TNZ whom it may concern:

Be it known that I, FREDRICH J. Room, a citizen of the United States, residin at Chicago, in the county of Cook and tate 6 of Illinois, have invented certain new and useful Im rovements in Ex anders for Metal Bar e Heads, of which t e following is. a specification. t

This invention relates to expanders for metal barrel heads, and one of the objects of the invention is to provide an improved device of this character by means of the use of which metal-barrel heads may be efliciently and expeditiously expanded 'for securing them in position on barrels, and in a single operation.

A further object is'to provide an improved portable hand device adapted to,be I actuated by fluidpressure. A further object is to provide an improved device of this character which will be of asimple'and comparatively light con:

struction and eflective and eflicient in opera tion. 26.

jects as will appear, the invention consists in the features of novelty in substantially the construction, combination, and arrange- 'ment of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this invention and in which;

Figure 1 is a view partly in elevation, partly in section and partly broken away of a device of this character constructed in accordance with the principles of this invention. Figure2 is an enlarged detail sectional view of the controlling valve and ports.

Figure'3 is a view partly in elevation and partly in section of a portion of the expand er showing the parts in a different position than the position they occupy in Figurel. Figure 4 is a sectional view taken on line 44 Figure -1 and Figure 3.

Referring more particularly to the drawings the numeral 10 designates a cylinder of any desired size and configuration and within which cylinder a piston 11 is reciprocable.

Connectedwith the piston 11 is a piston rod ,12 which extends through one end of the cylinder to project therebeyond and a To theattainment of these ends and the accomplishment of other new and useful obsuitable packing 13 is provided to form a fluid tight joint between the piston rod and the end of the cylinder.

Connected with the cylinder and disposed I therebelow is a suitable support 14, and the cylinder is Isu ported thereby in any desired or suita le manner, referably by means of upright bars or rods 15; suitably connected with the respective parts. 7

Arranged below the support 14 so as to slide thereagainst, are a plurality of expander members 16, any number of which may be provided, preferably four and they are preferably of a segmental configuration.

Individual to "'and connected with the members 16 are ears or uprights 17 which extend through suitable slots 18 in the support 14, the slots being ofsuch a length that the reciprocation or move ent of the members 16 with respect to the support 14 will not be interfered with. These ears. project beyond the support 14 and are provided with flanges 17* which engage and are movable upon the face of the support 14 and serve to assist in maintaining the members 16 against displacement with respect to the said support.

Link members 19 are pivotally connected by one end as. at 20 respectively with the ears or projection 17. These links may be of any desired length and are also res ectively pivotallv connected as at 21, wit a collar 22, which collar is connected with the piston rod 12 for reciprocation therewith. With this construction it will be manifest that when the piston rod 12 is reciprocated; carrying with it the collar 22, theexpander members v16 will be moved with respect to the support 14-and'toward and away from each other in directions transverse to the di- 10 preferably through one end thereof and on one side of the piston 11, is a fluid conductor pipe22. Communicating w1th the cylinder 10 on theopposite side of the piston 11, such as by means of a passage 23 in the end 'of the cylinder; is a fluid conductor pipe 24. These

pipes

22 and 24 have communication with a valve casing 251 the can ing itself having an opening 26 which has -The valve casing is also provided with a port or passage 27 with which the pipe 22 has communication, and the valve casing is" also provided with a port 28 with which the pipe 24 has communication, there being also provided an exhaust port 29 in the valve casing 25; i

A valve is rotatable in the valve casing and is provided with

passages

31, 32 which are adapted, when the valve is properly ro-. tated, to establish communication from the supply opening 26 with the

openings

27, 28 to the cylinder on opposite sides of the piston. The valve 30 is also adapted through the ports 31 and 32', to connect the

passages

27, 28 respectively with the supply opening 26 or the exhaust opening-29. The passages in the valve casing 25 and in the valve 30 are so arranged that proper connection may be established between the

openings

27 and 28 and the exhaust open- 'Anysultable means may be provided for actuating the valve 30. To that end a handie 33 which is connected with the cylinder 10 for transporting the latter, may be used for that purpose. The handle 33 is rotatably mounted with respect to the cylinder 10. A

.stem 34 is connected with the valve'30 and is also connected-with the handle 33 for rotation therewith, with the result that when the handle 33 is rotated about its axi with respect to the cylinder 10, the valve 30 will be correspondingly rotated.

In use, a metal end 35 is placed upon the barrel end 36, the end 35 being preferably providedwith a flange 37 engaging over the edge of the barrel for supporting the end.

After the end has been placed in position on the barrel, the expander is placed in position so that the members 16 will contact with the face of the end 35. The valve 30 is then positioned so as to admit fluid into the cylinder 10 above the piston 11, and to connect the opening 23 in the end oii the cylinder on the opposite side of the-piston with the exhaust opening 29. Fluid then entering the cylinder on the upper side of the piston will force the piston downwardly or toward the opposite end of the cylinder. This will lower the collar 22 and through the medum of the links 19,, the expander members 16 will be moved so that the peripheral edges 38 of the members 16 will 'force a portion of the metal 35 into the chine 39 of the barrel, thereby expanding a portion of the end and. securing the end to the barrel, as

shown in Figure 3.

. The handle 33 is then rotated to position the valve 30 so that connection will be established between the lower end of the cylinder 10 through the port or passage 28 and the The pressure on the lower face of the piston will cause the piston to rise in the cylinder 10, and this will retract the expander members 16 from the position shown in Figure 3 to the position shown in Figure 1.

When the barrel is arranged uprightly it will be manifest that the expanding tool may be placed in position upon the end 35 to be supported thereby. I

With this improved construction it will be manifest that there is provded a simple and efficient device for quickly and efliciently expanding a metal end and securing the same in position.

- It will also be manifest that there is provided a compact device which will be easy to manipulate and which will be easy to handle.

has been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims without departing from the spirit of this invention. a
