T 0 allay/50172 it may concern:

Be it known that we, RUDOLPH FLIGK and l/VALTER M. BROWNING, citizens of the United States, and residents, respectively, of Sheridan, in the county of Madison and State "of Montana, and Glasgow, in the county "of Valley and State of Montana, have invented certain new and useful Improvements in Docking Machines, of which the following isaspecification. I

This invention relates to docking machines for lambs.

.-An important object is to provide a docking machine for lambs having. two pairs of cutting blades, onepa'ir of which may be heated while the other pair is in use.

A further object of the invention is to provide simple means whereby either pair of blades may be'arranged in an operative position when the other pair becomes cool.

Another object of the invention is to provide a docking machine which is economical to operate, of highly simplified construction and cheap to manufacture Other objects and advantages of the in vention will be apparent during the course of the following description.

In the accompanying drawing forming part of'this' application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of the improved docking machine applied to a suitable support. T

Figure 2 is a plan view of the machine applied. I

Figure 3 is a vertical sectional view through the machine, the View illustrating a pair of coacting blades.

Figure 4 is a transverse sectional viewtaken on line H of Figure 3.

- Figure 5 is a perspective of an insulating sheet embodied in the invention.

Figure 6 is a perspective of a relatively movable disk embodied in the invention.

In the drawing wherein for the purpose ofi'llustration is shown a preferred embodi ment of the invention, the numeral 5 desig nates an elongated casing which is coma posed of sections 6 and 7 having inwardly directed flanges connected by means of fastening bolts 8. The fastening bolts 8 of course extend through the sides of'the sec tions 6 and 7 and cause the edges of the disks having cutting inwardly projecting flanges to lie snugly in contact with each other. The casing 5 may be secured to asuitable support 10 by means of clamps 11 and is preferably secured in an inclined position in the manner illustrated in Figures 1 and 3.

With reference to Figure 3 it will be observed that the casing 5 is provided with alongitudinally extending heating chamber which is supplied withheatifrom a gasoline torch 12 of any desired type. The mouth 13 of the torch 12 discharges into an inlet opening 15 at the lower portion of the casing. The heat from the torch 12 is directed through the casing and more particularly into the heating chamber and is discharged through an outlet opening 16 inthe upper portion of the casing, the said outlet opening being provided by cutting away portions of the inwardly extending flanges of the casing. Suitable hangers 17 may be provided for supporting the torch 12 in its proper position with relation to the heating chamber. Vith reference to the foregoing it will be seen that a high degree of heat is passed through the heating chamber of the casing in the use of the machine. 1

A suitable metallic plate 19 is arranged between the section 7 and the support 10 and has inwardly extending flanges '20 to form a, supporting means for a sheet of insulating material 21 such as asbestos. The insulating sheet 21 prevents the casing from burning-the support 10. 7

The docking means includes a pair of cutting disks one of which is movable with.

relation to the other. However both of the disks may be rotated for arranging a new pair of blades in an operative positionand for again heating the pair of blades which may have become cool. i p t -he relatively movable blade is in the nature of a disk having oppositely arranged segments provided with cutting edges 23. The movable disk 22 has its oppositely arranged segments provided with thickened portions 24 which provide relativelywide cutting edges and which also provide stop shoulders 25. The cutting blades 23 which are two in number cooperate with similar blades of the relatively stationary disk.

With particular reference to Figure-6 it will be noted that the movable blade 22 has its hub secured to an annular flange 28. by means of rivets 29, the said. annular flange being formed at one end of a sleeve bearing 30. The sleeve bearing receives the attaching portion 31 of a pair of oppositely arranged arms 32 by means of whichthe bearingSO may be manually rotated for operating the movable disk 22. A'handle 34 has its forward portion provided with a socket 35 which receives one of the arms 32 and which is adapted to be rocked for rotating the disk a limited extent.

The sleeve bearing 30 is rotatably extend.

7 contact with the segments of the disk 22.

One'edge portion of each segment of the stationary disk 40 is thickened as indicated at 4]. to provide a pair of stop shoulders 42 which engage the adjacent edges'of the movable'segments and thereby limit the rota-- tion of one disk with relation to the other.

7 side of the shaft.

The thickened portions 41 of which there are two provide cutting edges or blades 43 with which the movable cutting edges 23 coact', When the movable blade 22 is operated the blades 23 and 43 are brought into contact for performing the desired operation and they do not pass each other. The relatively stationary blade which is designated by the numeral 40 has its hub secured to a flange. 44 by means of rivets, the said flange being formed at one end of a shaft 45. The shaft 45 is extended through the sleeve bearing 30 and has one end slotted as indicated at 46. A locking handle 47 is pivotally connectedto the slotted portion of the head 45 and may be swung to either Vith reference to jFig-,

ures 1 and 4it will be noted that the locking handleis adapted to be received within a slot 50 in a laterally projecting bracket 51 carried by the section 6. hen the lock ing handle 47 is thus secured to the bracket 51 the shaft 45 is prevented from rotating.

With the shaft 45 thus held against rotation'the disk 40 is held in a relatively stationary position. However, the disk 22 is permitted to move sothat the blades 23 and 43 may be brought into contact.

In operation the torch is mounted so that the heatfrom the same will be directed into the heating chamber in the casing 5. The heat thus directed through the heating chamber will be caused to heat the lower portions of the relatively stationary and movable disks since the disks have their lower portions received within said champosite side of the shaft 45 whereupon the shaft 45 is rotated and the locking handle 47 again engaged with the bracket 51. When the shaft 45 is thus rotated both of the disks are rotated for exposing a new;

pair of cutting blades and for subjecting the cooled blades to the action of the heat.

A docking machine constructed in ac cordance with this invention operates with no. loss of blood to the animal since the wound is seared and quickly heals Also the machine may be rapidly operated since it is merely necessary toswing the handle 34 in the direction indicated by the arrow in Figure 1 for contacting the blades 23 and 43. Actual tests performed on a large herd of lambs demonstrated that the machine can be rapidly'operated and will cause no loss of blood or weight by the animals.
