REPAIR DEVICE FOR CREAM SEPARATOR DISKS Filed Feb. 15, 1954 2 Sheets-Sheet 2 Inventor z/m rz/zzamm f atentecl Feb. 1 8, 1933 UNITED STATES PATENT OFFICE REPAIR DEVICE FOR CREAM SEPARATOR DISKS This invention relates to a repair device for cream separator disks, the general object of the invention being to provide means for facilitating repairing of the disks which have become worn by use and disfigured and corroded by misuse.

This invention also consists in certain other features of .construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which: Figure 1 is a side View of the device.

Figure 2 is a front view thereof. Figure 3 is a top plan view.

. Figure 4 is a section on line 4-4 of Figure 1.

Figure 5 is an elevation with parts broken ,away showing the type of disk with which the invention is used.

As shown in these drawings, the body A of the .2 device is cast in one piece and is formed at one side thereof with an arm I, the rear part of which curves downwardly to the point where it joins the top part of the body and the front end of this arm is provided with a depending part 2 which is formed with a vertical bore and with a notch 3 which opens into the bore and through the top part of the arm. A plunger rod 4 passes through the bore and has a head 5 at its upper end, with its lower end threaded to receive the nut ii and the lock nut E. This nut 6 has its lower part tapered, as shown, and the lower end of the rod it is tapered, as shown at 8, with its extremity flat.

A pin 9 extends from the rod 3 and passes through the notch and serves to prevent rotary movement of the rod and thus facilitates the adjustment of the two nuts. An upwardly extending projection It is formed on the upper face of the body and is located under and spaced from the part 2 of the arm and has its upper end rounded, as shown at" H, and this projection has a bore passing through its upper end and said bore receives a headed pin l2, the shank of which is encircled by a coiled spring 63 which tends to hold the head of the pin flush with the top of the projection.

The type of disk with which this invention is used is shown at B in Figure 5 and the indentures in the disk are shown at b.

The lower, tapered end of the nut 6 acts as a stop for limiting downward movement of the rod of cream separators.

and this device will restore the indentures to their original shape when the same have been worn down by use. The rounded top of the projection I0 prevents breakage of the curvature of a disk being operated on by the device and the flat top 10 of the projection acts as a guide for the disk while the disk is being punched. As will be understood, the pressing of the metal into the bore of the projection Ii] by the tapered end of the rod 4 will reform the indenture and when 15 the bottom part of the nut 6 strikes the disk, further downward movement is prevented so that by adjusting this nut and then looking it in position by the lock nut 'l, indentures of the proper size can be re-formed in the disk. The pressure 20 of the spring I3 on the headed pin and the flat extremity at the lower end of the rod l insures a flat point to the indenture. By tapering the lower part of the nut 6, the breakage of the curvature of the disk, when the punch point 25 strikes the disk, is prevented. The tapered lower end of the rod l will enter the bore of the projection It and this feature will prevent the parts from cutting or breaking the disk when the indenture is being formed. 3

The top part of the body is flat and this top part is extended at one side, as shown at M, to form a point on the anvil part and the sides of the top part of the body are formed with the curved recesses l5 and the extremity of the 35 part l4 slopes downwardly and outwardly, as shown at I6. Thus an anvil mandrel is formed of substantially conical shape so as to fit most all disks made and the beveled. part [6 can be used to restore the inside bevel of the disk. 40

A diagonally arranged hole l'l passes from one side of the body through the other to receive a shaft l8 which is held in place by the pins IS. The lower end of the shaft carries a buffer wheel 28 and a crank handle 2| is attached to the other 45 end of the shaft.

This buffer wheel is used for removing rust and corrosion from the disks .and the anvil can be used for various purposes, such as straightening indentures made too deep or irregular dents or bends made by abuse.

A threaded hole 22 is formed in the bottom of the body so that the device can be bolted to a bench or the like and the lower part of the body is formed with the recesses 23 having tapped 55 holes 24 therein so that legs can be fastened to the body.

Thus it will be seen that I have provided a device whereby indentures of uniform size can be formed or re-formed in the disks to insure even spaces between the disks when assembled in a separator, and means for straightening any irregularities in the body of a disk as well as to remove corrosion and rust. Thus when the disks of a separator have been restored to their original shape with this device, most of the troubles which occur in a cream separator after the same has been used for some time will be eliminated. When the disks of a cream separator become worn and out of shape, the bowl will become unbalanced and it will wobble and these defects are injurious to the rest of the machine and unsafe for the operator. The proper spacing of the disks is necessary for perfect skimming and this machine insures uniform spacing by restoring the indentures to their original shape and the proper spacing of the indentures on the disk.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What is claimed is:-

A device for re-forming indentures in cream separator disks comprising a body having an upstanding projection thereon formed with an elongated rounded upper edge, said rounded edge acting to prevent breakage or distortion of the curvature of a disk being operated upon, said projection having a circular bore extending downwardly from the central portion of said rounded edge, a spring pressed plunger in the bore, the upper end of which snugly fits in the top part of the bore, an arm carried by the body and having a vertically arranged part located above the projection, said part having a vertical bore therein in alignment with the first mentioned bore, a rod passing through the second mentioned bore and having its lower end tapered and terminating in a flat part, the lower end of the rod being threaded, a pair of nuts on said threaded end, the lower one having its lower end tapered to prevent breakage of the curvature and said lower nut limiting downward movement of the rod.
