SPECIFICATION forming part of Letters Patent No. 576,2,s,aateu February 2, 18er.

Original application filed J' uly 28, 1892, Serial No.

To altri/71,0712, t may concern: i

Be it known that I, BURNHAM C. STICKNEY,

fa citizen of the United States, and a resident of Elizabeth, in the county of Union and State" ofgNew Jersey, have invented certain new and useful Improvements in LType-Vriting Machines, of which4 the following is a specification.

This invention relates to that class of type- 'Writingmachines made the subject of an ap In the accompanying drawings, Figure 1 is a vertical longitudinal section of atype-writing machine embodying my present improvements. Fig. 2 shows the positions assumed by the parts when the type-bar'and its asso.

ciated mechanism have returned to their nordepressed position.

mal positions, the nger-key being still in its Fig. 3 is a'vertical longitudinnl section on a larger scale and in slightly-modified form, showing the position of the parts just after'the tripping acthas taken place, the type-bar being initsprinting position and the key in its depressed po# sition; and Fig. 4is a horizontal section taken l at the line Z Z of Fig. 3, looking in the direc-l 4 Vtion ofthe arrow and showing a portion of the key-levers broken away.

In the several views the same parts will be found designated by the same numerals of' reference.

1 designates the framework of the machine; 2, the top plate or type-ring; V3, the typebars; 4, the connecting-rods, 'and 5 the usual power-driven paper-carriage, The paperlcarriage is provided with a feed-rack ,6, with which caperates a spacing-dog `and a detaining-dog S, mounted upon a trunnion or rocker 9, held by a bracket 10 and actuated by a link 11, connected at its lower end to an arm ,12, secu redto a transverse rock-shaft 13,

mounted-in the base ofthe machine at 14 and provided on each side withforwardly-extending arms 1 5, thefront ends of which are united by a universal bar 16, extending transversely of the maehineparallel with said rock-shaft 13 and arranged beneath a series of levers 17 pivoted at their forward ends toa transverse fulcrum-rodl 8 and having a uniform motion. The connecting-rods 4 incline inwardly,'and their llower ends terminate in, a line transversely of the machine andare pivoted at 19 to the levers 17 in rear of the fulcrum-rod 1S. The escapernent or spacing mechanism may be of any usual or suitable construction. A spring 2O is provided to return the universal bar .of the spacing mechanism to normal position after releasement, as'will'presently appear. i i l p Y Above the levers 17 are arranged key-levers 21, pivoted at their rear ends to a transverse fulcrum-.rod 22, provided at' their for- Ward ends with keys 23 and bearing between their ends pivoted trips 24., Springs 25 are provided to return the key-.levers to normal position upon being relieved from finger- -pressure.

r `The trip 24 is pivoted tothe key-lever at a point 26 in rear of the center of the machine (considered transversely) and is provided with an arm or lug 27, which normally and during the descent of the key-lever bears against a pin 28 upon the key-lever, being at this time held against said pin by the pressure ofspring 29, arranged'between the key-lever and the trip.

The lower end of the trip is` arranged to bear upon the rear end of the type-bar-eperating lever 17 toactuate and release the same and its 'connectedtype-bar and the universal bar. A pad-30 is provided beneath the keylevers to arrest their motion after releasement of the type-bars.

` In operation, when a key-lever 21 is depressed, the trip 24 bears down upon the rear end of lever 17,' depressing it and carrying down its associated connecting-rod 4, vibrat-' ing the type-bar 3 toward the platen. During 'its depression the lever 17 forces 'down the universal bar 16, depressing the arms 15,

rocking the shaft 13, vibrating the arm 12 upwardly, and throughv the link 11 actuating IOC will`benow more specificallydescribed. Dursecure by Letters Patent, is

1 sume their normal positions independently 'of the key-lever. 21, which is still depressed, `as shown at liig. 2whereupon other keylevers may be manipulated withoutrelieving vallel for the entire length of the lever and .cerned, since l do not wish to be limited in the feed mechanism. .'lh rough the feed mechl anismdescri bed or any other suitable feed' mechanism the carriage is fed the necessary letter-space distances as the impressions are made. At a predetermined time the lever l17 and its associated type-bar, together with the l universal bar 16 and the feed mechanism, are .released from the control of the key-lever and .returned to their normal positions independently and in advance of said key-lever, all as ing said. actuation f lever 17 by trip 2t the latter moves rigidly with the lever 21, being held against the stop 28 on said lever by the vspring `29.V 'l` he ,active lower end of the depending trip 2i therefore moves liu a path de* scribed by an arc of a circle drawn from the pivot 22 as a center, as indicated by the dot.- -ted line c, while the rear contacting end of the lever 17 moves in a path described by an are of a circle drawn from its (pivot 1S as a center, as indicated b v the dotted line l). lt will be seen that these arcs diverge and intersect each other, and-this point of intersection represents the point of disengagement between the trip and the lever 17 and which occurs just before the type strikes the paper on the platen. B y reason of such divergence and intersection thetrip'l slides oii' of the lever 17 after depressing it, and thereby releases the same, Fig. 3, and permits it, to gether with its associated type-bar and, the universal bar and spacing mechanism, to rethe vfirst key-lever from finger'- pressure. Upon relieving the key-lever 21 from pressure it resumes its initial position under the return pressure o f spring 25, during which motion the trip 2t rides along the end of lever 17 and vibrates independently on its own pivot against the tension of the sprin g 29, and upon risingabove said end of. lever 17 it vibrates forwardly under pressure of spring 29 and resumes its initial position with the lug resting against the stop 2S, as shown at Fig. 1. It will be seen that the top and bottoni edges of the lever 17 in Figs. 1 and 2 are parthat `the trips are formed with jogs or shout. ders at their lower active ends, while at Fig. 3 the lever 17 is beveled at its rear end, and the lower end of the trip is parallel-sided; but these differences are .not material in so far as my present improvements are conany wise to any peculiarity of construction or .form of leither the lever or the trip not specifically set forth in the claims,

What I claim herein as new, land desire to 1. ln a type-Writin g machine, the combina-- tion with a type-bar of a type-baroperating lever connected thereto,and a keydever carrying a vibratory trip 'and a stop and a spring,

thesaid trip in the descent of said lever being heldrigidly by said spring'and stop and contacting withsaid type-bar-operating lever,

and the said trip also vibrating in an are about the pivot of the said key-lever, until by divergence it parts com pany withsaid type-baroperating lever, substantially as set forth.

2. In a type-writing machine, the combination witha type-bar of a lever for operating the same and akeydever carrying avpivoted trip adapted to actuate the type-bar-operating lever and to detach itself therefrom by divergence, and means for holding said pivffoted trip rigid during the time it is actuating said type-bar-operating lever and detaching itself therefrom, substantially as set forth.

- 3. In a type-writing machine, the combination of a type-bar, a lever connected thereto, and a key-lever, the said key-lever and the said type-bar lever'having each separate fulerums, and the key-lever having a part adapted to contact with the type-bar lever,

the said part and the said type-bar lever vibrating Ain arcs which intersect each other, and the said part separating from said lever in the downward movement at the point of intersection ofsaid arcs, substantially as set forth. i

4;. In a type-writing machine, the combination of a lever connected to a type-bar, a key-lever having a trip jointed thereto and adapted to bear at one end upon said typebar lever, the said trip being held rigidly during the downward movement of the key-lever and'operating to depress th'e type-bar lever and toslide along and off the same, whereby the type-bar and its associated lever may return to normal position independently and in advance ofthe key-lever, and whereby during the return of the key-lever to its normal position said trip may vibrate and resume its proper position relatively to the type-bar lever, substantially as set forth.

5. In a type-writing machine, the combination with a circular series of type-bars of a series of rods attached at one end to the typebars and at the other end toa series of operating-levers, the lower ends of the rods be- A ing arranged in a straight line, and a series of key-levers separably connected to said type-bar-ope atinglevers, substantially as set forth. 1

G. ln a typecvriting machine, the combinationl with a circular series of type-bars of a series of reds depending therefrom and ter-- minating in line transversely cf the machine and connected at their lower ends to a series of operating-levers pivoted at one end and having uniform motion, a series of keydevers, and a series of trips between the key-levers and the type-bar-operating levers, substan tially as set forth.
