SHEEP-SHEARING MACHINE.
Specification of Letters Patent.
Patented Dec. 1033332.
Application filed June 5, 1912. Serial No. 701,876.
for the purpose of distributing the tension from the fork of the shear evenly, to the cutter thereof.
Hitherto, in most sheep shearing machines the prongs of the fork have been turned over downward at their outer extremities to provide for a bearing surface that shall press upon the surface of the cutter and by so doing keep it suitably positioned upon the comb of the shear. But all. cutters are not made exactly alike especially in regard to depth, the distance between the upper surfaces and. the lower or cutting edges varying. If the depth of one more than another there will be varying pressure on the cutter by the fork tips when the cutters are changed and consequently more vibration and less even cutting.
In our invention we propose to dispense with the turned down extremities and to use instead knuckle plates upon the prongs of the fork. These plates are attached loosely thereto and will be susceptible of a slight swinging motion thereon to accommodate their bearing surfaces to that of the cutter. But in to "fully understaiui the invention reference will b made to the accompanying drawings, i uich,
Figure l a plan view of part of a sheep shears with the knuckle pistes in position on the fork. Fig. 2 is underneath view of a fork with the invention attached. 3 shows the end of a rabbeted fork prepared for the reception of the plates. Fig. 4 is a side elevation of the same. Fig. 5 is a sectional view of the fork end showing the convex bearing surface, and Fig. 5 is a like view but showing the convexity on the fork taking into a corresponding concavity on the knuckle plate. 4
The fork 6 isof ordinary construction save that the ends of the prongs are adapted. The fork to be used with our invention. I comes over the cutter 7 and the latter reclp rocates over and upon the comb 8.
In carrying this invention into eiiect'we arrange upon the prong ends the U-shaped plates 9 which can be loosely hung in the prongs on the rivets 10. The horizontal part of each member 9 is plane surfaced and its sharp edges are preferably groundv ofi' to avoid possible interference withthe'wool fiber. Upon the underneath surface 6f each of the prongs is'a slightconvexity 13:2
which comes close up to the inberiorysurfacej of the members 9 andiupon which the same, will hear when the'tension is applied. I
In Fig 5* we ,showa pure knuckle joint, in which the convexity 12 on the fork will? roll in a corresponding. concavity in the iin l terior of plate 9, and this is the form prefer to use.
We preferably rabbet or recess the pron of the fork as shown in Fig. 3" for the recep 5 tion of the plates 3* which loosely hangon 10. To permit the plates to swing slightly when in position, the sides of the recesses- 11 are adepted for that purpose and areal little inclined so as to give the requiredi clearance. The under surface of the fork. is in this case also provided with convexities 12 to come into connection with plate.
9 on pressure being applied to the fork;
When this takes place and the plate presses upon the cutter the strain upon the bearing pins 10 will be taken up by'the c011 vexities. There will be a sufficient diiierence between the diameters of the rivets 10 and the holes drilled fortheir reception in the fork to give the necessary clearance and to permit of the bearing being taken in the .muckle.
'lhe member 9 being arranged as described w l edapt itself to the cutter upon which it 2 lie iiat and being directly over the cutting edgesit will hold the cutter firmly and thus minimize the vibration when tension is applied. T he worn out plates 9 can be easily replaced and at less cost than is incurred in providing a new fork.
Having now particularly described and ascertained the nature of our said invent-ion and in what manner the same is to be performed, we declare that what we claim is 1. In a sheep shearing machine, the con bination, with the fork of the machine, of a convexity, provided on each prohg of loosely attached to each prong, and havin a. flat yoke'part adapted to bear onthe a jace'nt convexity when tension is applied to the. fork.
2. In'asheep shearing machine, the combination with the forks-0f the same of U- shaped plates loosely hung inthe fork prongs the lower part of the plates passing below the-same and being so formed as to makeknuckle joints-with gonvexities on the convexity on each prong betweenthe re- 7 cesses thereof, and a U-shaped plate on each prong and having its .arms loosely fastened insaid recesses, and itsyoke-part adapted to lie against the adjacent convexity when tensionis "applied to the fork.
In testimony whereof, We have signed our names to this specification in the presence of two subscribing witnesses.
