Patented lune 3, 1924.
DAVID M. WALL, or rnovnENeE, RHODE ISLAND.
BLADE PENDANT.
Application mea August is, 1922. serial No. 532,711.
T all whom t may concern:
Be it known that I, DAVID M. VALL, a citizen of the United States, residing at Providence, in the countv of Providence and State of Rhode Island, have invented certain new and useful Improvements in Blade Pendants, of which the following is a specication. j
My invention relates to blade pendants l0 and has for its essential objects adaptability for suspension from a chain; the combination of a pendant with a cutting implement; utility for the use of blade of different types, shapes, and sizes; capacity for substitutlon of blades; security; clamping efficiency; facility of operation; and inexpensiveness of construction.
To the a'bove ends essentially my invention consists in such parts and 1n such com* binations of parts as fall' within the scope `of the appended claims.
In the accompanying drawings which form a part of the specification- Figure 1 is a side elevation of a pendant embodying my invention,
Figure 2, a sect-ion on line 2 2 of Figure 1,
Figure 3, a section on line. 3-3 of Figure 2,
Figure 4, a like section of the same in open position, and
Figure 5, a perspective view of the clamping member.
Like reference characters indicate like parts throughout the views. j
In detail my device comprises an oblong flat tubular sheet metal casing 7 open at both ends having parallel front and rear walls 8 and preferably transversely curved side walls 9 provided near their upper eX tremities with stops or projections 11 formed Aby indentation. Detachable caps 13 and 111 fit over the top and bottom ends respectively of the casing and form closures. These caps while slidably engaged with the casing have a suiiicient frictional contact therewith to prevent accidental disengagement. In an integral knob 15 on the cap 13' is a suspension ring 16 to afford attachment to a chain.
Slidably mounted in the casing is a clamp member 17 cooperating with the front and back sides of the casing to retain a blade,
in this instance a perforated two edged razor blade 18, although obviously an unperforated'single edge blade may be carried with equal facility. In detail the clamping member is constructed by cutting and bending upby suitable tools from a piece of resilient sheet metal an oblong blank which is centrally bent to form an end substantially closed loop 20 integral with the upper ends of two slightly diverging resilient arms 21, convexe-concave in cross section, having integral with their lower portions laterally extending wings or plates 22 of a width to slide with their lateral edges in contact with the casing sides 9 until stopped by contact with the projections 11. The plates 22 have preferably centrally disposed vertical outwardly swelled portions 24 continuous with the arms 21 and partaking of the outward inclination of the latter. These swells or shoulders engage the front and rear walls of the casing, and as they slide into the casing are compressed so as to force the plates 22 into contact or adjacent each other.
The operation of my device is as follows. A blade is manually inserted between the arms 21 of the clamping member while the latter is entirely removed from the casing. By the finger and thumb the operator compresses the plates 22 to temporarily hold the'blade, and the member 7 is then slid into the casing with the loop 20 uppermost, and the cap 14 applied as shown in Figure 3. When it is desired to use the knife the casing is withdrawn from the cap 13 and the loop 2() is grasped by the thumb and finger and drawn upwardly until the plates contact with the projections 11 and the parts assume the position shown in Figure 4 ready for cutting purposes. The blade is held tightly clamped between the edges of the arms 21 by virtue of their compression by the front and back walls of the casing.
1. In a blade pendant, a casing provided with open ends, detachable caps on the ends of the casing, and a compressible clamp member slidably mounted in the casing operable by contact with the casing to frictionally clamp the blade. v
2. In a blade pendant, a casing provided with open ends, detachable caps on the ends of the casing, a compressible clamp member of greater length than the easing slidably mounted in the casing to retionally clamp the blade and compressed by the casing.
3. In a blade pendant, a lat casing provided With open ends, and a clamping member comprising divergng resilient clamping arms enolosable in the casing, a loop eonnecting the upper ends of the arms above the Casing, and plates rigid with the lower ends of the arms engageable with the walls of the easing to compress the arms to frictonally clamp the blade.
In testimony Whereofl have alixed my signature.
