JOHN A. RYDEN, OF OMAHA, NEBRASKA.

HOOF-NIPPERS.

its. season.

To all whom it may concern:

tie it known that. I. Join: A. Ri'lll-IN. a citizen ol the tlnited States. residing at Omaha. in the county ot llougg'his and I' tate oi i\'ebraslta, have invented certain new and useful improvements in llooli-Nippers. ol which the following is a speeitiratiou.

This invention relates to an improvtanent in hoof nippers and has for provision at means for limiting the movement of the cutting blades in (ilt'tl'tiOIlSlth ward each other, to preserve the sharpness of their edges; also to provide means for controlling the frictional contact of the arms.

Vith these and other objects in view the invention presents a novel combination and arrangement of parts as described herein, and in the appended claim and as illustrated in the drawing. it being understmd that changes in the form, proportion. size, and minor details may be made within the scope of the claim Without departing from the spirit or sacrificing; any of the advantages of the invention.

in the drawing, Figure 1 is a side view of a pair of hoot nippers eontructod in neeordance with my invention. Fig. is t broken away view, somewhat enlarged o." the head of the nippers for clearly showing the devices. l ig. ll is a. sectional view on line (i b of .l ig. 2. Figs. 4 and 5 are side views oi the bolt. l in's. (l and T are end views of the yoke to show the openings therein. Fig. 8 is a side view of parts shown in l igzti Fig. it is an end View ol the adjusting nut employed.

Referring now to tho druwii'lg tor a more particular descript on, numeral 1 indieates a pair of hoot nippers, comprising arms or handles 2, each having at its forward end a head or jaw 3 :l'm-med reotai'igular in cross section and provided with a. transverse terminal blade or euttinp; edge 4;, the handles of said nippers being disposed eroaswiso and provided with a connection or pivotal mounting."between the-handles and jawsnas by bolt 5, said bolt; having a head with parallel, facets (l fOill'ltZtl thereon. Jaws 3 are bowed outwardly between their [[JiVOitli mounting 5 and cutting odn'esit. tltlt preterably have their outer and inner surfaces formed convergent; 'uear these edges. its thus described, jaws 3 may move ll] direotions toward or away from eaeh other. in order to prevent blades 4 from being dulled its object the Specification of Letters Patent.

with each ol her. au angular retross,groove or depression T is termed in and opening upon the inner side of eat-h jaw It, said recess or groove having a eontaot-wall (host :-.howu in t ig. disposed sul'istantially parallel with a tin or plane extending between terminal it of the blad and pivot or bolt 5; and l provis'le the stridiugnieee loop or yoke 8 a topted to have a seating in grooves 'i". ft'hen jaws 53 move in directions towaid each other, the longitudinal body f of the yoke engaged by the angular walls of the grooves, and limits the movemenh of the jaws, and. pro vents actual eontaet of the Yoko by striking against. or eoutaetiu iJi-[tClG-S. arms 10 and L1 are disposed transversely with reference to body 9 and term the ten minals of the yoke. Arm it) is provided with an angular opening 12. Bolt is provided intermediate its body and head with :larcts 13. Arm to of the yoke is adapted to have a Eating; between the that face ll oi" one of arms 2'and the. head of the bolt, the angular opening 153' registering with laeets 3. Arm ll of the yoke has the round open mg 1.5, and when the parts are assembled the bolt traverses this opening.

it an advantage t6 have the eontaeting sides of arms 2 held closely together at their ivotal tllt'llllltiillg. These eonta :ting surlaces wear a way alter eonsidera e use, and it; is desirable to have. adjustable securing the arms wit it a. greater or lesser do gree of pressure, nut lti upon the screw-bolt, answerino' this purpose. By reason of the construction as described it; will be seen. that; bolt 5 will not rotate relative to the yoke means to r arms. since its facets l3 engage the wells 0t netting l2 ol. arm to, and this is a desiredv result. to prevent rotation or looseni of the out. As ordinarily used, hoot uippers re quire sharp blades. Aeeording to former constructions when the inudement; is used, the edges of the blades strike against each other, resulting in their inniiairnnznti. tiilinee, in the present construction. the lolades approach closely to eaeh other but do not make contact, no injury occurs to their sharpened edges.

To assemble the parts, a tter the y eld: is placed with its body it in grooves T of the jaws, bolt. 5 i

"ends, each of said handles having a curved jaw with a transverse terminal cutting blade and formed upon its inner side with a groove having a contact-Wall disposed substantially parallel with a plane extending between said terminal blade and said pivotal mounting; a striding piece disposed intermediate the grooves of said handles adapted to engage said contact-Walls and having arms mounted upon the outer sides of said handles.

In testimony whereof I have affixed my signature 1n presence of two witnesses.
