JAMES MACPHAIL, OF DAVENPORT, IOWA, ASSIGNOR TO DAIN MANUFACTURING l COMPANY OF IOWA, OF OT'IUMWA, IOWA, A CORPORATION OF IOWA.

TOOTH-HOLDER FOR SULKY HAY-RAKES.

Specification of Letters Patent.

Patented June 2, 1914.

Application filed July 9, 1913. Serial No. 778,017.

To all whom it may concern Be it known that I, JAMES MACPI-IAIL, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Tooth-Holders for Sulky Hay-Rakes, of which the following is a specification, reference being bad to the accompanying. drawings.

This invention relates to improvements in the means for holding in place on a rake the heavy wire teeth of the rake.

It has for its objects to so form or shape the holder that it can be pressed from a single sheet of steel and will be light in weight and very strong; that will securely hold the teeth in place without liability of side play and yet will so hold the lateral or turned upper end of each tooth bar as to permit the desired flexing or oscillating of the tooth in its openingsin the holder and at the same time provide an extended and rigid bearing for such turned end. I accomplish these objects by the construction shown in the drawings and hereinafter particularly described.

That which I believe to be new will be set forth in the claims.

In the drawings, Figure 1 is a face View of one of the improved holders applied in position on a rake, and showing also the upper parts of a number of rake teeth held by said holder; Fig. 2 is an enlarged vertical section through the parts shown in Fig. 1; Figs. 3 and 4; are views similar to Figs. 1 and 2, respectively, but showing a modification in the form of the holder; Fig.5 is a perspective view of the holder of Fig.1, looking toward the under face thereof; and Fig. 6 is a similar View of the form of holder shown in Fig. 2.

In the several figures in which. corresponding parts are indicated by like reference characters, 10 indicates a rake head extending from side to side of a sulky hayrake, and, as shown, formed of a piece of angle-iron.

11 indicates a number of rake-teeth of heavy spring wire which are held in place on the head 10 by my improved holding means. Each tooth is turned at right angles to form what is known in the trade as a lateral, such portion being here indicated by 12.

The parts so far named are common to Figs. 1 and 4., but referring now particularly to Figs. 1, 2 and 4:, the tooth-holder as a whole is indicated by 13. It is best formed of a pressed steel plate as thereby the maximum strength combined with the minimum of weight is secured. The holder at its lower portion is made channel-shaped, the lower flange of such channel portion being indicated by 14, the back thereof by 15, and the upper flange by 16. The lower flange, in the construction shown, is substantially horizontal while the upper one is slightly inclined upward. 17 indicates an extension of the upper flange, which extension, as shown, is formed by bending the sheet of material backward and then upward, such bending being such as to produce substantially an ogee curve. Such extension 17 provides, as will hereinafter appear, asuitable support for the turned ends or laterals of the rake-teeth to rest upon, and, in connection with the two walls of the angleiron 10, forms a housing or inclosure for such laterals. 18 indicates a series of notches in the lower flange 14:, and 19 indicates a series of holes each formed in the parts 16 and 17, the holes 19 being alined with the notches 18. 20 indicates bolt holes through the wall 15 of the channel through which pass bolts 21 for securing the holders to the angle-iron head 10.

For convenience in connecting and disconnecting the teeth the holder is made up of several sections or pieces placed end to end, and one only of such sections or pieces 13 is shown. Each of such sections is adapted to secure in place a plurality of teeth and as such number of teeth varies according to the wishes or ideas of different users each section is preferably constructed with more notches 18 and holes 19 than are in use for teeth at any one time, and thereby by a proper selection of such notches and holes the user of the rake can space the teeth at the desired distance apart. To put into use the holder, formed of a plurality of the sections 13 placed end to end, the teeth are placed so that they extend through the desired alined notches 18 and holes 19 and have their turned upper ends or laterals resting upon the curved upper surface of the extension 17. The holder is then placed against the inner face of the vertical. wall of the angle-iron head 10 and bolted in place by the bolts 21. \Vhen thus in place it will be seen that the curved member 17 and the two walls of the angle-iron head 10 constitute the walls of a chamber in which'snugly fit the laterals 12 of the several raketeeth, the said lateralsibeing, thus prevented from rattling or wabbling, but being free'to have a slight turning or hinge-like movement when the teeth springas the result of meeting with an obstruction. Such movement of the teeth due to their being compelled to yield from time to time on account of meeting obstructions is not interfered with by the holder, but such necessary movement is permitted by the character of the pairof openings in the holder through which each tooth passes, such openings, while acting to prevent any material side movement'of thetooth not acting to prevent .the slight amount of movement caused by thespringing of the tooth'when it meets an obstruction. Each hole 19 being formed through the members16 and 17 and such parts standing. at an angle. to each other such holes constitute in effect merely retaining notchesas are the. notches 18'l0cated below them, but by reason of the holes being. formed through both members 16 and 17 the notches thus formed present double the amount of side bearing for-the" teeth than '30 do the notches 18. With-three bearing points ateachside of each tooth and with the laterals at the upper ends inclosed as shown and described, it will be understood that the teeth will be maintained at all times in proper working position. The bending .of the metal sheet as shown to form the parts 16 and 17 is of very considerable advantage.

in another way also, for by so bending it and presenting thebend to and against the angle-iron 10 a very stiff construction of holder is provided whereby buckling or distortion of the holders is prevented in case the nuts on the securing bolts '21-are screwed up verytight. 7 7

Turning now to the modification in the construction of the holder shown in Figs. 3, 4 and 6,22 indicates the holder as a whole, which, as in the first-described construction I form from a single piece of metal. In this holder the back wall thereof is indicated by 23. and is provided with a flange 24 at its lower edge, in which edge is formed tooth-retaining notches 25. The upper portion of the wall 23. isqslit to per-V m t of the bending down of pieces that form brackets 26 that are substantially parallel withthe flange 24: and are adapted to support the rake-teeth laterals when the 'thelteeth in working position. 27 indicates bolt-holes for the passage of the retaining bolts 21 by which the device is fastened to that bears against a wall of; the angle-iron,"

the angle-iron head It). When so fastened in place it will be seen that the rake-teeth as in the first-described construction and the same slight hinge-like action permitted when the rake-teeth are sprung by meeting an obstruction. The formation of the separated and inturned brackets 26 produces in effect a holder of channel-like construction, of which such brackets constitute one of the flanges, so thatin this respect the two con' structions resemble each other, and they also are alike in that each provides, when attached in place to an angle-iron'head, as showman inclosed chamber above the channel portion, in which" chamber the rake-teeth laterals are housed and permitted to rock as required.

The combination with an 'angle-iron 'rakehead, of a tooth-holder secured to theinner face of one wall of'said angle-iron, said holder comprising a channel portion that bears against a wall of the angle-iron and having an extension that forms a wall of a housing adapted to receive a rake-tooth lateral the walls ofwsaid angle-iron constituting'a portion of said housing, 4 V
