EDWIN B. DONALDSON, OF WASHIN TON, DISTRICT OF COLUMBIA, AssieNoR or ONE-HALF TO FREDERICK A. LINGER, or WASHINGTON, DISTRICT or COLUMBIA.

AT AcmEE'IvT' r03 rnonoemrns,

To all whom it may concern:

Be it known that I, EDWIN B. DoNALDs'oN, citizen of the United States of America, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Attachments for Phonographs, of which the following is a specifiment of t cation.

This invention relates to phonographs and like instruments in which a cylindrical recordis applied to a cylinder.

An object of the invention is to provide means for imparting to the record an initial movement or thrust to disengage the record from the oylinder'and project it beyond the I end of the cylinder in order that the operator may handle the same by applying his fin ers to the internal.wall of the cylinder an obviate any damage to the said record which might result from handling the exterior surface. t

'A further object of this invention is to provide a means for connecting the record actuating device to the end gate of the ordinary PhOIIOgTQJiIhS, in order to impart the movee said end gate to the actuating mechanism; thus releasing and actuating the record at a single operation.

A still further object of the invention is to provide an attachment of the character notedthat can be applied to phonographs now in common use without in any way changing their construction; the said attachx fully set forth and described.

In describing the invention in detail, referenee will be had to the accompanying drawin s, forming part of this speclfication n whic like characters denote correspond- In parts in the several views, in which gure 1,'is a topplan view of a portion of a phonograph showing the invention applied Specification of Letters Patent. 7 Application filed March 28. 1907- Siarial No. 366.074- I Patented Feb. 25, 1908.

rear thereof. Fig. 3, is a view in elevation of the end thereof. Fig. 4, is a rear elevation showing a modified construction. Fig. 5, illustrates another modification. Fi 6, is a perspective view showing the detai s of construction of the attachment illustrated in Figs. 1 and 2. Fig. 7, is a detail view of a further modification.

In these drawings A, denotes a base of a phonograph, B, a' cylinder of ordinary construction and C, the end gate of an ordinary phonograph.

The attachment consists of a standard D, having suitable bearing E, at its end to re- 'move a rod F, which is adapted to-slide in said bearing. The standard has a suitable base or foot G, which is clamped or otherwise secured to part of av phonograph. The rear end of the rod F, has two curved arms H, their armed surfaces conforming to the contour of the surface of the cylinder, and being approximately the thickness of a record, although the proportion of the arms is an immaterial detail.

The outer end of the rod has a pivotally connected link I, extending to a oint nearly under the retaining lever. A J, is attached to the retaining lever by the hook j, embracing said retaining lever and said hook terminates in an angular extension K, to which the outer end of the link I, is pivoted. 7 I V In the modification shown in Fig. 4, a pihonograph may be provided with a bracket or if desired, the rod which usually forms a portion of the phonograph maybe utilized as a means forsuspending the hanger Y, which hanger terminates in bearings y, in which the rod W, may slide. In this form the remainder of the structure, viz: the rod,

' record engaging arms, the link and the means for securing the outer end of the link to a hook which engages the end gate of the honograph are the same as those heretofore described and need not, therefore, be referred to, in detail.

In the modification shown in Fig. 5, the

bracket V, is the same as that shown in Figs. 1, and 2, except that it is shorter and 1s stationed under the record. In this form the rod T, is slidable in bearings of the bracket and the arms'S, embrace the cyhnder from the bottom, while the link R, has a thereto. Fig. 2, is a view in elevation of the I hooked extension Q, 1 embracing the end able therein having on its ends the arms 3,

which are to contact with the record. This modification is designed for use on-phonographs not having the end gate and tor the purpose of permitting the manipulation of the said rod the outer end thereof has a right angular extension 4 forming a thumb piece, which is engaged by the hand of the operator for reciprocating the rod in its bearings.

VVhattI' claim is: v

1. An attachment for phonographs consisting of a bar adapted to reciprocate, bearings therefor, curved. arms on the end of the bar'shaped to the contour of'a cylindrical.

record and adapted to abut the end of" the record, an end gate, and means for connecting the bar tothe end; gate to take movement therefrom.

2. In an attachment iol' phonographs, abar adapted to reciprocate Wlth relationto the cylinder of a onograph, record engaging means carried y the said bar and suitable means for connecting the bar to the end gate of a phonograph whereby the said bar takes movement from the lever.

3. In an attachment for phonograph's, bar adapted to reciprocate, means for supporting the bar with relation to the record of a phonograph, record engaging members v carried by the bar adapted to contact with the inner end of the said record, means for ('onnccting the bar to the end gate of a phonograph whereby the movement of the end gate is communicated to the bar.

4.31m attachment for phonographs, having a cylindrical record, consisting of a reciprocating member, a bearing therefor, curved arms on the end of the reciprocating member adapted to conform to the contour of the record and contact the ends thereof, where- .by the endwise movement of the record is afforded. I

5. An attachment for phonographs having a cylindrical record, consisting of a reciprocating rod, 2. bearing for the rod, curved arms on .the rod ada ted to lie back of the end of thei record, an means for reciprocating the ror In testimony whereof I afiix my signature in the presence of two Witnesses, this 5th day of March, 1907 EDWIN B. DONALDSON.
