EXIANDER AND FLANGER.
Specicatonof Letters Patent.
Patented Aug. 3, 1909.
Application ile'd December 26,1908. Serial No. 469,279.
To all whom it may concern:
Be it known that we, FRANK PFLUGER and EMlL CHRIs'rENsEN, citizens of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Expander and Flanger, of which the following is a speciiication.A
This inventibnrelates 'to improvements in tails, to be hereinafter described and claimed.
In the accompanying drawings z-Figure lv is an elevation of the invention, partly in section. Fig. 2 isa planview.
Referring, more particularly, to the drawings, 5 denotes the stock of the implement,- having, intermediate its ends, a threaded portion 6, on which a feed-wheel 7 is mounted, the bore of the latter being screw-threaded for this purpose. The feedwheel is formed withdepending ears 8, having perforations for the axles 9 of the 'thrust rollers 10.
At the lower end of the stock is a head or enlargement 11., provided with a slot, in which is ivotally mounted on a pin 13, the axle 121i o? the eX andin rollers 15, said aXle having at its en s s ind es 16, on which said rollers are mounte The headis recessed on one side, as indicated at 17, to receive one of the rollers 15, when the implement is being placed in operative position within the bushing. The axle 14, as in our former patent hereinbefore referred to, is swung by means of a lever 18 connected thereto, andV lying in a longitudinal groovel or channel 19, made in the stock 5, the free end of the lever being laterally presented to form a handle 2,05 The hereindescribed method of mountv fing. the Hanging rollers is practically the same as in our former patent. I
The upper end of the stock 5 has a squared portion 21, so that it may be fitted into a socket of an operating member. Adjacent to the u per end of the threaded portion 6, the stoc is fitted with a set screw 22, to
limit the upward travel of the feed-wheel 7. The rim of the feed-wheel is.formed with corrugations 23, in ordel'iliat a better hold may be had.
The operation ol' the implement herein described is the same as the one shown in our former patent 11,310,431, it being inserted into the bushing by swinging, through the lever 1S, the axle 14 on its pivot, so as to bring one of the rollers 15 into the recess` 17.
The implement is thon inserted into the bushing, alter which the axle is swung back to bring the rollers into operative position. The feed-wheel 7 is now turned until the thrust rollers 10 are in contact with the outer end of the bushing, and the flanging rollers 15, with the inner end thereof. The stock 5 is then rotated, the feed-wheel being simultaneously o erated to force the rollers closer together, w iereby the inner end of thc bushing.is expanded. and formed into4 an outwardly disposed flange, which/engages with the inner surface of the keg, adjacent to the bunghole, and holds the bushing securely therein. Il desired, the stock may be held stationary, and the barrel rotated.
By mounting the thrust rollers directly on the feed-wheel, they will continually change their position with respect to the Hanging rollers, which results ina smoother job, and give a certain flexibility, which is much desired, and, besides, enables the implement to be more strongly constructed. The thrust rollers are truste-conical, by reason of which they will lay down the flange closer to the keg.
What is claimed isz- A Hanging implement comprising a `stock having a. threaded portion, Hanging rollers carriedrat one end of the stock, a feed Wheel rotatably mounted on the threaded ortion of the stock, and thrust rollers carrie by the feed wheel, and movable therewith, whereby the position of the thrust rollers with respect to the Hanging rollers caused to continually change as the feedwheel is operated.
' In testimony that we claim the foregoing as our own, we have hereto affixed oursignatures in the presence ol two witnesses.
