TYPE-WRITING- MACHINE.

Specification of Letters Patent, Patented July 5, 1910.

Application filed April 14, 1909. .Serial No. 489,915.

To all whom it may concern.

Be it known that I, GEoRonA. Sum, citi- Ilion, in the county of Herkimer and State of New Y ork, have invented certain new and useful Improvements in 'lype-Vi'riting lv[a-- chines, ofwhichthe following is a specification.

My invention relates to 'typewriting mas chines and more particularly to type actions for such machines and the main object of the invention is to provide an easier and more eflicient type action and one in which there will be less wear upon the parts.

A further object is to provide for adjust mentbetween certain of the parts.

, To the above and other ends which will hereinafter more fully appear, my invention consists in the features of construction, ar-

rangements of parts and combinations of devices to be hereinafter described and particularly pointed out in the appended claims.

'1 IS a side view of a In the accompanying drawings wherein like reference, characters indicate corresponding parts in the various views, Figure type action embodying my invention, together with certain other parts associated therewith. Fig. 2 is an enlarged detail fragmentary perspective view of a sub-lever and a tool used in adjusting the parts. Fig. 3 is a view corresponding to Fig. 1 but showing the disposition of the parts as they appear when the type bar is in printing position. Fig. 4 is a front elevation with a part of the machine sectioned away and part-s broken away, the View showing several of he sub-levers at si es of the system .with the key levers pivoted thereto.

I'ha've shown my invention embodied in I the present instance in a front-strike type- I writing machine of the same general character as the Monarch machine, though it should be understood that the invention may be embodied in other styles of machines.

The frame of the machine comprises a base 1 and corner posts 2, the latter being surmounted by atop plate across which the carriage (not shown) travels in theusual manner. A type bar segment 3 constitutes asupport for type bar hangers 4 to which type bars 5 are pivoted at'6. The construction is such that the type bar segment and the segmentally arranged upwardly and States, and resident of rear end I 'rearwardly striking typebars may be shifted relatively to the platen 7 diagrammatically shown in the drawings, as in the Monarch machine. Each of the type bars is pivotally connected at 8 to a pull link 9 pivoted at its rear end'as at 10 to an upwardly extending arm of an angular sub-lever 11 pivoted at 12 to a ke lever 13 which is provided with the usual nger key 14 and a restoring spring 15. The key leversare or may be provided with curved contact faces 16 on the upper curved treads or contact faces cooperate with a fulcrum plate 17 secured to the base of the machine. The key levers are guided at their portions by a guide comb 18 and are guided at the front portions by a guide comb 19. Each sub-lever has an angular or off-set arm or portion slotted or bifurcated at 20 to receive a fulcrum rod or bar 21 which extends transversely beneath tlie'key levers and is secured at its ends to depending lugs-22 which base of the machine. Each sub-lever is provided with oppositely disposed jaws which embrace the fulcrum rod. One of these jaws is in the nature of a fulcrum link 23 pivoted at 2ft to one arm 25 formed by the bifurcated portion of the sub-lever. The other jaw is formed by the other member 26 of the bifurcated portion of the sub-lever. Each link 23 is slottedat 27 to receive the portion or arm 25 of the sub-lever to which the link is pivoted. The pivot 24 of the link or shoe 23 is preferably secured to the two ears formed by the slot 27 in the shoe and turns with the shoe within a perforation in the arm25 and in conse uence the pivot pin 24 is in the nature'oi a headed rivet free to turn in the perforation in the bell crank. The lower end portion ofeach link 23 isrecessed as at 28 to straddle the fulcrum rod 21 and to form a broad semi-cylindrical bearing face 30 for contact with the cylindrical rod, the link being free to turn on'the rod. The edge 29 of the cut-out 20 in the sub-lever is so shaped. that, in the movement of the sublever around the fulcrum rod 21, the edge 29 will' bear lightly against the fulcrum rod and will thus prevent the ide link from being accidentally displaced from the rod and will maintain a cooperation between the sub-lever and its fulcrum rod. It will be s een from an inspection of Figs. 2 and 4.

edges of the rear portions thereof, which project downwardly from the that the bearing face 30 of each fulcrum link 23 which contacts with the fulcrum rod 21 is considerably wider than the thickness of the sub-lever so that a broad contact face or wearing shoe is provided between each fulcrum link and the fulcrum'rod. Each sub-lever, on the edge thereof opposite the bifurcation 20, is slotted at 31, in a direction transverse to the general. length of the subleve'r, the slot 31 extending toward the slot 20. The lower portionof the sub-lever is provided with shoulders 32 and 33 on opposite sides of the bifurcation. This slotting of the sub-lever at 31 is to weaken the metal at the neck, formed between the two slots 20 and 31 so that the portion of the sub-lever below said slots may be bent around the neck as a center and thus provide means whereby the oppositely disposed jaws 23 and 26 of the sub-lever may be adjusted toward or away from each other, If the jaws are to be brought closer together a suitable tool such as'thatshown at 34; in Fig. 2 may be inserted in the slot 31 and employed to force the jaws at each side of the slot apart, there by forcing the oppositely disposed jaws 23 and 26 closer together. If, on the other hand, the jaws 23 and 26 are to be more widely separated, then an ordinary pair of pliers may be employed, each jaw of the pliers engaging one of the shoulders 32 or 33. A. compression of the pliers will bring the jaws on opposite sides of the slot 31 to gether, thus forcing the jaws 23 and 26 apart. It will be understood that the pivot 24c under all relative adjustments of the jaws 23 and 2G maintains a tired relation with the sub-lever above the slot or cut-out 20 therein The effect of the adjustments previously described is to raise or lower the arm 26. If through reaction of the parts the face or edge 29 of the jaw 26 should in time become slightly worn this wear may be taken up by an adjustment of the jaw 26 in the manner the adjustment de described. Moreover, scribed enables each sulrlever to be individually adjusted at its fulcrum to take up any undue looseness at the fulcrum without adjusting the escapement connections as was the practice in some instances heretofore.

The provision of the fulcrum link. 23 in this construction divides the movement of the parts and distributes and reduces the wear. Thus, instead of the upper arm or part 25 of the sub-lever contacting directly with the fulcrum rod as in the Monarch machine, the sub-lever receives a slight pivotal movement with reference to the fulcrum link 23 and the link itself receives a slight pivotal movement on the fulcrum rod, These movements are so slight, however, that no materialwear at the pivotal points is pro duced and a broad contact face 30 of the shoe or fulcrum link 23 hearing on the fulcrum rod distributes the wear between the I by" Letters fulcrum rod. and fulcrum link and reduces such wear to a' minimum; Moreover, this construction provides an easier and more eliicient action of theparts, affording as it does a ivotal movement-of the guide link on the fulcrum rod as distinguished from a sliding and turning movement on the rod.

Various changes may be made without departing from the spirit and scope, of my invention.
