v1n all of the above views corresponding parts are represented by the same numerals of reference. V

The base -plate 1 is provided with cast brackets 2 2. Mounted between said brackets is a stationary back rod 3 and a stationar)7 guide-rod 4. The brackets are also provided with bearings for the feed-shaft 5. Mounted on a stub-shaft 5/, located in one of the brackets 2, is the main driving-pulley 6, (see Fig. 5,) to which power is applied by any suitable form of motor carried beneath the bed-plate 1. Vhen an electric motor is used, it may be controlled from a switch by a button 7. The mandrel 8 is much longer than usual and is also preferably somewhat larger in diameter, so as to take a blank of special size and of large capacity. The shaft 9 of the mandrel extends entirely through the saine and at its rear end is formed as a cone which bears in a cup formed in the end of the stub-shaft 5. (See Fig. 5.) The other end of this shaft is also coned and takes into the bearing-cup 10 on the end gate 11. to one of the brackets 2, as shown, and is formed with a depending lug 12, (see Fig. 2,) with which the friction-spring 18 engages to lock the end gate in its closed position. This makes a very simple and effective construction and does away entirely with the necessity for special latches, which have to be first operated before the gate can be opened, as heretofore. The new gate is opened by a simple swinging movement.

Projecting through an opening in the mandrel 8 is a leaf-spring`14, over which the blank is forced and which acts as a friction-latch to prevent the blank from being accidentally displaced. The blank cannot be removed from the mandrel without compressing this spring, and the friction thereby imposed on the blank will be sufficient to t'urn it in use even if the blank does not tightly engage the mandrel. This feature prevents records working loose during use and failing to receive dictated matterA before the defect is discovered.

Keyed to the mandrel-shaft 9 is a pinion '15, which meshes with and drives the gear 16 on the feed-shaft 5. The clutch member 17 is splined to said mandrel-shaft, so as to be movable longitudinally thereon. rlhis clutch member is provided with ratchet-teeth which engage corresponding teeth on the hubof the driving-pulley 6, so that when said teeth are in engagement the driving-pulley will rotate the mandrel and feed shaft, as will be This end gate is pivoted" evident. The yoke 18 engages the ehlteh member 17 and is carried by the shaft 19, working in the bearing on the bed-plate 1. At the bottom of this shaft 19 is an arm 2l), which connects by a link 21 with the arni 22 on the rock-shaft 28, mounted in the bearing 24 on the under side of the bed-plate. Secured to the other end of this rock-shaft 23 isa small walking-beam 25, whose ends are connected with linger-pieces 26, indicated with the words Stop an( LStart By pressing down on the proper linger-piece the rockshaft will be tilted, so as to swing the clutch into or out of engagement with the d rivingpulley to start or stop the mandrel. ln order that the starting and stopping device may be operated by the foot-pedal, we provide a lever 27, which may be connected at its ends with a foot-pedal (not shown) and which is adapted to be connected to the rock-shaft 23 by a thumb-screw 28. The spring 29 normally retracts the lever 27, so that when the latter is connected with the rock-shaft 223 the spring 29 will normally hold the clutch meinbers out of engagement. By depressing thel foot-pedal against the tension of the spring 29 the clutch members will he thrown into engagement, so as to drive the mandrel.

In order to properly support the mandrel when the end gate 11 is open, we extend the mand rel-shaft9 through the bearing-sleeve 30, as heretofore.

Mounted to slide longitndinallyon the back rod 8 is a frame 31, having an integral east arm 32, which extends up over the rod 4 and is provided with a roller 33, which normally bears on said rod. The frame 31 is provided with a leaf-spring 34, carrying` the feed-nut 35, engaging' the feed-shaft 5 and adjustable by means of' a thumb-screw 36. The frame 31 is also provided with an index or pointer 37, which extends over the rod 4 and cooperates with a scale thereon, as shown.

Pivoted 4to the arm 32 on a horizontal pivot is an arm 38, to which the spectacle-frame 39 is pivoted. This spectacle-frame is provided with a thumb-piece 40, by which it may he elevated and swung to one side or the other to bring the recorder or reprodncer into the proper relation with the record or blank. The arm 32 is formed at its front edge with a slot or channel 41 therein, with which ears 42 on the spectacle-frame are adapted to engage, so as to center the spectacle-frame, with the recorder or reprodncer in the proper relation. In Fig. 3 we illustrate one of the ears for the recorder in this engagement, the arm being omitted for the purpose of showing` the ears 42 and the slot 41. By elevating the spectacle-frame so as to swing the arm 38 on ils horizontal pivot the ear 42 will he elevated out of the slot 41, so as to permit the spettacle-frame to be swung out to one side and permit the other ear to engage said slot. When the spectacle-frame is thus elevated, itis liniloo' ited in its swinging movements bythe pin 43.

tliefunder surface of the forward endof the' .arm 32, as willbeunderstood, Fig. 4. 'We

also make use of an adjusting-screw 47, which `passes through the arm 38 and vengages the arm 32, so astoregulate the position of the spectacle-frame with respect. to the record or blank and secure the proper engagement of the recorder or reproducer therewith. This adjustment 1s important in' commercial machines, vsince records will be shaved many times, and hence will vary considerably in thickness.

'If these lugs were not used, there would be danger of injury to the diaphragms inr casev the device had been adjusted for use with a very thin record or blank and was then used without readjustment on a much thicker record or blank, since the adjustability of the strain.

In; the reproduction of the work for purposes of verification the speaking-'tube may be used for listening purposes, as will be understood.

rlhe arm 32 -is formed at one side with a lug 50, in which is mounted the shaft 51 of the repeating mechanism. On the lower end of this shaft 51'is a disk or head 52, which takes under the'rod 4 and prevents upward movement of the forward end of the arm 32 when the arm 38 is elevated to simultaneously disengage. the recorder or reproducer from the record-surface andv the feed-nut 35 from the feed-shaft. rIhe shaft 51 is also provided with a disk 53 thereon, which is located abovetheI rod 4. This disk 53 is formed with a cam 54 When, however, the lugs orv thereon, (see Fig. 6,) andthe lug' 50 is formed with a correspondingcam 55. Normally these cams 54 and 55 are out of line with one another; but by turning shaft 51 to one side or the other by the lever 56 the two Acams will engage together and result in the elevation of the arm 32 (see Figs. 8 and 10) to lift the spectacle-frame and feed-nut, respectively. The spring 57 is coiled around the shaft 51 be- .tween the lug 50 and the lever 56, so as to force the arm 32 downward when the lever 56 is returned to its normal position. Pivoted to the under side of the disk 53 is a springactuated pawl 58, adapted `to engage teeth 59, formed on the side of the bar 4. When the lever 56 is moved to the position lshown in Fig. 8, the cams 54 and 55 will not only elevate the arm 32 to disengage the feed-nut`l35 from the feed-screw, as well as to lift therecorder or reproducer from the record-surface, but immediately after this movement the pawl 58"will engage the teeth '59, so that at the completion of the swinging movementof the lever 56 the entire moving frame, comprising the arm 32, spectacle-frame 39, and frame 31, Will be shifted to the extent of a few threads towardl the starting position, whereupon the reproducer may be engaged with the record to verify the same. If desired", the arm 56 may be given a number of feed movements, as described, so as to carry the recorder or reproducer back to any point on the record that maybe desired. When, however, the arm 56v isv moved in the opposite direction, the cams 54 and 55 will elevate the arm 32; but the pawlv 58 will be carried away from the teeth 59, (see Fig. 10,)so as to per'- mit the parts to be moved freely back and forth, since the feed-nut 35 will be` clear of the feed-screw and the recorder or reproducer will be clear of the record-surface.

Our improved commercial phonograph is provided with a bell 60 of any suitable construction, whose clapper is adapted to been- A speaking-tube (not shown) is applied to gaged by a small gravity-pawl 61, (see Fig. 3,) carried by the frame 31. -By this' construction as the spectacle-frame moves toward the' rear end of the record-surface vthe pawl 61 will engage the bell-clapper, so as to move the latter and permit it to be subsequently released as the pawl progresses in its move- The general operation of the device has IOO already been indicated with suliicient fullness to be understood in connection with the description of its several parts, it being understood, of course, that any approved arrangement of recorder and reproducer is used in connection with the spectacle-frame.
