UNITED STATES PATENT Erica,
LYMAN BAKER, OF NEWBURY, NEYV HAMPSHIRE.
IMPROVEMENT IN SPRING RAKE-ATIEETH.
Specification forming part of Letters Patent No. 6,424, dated May 8, 1849.
.To all 'whom-fit 'may concern:
Be it known that I, LYMAN BAKER, of Newbury, in the county ot' Merrimack and State of New Hampshire, have invented a new and useful improvement in the mode of applying spring-teeth to the rake-head of a horse-rake or hand-rake; and I do hereby declare that the same is fully described and represented in the following specification and accompanying drawings, letters, figures, and references thereof'.
Ot' the said drawings, Figure l is atop view of my improved spring-tooth and socket. Fig. 2 is a side elevation of it. Fig. 3 is a longitudinal and vertical section of it and the rakehead. Fig.4 is across-section ofthe socket and part of the rake-head.
My invention is intended to overcome the difficulties which are experienced inthe mode of applying or aftixing a spring-tooth to a rakehead, which is described and claimed in Letters Patent granted by the Commissioner of Patents of the United States of America on the 14th day of Marchl846, to Seneca Ladd A serious difiicuity attending the operations of a rake having its teeth constructed and applied to the beam or rake-head according to the mode patented by the said Ladd, which difficulty must be obvious to every person who has had occasion to use such a rake, consists in the liability of the hay to catch and accumulate between the tooth and the staple and on the spring, and often to such extent as to prevent the return of the spring against the staple. The tooth is also subjected to a constant lateral looseness or/shake, and receives its lateral support mainly from the bearing of the spring against the side or sidesof the staple. The manner in which the spring is placed causes it to be so exposed that hay, brush, or other matters are liable to get caught between it and the rake-head, and thereby obstruct its operation.
In myimproved mode of applying the springtooth to the rakehead I make use of a box or socket, A, which is made and screwed down upon the top surface of the rake-head B, as represented in the drawings. l The said box or sockethasoneend-viz.,itsrearend-open,and receives through the open end. the upper end of the bent tooth C, through which and the two by a pin, e, which passes through the side of the socket. The socket or chamber whichcontains the tooth is made of a width just sufficient to admit of a free and uninterrupted play or movement of the tooth in a vertical plane. It therefore sustains the tooth in lateral directions and prevents any of the looseness or shake above alluded to. Besides this, the socket so covers the spring and is so placedviz., on the top of the rake-head-as to render it very difficult, if not impossible, for hay to obstruct the correct operations of the tooth or spring.
I lay no claim to the mode of applying each of the teeth to the beam or head of a rakeviz., by thejoint,spring, and staplein combination with each other and acting together, as speciied in the patent of Seneca Ladd; but
What I do claim as my invention is- My improved mode of applying each tooth to the rake-head-that is, the combination of the spring-socket, spring, and tooth, as arranged, constructed, and applied together and to the rake-head, substantially as specified.
In testimony whereof I have hereto set my signature this lSth dayofDecember, A. D. 1848.
LYMAN BAKER.
