J. FISHER COAL SHOVEL Filed July 13, 1953 Patented June 18, 1935 c y J n Y 1 v 2005,4, 16v` y' 3 n l 4: A ycoAL sovEL i John H. Fisher, Elyria, Ohio Application July 13, 1933, Serial No. 680,302 y 1 Claim.

'Ihis invention relates to coal shovels and has for its object the provision of a tool which may be easily handled and bythe use of which ashes may be separated from cinders and unburnt coal which may have collected in the ash pit of a furnace.

A further object of the invention is to provide a simple and inexpensive construction whereby the screen will be iirmly retained in the shovel or scoop While in use and may be easily detached when its removal is desired.

Other objects of the invention will appear incidentally in the course of the following description and the invention resides in certain novel features which will be particularly pointed out in the appended claim.

In the annexed drawing,

Figure 1 is a perspective view of 'a coal shovel embodying the present invention,

Figure 2 is a longitudinal section on a what larger scale,

Figure 3 is a detail perspective view showing the construction of the screen, and

Figure 4 is a detail view of the removable journal.

The body E of the shovel is in the form of a scoop having a bottom, back and sides and having an open top and front, as clearly shown in the drawing. This body may be easily constructed of sheet metal stamped into the desired form and having its side portions extended transversely and overlapped at their ends to form the'back member, as shown at 2. A short sleeve or socket 3 is also formed on the back member at the center thereof and the end of the handle is received in said socket and secured therein by rivets, as indicated at 5. Near their upper rear corners, the sides of the scoop are provided with SOmeopenings, indicated at 6, and from one of saidv openings rises a notch or open-ended slot 7, as shown. y f

The screen comprises a sheet of reticulated material, preferably woven wire, as shown at 8, and a reinforcing frame consisting of side and iront members 9 and a back member I0. This frame is formed of sheet metal, the side and front members being in the form of reentrant flanges, as shown clearly at Il in Figure 3 and the edges of the screen being folded inwardly on themselves and inserted between the members of the ange and then secured rigidly therein by crimping or compressing the membersof the ange. The back member I0 rises from the frame and has secured thereto by nails, rivets, or other suitable fastenings, a rod l2 which is of circular cross section through the greater portion of its length, one end being reduced and formed with ilat sides to produce a trunnion I3 which may pass through the slot or notch l to position the rod in the tion of the shovel while the cinders and unburntV coal will be retained upon the screen, as will be understood. If it seems necessary, the tool may be shaken slightly so that any ashes which do not pass at once through the screenwill be caused by the agitation tor separate from the cinders and coal and pass into the space below the screen. The coal and cinders may roll from the screen after they have been relieved of the n,

retarding influence of the ashes and the ashes maythen be dischargedat a suitable dumpingV place after the screen has been first turned upwardly and backwardly about the rod I2 as a center whereupon the free edge of the screen will rest upon the handle, as shown by full lines in Figure 2.

In applying the screen to the shovel, the axle or rod l2 is positioned with the flat sided trunnio-n or stern I3 alined with the notch or slot l' so that the rod maybe easily pushed to position within the shovel, after which a slight endwise movement will permit the round end of the rod to be engaged in the opening 6, provided therefor in the side of the shovel. The screen will then be swung down to the working position and this movement will cause the flat sided trunnion I3 to assume a position transverse to the' slot or notch l, as shown in Figures l and 4, so that the screen cannot beV accidentally released from the shovel. It will be understood, of course, that the flat sided trunnion i3 is somewhat longer than the thickness of the material of the shovel so that if the round portion ofthe rod l2, at the base of said flat sided trunnion, be disposed against the inner facev of the side of the scoop or shovel, the screen may be easily moved downwardly to its working position and will be secured in place by the slight endwise movement of the rod, which has been mentioned.

Fromthe foregoing description, taken in connection with the accompanying drawing, it will be seen that I have provided an exceedingly simple and inexpensive tool whereby the labor of sifting ashes will be expedited, and when desired the screen may be very easily removed from the shovel.

Having thus described the invention, I claim: A coal shovel comprising a scoop having pivot openings in its sides at the upper rear corners thereof and a slot rising from one of said openings through the upper edge cf the side of the scoop, a, handle secured on the back end of the scoop at thebottom thereof and extending upwardly and rearwardly therefrom, a screen, a

reenforcing frame secured around the edges of` the screen and having its rear end extended relatively upward for the full Width of the frame, and a straight pivot rod secured rigidly to the free edge of the extended rear end of the frame with its ends projecting beyond the sides of the frame, one end of said rod having flattened sides whereby it may pass through the slot in the edge of the scoop and rotatably seat in the opening below the slot and the opposite end of the rod being circular in cross section whereby it may rotatably seat in the opening in the adjacent side of the scoop upon endwise movement of the rod and screen after the fiat-sided end of the rod is seated.
