' COAL-SHOVEL.

SPECIFICATION forming part of Letters Patent No. 543,710, dated J' uly 30, 1895. Appiication inea November 1.1894. serai 110,527,616. me modera Zo all u hom, t may concern.-

Be it known that I, MARTIN L. TATE, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improve- 5 ment in Coal-Shovels, of which the following is a specification.

My invention has reference to coal-shovels; and it consists of certain improvements, which are fully set forth in the following specifica- Io tion and shownin the accompanying drawings,

which 'form a part thereof.

This application comprehends certain improvements in coal-shovels, wherein the shovel may be adapted to lift coal or to sift 15 ashes to separate the unburned coal from the dust and cinder.

In carrying out my invention I provide a shovel-blade with apertures upon the floor, and if desired upon the sides.' To such shovelzo blade I apply an adjustable slide or movable blade, which is adapted to lit upon the floor and sides of the shovel-blade and be moved longitudinally thereupon. This slide is also provided with apertures corresponding to the 2 5 apertures in the oor and sides, and so -that when moved :it may open or close the said apertures of the shovel-blade, as well as the apertures formed in itself. A suitable toggle connection may be employed for the purpose 3o of adjusting the movable blade, so as to put the shovel into condition to be used either as a liftingor as a sifting shovel.

In the drawings, Figure 1 is a perspective view of myimproved shovel. Fig. 2 is aplan 3 5 View of same. Fig. 3 is a cross-section of same on linea; x. Fig. 4t is a perspective view of the end ofv the movable blade, and Fig. 5 is a sectional elevation on line Y Y of Fig. 2. Fig. 6 is a view of the toggle-lever.

A is the blade of the shovel proper and is preferably stamped from a single piece of metal and formed with a handle. The for' ward part of the lioor and sides of the blade are perforated, as at B, and the upper edges of 4 5 the sides C turn over and form guide-grooves,

as at D. Fitting to the interior surface of the iioor and sides is the plate E, which is provided with sides F, made to conform to the sides C and adapted to fit into the guidegrooves D thereof, as clearly shown in Fig. 3. 5o The plate E is provided with apertures Gin its door and sides to correspond to the apertures in the Iioor and sides of the blade of the shovel proper.

The extreme forward edge of the plate E is 55 slightly enlarged, as at e, to form a shoulder, to make the outer surface of said plate correspond 'in alignment with the outer surface of the shovel-blade, and thereby protect the juncture of the two blades and prevent ob- 6o structions passing therein. The forward part of the plate E is also provided with upright shoulders K, which fit against the forward edges of the guide-grooves D and limit the backward movement of said plates E. The 65 plate is moved forward and held in Suchforward position by the toggle-levers H, which are pivoted together at h and provided with a small handle by which said toggle is moved. One end of the toggle-lever is hinged to the 7o plate A and the other end to the plate E. The toggle-lever is provided with a stop J to limit its motion when the plate E is fully thrown forward, and at the same time to lock the side plate against backward movement.

It will be seen that when the movable blade is extended the capacity of the shovel is greatly increased, and this is independent of Whether the apertures are used or not.

It is evident that the shovel, as indicated in 8o Fig. 2, is in condition to be used as a useful coal-shovel, and in the condition shown in Fig.

l it is adapted to be used as a sifting-shovel, these two figures showing the extreme adjustment of the movable portion. 85

While I prefer the construction shown, it is evident that the details thereof may be modied in various ways without departing from my invention.

Having now described my invention, what 9o I claim as new, and desire to secure by Letters Patent, is

l. A combined coal and sifting shovel consisting of the main blade having a handle and provided with apertures, in combination with 9 5 a movable blade fitting within the main blade and also provided with apertures and having its end projecting beyond the main blade,

and means for adj Listing and locking the inovable blade upon the main shovel blade to open or close the apertures.

2. In a combined coal aud sifting shovel, the combination of the main blade provided with apertures and a handle, with a perforated movable blade movable relatively1 to tlie'liandle and main blade, and a pivoted locking device arranged Within the main blade at the rear for lockingr the movable blade in its adjusted position against backward movement.

3. In a shovel the combinationof the main blade having its door perforated and its sides bent over to form guide grooves, in combination with a movableblade fitting upon the said shovel blade and having its sides guided in the grooves and also provided with apertures, and means to adjust the movable blade upon the shovel blade so as to open or close the said apertures.

4. The combination of tbe main shovel blade A having apertures B, the movable blade E having apertures G and adjustably supported upon the said blade A, and a toggle connection H for adjusting the blade E upon the blade A.

5. A combined coal and sifting shovel com sisting of a main blade made box shaped and having its sides and bottom provided with apertures and its rear with a handle, in coinbination with a movable blade havine,r bottom and sidesiitted within ille main blade and also having apertures in its bottom and sides and having its forward end projecting1r be vond the main blade, stops to limit the backward movement of the movable blade upon the lnain blade When the apertures are closed, and a lock to lock the movable blade against backward movement when the apertures are open.

In testimony of which invention I have hereunto set my hand. i
