which is adapted to be swung down over the frame and the operating parts of the machine, and it will also be observed that each of the pawls F2 is provided with a spring F4, which are secured to the wheels F, and the operation will IOO be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statement thereof.

It will be understood that when the machine is shoved forward the wheels F and the shaft E revolve together, and the shaft E revolves the gear-wheel O2, and by means of the gear-wheel O2 the shaft m3 and the wheel m2 are also rapidly revolved, and this revolution of the wheel O2 operates the movable blade K and causes it to move rapidly back and forth over the stationary blade H. The shaft E is revolved by the main wheels F through the agency of the pawls F2, which operate in connection with the ratchets F3, and in the backward movement of the wheels F they revolve freely on the shaft E. It will therefore be observed that the machine may be pulled back- Wardly without operating the blade K and that whenever the machine is pushed forwardly the blade K will be operated, as hereinbefore described.

The rear corners of the blade K are cutaway, as shown at S, in order that said blade in the operation thereof will not strike or interfere with the wheels C, and the rear corners of the stationary blade H are similarly cut away, and said stationary blade is carried backwardly, and the yoke C and said blade are together bolted to the side bars A.

By the use of the double pitman-rods slotted at the inner end it will be seen that the reciprocating blade is always operated by a pull on the pitman-rods and never by a push, and the said rods are so constructed that one of said pitman-rods is engaged by the crank m during one half of the revolution of the wheel m2 and the other pitman-rod will be engaged by the said crank fm during the other half of the revolution thereof.

My improved lawn-mower is simple in construction and operation and perfectly adapted to accomplish the result for which it is intended, and my invention is not limited to the exact form, construction, combination, and arrangement of the various parts thereof, as herein described, and I reserve the right to make all such alterations therein and modiications thereof as fairly come within the scope of the invention.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a lawn-mower of the character described, a stationary cutting-blade, a movable blade mounted thereover, standards secured to said movable blades at each end thereof, pitman-rods connected with each of said standards, the inner ends of said pitman-rods being provided with longitudinal slots and both being mounted on the same crank and being so proportioned that one of said pitman-rods will be engaged during one half of the revolution of said crank and the other pitman-rod will be engaged during the other half of the revolution of said crank, substantially as and for the purpose described.

2. The herein-described lawn-mower comprising two drive-wheels, a main shaft on which the said drive-wheels are mounted, a large beveled gear-wheel mounted on said shaft, a ratchet-Wheel mounted at each end of said shaft and a pawl mounted on each of the drive-wheels adapted to engage said ratchetwheels, a shaft revolubly mounted in the frame which is mounted on said axle, and provided at the rear end with a beveled gear adapted to engage said beveled gear on the shaft of the drive-wheels, and the outer end being provided with a crank to which is secured a crank pin, a movable cutterbar mounted in the forward end of the frame and provided at each end with an upwardly-directed standard,pitmanrods pivotally mounted in each of said standards each of which is provided at the inner end with a longitudinal slot and each being mounted upon the said crank-piu, substantially as and for the purpose described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 23d day of March, 1896.

HENRY XV. MORGEL.

FRANK A. HORNER, JOHN O. KAEHLER.
