IMPROVEMENT IN FLUTlNG-MACH INES.

Specification forming part of Letters Patent No. 222,679, dated December 16, 1879; application filed October 20, 1879. 1

To all whom it may concern:

Be it known that I, JOHN E. DONOVAN, of Cincinnati, in the county of Hamilton, and in the State of Ohio, have invented certain new and useful Improvements in Fluting-Machines and. I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which Figure l is a perspective view from the front of my improved device as arranged for use. Fig. 2 is an elevation of the rear side of the same. Fig. 3 is a like view of said device with the upper roller in position for removal.

'Figs. 4 and 5 are elevations of the rear end,

and show, respectively, the arral'igement of parts shown in Figs. 2 and 3; and Fig. 6 is a perspective view of the parts composing the socket of the ball-bearing of the clamp, said parts being separated from each other.

Letters of like name and kind refer to like parts in each of the figures.

The design of my invention is to increase the efficiency and to lessen the expense of fluting-machines; to which end it consists, principally, in a tinting-machine having formed between its base and standard a socket for the reception of a ball,.which forms the pivotal end of its fastening-clamp, substantially as and for the purpose hereinafter specified.

It consists, further, in the means employed for securing the fluting-rollers within their bearings, substantially as hereinafter shown.

In the annexed drawings, A represents the base of my machine, provided at its center with an opening, a, which is preferably polygonal in shape, and at its lower side is spanned by a bane, that is cast with and forms part of said base.

Within the opening a is placed the correspondingly-shaped end I) of a hollow standard,

'13, which is secured in positionby means of bolts that pass through the bar a, and through suitable lugs that are provided upon the inside of said standard.

The standard B has the form shown in Fig. 2, and is formed in two pieces, that are united upon a central vertical line, while from the upper end of one of said parts an arm, 0, extends horizontally outward'to or near one end of the base A, and thence downward, and then inward, and at its end terminates in a cylindrical boss, 0. The lower portions of the standard B are held together by the bolts employed for con meeting the same with the base A, while the upper portions are united by means of a screw, D, that passes through one part, and has its threaded end contained within a correspondin gly-threaded opening in the second part.

Within the upper portion of the standard B is provided a vertical slot, I), that corresponds in horizontal dimensions to the diameters of the journals 6 of two corrugated rollers, E, the upper end of said slot being formed upon a circular line, and having such length above 7 the screw D as to enable one of said journals to be contained within such portion.

The outer end of the upper roller E passes over the boss 0 of the arm 0, which thus forms a bearing therefor, and is held in position thereon by means of a lug or shoulder, c, that is formed upon said arm and bears against the rear end of said roller, as seen in Fig. 2.

The lower roller E is supported within a frame, F, which rests upon a rod, Gr, that passes vertically downward into the standard B at its axial center, and is made vertically adjustable therein. The outer portion of said frame is the same in form, only reversed, as the like portion of the arm G, and its inner end is provided with a bearing (shown in dotted lines in Fig. 2) for the reception of the inner journal, e, of the lower roller E, the outer end of the latter being supported upon or by a boss, fi j A lug, f, similar to the lug c, is provided upon the inner portion of the frame F, and, en gaging with the inner end of the lower roller E, holds said roller in place upon the bossf.

To remove the rollers E it is only necessary to withdraw the screw D and permit the up per roller at its rear end to drop downward out of engagement with the lug c, after which said roller may be moved longitudinally rearward until free from the boss 0, then laterally until its outer end is clear from the arm 0,

PA'rEN'r .Qr'r'ron.

contained within a socket, X, which is formed partly within the base A and in part within the standard B. Said ball-bearing his inserted within its socket before said standard and base are drawn closely together; but after said parts are in place said ball is prevented frombeing withdrawn, while free to rotate upon itsaxist The clamp thus connected with the. machine is entirely free to. adjust itself to any desired position, either for use or storage, and. await cannot bedetached without breakage, itisnot liable to become lost.

The means employed for forming the socket X render unnecessary special fitting of the same or of said ball, nothing being required except to clean the castings in the usual manner before fitting said parts together.

Having thus fully set forth the nature and merits of my invention, what I claim as new 1. A fluting-machine having formed between its base and standard a socket for the reception of a ball, which forms the pivotal end of its fastening-clamp, substantially as and for 1 the purpose specified. ner end it is provided with a ball, k, that is Z 2,. In combination with the bosses c and f,

which furnish bearings for the outer ends of the rollers E, the lugs c and f, provided'upon the arm 0 and frame. F, respectively, and the screw D, passing through the: sections of the standard 13, substantially as and forth'e purpose. shown.

In testimony that I claim the foregoii-ig l have hereunto set my hand this 17th day of October, 187 9..
