'1 claims. w1. zii- 10) This invention relates to means for transferring sound record disks from a supply magazine to a phonograph turn-table and for removing the record disks from the tum-table. More particularly, the present invention is concerned with the suction head of the record-disk transferring means forming a part of my application for Machines for recording and dispensing phonograph records, Serial Number 372,532, filed December 31, 1940, andthe present application is a con-i l0 tinuation-in-part of my said prior application. fIn accordance with the present invention and pursuant to one of the objects'thereof, the suction head comprises means for preventing the with the central opening ofthe record disk and to provide an airtight joint between the suction head and the record-disk along a peripheral line spaced radially outwardly from the-central hole 'communication -of the interior of suction head 15 of the record-disk and radially outwardly beyond l the area of .the upper disk surface to which suction is applied.

Another object of the invention is to provide a suction head provided with means for forming a suction chamber at the top of the record disk between the latter and the suction head. Another object of the invention is generally to provide a suction head of improved construcor from a support therefor.

The above and other objects, features and advantages of the invention will he fully understood tion and operation for moving record-disks to 3 from the following description, referencev being had to the accompanying illustrative drawings. In the drawings:

Fig. 1 is a sectional view on the line I-I of Fig. 2, the suction head being shown in full lines in position over the turn-table and in dotted lines in position over the record-disk supply magazine, parts being omitted for the sake of clearness of illustration;

tion-head in engagement with the record vdisk; Fig. 5 is. a bottom plan view of the suction head.

Refening now to the drawings in detail. the

suction head I0 forming a part of theV record disk transferring means is mounted on the suction-head carrier I2 and is movable by the latter to and from .the positions illustrated in full lines and in dotted lines in Fig. l1 for moving the recordldisks R, one at a time, from the supply magazine M to the phonograph turn-table T and from' the latter to an intermediate position over A a delivery chute Q, the lower end of which com-- municates with a delivery opening in the front of the cabinet as illustrated in my abovementioned prior application. I

As will be presently described, the suctionhead carrier I2 is mounted for oscillation about a vertical axis whereby to position the suction head above the record disks in the supply magazine and to move the topmost record to a position on the turn-table andv thereafter to move the record from the turn-table to a position over the discharge chute C. Also, as will be presently described, the suction head is mounted for vertical movement in relation to the suction-head` carrier I2 for engaging the topmost record in the supply magazine and for lifting said record fmm the records therebelow in themagazine, for low- `ering the transferred record to its. position on the turn-table, and for raising the record from theturn-table preliminary to the removal of the record therefrom to the discharge chute. The means for oscillating the suction-head carrier and-for raising and lowering the suction head on the carrier are preferably the same as clis-` closed in my prior application and will, therefore, not be described herein except to the extent necessary to the explanation of the operation of the suction head as deiined by .the claims in 'this application. i

The suction-head carrier I2 is a. hollow tubular member having a horizontal part I4 and vertical parts I6 Vand I8 at the opposite ends thereof, respectively. Said suction-head carrier I2 is iixed to the upper end of a hollow vertical` shaft 20 which passes through vertical end part I6 of carrier I2. An upper end portion 22 of shaft 20 is enlarged to provide a shoulder 24 by which shaft 20 is supported in vertical position on a stationary frame part 26 and for providing a shoulder 28 which is engaged by the confronting surface o'f the internal boss 30 formed in end portion I6 oi carrier I2. The upper reduced end portion 32 of shaft 20 above shoulder 28 projects yupwardly through said boss 30 and is engaged by member I2 with an interposed lock washer 36. Shaft 28 is journalled for turning movement in a bearing bushing 38 provided in frame part 26 and in a bearingbushing 48 mounted in a stationary frame part 4 2. The lower end of shaft 20 is provided with a gear 44 which is engaged by a companion gear member (not shown) actuated as described in my above mentioned application for oscillating shaft 28 about its vertical axis. The lower end of part I6 of carrier I2 communicates with a chamber 46 in frame part 28, said chamber having an opening 48 which communicates with a source of suction as described in my prior application.

The suction head I8 comprises a cylindrical tubular member 58 having an upper portion 52 which has a slidable and rotatable fluid-tight t with the inner cylindrical surface 54 of the lower end portion 56 of the end part I8 oi carrier I2. Said tubular part 58 of the suction head communicates with the interior of carrier member I2 through a plurality of openings 58, the interior of member I2 being in communication with the source of suction through chamber 46. Above said openings 8, member 58 ofthe suction head is provided with an integral cylindrical portion 68 which has a slidable and rotatable fluid-tight llt in an opening 62 in the top of end part I8. The vertical movement of suction head I8 is provided for by the mechanism which includes the lever 64.pivotally mounted between its ends on a pinv 66 carriedby brackets 68 at the top of carrier I2. The upper enlarged en d portion 18 of the cylindrical stem 1I of suction head is engagedby the forked end 12 of one arm of lever 64. The other arm of the lever is engaged at its end by a sleeve 14 in which theend of a cable 16, such as a wire or cord, is fixed. Said cable 16 extends longitudinally through hollow shaft 28 to a point below the lower end of said shaft where said cord is engaged by the mechanism described in my prior application for moving said cable downwardly andfor permitting said cable to move upwardly in timed relation to the actua-4 tion of shaft 28. It will be understood that when cable 16 is moved downwardly, lever 64 is operated for raising the suction head and that when said cable .is allowed to move upwardly the suction head can move downwardly under its weight. A spring 18 secured to the top of carrier member I2 and bearing on lever 64 assists vthe downward movement of the suction head and resiliently opposes the upward movement thereof. Suction head I8 is provided with a flange 88 which is engageable with the lower end portion 56 of carrier member I2 for limiting the upward movement of the suction head.

Suction head I8 is provided with a pick-up plate 82 which is engageable with and disengageable from the record disk for moving the latter from the magazine and to the turn-table and from the turn-table to the discharge chute. The

pick-up plate 82 comprises a disk 84 provided with a central upwardly projecting cylindrical portion 86 which is screw-threaded externally thereof and is threaded into the companion lower end of tubular member 58 of the suction head whereby the pick-up plate 82 is removably secured to said member 58 in fluid-tight relation therewith. The lower surface of disk 84 is provided with a circular recess sa in which is adhesively or otherwise secured the circular gasket or packing ring 98. Said packing ring 98 is preferably resilient and may be formed of cork, soft rubber or any other suitable packing material.

Pick-up plate l82 is provided with means for sealing the central opening O of the record disk from communication with the interior of the suction head. Said sealing means comprises a soft rubber or other resilient gasket or packing ring 92, the lower end. of which engages the upper surface of the record disk near and completely around the central opening O of said disk. As illustrated in Fig. 4,

packing rings

98 and 92 when 1 engaged with the upper surface of the record disk R. definel a suction kchamber 94 above the record-disk between the outer peripheral edge of packing 92 of the inner peripheral edge of packing 98 completely therearound, and said packing rings prevent loss of suction which might otherwise occur either through central opening O of the record-disk or through any space which might be present between the lower surface of plate 64 and the upper surface of the record-disk,

if said plate were in direct contact with said record in the absence of the packing ring 90.

Gasket 92 is mounted for movement in pickup plate 82 axially thereof. For this purpose,

said packing 92 is carried by a member 96 which is provided with a central vertical extending recess 98 for receivingthe centering pin 99 oi the turn-table or the upper end'portion of the centering rod I88 of the supply magazine when the suction-head is positioned over the turn-table and supply magazine, respectively, in engagement wardly 4thereof and connected thereto by the spider portions |86 providing openings |88 in the pick-up plate to provide communication between the exterior of the pick-up plate and the interiorv of the suction head. The packing carrying mem` 9. ber 96 is provided with an upper stem I I8 which projectsthrough an opening II2 in hub part |84. A pin I I4 passing through the outer end of stem II8 limits the downward movement of member 96. A spring II6 bearing at one end thereof against member 96 and lat its other end against the top of hub part |84, presses member 96 and the packing 92 carried thereby downwardly for` resilient engagement with the record disk. The

parts of pick-up plate 82 are so dimensioned that packing member 92 is projected by spring II6 to apoint below the outer surface of packing ring 98 so that said packing ring member 96 is in a, position to engage the upper surface of the record-disk in the magazine before said surface is engaged by gasket 90 while the suction-head is descending for engaging the record-disk. During the descent of the suction-head from a position above the record-disk to a position in which the pick-up plate engages xsaid disk, the lower edge of packing ring 92 is engaged by the record-disk and moves upwardly with member 96 in hub part |84 against the resilient pressure of spring II6 and packing ring 98 engages the upper surface of said record-disk. The upward movement of member 96 in hub part |84 is limited by a shoulder II8 of hub member |84.

In order to xedly secure packing ring 92 to member 96 in such manner as to prevent movement thereof. longitudinally of said member, the

outer surface portion I28 of member 96 is tapered upwardly. It will be observed that as shown in Fig. 4, the packing member 92 extends downwardly below the lower end of member 96 to provide said packing member withel lower resilient end portion whichis not interfered with by the assaieo f carrying member 96. The flange |22 prevents movement of gasket 92 upwardly on member 96. The outer surface of gasket 92 is preferably cylindrlcal in parallel relation to the adjacent inner cylindrical surface of hub member |04.

It will be understood that after the recorddisk is moved from Athe supply magazine and placed on the turn-table T, the suction-head remains in engagement with the upper surface of the record and rotates therewith during the rotation of the record by the turn-table, the weight suction head is raised to lift the record from the turn-table and then the carrier is turned to position the record over the discharge chute C.

chute to the discharge opening of the cabinet shown in my prior application.
