- IMPROVEMENT IN HARVESTER-RAKES.

Specification forming part of Letters Patent No. 170,435, dated November 30, 1875; application filed July 21, 1875.

To all whom it may concern:

Be it known that I, SAMUEL F. ORANsToN, of Lansingburg, in the county of Rensselaer and State of New York, have invented an Im provement in Harvester-Rakes; and I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings making part of this specification.

' The object of my invention is to provide a .protector guard or cover for the head of harvester-rakes, in order that straw, grain, dirt, or other substances may be prevented from falling upon or entering into the mechanism of the rake-head and the mechanism immediately contiguous thereto.

Figure I is a perspective view of so much of a revolving harvester-rake as is necessary to show the manner of applying my improvements. Fig. 2 is a perspective view of a barvester-rake having my improved rake-head attached. Fig. 3 is a plan view of my rakehead cover as cut from pliable or textile material.

Similar letters of reference denote corresponding parts in all the figures.

Inthe accompanying drawings, B B B B represent the arms of a revolving harvesterrake, A, which rake is of the ordinary con struction, and will not, therefore, be further described. 0 represents the cover or guard for the rake-head A. This cover is made by cutting from a circular piece of canvas, or othersuitabie textile or pliable material, sectors, as shown at m x .70 a; in Fig. 3. Openings y y y y are also cut, to allow the introduction of the rake-arms B B B B. After the sectors are so cut or removed the edges .1; :20 a: are brought together and joined by means of laces, straps, or buttons, or other suitable fastenings. The cover then assumes a hood-shaped contour, 0, as shown in Fig. 2.

I do not limit my invention to a guard or cover formed by cutting sectors from a oircular piece of pliable fabric. It may be woven or formed in one entire body. I

In order to support the cover, and protect it from becoming entangled in the mechanism of the rake-head, I attach to the under side of the rake-arms eyes E E E E, through which I pass a hoop, H, of iron, wood, or other suitable material, thus encircling the arms of the rake. The ends of the hoop, when brought together, are fastened by means of twisting the ends together, or by means of an in tervening or clamping tie, or other suitabledevice.

They may also be fastened by means of a tubular or socket joint, thus forming practically an unbroken or continuous hoop. The size of the eyes E E E E and the length of the hoop H are so regulated and adjusted as to allow the free and proper working of the rake-arms B B B B in their respective and successive positions. 1 The eyes and hoop being thus attached to the rake-arms, the hood-shaped cover or guard G is placed over and around the rakehead A by passing the arms BB B B through the openings y y y y. The guard or cover is so formed as to cover and protect completely the mechanism of the rake-head, and exclude therefrom all grain, grass, straw, or other extraneous matter which might be lodged on or enter into such mechanism, the cover being fitted tightly around and hung down between the rake-arms in such a manner as to accomplish that purpose. The openings y y 3 y in the cover are placed at such distance from each other as to allow the cover-to be slack or loose between the rake-arms, so that it may not interfere with or constrain their working.

Havin gdescri bed my invention, whatI claim as my invention, and desire to secure by Letters Patent, is-

.1. The cover or guard 0 formed of a pliable fabric, and to protect the head of a harvesterrake, operating substantially as described.

2. The combination of the cover 0 and hoop H, supported substantially as described.

3. The hoop H, supported on the arms of a harvester-rake, substantially as described.

4. The combination of the cover G, the hoop H, and the rake-arms B B B B, constructed and arranged substantially as described.
