2 Claims.

This invention appertains to tools, and more particularly to a novel attachment for carpenters planes.

One of the primary objects of my invention is the provision of a novel guard for planes for effectively protecting the sharpened edge of the knife or blade thereof against foreign objects when the plane is not in use.

Great care must be taken by the carpenter in placing planes away during their period of nonuse, or the blade will become dulled or chipped by contact with other objects, The planes should be laid on their sides, so that the knives or blades thereof will not rest upon hard objects, and when the planes are laid on their sides, the same take up too much room in a tool chest.

It is, therefore, another salient object of my invention to provide a guard which can. be easily slipped on and off the plane stock, and which '20 will completely house the sharpened end of the blade or knife of the plane, whereby said edge will be effectively protected, and whereby the plane can be placed in any desired position in a tool chest.

25 A further important object of my invention is the provision of a detachable guard for planes for completely enclosing the sharpened end of the knife or blade thereof, with the guard of such a, shape and character that the same will 30 be spaced from said sharpened edge, so that the guard itself will not injure said edge.

A still further object of my invention is to provide a guard for carpenters planes of the above character, which will be durable and effi- 35 cient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, ar-

40 rangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which drawing:

Figure l is a central, longitudinal, sectional 45 view through a plane, with my novel guard connected therewith, the view being taken substantially on the line l--I of Figure 2, looking in the direction of the arrows. I

Figure 2 is a transverse, sectional view through 50 the plane with my guard thereon, taken on the line 2- 2 of Figure 1, looking in the direction of the arrows. a

Figure 3 is a perspective view of my guard "removed from the plane. 55 Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter G generally indicates my novel guard for a plane P.

The plane P forms no part of my present in- 5 vention and can be of any desired construction, make, or size, and, as illustrated, the same includes the stock 5 carrying the rear handle 6 and the front hand-rest and guide knob I, The stock 5 includes the lower flat plate 8 having upstanding side walls or flanges 9. The plate 8 is slotted transversely, as at II], for receiving the blade or knife H, and the stock carries a suitable seat for the blade or knife and an adjusting and locking means therefor. The sharpened end of the blade or knife H protrudes through the slot Ill, and my novel guard G is adapted to protect said sharpened end against injury.

The guard G can be made from any desired material, such as sheet metal, and the same is bent into a substantial U-shape in cross section to provide a bottom guard wall t5 and upstanding side walls t6 and Ill. These side walls I6 and I! are shaped to snugly engage the outer sides of the side walls 9 of the plane stock 5, andth'e upper edges of the walls H6 and ll of the guard. G are shaped to conform to the configuration of the upper edges of the side walls of the stock. The upper edges of the side walls It and I! of the guard are also provided with inturned flanges M8 for extending over and gripping the side walls 9 of the stock 5, whereby the guard will be effectively held on the plane.

The bottom Wall I 5 adjacent its longitudinal 1 sides is offset to provide shoulders Ill, and these shoulders engage the lower face of the bottom plate 8 of the stock 5 on each side of the blade or knife I l. These shoulders IS space the b0 tom wall l5 from the sharpened edge of the blade or knife, so that said wall l5 will not dull or mar the edge of the knife or blade.

If desired, the front edge of the wall I5 can be provided with an upstanding lip 20 for closing the front of the guard and for engaging the lower surface of the plate 8 of the stock. L

From the foregoing description, it can be seen that I have provided a guard of exceptionally simple and durable character, which can be easily slipped on the plane or easily removed therefrom, and which will effectively protect the cutting edge of the plane knife or blade when the guard is associated with the plane.

While I have illustrated one form of my guard, it is to be understood that the same can be made in various manners, providing the construction does not depart from the spirit or scope of the claims.

What I claim as new is:

1. The combination with a plane including a stock having a bottom plate and upstanding side walls, and a blade having a sharpened end extending through the bottom plate, of a guard for the sharpened edge of the blade including a body substantially U-shaped in cross section having a bottom wall and upstanding side walls, means carried by the side walls for engaging the side walls of the stock and for holding the guard on the stock, means carried by the bottom wall for spacing the bottom wall from the lower surf-ace of the bottom plalte of the stock and the sharpened edge of the blade, whereby to protect said sharpened edge.

2. As a new article of manufacture, a guard for the sharpened edges of the blades of planes comprising, a sheet metal body of a substantial U-shape in cross section including upstanding side walls and a connecting bottom wall, inwardly extending flanges formed on the side walls for engaging over the upper edges of the sides of the plane to hold the guard in place on the plane, said bottom wall extending trans.- versely across the lower face of the plane and having parts engaging said lower face, and a part for enclosing the sharpened edge of the blade of the plane.
