UNITED STATES PATENT OFFICE- WILLIAM J'. POOLE, OF LOS ANGELES, CALIFORNIA, ASS IGNOR TO AMERICAN LINED- GRAPH COMPANY, 015 LOS ANGELES, CALIFORNIA, A CORPORATION OF CALIFORNIA.

TYPE-EJECTOR FOR TYPE-SETTING MACHINES.

Be it known that I, WILLIAM J. PooLE. a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in Type-Ejectors for Type- Setting Machines, of which the following is a specification. V

This invention relates to an improved means of ejecting or transmitting type from the type magazine to the transfer or delivery chute of a type setting machine; specifically this invention relates to improvements in type setting machines of the generalcharacter shown in my Patent No. 1,032,564 for type composing machines issued July 16th, 1912.

The prime object of my present invention is to provide means whereby a type may be transmitted or ejected from the delivery end of the magazine into the transfer chute or equivalent in such manner and with such speed that the succeeding type cannot in terfere with the delivered type. In a device of the character described in my said patent there is a liability for the type to interfere and clog in the delivery chute when type are released in quick succession from the various magazines. The delivery chutes are all brought to a common chute; and it is here that clogging by interference between type takes place. In order to obviate this interference and to provide for release of type in quick succession, it is necessary that there be a certain minimum distance between type coming to the common chute. My present invention provides for this spacing of successive type by the means of giving the type such a velocity that one type will have traveled a certain minimum distance when a successive type is released.

In a typical embodiment of my invention I use a sloping magazine down which the types gravitationally move to a point at the upper end of the transfer chutes, there being a magazine channel for each of the chutes. The chutes are preferably vertical and the magazines preferably deliver the types in horizontal movement to the upper ends of the chutes; and the delivered type is held in the upper end of the chute wholly within the chute and entirely free from the magazine. The weight of the body of type in the magazine tends to hold the single "delivered type against a means which keeps Specification of Letters Patent.

the type from falling down the transfer chute. Said means is preferably of a yielding character; although it may be of any initial impulse along the transfer chute by any eflicient means; I have shown electromagnetic means to give the type a quick downward impulse, freeing it from the holdmg means and from engagement and interference with the following type. The following type has only to move into the position occupied by the preceding type in order to be ready for delivery to the-chute. This movement is only equal tothe thickness of the type body and may consequently take place very quickly. In fact, the next type assumes its proper position more quickly than an operator can successively manipulate a key to cause successive operations of the same impulse magnet; the speed of setting type is limited only by the manual speed of the operator manipulating the keys.

I have shown a preferred form and embodiment of my invention in the accompanying drawings, in which,

Figure l is a vertical longitudinal section showing the essential features of my invention, Fig. 2 is a front elevation of the same, Fig. 3 is a detailed perspective showing the types as they are delivered from the magazine and showing the preferred means for holding a single type at the upper end of the' transfer chute. i

In the drawings the numeral 10 may designate a type holding magazine composed essentially of a plurality of inclined bars 12 with spaces-13 between them, the spaces 13 forming the channels through which the types 14 pass. The lower ends of bars 12 are curved as at 15, so that the types are delivered'practically in a horizontal direction to the-upper ends of the transfer chutes. The types may engage with the bars 12 in any preferred manner; it is only essential to my present invention that the types have certain shoulders 16 which ride over the bars 12 and which form the means by which the types are held at the upper ends of the transfer chutes. "In practice I cut notches orchannels 17 on each side of the typesfihe upper sides of these notches formingthe shoulders 16; and these notches lie loosely'in engagement with the bars 12 of. the .maga-.

zine. lVith a sufliciently loose lit,the' types slide easily down the magazine bars and move easily and quickly into place at the upper end of the transfer chutes."

The transfer chutes 20 (of the character shown in my said patent) are formed with a front wall 21 against which the types bear when they are delivered from. the magazine. Divisirn strips 22 form the side walls of the chutes 20, while back wall 23 may be formed in any convenient manner. I'Vhen a type 14 is pressed forwardly in engagement with the type to hold it from dropping down thechute until desired; and, although other means may be used, this holding means preferably takes the form of a yielding device in the form of a small spring 30 with a curved lower end projecting in under the shoulder 16. It will be understood that I may use such a yielding or releasable means in engagement with any part or any shoulder cnthe type; for convenience and simplicity I prefer to use the'shoulder 16. As a type moves off the end of the magazine it moves over the lower curved end of the spring 30 and is held by the spring against downward movement. The weight of the body of type back of the single type holds the single type in engagement with the spring. The single type is releasablv held wholly in the trans fer chute and entirely free of the magazine.

My preferred means for giving each type an initial impulse is electro-magnetic in its nature. Other impulse means may be used; the electro-magnetic means is simple and effective in operation and control. I employ a small solenoid 35 whose plunger core 36 is normally held in position by a small spring '37. A plunger rod 38 carries a plunger 39 at its lower end. Plunger 39 may preferably be made of some material which will not injure the face of the type, such as fiber or the like. The action of the solenoid is controlled by any suitable key arrangement. hen the solenoid is energized it immediately pulls its core downwardly, causing the plunger 39 to push the type 14 downwardly and to accelerate the type quickly; giving the type an initial impulse along the transfer chute. The plunger 39 preferably follows the type through a considerable movement, equal to almost the length of the type. As the plunger with- .draws, the next type is inposition to take the place of the delivered type and the instant the plunger passes above the heads of the type, the next type movesinto position.

It is seen that this movementis onlyieq'ual .to..the thicknessofthe type and that the next type is quickly'l'aositioned ready for a subsequent operation of the plunger. The. plunger will normally stand only "a very short distance above'zthe tops of the type;

so that, rather than being struck, the types are pushed downwardly and given a grad ual acceleration instead of being struck forcibly by the plunger. The acceleration given the type may be suited to conditions. I have found thatgravltational EICCElBItItIOIl is not sutlicient to advance a preceding type to a point whereit will not be interfered in tiers abo 'e each'other; the plungerrods' 38 being offset so as to reach the respectivet pes upon which theplungers 39 operate. There will be a separate magnet and 'plunger for each magazine and transfer chute: Any preferred means may be used for con trolling the electro-magnets; such "means being shown. in my said issued patent.

Hy invention accomplishes the objecthereinbefore set forth and eliminates all interference between types successivelydeliv ered from the several magazines. It 1s im possible for the type from one magazine tointerfere and clog the transfer chute for the reason that one type must necessarily be entirely out of the way before asucceeding type can come into place and before the succeeding type can be started along the trans fer chute. pulse causes it to be in a position at some distance along the chute before the next; type from the same or from another magazine can be started. A succeeding type cannot possibly catch a preceding type, because the velocity of movement is great enough to put a considerable space between two suc-* cessively delivered types even in the short As I hereinbefore stated, the time interval be-p tween successive releases of type is exceed-j time interval between their releases.

ingly small; so small thatthe operationis completed faster than an operator can ma nipulate a key. The speed of the machine is limited only by the speed ability of the operator manipulating the keys.
