D. FORSBERG GRASS CUTTER May 20, 1930.

Filed Oct. 8, 1928 INVENTOR. @Ml/[tsegd BY I A TTORNE Patented May 20, 1930 1 UNITED STATES DANIEL FORSBERG, OI BROOKLYN, NEW YORK GRASS CUTTER Application filed October 8, 1928. Serial No. 810,996.

This invention relates generally to farming tools and has more particular reference to a novel grass cutter.

- The invention has for an object the provision of a device-of the class mentioned which is of simple durable construction desirable in use and eflicient in action, and which can be manufactured and sold at a reasonable cost.

The invention proposes the use of a tubular body connected at its rear end with a longitudinal standard which is in turn connected by arcuate arms with a transverse standard. The front of the tubular body connects with a third standard arranged for supporting a stationary cutting bla e upon which a movable cutting blade is arranged. A shaft extends through the tubular body and is provided with a wheel on one end connected for reciprocating the movable blade, and provided with a gear at its other end connected for manual rotation. A rear body extension projects from the transverse standard and is provided with 'a handle.

It is pointed out that a cutter constructed according to this arrangement is very simple and easily constructed. Its operation is posltive and may be depended upon. The, handle provides a means for guiding the implement and the gear ma be manually rotated for causing the movab e blade to reciprocate.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and acompanying drawings, and

. to the appended claims in which the various novel features of the invention are more particularly set forth. I

The reference numeral 10 indicates generally a tubular body engaged at its rear end on a shoulder 11 integral with a longitudinal standard 12 formed with upper and lower arcuate standard arms 13. A transverse I standard 14 is formed with upper and lower arcuate transverse standard arms 15 arranged for aligning with the sides of the arms 13. The arms 13 are provided with arcuate slots 16 engaged by wing set screws 17 threadedly engaging in t e arms 15.

A rear body extension 18 projects from the transverse standard 14 and a handle 19 is connected on the rear end of this extension. A large bevel gear 20 is rotatively mounted in the transverse standard 14 and may be ro-- tated by reason of a handle 21 attached thereon. A bevel pinion 22 meshes with the bevel gear 20 and is fixed on a shaft 23 rotatively mounted in the longitudinal standard 12. This shaft 23 extends through the tubular body and is provided with a wheel 24 on its other end.

A third standard 25 is provided with a shoulder 26 upon which the front end of the tubular body 10 engages. The wheel 24 is positioned adjacent this third standard. An arcuate standard arm 27 projects from the third standard and is positioned alongside of an arcuate stationary blade arm 28 projecting from a stationary blade strip 29. The arm 28 is formed with an arcuate elongated slot 30 engaged by a wing set screw 31 threadedly connected with the arm 27.

Secured on the bottom of the stationary blade strip 29 and at the ends thereof are roller brackets 32. These roller brackets have bases 33 and right angle arms 34fintegral with the bases. Rollers 35 are engaged on shafts -er brackets.

36 mounted in the arms 34. Y A stationary blade 37 is firmly attached to the stationary blade strip 29: A movable blade 38 is positioned adjacent this stationary blade and on its topside and a movable blade stri 39 is firmly attached onto the movable bla e 38. The blade 38 and the strip 39 are formed with elongated apertures 40 engaged by screws 41 projecting from the stationary blade, the stationary blade strip, and the roll- These screws are stationarily fixed in the latter mentioned parts and are arranged for slidably connecting the movable blade and movable strip to the latter parts.

A connector pin 42 projectsfrom the movable blade strip 39 near one end thereof. A connector rod 43 engages upon the connector pin and upon a pin 44 eccentrically mounted on the wheel 24. A cover plate 45 is fixed upon the movable blade strip 39 by the screw 46.

In operation of the device the rollers 35 are rested upon the ground and the handle 19 is manually held in one hand while the operator turns the handle 21 with his other hand for rotating gear 20, bevel pinion 22 and the wheel 24. Rotation from the wheel is transmitted to the movable blade for reciprocating this blade by reason of the connector rod 43.

The stationary and movable blades are provided with pointed cutting ends 47 arranged for clipping the grass in the customary cutting ways. The wing .screw 31 may be loosened and the arms 27, 28 adjusted for changing theangle between the tubular body and the cutting blades of the device. The wing screws 17 maybe loosened and the arms 13, 15 adjusted for changing the relative aggle between the tubular body and the rear b y extension. Such, adjustments adapt the device toparticular users for purposes of convenience. I

While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention-as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is 1. In a ass cutter, a tubular handle with a longitudinal standard and a shaft running through both handle and standard, arms projecting from said longitudinal standard and formed with arcuate slots, other arms, wing set screws passing thru said arcuate slots and threadedly engaged in the latter arms, a transverse standard secured to the latter arms, a bevel gear rotatively mounted on the transverse standard and meshing witha bevel the aforementione inion on said shaft, and a handle rojecting rom the transverse standard capa le of as suming various an tubular handle. 2. In a grass cutter, atubular handle with a longitudinal standard and a shaft running through both handle and standard, upper and lower arcuate arms projecting from said longitudinal standard and formed with arcuate slots, other upper and lower arcuate arms, wing set screws passing thru said arcuate lar positions relative to slots and threadedly en aged in the latter I arms, a transverse stan ard secured to the latter arcuate arms, a bevel gear rotativel'y mounted on the transverse standard and meshing with a bevel pinionon said, shaft,

and a handle rojecting from the transverse standard capa le of assuming various angular positions relative to the aforementioned tubular handle. 7
