TYPE-\VRITING MACHINE.

Specification of Letters Patent.

Patented 15, fijtt).

Application filed May 18, 1903. Serial No. 15?,875.

TooZZ whom it may concern:

Be it known that I. CHARLES H. SHEPARD, citizen of the United States. and resident of the borough of Brooklyn. city of New York, in the county of Kings and State of Xew York. have invented certain new and useful Improvements in 'lype-Friting Machines, of which the following is a specification.

My invention relates to typewriting machines and more partitailarly to the type actions thereof. and the object of said invention is to provide a simple and efficient type action wherein the full force or pressure of the finger on the key will not be positively applied to the type' in making an impression.

To the aboie and other ends which will hereinafter appear. my invention consists of the features of construction, arrangements of parts and combinations of devices to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure l is a fragmentary sectional elevation of a suiticient number of parts of a typewriting machine to illustrate my invention. Fig. 2 a

detail plan view of one of the type bars and hangers, the type bar being shown in a printinglposition. Fig. 3 is a fragmentary detail sectional view showing the outer or free end of the type bar. the view being on an err larged scale. Fig. 4: is a plan view of the same. Fig. 5 is a fragmentary detail plan view on "an enlarged scale of a modified.

form of construction. Fig. 6 is a vertical sectional view of the same taken on the line of Fig. 5. view on an. enlarged scale of the spindle or abutmentshown in Figs. 5 and 6. Fig. 8 is a fragmentary detail side elevation partly in section of a modified form of type bar embodying my invention. F ig. 9 is a plan View of the same.

Key levers 1 of any suitable construction are provided with finger keys 2, and suitable connecting links 3 are pivoted at 4 to straps 5, each of which surrounds itsassociated key lever. Each of the links 3 in the present instance is shown as a two-part link. such as those ordinarily employed in the No. 6 Remington machine and the upper end of each link is connected at 3 to a crank arm 6 Fig. 7 is a detail perspective.

' of a type bar or printing instrnmentality 'that comprises two memberszone, body portion 7 that is pivoted by its trunnions 8 to a hanger 9, and the other a type carrying member 10. In the construction shown in Figs. 1. 3 and 4, the body portion of the type bar is provided at its free with a bearing portion or socket 11 that extends at substantially right angles to the lengths of the body portion of the bar and receives the loosely disposed type carrying member or block 10 therein. The type carrying member is recessed at 12. and a pin 13 extends through the bearing portion of the bar and into the recess so as to limit the movement of the type carrying member relatively to the body portion of the bar. and prevent it from turning in its bearing.

Each yoke-like type bar hanger 9 has the side arms thereof extended toward the print-- ing point so as to form supporting arms 9 nature of a spindle that extends between the supporti: g portions or arms 9* of each hanger and constitutes a connection between them and which projects into the path of the body portion 7 of the associated type bar, in the .movement of a bar to the printing position, as clearly represented in Fig. 1. Each spindle 1% is preferably sheathed as indicated at 15 with a padof comparatively soft substancesuch as leather, felt or the like. to receive the impact of the body portion of the bar in its movement to the printing position and thus avoid the objectionable nolse which would occur by an impact of the bar directly against the metallic spindles 14 in the movementsof the bars to the printing position. From-an examination of Figs. 1 and 3 it will be understood that the disposition of eachabutment 14: is such that; the body portion 7 of the associated type bar reaches contact therewith, or with the sheath on said abutment, before the type arrives at the printing position or contacts with a platen 16, or the paper thereon. The momentum of the type bar in moving to the in-its bearing. thus bringing the face of the type to the printing ortion 7 of the bar as been arrested by for a stop or abutment 1 L which is in the its abutment 14. It will therefore be seen printing position is, however, suflicient to enable the type carrying member to slide point after the body' be positively applied to the type. I I While the various type bars throughout the systenrmay be constructed in accordance with my invention, it should be understood that the invention 'is particularly valu-' able for those type bars which carrythe types of the punctuation marks such as the period and comma inasmuch as the types for these marks or characters are liable to puncture the paper in the ordinary operation of the machine, and by my invention the liability of the sheet being punctured, is overcome. The invention, however, is also of value when applied to all of the type bars of the system inasmuch as it enables the type carrying member of each bar to recede rapidly'from the printing oint independently of the body portion'o the bar after the impression is made, and positively prevents the operator from holding the type at the printing point by a long,--following and lingerin stroke upon the key, thereby avoiding a burring of the imprint and providing a clearer and better character of work. I

In the construction represented in Figs. 5 and 6 the spindle or abutment 14: is providedwith a head 17 and a screw-threaded end 18. This spindle is loosely seated in bearings in the arms or supports 9 of itsv hanger; with the head 17 on the outer side of one arm'9 and a screw-threaded end projecting beyond the other support 9" where it cooperates with a nut 19 which, when Screwed tight, exerts a pressure to maintain the spindle in the position to Which it is turned. An eccentric 20 is formed on each sp ndle intermediate of the ends thereof andthis eccentric is sheathed --s indicated at 21 with a pad of comparatively soft material such as felt or leather, against which the body portion 7 of the associated type bar is adapted to strike. It will be understood that by turning the spindle, different portions of the eccentric 20, which constitutes the abutment, will be interposed in the path of the bodyportion of the type bar in its printing movement; that the point of arrest of the body portion. varied, and the force of impactof the type carrying member may in a degree be rcgulatcd. The adjustment of the eccentric 2O likewise compensates for wear between the' abutment and the body portion of the type bar at the point of impact between the two.

In the construction illustrated in F 8 and 9, a modified form of type bar is shown wherein the body portion 7 isbifurcated at its free end,as indicated at 21, and receives of the bar may thus be within the bifurcation a portion of the type carrying member. A pivot extends through the two members to pivot ally unitc them and to form a knuckle joint that enables the type carryingmember 10 to swing to the-printing position after the body portion 7 of the bar has been arrested by its cooperating abutment. 22 of the type carrying member is adapted to contact with the end wall of the bifurcated portion 21 of the bar, as indicated at 24:, so as to limit the movement of the type carrying member in one direction with relation to the body portion of the bar. It will be observed thatv in Figs. 1, 2, 3 and at a sin-.

maintain the hangers in their adjusted posi; tlons. In both constructions shown, it Will I .be seen that the ty 1e block or type carrying member has a limited movement relatively to the body portion of the bar in the general direction of movement of the bar" and at substantially right angles to the length thereof, to complete the printing stroke solely by momentum after the body of the bar has been arrested. I

From the broad aspect of my invention it is immaterial by what portion of the machine the. abutment which cooperates with each type bar is carried, and it is immaterial what the construction of this abutment is, so long as it arrests the body portion of the type bar before the type carrying member thereof reaches the printing point.

It should be understood changes may be made without departing from the spirit of my invention.
