AMIL MOCKEL, OF WILLISTON, NORTH DAKOTA.

DIRT-SHIELD FOR PICKS.

To all whom t may concern.' Be it known that I, AMIL Moonen, a .citizen of the United States, residing at Willis* ton, in the county of Williams, State of North Dakota, have invented a new and useful Dirt-Shield for Picks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a dirt shield for picks, and has for its object-to provide a device of this character which embodies novel features of construction whereby it can be readily applied to the handle of a pick or like tool and will prevent hard particles from flying into the face and also prevent mud from being spattered upon the clothes.

Further objects of the invention are to provide an adjustable shield for picks which is comparatively simple and inexpensive in its construction, which can be readily applied to a pick or removed therefrom, which can be adjusted to fit different sizes of picks, and which will enable the pick to be used upon hard surfaces such as paved streets without the danger and discomfort which is occasioned by the flying of solid particles into the face.

"With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in whic Figure 1 is a side elevation of a conventional pick showing a dirt shield constructed in accordance with the invention applied thereto.

Fig. 2 is an end elevation of the pick taken on the line 2 2 of Fig. l.

Fig. 3 is an enlarged side elevation of the dirt shield, the pick handle being shown in section.

Fig. 4 is an enlarged transverse vertical sectional view through the dirt shield.

Fig. 5 is a horizontal sectional view through the same taken on the line 5--5 of Fig. 3.

Corresponding and like parts are referred to in the following description and indi- Speccaton of Letters Patent. Patented Allg. 14,1917. Application filed May 31, 1917.

cated in all the views of the drawings by the same reference characters.

Referring to the drawings, the numeral l designates a handle of an ordinary pick 2 of the type which is commonly used for digging upon the streets. The shield includes a split sleeve 3 of sheet metal or like material, said sleeve carrying a guard plate 4 which is rigidly secured thereto and normally projects downwardly therefrom. The edges of the split sleeve 3 overlap each other at the top of the handle 1, and may be slotted to receive a tubular bolt 5. .A nut 6 is threaded upon the tubular bolt and it will be obvious that the size of the sleeve 3 can be adjusted to t any particular handle by causing the edges thereof to overlap more or less, and the sleeve then locked in an adjusted position by tightening the nut 6. A set screw 7 is threaded within the tubular bolt 5 and provides a means for locking the sleeve 3 in an adjusted position upon the handle l.

The guard plate 4 projects downwardly from the sleeve 3, and is shown as having an extension S adjustably fitted upon the lower end thereof, thereby enabling the guard plate to be lengthened or shortened, as may be found necessary to obtain the best results. The sides of the extension 8 may be returned around the edges of the guard plate 4, as indicated at 8a, and suitable fastening means such as the screws 9 may be provided for locking the extension in an adjusted position.

When the pick is being used in soft earth the dirt shield can be completely removed therefrom, since under such conditions it would not be desirable to have the shield upon the pick. However, when the pick is to be used for digging in hard material,

'as upon a paved street, the sleeve 3 is slipped over the pick handle 1, having been previously expanded or contracted to fit the pick handle with a fair degree of accuracy. i4fter the sleeve has been properly positioned upon the pick handle the set screw 7 is tightened, thereby locking it securely in the desired position. The extension 8 can then be moved in or out to vary the effective size of the guard plate, and when the pick is used the flying particles of stone and mud which would otherwise strike against the person of the user will be intercepted by the guard plate.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is

l. In combination with a piek, a split sleeve adapted to be iitted upon the piek handle, means for adjustably connecting the Aedges of the split sleeve for varying the siZe thereof, means for looking the sleeve in an adjusted position upon the piek handle, and a transverse guard plate rigid with the sleeve and projecting downwardly therefrom.

2. In combination with a pick, a split sleeve adapted to be litted upon the piek handle and formed with slotted overlapping edges, -a tubular bolt adjustably connecting ltheslotted overlapping edges, a clamping ,nut threaded upon the tubular bolt, a set vscrew ,j extending through the tubular bolt 'for engagementwith the handle to look the sleeve .in an adjusted position thereon, and a transversely disposed guard plate rigid -with thesleeve and projecting downwardly therefrom.

3. In -eomblnation with a piek, a guard plate disposed transversely with respect to Vthe piek handle and projecting downwardly `with the sleeve and projecting downwardly therefrom, an extension adj ustably mounted upon the bottom of the guard plate, and inea-ns for looking the extension in an adj usted position.

ln testimony whereof l have signed my name to this speeilication in the presence or 40 two subscribing witnesses.
