RAKE.

Application led October 18, 1924. Serial No. 744,412.

To all whom t may concern.'

Be it known that I, TILL-IAM SCHRonR, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvements in Rakes, of which the following is a specification.

This invention relates broadly to an improved rake, and it has specific reference to several improved structural features. The first feature is the peculiar construction of the head, wherein the same is well adapted to accommodate the teeth, the same being formed with a groove, in which the heads on the upper ends of the teeth are received, a rod being placed in the groove and retained in place, to at all timesmaintain the point of the teeth in a plane with each other.

Another feature is the specific construction of certain of the teeth, wherein they are provided on their lower ends with means for facilitating the dragging of the rake over rough surfaces.

A third, but no less important feature, is the construction of the handle, and the means for attaching it to the head when the handle is permitted to be folded alongside of the head, to render the rake easily compact for shipping, etc.

Other features and advantages of the invention will become apparent from the following description and the drawing.

In the accompanying drawing, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a top plan view of a rake, constructed in accordance with the present invention.

Figure 2 is a detail view of the central portion of the rake, showing the construction of the handle and its connecting means.

Figure 3 is an enlarged sectional view, taken on the plane of the line 3--3 of Figure 1.

Figure 4 is a similar line 4 4 of Figure 1.

Figure 5 is a detail perspective view of one of the rake teeth.

Referring to the drawings in detail, wherein the reference character 1 designates the cylindrical head, in the present instance the said head `is provided along its top and from end to end with a longitudinal groove. Ex-

view, taken on the prevent rotation of the teeth.

Vtending downwardly from this groove and to the bottom side of the head, are vertical longitudinally spaced bores through which the rod like teeth 2 extend. As seen more clearly in Figure 5, the tooth is provided, at its top with a polygonal elongated head 3, which is seated in the aforesaid groove, to Fitted intothe groove is a longitudinal retaining rod 4, which is held in place by appropriate clamps 5. At each end, and in the middle, I provide special rack teeth of the construction shown in Figure 4. Referring to this ligure, it will be seen that the tooth is provided with screw threads, at its lower end, and a spherical ball or knob 6 is screwed thereon. Obviously these balls constitute shoes, which serve to permit the rake to ride easily, upon irregular surfaces.

Observing now, the foldable handle, it is to be seen that the same is designated by the reference character 7. It is provided, on its inner end, with a ferrule 8 and a flat extension plate 9 is bolted, or otherwise secured thereto, the plate extending considerably beyond the free end of the ferrule and heilig provided at one edge with a notch 10, and at its free end with an opening for passage of a pivot pin 11. For the purpose of connecting this handle with the rake head, I. provide a special two part clamp 12, comprising a pair of plates 13 of duplicate formation. Each plate is provided with a channel, and when the channel shaped portions are brought together, they form a. clamp for connection of the plate with the head 1. In the arrangement shown, four bolts 14 are utilized for maintaining the plates in place. A spacer and tie 15 is connected with the inner pair of bolts, for retaining the plates in spaced relation. The plates are formed with aligned arcuate slots 16 and the extension 9 carries a bolt 17, which extends through the slot. The bolt, in turn, is provided with a thumb nut, and it is obvious that with this arrangement the handle may be moved to any desired angle with respect to the head, and retained in that position. Also, it may be folded alongside of the head, and retained in that position to render the rake compact for shipping, storage, etc. l/Vhen it is swung to the last named position, the aforesaid notch 10 cooperates with the spacer 15, at one of the bolts 111-, to permit the handle to lie in Close spaced relation with respect to the rake head.

I claim:

A rake comprising a head provided with a longitudinal slot, and a plurality of longitudinally spaced vertical bores extending downwardly from said slot, teeth extending through Said bores, said teeth having heads on their upper ends fitted into said slots to 10 prevent the rotation thereof7 a retaining rod seated in said slot and engaging said head to maintain the teeth in horizontal alignment, and clamps for securing said rod in place.

In testimony whereof I affix my signature.

WILLIAM SCI-IROER.
