LEONARD \V. OBRIAN, OF BELLEVUE, OI'IIO, ASSSIGNOR TO THE FREMONT CULTIVATOR COMPANY, OF SAME PLACE.

CLIP OR SADDLE RAKE-TOOTH HOLDER.

SPECIFICATION forming part of Letters Patent No. 408,128, dated July 30, 1889.

Application filed June 15, 1888. Serial No. 277,223. (No model.)

To aZZ whom it may concern:

Be it known that I, LEONARD W. OBRIAN, a citizen of the United States, residing at lellevue, lluron county, State of Ohio, have invented a certain new and useful Improvement in (llip or Saddle Rake-Tooth Holders, of which the following is so full, clear, and exact a description as will enable others skilled in the art to which my invention ap- IO pertains to make and use the same, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of a part of a rake-head, showing my improved clip and a tooth secured thereto. Fig. 2 is a transverse vertical section of the head and clip in the plane as as, showing the position of the tooth within the two. Fig. 3 is a rear view of the clip, tooth, and rake-head.

This clip is especially designed for use in holding a steel tooth to the rake-head of a steel-tooth horse-rake.

The object of the invention is to provide a clip or tooth-holder which shall securely hold the tooth in place and at the same time by reason of the peculiar construction of the head and tooth leave the latter free to vibrate and oscillate to a limited extent as obstacles are encountered while the rake is being used.

0 In the accompanying drawings, A designates a clip made in accordance with my invention. The top of the clip is provided with a socket B. At a point nearly directly below the socket B and nearly in alignment therewith extend downward two projections or fingers b b, forming an inverted- U-shaped opening E, which,when the clip is in position on the rake-head, forms a guard and frictiou-bearing for the tooth along the rear of the perforation through the rake-head. In front of the socket B is a slot 0, extending from the socket 13 to the front side of the top of the clip A. From near the upper front end of the clip A extend downward a second pair of projections or fingers I) l), forming an inverted-U-shaped opening E, and are similar to those which extend down to the rear of the head of the rake. A bridge D strengthens the clip between the slot 0 and the U-shaped opening E, as is clearly shown in Fig. 1. The lower ends of the U-shaped openings E and E are left open at the bottom on both sides of the rake-head. A bolt F extends through the rake-head through a perforation G, and serves to hold the clip against lateral displace- 5 5 ment. The rake-tooth II is formed with an enlarged curved portion I near its upper end, while its extreme upper end is reversed and bent over nearly upon itself, forming a hook or fastening-point .I. The head Ii is trans- 6o versely perforated at L to receive the tooth H, and this perforation through the head is small and circular at its front and larger and elongated at the rear. This gives the tooth a certain amount of vertical and torsional 6 play through the perforation L in. the rakehead. As the rake tooth is put in position through the head, the bridge D will abut against the rake-tooth from above and help to hold it from vertical displacement. A portion M of the rake-head K above the perforation N at the front of the rake-head will also abut against the tooth from thetop and serve as an additional means of holding the tooth against accidental vertical displacement. From the nature of the case it will. appear at a glance that the tooth is held against vertical displacement by a port-ion M of the material of the rake-head. The upper. end or hook J of the rake-tooth will be securely held against movement in any direction by the socket l3 and the top of the rake-head K. The clip A will in turn be held against lateral displacement by the bolt F, and it will beheld against vertical displacement by frictional cont-act with the head of the rake against the fingers Z) Z) Z) I), as the latter are snugly bolted to the rakehead.

From the foregoing it will be seen at a glance that the upper end of the tooth will scribed, consisting of a clip provided with a socket and a slot at the top, and having fingers which extend below the plane of the top of the clip, forming U-shaped openings, in combination with a rake-head having a transverse perforation and a rake-tooth extending through said perforation in the rake-head and through the U-shaped openings in the clip, all constructed and combined to operate subtantially as and for the purposes specified.

2. A tooth-fastening of the character described, consisting of a clip provided with a socket and a slot at the top, and having fingers which extend below the plane of the top of the clip, forming invertcd-U-shaped openings open at the bottom, in combination with a rake-head having a transverse perforation small at the front and larger at the rear, and a rake-tooth extending through said perforation in the rake-head and the U-shaped slots and fitting within the socket at the top of the clip, all constructed and combined to operate substantially as described.

3. A tooth-fastening of the character described, consisting of a clip provided with a socket and a slotat the top, and having fingers which extend below the plane of the top of the clip, forming inverted-U-shaped openings, in combination with the rakehead having a transverse perforation small at the front and larger at the rear, and a rake-tooth extending through said perforation in the rake-head and fitting within the socket at the top of the clip and extending through the U-shaped openings in the clip and abutting against a portion of the rakehead above the small end of the perforation in the front of the rake-head, substantially as and for the purposes specified.

In testimony whereof I a-ffix my signature in the presence of two witnesses.

LEONARD XV. OBRIAN.
