LAND EULVERIZER.

To all whom it may concern Berea, county of Cuyahoga, and

' provement in .to distinguish inafter fully described and E. KARL, a resident of State of Ohio, have invented a new and useful Im- Land-Pulverizers, of which the following is a specification, theprinciple of the invention being herein explained, and the best mode in which I have contemplated applying that principle, so as it from other inventions. My invention relates to soil pulverizers and particularly to verizers which relates to the connection between the frame of the pulverizer and the seat-support.

The object such a connection which will be economical of manufacture and efficient in its operation. The'said invention consists of means hereparticularly. set

The annexed drawing and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be applied.

In said annexed drawing :-Figure 1 rep- 7 resents a fragmentary plan of a land-pulverizer to which my inyention has been applied. Fig. 2 represents a fragmentary front elevation taken upon by line III-III in resents a side the plane indicated by line,II-II in Fig. 1. Fig. 3 represents aside-elevation of the parts shown in Fig. 2 and taken upon the plane indicated said figure. Fig. l repelevation of a complete pulverizer embodying my invention, the tongue, however, being shown broken away.

The general type of pulverizer which is illustrated by the drawing and to which I have shown my invention to be applied, is that shown, described and claimed in Patent No. 1,023,139, issued April 16, 1912 The general structure therefore need not be specifically described, and the following description will be directed solely to that part of the device which embodies my invention. It will be noted that in the above-named patentedstructure, the spring seat-support has its lower end rigidly secured to the cross-bar 24: and that this cross-bar 1s rig- Specification of Letters Patent.

proved device, however, I provide the upper portion of each side-frame with a journal bearlng 39, preferably conical in form. In

each of these hearings is mounted a conwhich forms an integral part of a connecting member ll. This connecting member is formed with acentral conical bore 42 through which passes a bolt 43 whose outer threaded end is provided with two nuts 4A which in conjunction with awasher 45 hold the parts in place. The said journal is made slightly longer than the bearing so that the washer -15 when held tightly in place by thenuts, will not engage the opposing-face of'the side-frame 23,-but

thereby preventing binding, as will be readily understood.

The upper portion of each connecting member 41 is formed with an angle bar seat.

46 and in these seats are respectively secured, by' means of the bolts 25, the ends of the cross-bar 24 of the frame. To the cenleg of the angle bar 23 is rigidly secured, by means of the bolt 47, the lower end of the flexible and rearwardly-curved spring seat-support 38. Having its rear end suitably secured to the upper portion of the spring seat support is a chain 48 whose forward end is suitably secured to the frame of the machine. In the drawing I have shown this forward end secured to the tongue, which for the purposes of this application may be considered a part of the frame.

From the above-described construction it will be seen that while the lower end of the spring seat-support is rigidly connected with the cross-bar 23, said lower end nevertheless, has an independent axis of oscillation onthe frame of the machine, such axis being the axis of oscillation of the journals 39 of the connecting members 41. It will also be seen that the rearward movement of the spring seat-support is limited absolutely by the chain 48 which though collapsi'ble and offering no resistance to the forward movement of said support is inextensible when it is taut, and hence provides the limitation referred to. The oscillation, however, of the connecting members 41 is still further limited, and such limitation is provided, as shown in Figs. 2 and 3, by a:

flanged portion 49'which extends inwardly from each side frame 23, its upper end lying in the path of oscillatory movement of a projecting portion 50, formedon the said member 41. These means limit the one oscillatory stroke, the other oscillatory stroke being limited by a downwardprojection 51 Whosepath of oscillatory movement is intercepted by the inner surface 52 -of-said flange portion. The length of the chain 48, however, is such that during. the normal operation of the pulverizer, it will constitute the means for limiting the rear ward movement of the spring seat-support so that ordinarily the upper end of the'sai flanged portion will not be used for such also an'independent axis of oscillation; and

a collapsible member inextensible when taut, having its ends respectively secured to said frame and seat-support.

3. In a land-pulverizer, the combination of frame including side-frame members and across-bar connecting same; said crossbar being oscillatorily mounted on said sideframe members; a spring seat-support havingits,- lower end rigidly secured to said crossbar; and a member having its ends respectively secured to said frame and seatsupport.

In a land-pulverizer, the combination of a frame including side-frame members and a cross-bar connecting same; said crossbar and side-frame members respectively being provided with cooperating journals and bearings; a spring seat-support having its lower ends rigidly secured to said crossbar; and'a member having its ends respectively secured to said frame and seat-support.

5. In a land-pulverizer, the combination of a frame including side-frame. members each provided with an upwardly projecting portion formed with a bearing; a cross-bar having each end provided with a journal mounted. in one of said bearings, said bearings-being arranged so that said journals will have a limited oscillation therefor; a spring seat-support having its lower end rigidly secured to said cross-bar; and a chain connecting said seat-support and said frame.

6. In a land-pulverizer, the combination of a frame including two side-frame members each provided with a bearing; two

members each formed with ajournal respectively mounted and secured in said bearings; a cross-bar rigidly secured to said journal members; a spring seat-support having its lower end rigidly secured to said crossbar; and a chain having its ends respectively secured to said frame and said seat-support.

Signed by me, this 19th day of January, 1915.
