EJECTING MECHANISM FOR TYPE-SETTERS.
SPECIFICATION forming part of Letters Patent SNO. 550,554, dated November 26, 1895. Application filed Tune 19, 1.895. Serial No. 553,311. (No model.)
To all whom it may concern.-
Be it known that I, PAUL FLEMMING COX, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ejecting Mechanism for Type-Setters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.
This invention is an improvement in typesetting machines, and relates especially to the type-ejecting mechanism thereof, its object being to provide means (controlled, but not actuated, by keys) whereby upon the depression of a key the proper mechanism will be released and will eject a type, such a mechanism being desirable on account of ease, speed, and certainty in action of the machine, for 'While key-actuated ejectors require firm pressure on and full stroke of each key-lever in order to operate properly the.
key-controlled ej ecting mechanism can be so adjusted that a very slight touch on a key will suffice to release the ejecting mechanism, which then operates independently of the key. I have illustrated such a mechanism in the accompanying drawings, to which I refer by letters of reference as follows, viz:
Figure 1 is a detail sectional view of a portion of a type-reservoir, type-carrying belt, key-board, and type-ejecting mechanism embodying and illustrating my invention, showing the position of the parts before the key is depressed. Fig. 2 is a similar view showing the parts after a key has been depressed. Fig. 3 is a sectional plan view of the parts shown in Fig. l, and Fig. 4 a detail View of the friction driven cams.
The type-setting machine indicated in the drawings is substantially similar to that shown in my patents, No. 528,856, dated November 6, 1894, and No. 534,550, dated February 19, 1995, and needs no detailed description.
A is the type-reservoir; B, the carrier-belt onto which the types are ejected; E, the ej ectors guided in a slotted bar D in rear of the type-reservoir.
C designates bell-crank levers pivoted at their bends on a support c below the ejectors, the vertical arm of each lever engaging a slot in the under side of the corresponding ejector, so that the latter is reciprocated when the former is vibrated.
Each lever and' ejector is operated alike by similar means, as follows: TheA horizontal arm of the lever rests on a pin F, playing through a guide-slot in bar c and carrying on its lower end a friction-roller f, resting upon the periphery of a three-lobed ratchet-cam G, loosely mounted on a shaft H, which is continually driven (during the operation of the machine) by any suitable motor. (Not shown.) Suitable means are provided for Vcausing cams G to rotate with shaft I-I, un-
less positively stopped, and I have shown a series of friction-disks g beside the cams G, said disks having keys g engaging a longitudinal groove h in the shaft, so that they rotate therewith and will cause cams G to rotate also, unless the latter are estopped. The cams are stopped by engaging with teeth 'L' on the upper ends of bell-crank key-levers I, which are pivoted at their bends on suitable supports and carry keys I on their outer ends. The tooth t' of each lever Iis adapted to engage with a notch G' in each lobe of each cam, so that a cam will ordinarily only make one-third of a revolution at each depression of the correspondingkey-lever. Levers C-are thrown back by springs C', so as to retract the ejectors, and levers I are normally thrown into engagement with cams G by springs I2, as shown.
The operation is as follows, viz: Upon depressing a key I the corresponding cam G is momentarily released. Instantly the revolv- -ing friction-disk g causes the released cam to rotate until it is again stopped by the keylevers. causes it to lift the superimposed pin F, and the latter rocks the adjoining lever C, which moves the connected ejector and causes it to eject a type from the corresponding channel in reservoir A onto the belt B. This operation takes place in a one-third revolution of shaft H, and as the latter is driven at a moderatelyhigh speed the operation is very rapid. As a very slight movement of a key I is suffi- This one-third rotation of the cam IOO cient to release the ejecting mechanism, and
as the latter thereupon operates independently of the key, there is no danger of clogging of the type-channel by reason of a partially-ejected type, as frequently occurs with ordinary key-actuated ejectors Where the operator fails to sufficiently depress a key.
The advantages of this mechanism are so obvious that further description thereof is deemed necessary.
Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-
l. In a type setting machine, the combina- Y tion of a type-holder, mechanism for ej ectin g type therefrom, and devices adapted to normally lock said ejecting mechanism with a key and mediate mechanical connections, whereby upon the depression of a key the ejecting mechanism is released and ejects the corresponding type, substantially as and for the purpose described.
2. In a type setting machine, the combination oi' a type-holder, a type ejector, mechanism for operating said ejector, a lock for said mechanism, and a key actuated lever for disengaging the lock, substantially as and for the purpose specified.
In a type setting machine, the combination of a type-holder, a type ejector, a cam for operating said ejector, a key-lever engaging said cam and preventing its rotation, and means, whereby upon the depression of the key, said cam is caused to operate the ejector, substantially as and for the purpose set forth.
4. In a type setting machine, the combination of a type-holder, an ejector for discharging type therefrom., a rocking lever for operating said ejector, a rotatable cam for rocking said lever in one direction, a key lever for locking said cam but adapted to momentarily release it when depressed; and means for rotating said cam When released, all substantially as and for the purpose described.
5. In a type setting machine, the combination of the type-holders, aseries of type ejectors, a rocking lever for each ejector, a se.- ries of rotatable cams below the levers, the rods resting on said cams and adapted to transmit movements to the levers; a rotating shaft carrying said cams, and means for causing the cams to rotate with the shaft When released, and the key-levers for locking said cams, substantially as and for the purpose set forth.
In testimony that I claim the foregoing as my own I affix my signature in presence of two Witnesses.
