TOOL GUARD Original Filed Aug. 22, 1934 2 Sheets-Sheet 2 I nventor forcloa 6,j a/w er Attorney Patented Sept. 8, 1936 UNITED STATES PATENT OFFICE Application August 22, 1934, Serial No. 741,022 Renewed February 17, 1936 dclaims.

This invention relates to guards for tools and consists in the provision of a guard or sheath adapted to receive and protect edged tools such as, for example, chisels, bits, and analogous tools.

An object of the invention is to provide a guard or sheath of the character above mentioned that is characterized by simplicity and economy of structure. 1

The invention, together with its objects and advantages, will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure l is a side elevational view illustrating an application of the guard or sheath.

Figure 2 is a top plan view thereof.

Figure 3 is an end elevational view thereof.

Figure 4 is a perspective view of the forward end of the sheath.

Figure 5 is a perspective view of an end strap forming part of the invention.

Figure 6 is a sectional view through a slightly modified form of the invention.

Figure 'l is a bottom plan view of the form of the inventionshown in Figure 6.

Figure 8 is an end elevational view of the second form of sheath.

Referring to the drawings by reference numerals, and reference being had particularly to the form of the invention shown in Figures 1 to 5 inclusive, it will be seen that the guard or sheath indicated generally by the reference numeral I0 is formed from a single oblong blank of metal or other suitable material cut, shaped, and dimensioned to provide two complemental sections Ii and i2 integrally joined at one end to provide a closed end It for the sheath. At the end I3 the section i2 is slightly curved away from the section I I to provide inwardly from the end l3 a stop it, and due to the inherent resiliency of the material used the section I! is normally urged in a resilient manner away from the section II of the scabbard or sheath.

The section I: has downturned longitudinal edge portions or flanges i5 directed towards the section I l and adapted to engage the sides of the blade of the tool inserted in the scabbard for retaining the tool properly within the scabbard or sheath.

At the open end thereof, that is, at the end thereof opposite to the closed end l3, the sections II and I2 oi the scaobard are connected through the medium of a strap l6 that has an intermediate portion thereof secured in any suitable manner transversely to the section II. opposite end portions extending between or bridging the space be- In actual practice, the blade iii of the tool is 10 inserted in the sheath in an obvious manner and at the beveled edge end thereof the tool will engage the stop I4 in such a manner as to prevent the sharp edge of the tool from coming into forceful contact with the metal or material from which 15 the sheath or scabbard is formed. In this connection, it will be noted that the working or sharp edge of the blade of the tool when the tool is fully inserted in the scabbard will come into contact with the strip l1 which latter, as before stated, is of an absorbent material and may be provided with oil or any other suitable anti-rust solution for protecting the edge of the blade of the tool against rust and corrosion.

The form of the invention shown in Figures 6 to 8 inclusive is substantially identical with that shown in Figures 1 to 5 inclusive with the exception that in the second'form of the invention, the strap i6 is dispensed with and the flanges i541 of the section i2 at the open'end of the scabbard or sheath are provided with integral spring fingers 20 that at their free ends are formed with heads 2! adapted to engage the section II of the sheath in a manner clearly shown in Figure 8 to hold the sheath in what may be termed a closed condition. In this connection, it will be noted that the section I20, of the scabbard or sheath is transversely curved as clearly shown in Figure 8 and to facilitate the withdrawal of the blade l8 of the tool from the scabbard the operator with the thumb may exert a pressure on the section l2a adjacent the open end of the Scabbard in a manner to flex the section i2a inwardly toward the section Na and thereby cause the heads 2| of the spring fingers 20 to spread outwardly out of engagement with the sec tion Ha. thus permitting, upon release of said pressure, the section I2a, due to its inherent resiliency, to spring outwardly away from thesection Ila or, as may be stated, opening the scabbard in a manner to permit the blade of the tool to be to provide two complemental sections, one of said sections at the free end thereoi having integral resilient tongues at opposite sides thereof and provided with heads for engaging the other of the sections to releasably retain the sections against the tendency thereof to spread apart due to the inherent resiliency of said sections.

2. A scabbard for tool blades formed from an oblong strip of metal bent intermediate its ends to provide two complemental sections. one of said sections at the free end thereof having integral resilient tongues at opposite sides thereof and provided with heads for engaging the other of the sections to releasably retain the sections against the tendency thereof to spread apart due to the inherent resiliency of said sections, said one section being curved transversely as and for the purpose specified.

3. A scabbard for tool blades formed from a singleelongatedbiankofsheetmetalandhavins a pair of elongated side sections integral at one end and mutually separated at the longitudinal side edges thereof. one of said sections having integral side flanges extending longitudinally thereof for guiding the blade passed into the scabbard between said side sections, and means at the free ends of the side sections and engaging therewith to limit the normal tendency of the sections to spring outwardly from one another due to the inherent resiliency of the material used.

4. A tool blade scabbard of sheet metal having elongated side sections integral at one end and mutually separated at the longitudinal side edges thereof, one of said sections having integral side flanges extending for substantially the 15 full length thereof and projecting therefrom toward the other of said sections, and a strap of substantial loop form embracing the side sections adjacent the free ends thereof.
