' i Patented oci. 21, 1930 This invention relatesfbroadly i to portable a Y band-operated implements; andv more specifically to apparatus oiV thefty'pe adapted 'forvuse 'in the .removahofr v.snow'or 'other rela- 5 tively light, loose comminuted2mater1al One of' the objects of `this inventionV isv to 'f construct an implementwhich may be pushed orfshoved overuneven, irregular surfaces, suchfas the jfurrow'ed Vpath oifa driveway Aor 10 the undulated surface oifa sidewalk which is formed offl broken iiagstones'or slag. i

' Another object of this inventionis to provide an 1 i whichmay be expeditiously operated'under variable conditions and'ivvhich lfurthermoreA will eliminate thearduous labor of lifting,-

vand throwing the materiales is necessitated '25 scoop.

Another ob struct a light, portable appliance, durable of y construction and economic of manufacture.

Other objects more or less ancillary of the foregoing and the manner in which all the various objects are realized will appear in j the following description which, lconsidered in connection withy the accompanying drawthe invention. p

In the drawings Y c Fig. 1 is a view infperspfective illustrating Y the general construction of the preferred embodimentof the invention; y y Fig. 2 is a detail viewin section, shown upon anenlarged scale,the section being taken on a plane indicated by the `line 2-#2 in Figl; Y v v' Figs. 3, 4 and are -fragmentary,s ectional views, similar to a port-ion of the detail shown in Fig. 2 and illustrative of alternate methods vof securement of the snow plow share with the frame. i y f ,t t

arcuated terminating end sections 14C. *These .v i

endsections are bowed or' bent upwardly,'di, vergent to the plane common to the side A'rails v through an arc ofs'ubst-anti'ally 90".y y -The plate 11,'ssupported upon the linear port-ions of the frame 10-andfispreferably r longitudinally 'adjustable therewith. l In the instant case-the lateral edges ofthe plate are foldedoverqthe side;y rails 13 and are-fric'- tionally engaged thereby through their lformed slightly diver ent,-with respect to its herent resiliency of the frame which may! be i f j transverse sectional view -taken Referring tothe constructionillu'strated kin l f andlovoped end ofthe frame, and are'extended i i `major-xaxis, in its unstressed` form.V The K upperedge ofthe-plateor plow-sharellis provided with a handlef'for" the convenience l of theA operator iin raising or lowering'fthe share. This handle be oi'- any 'suitable construction such as the aperture 15 r.herein illust-rated"fy E `f` In'Figure 3 analternate-lock is illustrated which comprises a 'dowel f pini 19 vsuitably at- L itachedtoV the louter Wall? of the iframe and positioned :for reentrant engagement with one *of a series Ofa'pertures 20'in thelfolded edge ,i

Airictiona'lclamping mechanism isillus- `ltrated in Fig. 4, this embodimenty contemplat- Aing the securen'ient of the plateupon .the 'iframe 'by thefdistortive'influence ofa clamp!A ing nut`v 21retained upona bolt 21%which passes through' aligned holes 22ldrilledin thel f' Another-alternativeclamping mechanism is shown in Fig. 5 wherein the plate l1 is provided with bolts 24, cooperatively associated with angle clamps 25 and nuts 26, which are capable of adjustment to effect the retention of the plate upon the frame side rails 13.

The plate or plow-share l1 may be constructed in various forms to accommodate its use with the variable adaptationsto which the implement is susceptible. In Figures 6 and 7 an angulated plate 27 is shown which is particularly adapted to deflect fthe Vsnow to the sides of the pathway rather than to accumulate the same upon the face of the plate. The configuration of the plow-share in this caseis preferably formed so that vthe lower edge 28 may be parallel with the plane of the surface over which it is translated under normal Working conditions and adapted to engage the surface of the ground over which it is traversed.

In the operation of this implementthe plow-share is first vertically adjusted upon `the frame to cut a furrow or path `throughthe `drifted areas or to remove a limited portion of the upper surface of a heavy, evenly distributed snow fall. As tliefcoating-of snow upon the path is cut away the share may be vadjusted into intimate association with ythe floor of the path, obviously this adjustment being concurrent with the irregularities of the surface of the path orfdriveway.

Utilizing tl e looped portions 12 of the frame as a handle vthe operator may push vthe implement before him, adapting the upturned arcuated end sections of the plow frame as runners which will cut their way through the snow 'and glide over irregularities in the ground. The loaded plate may be dumped by divertingthe plow from the course of the pathway and then tilting it forward or, in the form having the plate .retained by the resilient frame, by drawing the plate upwardly upon the frame so as to effect the discharge of the load by gravity.

Although the foregoing description is necessarily of a detailed character, in order that the invention may be completely set forth, it is to be understood that the specific terminology is not intended to be restrictive or confining, and that various rearrangements of parts and modifications of structural detail, such as the substitution of heterogeneous side rails for the looped frame member or the transposition of the plate upon the frame, may be resorted to withoutdeparting from the scope or spirit of the invention as herein claimed.

What I claim is:

1. An implementcomprising a looped frame having substantially arcuated free ends, a plate slidably `engaged upon linear portions of the said frame and means for retaining the vplate upon the frame.

2. A snow plow embodying a frame member and a plow-share, the said framemember 'foldedmargi'nal edges supported thereon by the engagement of said folded marginal edges vwith said linear portions of the frame.

5. A portable implement for removing snow'comprisingaframe formed from a continuousv strip of tubing, the said strip -bei-ng formed in an openv loop with upturned yterminating ends, a plate supported upon the said frame above its upturned portions, and adjustabl-y secured thereon.

6. A portable snow plow comprising a. pair of substantially parallel frame side members having arcuated terminating ends, a plate having its lateral edges conformable with the contour of the said side members, and en veloping at least 180D of thepperiphery of each side member.

7. An implement for the removal of snow comprising spaced frame members, having areuated free ends, aiplate supported thereby, and means for adjusting thesaid plate longitudinally with respect to the arcuated yfree ends of the said frame members.

8. An implement embodying a frame formed from a. continuous strip of metal, a plate mounted thereon and longitudinally adjustable thereon, and runners 'formed at the lower end of saidframe.

In testimony whereof I hereunto afx my signature tliis 17th day of May, 1928.
