BARNARD L. WARD, OF OTTUMWA, IOWA.

MANACLE Specification of Letters Patent. Application filed March 28, 1907. Serial No. 365,178.

Patented April 28, 1908.

To all whom it may concern:

Be it known that I, BARNARD L. WARD,'a

. citizen of the United States, residing at ttumwa, in the county of VlapelloA and State of Iowa, have invented certain new and use-y ful Improvements iny Manacles; and I' do declare the following to be a full, clear, and exact description o? A p will enable others skilled in the art to which it appertains to-make and use the same, reference being had to the accompanying draw` ings, and to the letters and iigures of reference marked thereon, which form a part of this specification.l y

My present invention relates to manacles, and more particularly to an improved means for locking and releasing the clamp members of such a device; this invention being an improvement on the device shown in Letters Patent No. 778,761, issued December 27, 1904, to Axel L. Nelson, the entire right to which invention 'and Letters Patent are now owned by me.

The Vobject of my invention is to provide a manacle of the construction shown in the above mentioned patent, in which the clampv members are automatically locked when applied to the wrist, but in vwhich the locking parts are n ot accessible to one held thereby, although readily operated by the custodian.

The improved structure is illustrated in.'

the accom anying drawings, in which,-

Figure is a view in side elevation of a Amanacle bearing my improvements. Fig. II is an end view of same. Fig. III is a view in longitudinal section Aon the line III-III, Fig. II. Fig. IV is a transverse sectional view on the line IIL-IV, Fig. I.

The numerals 1 represent the clamp members which are curved as shown, and provided at one end with the reversely bowed shank portions 2, having the arcuate slots 3.

4 is the head portion having the grip members5, and a bifurcated neck, the'arms 6 of which are slotted at 7, and embrace the clamp member Shanks. Projecting through a channel 4: in the head-4 is a stem 8, the inner end. of which extends' between shanks 2 and is provided with a slot 9, while one of its edges is rovided with ratchet teeth 10.

Xtending through the neck arms at about their longitudinal center, and also through perforations in the ends of Shanks A2l and through the slot in stem 8 is a pivot pin 11,

the invention, such as.

which anchors the clamp members to the head, and over which the stem is adapted to travel.

Extending through the slots 7 in the head neck arms, through. the arcuate slots in the clamp member shanks, and through a perforation in the end of stem 8 is a loose pin 12 adapted to travel in said slots, but provided with the keeperheads 18 to prevent its lateral displacement. p

Projecting through, and pivoted in a re -cess 14 in head 4 which communicates with thechanneli is a lever 15, the lower end of which is provided with teeth 1.6 adapted for engagement with the teeth 10 on stem 8, and at its outer end with the thumb piece 17.

18 is a hat spring rigidly secured to the outer end of lever 15 yand bearing against stem 8 in a manner to yieldingly retain the upper end of the lever away` from the stem and the lower end thereof inwardly with its teeth in engagement with the teeth on said stem.

19is a seat sunk into the head around the stem channel and 20 is a compression spring resting in vsaid seat and surrounding'stem 8,

`with its upper end bearing against a button 21'on the outer end of said stem.

In use, the upper end of the catch lever is pressed inwardly to rock its lower toothed end out of engagement with the stem ratchet, when the compression spring 20 forces the stem outwardly by its tension against button 21, thereby drawing the loose pin 12 out- Wardly and causing the clamp members to spread during the travel ofthe pin through the arcuate slots in the clamp member Shanks. By` grasping the handle grips by the lingers, with the button in the palm, and closing th hand, the stem will be forced inwardly, forcing the loose pin through the arcuate slots in the clamp member Shanks, and drawin the clamp members together.- The catch Ie being free, the lower toothed end thereof is held in yielding contact with the ratchet teeth tions projecting laterally from said head,

yoke arms projecting from said head intermediate said handle portions, clamp arms carried by said yoke arms, an actuating stem projecting through said stem channel and connectedJ with said clamp members, a catch lever pivoted to said head and projecting through said lever recess, a stem locking member on one of said lever arms, an operating head on the opposite lever arm, the latter located above said handle portions, and means for normally retaining said locking member in engagement With said stem.

2. A manacle comprising a head having a lever recess, a neck projecting from said head and provided with a stem channel, and conimunicating with the recess in said head, clamp members carried by said neck, an actuating stem extending through said channel and having a connection With the clamp members, ratchet teeth on said stem, and a catch lever pivoted in said recess and normally held in yielding locking engagement with said stem.

In testimony whereof I affix my signature in presence of-two witnesses.

BARNARD L. WARD.
