' japplicationwfiled January Ofthe various: devices-[for clearing snow falls by hand :the so-called'scoop has eometo be one of the most popular by reason of :its efficiency and its availability.

The: greatestwdifliculty withthe jscoop :has been its inability ito withstand .overstraimor, in other words, gltS general Y design. was .such that over-zeal-on the part ofithewworkerior unusually adverse 1 conditions in the snow to be cleared was apt tobreakor overstrain the device. W

As a hand implement, its range of weight is'limited so that increasedstrength can not be attained by-mere structural augmentation. 'To efiect the necessary increase in strength, Without increase in-Weight or cumbersomeness, we have devised-our presentinvention. The scoop "shown in i the accompanying drawings is a commercial embodiment ofthe 'principles involved. iiiloiizthe characters indicating the sever-ah vparts in the drawings reference is made inthe accompanying specification. In the drawings:

Fig. 1 is a rear perspective view of such a scoop.

Fig. 2 a front View of same, and

Fig. 3 a longitudinal section onthe line 3-3 of Fig. 1.

The upwardly rising or angularly disposed handle of the scoop is the factor of its However,

destruction in the ordinary course of use.

7e, therefore, consider and treat our handle as a part necessarily in bent lever relation to the runners 2. This will be discussed more in detail, but it will be understood that infthe presence of crust or of heavy or compacted snow, deliberate or accidental increase of leverage creates a very severe strain at the apex of the angle (which generally is the fulcrum) of the leverage'as a whole.

Considering now the runners 2, we provide these with angular ends 2 and forward prows 2 At the prow ends we inset a cross bar 3 which extends transversely the full width of the scoop. The top of the cross bar .3 lies flush with the top of the runners 2 to permit the bottom boards 4 to be laid close and drawn tight so as to avoid play while securing themaximum bracing effect. The lateral bottom boards 4 are extended beyond "snow soo'or 'on s eet;

'the rear or beveled ends 2 of the irunnersto ifDL'Ij'i side supports .for thehandles 1.

The handles 1 are conveniently tapered at hei1-uuppeivend and. receive a ro s. bee v bolted thereon. At their lower ends ithe handles increase-(in tliickness as} at 1, and .meet at their bottom ends, with the ';incli, ;d ends 2 of the runncrs2 so thatthey in ,faot project under. the rear JQ lld ofthe runners. These angles ofthebent levers formfidiiby the. runner and handles are reiri;fprc ed by the upturned rear ends of the; runn er shoes .6, which are bolted through. the widened 1 p0r- .yti011S1 of the handles. 'The lower endsof the handles 1 are .roundeddn /a continuous curate from the undercut lowen edges of the runners 211p to the straight.Widenedbearing 1 of the baclrof; theghandle. .,-This giyesan -externally,reinforced angle between rnnner tilted position. It also aids in shaking back trimmings for a full load when clearing up.

Thus we see the runner and handles interlocked and externally braced and shod as well as laterally supported by the' rear ends of the boards 4:

We may next consider the scoop back 7 which extends down to and in bearing upon the upper rear ends of the runners. This affords the first cross lock for the inside angle of the leverage.

7 Next the central floor boards 4 are extended rearwardly across the lower edge of the back 7 and form an intermediate handle spacing brace opposed to and in the plane of the extended ends of the outer boards 4 The sides 8 extend from the rear ends of their lateral bottom boards 4 to the forward tip of the scoop where they have a forward taper forming an inclined edge which is also outwardly beveled. These form side cutting edges which are shod with a strip of steel 8 folded and bent to protect the'edge of the bevel and thecorner of the scoop, the bevel being filled at its juncture with the scoop bottom by a portion of the boards 4 or otherwise.

The forward ends of the runner shoes 6 are covered up and protected by a transverse metal point 9 folded over and riveted at 9 to the front edge of the flooring 4 and affording with the metal shod beveled edges 8 a continuous cutting front to the scoop. Two of the rivets 9 pass through the runner and shoe ends. The top and bottom folds of the metallic sheathing 9 are of the same width and the rivets 9 pass through both folds, as well as the included wood between saidfolds. This construction affords ample engaging surface for the rivets. The heads of the rivets are lodged in the upper fold of the metal and thus have good anchorage.

The scoop may be operated as any-ordinary scoop is now used, except that it may be worked harder and with greater efficiency and'can be used to cut and break blocks or crust and can be readily reversed-tofpull out a load. i

The structural embodiments, details and combinations may be variously used and re cast in variants of the form shown. 1 WVhat we therefore claimand desire to'se cure by Letters Patent is: g 1 y 1. In a snow scoop, a floor,a pair ofrunnersbeneath said floor and extending longitudinally the entire length thereof, the front ends of said runners being formed as prows and merging with said floor, metalshoes on said runners, a folded metal strip covering the bottom edge of said floor and the ends of said prows and shoes, and means set through said floor, said shoes, and said prows to hold the same in rigid relation to eachother. r r i I 2. In a snow scoop comprising bottom and side walls, the forward ends" of said walls being beveled, sheet metal guards on the edges of said walls, a pair of runners, the front endsof said runners being formed as prows and merging with said bottom, a

metal reinforcement covering the lower edge of said bottom and the included material of said runners, said reinforcement on said bottom adjoining said metal guards on the edges of said side walls to present a conguards in rigid relation to the entire length of said bottom, a pairof handles contacting the upper ends ofsaid runners, runner shoes extending about said runners and handle juncture and fastened to said handle thereabout, the opposite end of said runners and shoes being extended as a prow and merging with said bottom, and a folded sheet metalstrip covering the lower edge of said bottom'and said-merging runners',-, and, means passing therethrough w.

hold said bottom and said relation to each other. g

In testimony whereof We affix our signatures. e 7 GEORGE L. CROSMAN.
