MACHINE FOR SETTING TYPE.

SPECIFICATION forming part of Letters Patent No. 702,458, dated June 17, 1902.

Application filed June 24. 1901- To all whom, it nuty concern/.

Be itknown that I, FRANK MCCLINTOCK, a citizen of the United States, and a resident of Mount Vernon, Westchester county, State of New York, have invented a new and useful Improvement in Machines for Setting Type, of which the following is a specification.

My invention relates to improvements in the type-ejecting mechanism of type-setting machines, and particularlyito that class of type-setting machines in which the types are contained in a series of vertical channels, from which they are successively forced out or ejected'longitudinally by suitable typeejectors adapted to engage and eject the bottom type in each channel only.

The objects of my invention are, first, to provide a power-actuated type-ejector and simple mechanism for operating the same whereby the ejector will be caused to make one complete positive movement at a definite and uniform speed upon the depression of a suitable key-lever, such key-levers and connections being so constructed that the ejecting mechanism will not repeat or'cause the ejection of more than one type if the key should be held down indefinitely; second, to provide means whereby any obstruction to the freeand complete forward movement of any type-ejector will be prevented from in-. juring either the mechanism or the type and which will furthermore prevent any further operation of any of the remaining type-ejectors until such obstruction is removed, thus immediately indicating to the operator such condition.

My invention is shown in its preferred construction in the accompanying three sheets of drawings, in which Figure 1 isa plan view from above of a portion of the frame which supports the mechanism and the type-case. Only twelve of the type-ejectors. are shown; but as many are provided as will furnish one for each of the separate compartments in the type case. Fig. 2 is a vertical sectional View on the line C D of Fig. 1, showing the parts in theirnormal position.

Fig. 3 is a sectional elevation along the line E F of Fig. 1, showing the parts Serial No. 65,738. (No model.)

in the position assumed when any obstruction prevcntsthe free and completeforward movement of atypc-ejector. Fig. 4 is a front sectional elevation on the line A B of Fig. 2, showing the series of blocks which carry the studs for retaining the pushers in gear with parts in blocks 5, both of which fit looselyin the channels 3. Eachtype-channel has openings 6 and 7 at its base on either side, the former of whichis adapted to admit the forward end of the type-ejector rod 8, while the latter al lows the lowermost'typeonly in the channel 3 to be ejected therefrom when the ejectorrod is caused to move forward. The typeejector rods 8 have theirfront ends flattened and extend through collars 9 and are fitted into guide-bearings 10, while the rear ends are secured to endblocks 11, which are fitted to slide freely in guide slots .12. A coilspring 13 serves to retain the type-ejector rod Sin its retracted normal position (shown in Fig. 2) and to return it and the pusherbar 15 to this position after being advanced, as will be hereinafter described. Stops 14, which are preferably cushioned with leather pads 23, limit the forwardmovement of the ejector-rods 8 and the pusher-bars 15, while the return movement is limited by the lugs 16 on'the lower face of the pusher-bars 15 engaging a cushioned stop 17, secured to the rear end of the cradle 1.

The pusher-bars 15 are provided with a series of ratchet-teeth 18 on their upperedges,

which are of the same pitch as theratchetteeth on the roller19. The front endsof the pusher-bars 15 normally rest upon the free ends of the levers 20, which are adapted to raise the front ends of the pusher-bars 15 a sufficient distance to causethe engagement of the ratchet-teeth 18 with the ratchet-teeth on the roller 19. These levers are fulcrumed at the point 21 to a-longitudinal rod 22, extending across the cradle. Cords or wires 24 are attached to the projecting end 25 of each such normal position after having been depressed by the operator, as shownin Fig. 3. The tension of the springs 27 may be adjusted as desired by means of the screws 29.

For the purpose of causing the required forward movement of the pusher-bars a ratchet-toothed roller 19 is provided, which is fitted in suitable bearings 30 on the cradle 1 and is actuatedlby means of a driving-belt 32, running on a driving-pulley 31. The driving-pulley 31 is fitted looselyon the projecting end 33 of the ratchet-roller 19, being provided with some suitable friction device the tension of which will be sufficient to cause the pulley 31 to drive the ratchet-roller 19 positively under normal conditions, but yet in the event of any obstruction to the rotation of the ratchet-roller to be sufficiently loose to permit the revolution of the pulley to continue without injury or undue strain to the mechanism. The friction device shown consists of a four-armed spring-spider 34, which is rigidly secured to the ratchet-roller shaft 33. The nuts 35, coming in contact with a fiber washer 36, serve to hold the pulley 31 against the arms of the spring-spider 34. The tension of the friction device may be adjusted at will by screwing the nuts 35 in or out.

Fig. 2 of the pusher-bar 15.

In order to positively retain each of the pusher-bars 15 in gear with the ratchet-roller 19 until it has accomplished its complete forward movement and has caused the ejection of a type from the appropriate channel, laterally-projecting shoulders or flanges 40 are provided on the sides of the pusher-bars 15, which are adapted to pass freely through the openings 41 above the projecting studs 42 in the guide-blocks 43 when the front ends of the pusher-bars have been raised to the operative position shown in Fig. 3. The guideblocks 43 are preferably made independent of each other and are attached singly to the rib 44 on the hinged plate 45 by means of the screws 46. This allows any one block to be readily removed if worn or broken and reerator puts his finger upon the key of the lever 26, thus throwing down the end 25 of the lever 20 and raising the right-hand end in The teeth upon the upper edge of the pusher-bar 15 engage with the teeth upon the constantly-rotating ratchet-tooth roller 19, whereupon the pusherbar 15 begins to move forward. As --this takes place the laterally-projecting shoulder or flange 40 passes over the projecting stud 42, thus releasing the pusher-bar from the lever mechanism and holding the teeth in contact with those upon the roller 19. \Vhen the end of the line of travel is reached, the flange 40 has passed over the projecting stud 42, and thereupon the end of the pusher-bar will be free to drop and will assume its origi-- nal position, resting upon the end of the lever 20. If the key-lever 26 and the short lever 20 for any reason remain depressed, the shoulder 40 on the pusher-bar will engage with the upper corner of the front end of the lever 20 and be thereby prevented from being forced entirely back to its position ready to be again actuated until such time as the key-lever 26 be released, thereby preventing the possibility of two or more actuations or repeating of the pusher-bar 15 for one depression of the key-lever, which has usually been a disadvantage with mechanically-actuated type-ejecting devices.

In the event of any obstruction which provents the type-ejector rod 8 and pusher-bar 15 from completingtheir forward movement,

"as shown, for example, in Fig. 3, where the types having been all ejected from the typechannel 3 the follower-block 5 rests at the bottom of the type-channel, and thereby blocks the forward movement of the typeejector rod 8 and pusher-bar 15, the ratchetteeth 18 on the pusher-bars being in engagement with the teeth on the ratchet-roller 19 it must stop revolving; but the frictional connection between said roller and its drivingpulley 31 will allow it to continue without undue strain on the mechanism. ,The ratchet roller 19 being thus stationary, it will be impossible to operate any of the other type-ejectors, which will at once call the attention of the operator to the fact that the type-channel is empty.

The locked pusher-bar may readily be thrown out of engagement with the ratchetroller by the depression by the operator of a key-lever 50, which is connected by the cord or wire 51 to the pin 52 on the side of the hinged plate 45, provided with a vertical ranged to eject the lowest type from the typecase; a sliding rod provided with ratchetteeth arranged to engage with the ratchet wheeland to intermittently advance the typeejector; a lever actuated by a key-lever for effecting connection between the type-ejecttypes are ejected; a type-ejecting rod arranged to eject the lowest type from the type case; a sliding rod provided with ratchetteeth arrangedto be temporarily broughtinto engagement with the ratchet wheel and adapted to advance the type-ejector; devices, substantially as described, for holding the rod in engagement until the ejector has ejected a type; means for automatically releasing the type-ejector after the same has been advanced; a lever actuated by a key-lever for efi'ecting the connection between the rod and the ratchet-wheel; and spring devices for retracting the type-ejector to its original position.
