To all whom it may concern:

Be it known that I, GEORGE W. PRA'rr, a citizen of the United States, residing at Oakland, in the county of Alameda and State, of California, have invented a new and useful Policemans Nippers and Handcuffs Combined, of which-the following is a specification. v

My invention relates to improvements in combined policemens nippers and handcufis 'in which a tubular stock connects an automatically acting hand-cuflt' with a hollow handle within which a jointed hand-cull may be compactly folded and permit thedevice to be used as a, policemans" nippers, Thesfolded hand-cull may when desired be extended and caused to assumeithe formof a hand-cufi which, in conjunctionwith the automatically actuated hand-cuffs, serves as a pair of hand-cuffs.

The objects of my improvement are, to provide policemens nippers which may be quickly converted to a pair of handcuffs second, to adjust the cuffs to large or small wrists and to lock the two cufl:'s when inuse so that they can not be unlocked without'the useof a suitably fitted key; third, to provide construction whereby, by unlocking one culf, both cuffs may be opened and removed without difficulty and one of the cuflfs folded down into a hollow handle transversely disposed with' respect to the tubular connecting stock, the whole device simple and cheap in construction, light in weight, and easily operated. I attain these objects by the mechanism illustrated in the accompanying drawings, in '.which 1 Figure 1 is a vertical section of the dev ce taken on the plane of the line 2, 2, of Fig. 3. 9 Fig.2 is a vertical transverse section of the complete device taken on the plane of line 4, 4, of Fig. 1. Fig. 3 is an edge elevation of the same.

the sickel shaped tongue 8, is serrated or Similar numeral reference characters re- 8 are suitably shaped teeth formed on the under side ofthe retaining pawl 10 which is adapted to fit and vertically move in a correspondingly shaped cavity 11.

Vertically projecting from the top of the retaining pawl 10 is a rod 12 the lower part of which isinclosed by a coiledspring 13 the foot of whichrests on top of the retam ng pa 0, the t p of sa spring pressingupward against. he; t p of. the spring cavity 14, this arrangement serving to force the rod 12 and retainingpawl 10 into contact with theteeth of the tongue 8. Contacting with the top. endof the rod 12 is the free end of a fia-p 15 which is pivoted at 16 to a transverse rod-supported by the vertical walls of the hollow handle 17, the ofliceof which will hereinafter be fully set forth. The hollow handle 17 is transversely disposed. on the tubular stock 5. Two rods .18, 19, transversely traverse the said handle, the rod 18'serving as pivot for one end of the S-shaped lever 20, the rod 19 serving as 'pivot for one end of the S-shaped lever 21,

the free ends of both said levers 'being I which incloses a pinion 25 provided'with I teeth of a pitch suitable to engage with the teeth on the back of the extension 22. The housing 24 also carries a spring pawl one end of which issecured to the inside top of said housing. The free end of the spring pawl 26 contacts with the teeth of the pinion 25 so as to prevent the latter from revolving to the right, but willallow it to revolve in the opposite direction, so as to permit the entrance of the toothed extension 22, within the housing 24 when the extensions 22, 23, are assuming the position {shown by the dotted lines at the top of Fig. 1. In this position too, the enlargement 27 on' the pivotal end of the S-shaped lever 20 will contact with the flap 15 and firmly force it on to the top end of the rod 12, and prevent the teeth of the connecting block 10 from severing engagement with the teeth of the tongue 8. On folding the lever 20 down into the handle 17 the cam-shaped enlargement 27 will be withdrawn from contact with the flap 15, when a suitable key introduced in the key-hole 28 can be caused to lift the free end of the spring pawl 26 from contact with the teeth of the pinion 25 and permit disengagement of the teeth of the block pawl 10 from the teeth of the tongue 8 by lifting, by the end of the finger, 0n the pin 29 which projects from the rod 12 through the wall of the tubular shank 5. The orifice through which said pin 29 projects is vertically slotted to admit of vertical movement enough to separate the teeth of the block pawl 10 from the teeth of the tongue 8, when the latter can be easily withdrawn, thus liberating the wrist inclosed by the cuff 6.

Having thus explained the nature of the invention, and described an operative manner of constructing and using the same although without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what is claimed 1s 1. In police nippers in combination a tubular stock, a transverse hollow handle connected therewith, an articulated handcufi connected to said hollow handle, and adapted to be folded therein; a flap pivoted in said hollow handle, a cam on one of the connected ends of said articulated handcufl', and adapted to actuate said flap; a rod connected to a retaining pawl, slidably arranged in the tube of said tubular stock; a pin connected to said rod, said ,pin projecting through a slot in the wall of said tubular stock, a spiral spring surrounding the lower end of said rod, teeth on the under face of said retaining pawl, a bifurcated semi-circular part connected, to the lower end of said tubular stock, a sickle-shaped ton e, the lower end of which is pivoted to an in the opening of said bifurcated part, teeth on the upper side of said tongue, said teeth engaging with the teeth of said retaining pawl, said tongue adapted to swing in a complete circle through said bifurcated part, substantially as described.
