TYPE-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 749,773, dated January 19, 1904.

Application filed February 27, 1903. Serial No. 145,300. (No model.)

To all whom, it may concern.-

Be it known that I, FRANcIs B. CONVERSE, J r., a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Type- Setting Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to a type-setting machine of the general character set out in my prior patents, numbered 601,706 and 717,171, granted to me April 5, 1898, and December 30, 1902, respectively, the object being to simplify the construction there shown, rendering it cheaper to make and more efiicient in service.

In each of the patents mentioned there is shown a type-setting machine comprising vertical type-cases having a plurality of channels, series of toothed ejectors, one for each channel, a pair of toothed rollers between which the ejectors lie, and mechanism operated by the finger-keys for causing the corresponding ejector to move to cause its teeth to engage the teeth of one of the rollers, whereby the ejector is fed forward, the ejector automatically moving into engagement with the other roller and being returned at the end of its forward movement. Such a structure,broadly,is shown in the embodiment of the invention herein illustrated. The particular improvements which constitute this invention relate to the mechanism for moving the ejector into engagement with the rotating roller and mechanism for unlocking any engaged ejector when the same becomes blocked by absence of type in the channel. These features will be hereinafter described, and definitely set out in the claims.

In the drawings, Figure 1 isa vertical section through the type setting machine at the ejector mechanism and at the keyboard. Fig. 2 is an enlarged vertical section of the ejector mechanism near the two toothed rollers. Fig. 3 is a vertical cross-section of the ejecting mechanism substantially on the line 3 3 in Fig. 2.

Fig. 4 is a side elevation of the ejector portion of the machine, and Fig. 5 is a plan view of such portion.

Referring to the parts by letters, A A represent suitable frame-standards, on the upper ends of which the horizontal frame A is mounted. Resting on the forward end of this frame and extending upward therefrom are the type case or cases B, covered bya plate 6 and divided into a plurality of channels 6. The type (designated by 6 are surmounted by followers I). Extending downward from the front edge of the frame A is the race-plate C, carrying a ledge 0, around which the type ejected forward from thetype-cases are adapted to swing, whereupon they pass foot downward into the race-plate.

J ournaled in a pair of brackets a, carried by the frame A, are two toothed rollers D and E. These rollers are geared to rotate in the same directionz'. 6., their proximate surfaces in opposite directionby the gears d and e on said rollers, respectively. These gears are connected together by the idle gear F. In the machine shown the rollers are rotated by a pulley on the shaft of the roller E and frictionally clamped thereto by a spring g, bearing on washers g and clamped by nuts 9 Between the rollers D and E are a series of ejectorbars J, one for each type-channel. These ejectors are guided in suitable frame members and have at their forward ends reduced portions j, adapted to extend in the typecases. Adjacent to the rollers D and E these ejectors have on their upper and lower edges teeth 1" and At the rear end of the teeth j is a notch f and at the front of the teeth j is a notch 1'. Now if an ejector is raised the teeth come into engagement with the teeth of the roller D, and the ejector is advanced, ejecting the lowest type in the type-case until the notch relieves the engagement, when the ejector drops, bringing the teeth 1' into engagement with the roller E, which retracts the ejector until this engagement is released by the notch coming over the roller E.

The mechanism so far described is itself old,

is a feature of this invention and will now be described.

Mounted in the keyboard-box K carried by the frame-standards A are series of key-levers L, pivoted on the box K and adapted to be individually depressed by finger-keys N. Stems of these keys fork over the key-levers, which are flat bars on edge and are held thereto by pins n through the key-stems. Slidably guided in the frame members is just above the rear ends of the key-levers L are a series of flat rods P, one for each key-lever and for each ejector. At its upper end each rod P takes through and is guided by a slot 7' in a framebar carried by the brackets a and preferably composed of a notched member R and a bar 7'. Secured to the under side of the bar R are a series of springs S, bearing on the front side of the raising-bars P, giving them a slight pressure rearward. Near the upper end of the bars P on their rear side are notches 19. These notches in their normal position of the parts, as shown in Fig. 1 and in full lines in Fig. 2, are idle, and the rear edge of the bars P rests against the rear wall of the slot 4". Now when a finger-key N is depressed the corresponding rod P is elevated, and the upper edge of the notch 12 becomes flush with the top of the bar 7", whereupon the spring S forces the bar P slightly rearward suflioiently to cause it to hook over and hang on said framebar 7'. This elevation of the frame-bar raises the ejector J above it into engagement with the toothed wheel D, which at once feeds forward the ejector. This engagement continues notwithstanding the pressure is removed from the finger-key by reason of the raising-bar P having hooked over the frame-bar r until at the extreme forward position of the ejector J the shoulder constituting the rear wall of the notch J impinges the rear side of the bar P, forcing it forward against the light spring S. At the same time the notch comes under the roller D and releases the ejector, whereupon both the ejector and the bar P fall by gravity, the pressure of the spring S not being heavy enough to support the bar P. The bar P being comparatively long, its angular movement is so very slight that the guide It may make substantially a tight fit without binding the bar P. This makes a very simple and effective means for causing the engagement of the ejector and enables the touch on the finger-keys to be very light and very quick. As soon as the key is depressed the operation becomes automatic, and the finger may be removed from the key as quickly as it is possible for the operator to do it, the speed of the operation being limited only by the operators manual dexterity. Dotted lines in Fig. 2

show the engaged position of the ejector and bar P, and the dotted lines in Fig. 1 show the corresponding position of the key-lever.

Surmounting the type 6 within the channels of the type-keys are followers 6 When the type are exhausted, these followers block the advancement of the corresponding ejectors. This blocking stops the setting action, the pulley Gr slipping by reason of its frictional engagement with the roller E. To release the ejector raised and locked by these circumstances, I provide the frame consisting of a rod T, extending across the ejector and carried by arms t from a rock-shaft T, journaled in the frame-standards a. The weight of this frame if released is suflicient to depress and unlock any engaged ejectors. The frame is normally held elevated and out of action, however, by the engagement of a lever U with an arm 6, extending from the shaft T,.the lever U being normally elevated by the spring V. This much of the releasing device is shown in my prior patent, No. 717,171, referred to. The lever U is secured to a rockshaft Z, which extends across the frame and has secured to its front side a plate .2, at the upper end of which is a rib .2, which stands opposite the notch p in the depressed position of the bars P. When any ejector is blocked by the exhaustion of a type-channel, the lever U is simply drawn downward by the operator, and this turns the bar Z and swings forward the plate 2, andthe rib 2' engages and forces forward any bar P which is elevated, the rib having no effect on the bars which are not elevated. This will be seen from the two positions of the bars P illustrated in dotted lines and full lines in Fig. 2. As soon as the elevated bars P are released the descent of the frame T on the blocked ejectors releases them from engagement with the roller D.

It will be seen that the improvement herein set out does away entirely with the bell-crank fingers between the rods from the key-levers and the ejectors, as shown in my above-mentioned patents. This simplifies the construction and renders it more eflicient.
