TYPE'SETTING MACHENE.

Specification of Letters Patent.

Patented Nov. 27, 1h06.

To all whom t muy conclu-11,:

Be 1t known that I, FRANK MCCLINTOCK, of Mount Vernon, county of l tchester, and

IState of New York, have invented a new and useful Improvementin Type-Setting Machines, of which the following is a specification.

My invention is an improvement in typeejecting mechanism heretofore invented by Ine and shown in United States Patent No. 702,458, issued June 17, 1902.

The objects of this invention are to provide means whereby the ratchet-teeth on the type-ej ector bars will be more promptly direngaged from the teeth of the actuating roll or shaft and prevented from being accidentally thrown again into gear with the ratchetteeth of the rotating shaft and also to siniplify and reduce the cost of the manufacturing and assembling of the parts` The invention is shown in the accompanyfl ing drawings.

Figure 1 is a sectional perspective view showing the parts in their normal position when not in operation. Fifa 2 is a similar view showing oncof the lreyllevers depressed and the corresponding type-ejector bar in action.

Similar reference characters refer to similar parts in each of the views.

Iii the drawings, 1 is the bed-plate of the machine.

2 is the ty e-case, which has plurality of type-charme s 3, each channel containing type 4 of one kind only. Each type-channel is provided with an opening 5 in 'its front of suitable width to allow of only a single type being ejected therefrom and anoiher opening 6 in the rear through which the forward end 7 of the type-ejector may enter.

l() represents the type-ejector bars, which have ratchet-teeth 13 near their rear ends and are provided with a latcrn.lly-'projecting lip l2. The type-ejectors 7 are screwed into theI front end of the ejector-bars l() at the point 9. y

15 is a pivoted plate to which the campi ics H are secured. By depressing tlfif; plate al'. of the acting ejector-bars may be thrown ont ot action, and thus the delivery of type rrcsted.

The type-ejector bars are retained in their proper position parallel lo each other and guided longitudinally by means of two bearings S and 15 is the ratchet-toothed roll, which is caused to rotate continuiiusly by any convenient power.

.6 represents the rods whereby the rear ends of type-cjector bars are elevated to bring the ratohehteeth 13 into gear with the ratchet-teeth on the roller 15u. lhe rods 1G are actuated by means ol' a key-lever 24, having a suitable finger-button Upon the depression of the `lingerdrey 25 the rod 16 is elevated, as shown in Fig.y 2, which raises the rear end of the ejector-bar 10, thereby causing the ratchczt-teeth 13 to become engaged by the ratchotetceth on the rapidly'- rotating roller 15a, which thereupon forces the ejector-bar forward, and the flat end 7 enters the type-channel and engages with the lowest type in the channel 3 and eject-s it therefrom through the opening 5 in the usual manner, As soon as the ejector-bar Vl() begins to move forward the lip 12 engages with the cani-piece 14, thereby preventing the said riliector-bar from dropping down andthus becoming disengaged from. the ratchet roller 15ZL until it is moved forward the rcu quired distance'to force the type entirely out of the type-channel.

It is very desirable that the weight of the ejector-bars bc kept as light as possible, and it has been found in V)raclfice that the 'weight of the cjectonhars alone is generally insullicient to insure 'the required quick dropping of the rear end of the ejector-bar 1i), particularly when a considerable number' ol type are contained in the channel. The ejector-bar has also been 'found heretofore to rebound upon rem-hing its.norrnal retracted position in such a manner as to throw-it again in gear, thus causing the ejection ofa second *f we.

.ln the present invention l have overcome these'defects by an improvement in the pianner of securing the springs whereby the. ejec tor-bars are returned to their normal position. A close coil-spring 22 has one end secured to a stud 17 on the iixed cross-bar 23, and the forward ond is secured to the upper end of a pin 2l, which is attached to thc typeejccting har 10. lt is to be observed that the spring acts on the pin, :forininga 'part of the ejector-bar at a point substantially above the latter and above the guide for the front end sis IOO

of the bar. n other words, the spring nete on the brrr at e point substantially out of line with the teeth :ind the guide at the iront oi the bar, so that it hns n constant tendency to throw the rear end oi the bnr downward. l t will he evident that the pull ol' the spring o n the upper end of the pin 21, will canse the ejector-bnr to drop more quickly than heretolore and will prevent any tenijlenoy of the rear end rebounding into geur when it strikes the stop 1.8. "lhe use ol. the spring in this nninnir thus allows the type-eieeto'r har 1U to he lnmde very inueh lighter 1n weight, marking the entire operation of' the ineehzini'bin inueh easier end quieter. .lt is to he noted that the Spring Applied in the deserihed relirtion to the hnr serves; three purposee: first, that of retrnrfting the hair endwise when it is disengaged 'from the roll 15"z seeond, that of insuring the disenfenigelnent of the har :rnd quiekening i:rl downward movement 'when the lip l2 puber ward oi' the enin H; third, that o" holding the lmr down no that there will he no danger oi' its rebounding und necidenta-lly rengaging the roll.

VVhnt l. elaini :is niy i mention isM l. In n type-ejeeting nfeelinninni, the corn-u hinntion of a eontinuonely-rotzrting toothed roll, a type-rejecting bnr 'hnvinY teeth to en gage the roll, u ringer-key und conneetione` therefrom to throw the bnr into engagement with the roll, means for retaining the parte; in engagement until the ejector has advanced the required distance, and a spring connection for throwing vthe ejector out of engagenient and returning it toits initial position,

Vin testimony whereof I hereunto set my hnnd, this 25th day of July, 3905, in the presenee of two attesting witnesses.
