TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented June 14, 1910.

Application filed September 21, 1906. Serial No. 335,616.

To all whom it may concern:

Fig. 3 is a side elevation of a sliding stop Be it known that I, LEE S. BURRIDGE, a 1 provided with graduated push rods or fincitizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in TypelVriting Machines, of which the following is a specification.

This invention relates to the tabulating mechanisms of typewriting machines.

The principal object of the invention is to simplify and improve the means for arresting the letterspacing carriage of a typewriter at any selected denominational point, and particularly to render the operators control of the carriage more certain and convenient.

In carry-ing out the invention, I provide a carrier to swing or move across the machine in front of the keyboard, and upon the carrier I mount denomination-selecting devices. This carrier is caused to move with said letter-spacing carriage, by means of suitable movement-transmitting mechanism pivoted upon the framework of the machine and connected to both the carriage and the carrier. In this instance, the movement-trans- Initting mechanism is in the form of a link age, which causes the carrier to have a parallel motion in a straight line across the machine, although other movementtransmitting-mechanism may be employed for the purpose.

The denomination stop mechanism herein illustrated comprises a series of finger-pieces or push rods of graduated lengths, and connected to a graduated stop, means being provided for arresting the finger as soon as the stop corresponding to the fi11gerpiece that is operated is adjusted to position to cooperate with a column stop mounted upon the framework of the machine. Said fingerpieces are shown projecting different distances through a plate which forms part of a carriage-releasing mechanism, and is arranged to be moved by the finger a limited distance for releasing the carriage during the last part of each stop positioning movement.

Other features and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a sectional elevation taken from front to rear of a Sun typewriting machine showing my improvements applied thereto. Fig. 2 is a rear elevation of the machine.

F 5 leasing plate with the denomination-selecting finger-pieces projecting therethrough. Fig. 6 is an inverted plan of the graduated stop member seen in elevation at Fig. 3.

In said Sun machine, the types strike rearwardly against the front side of a platen 1, which is mounted upon a carriage 2 traveling upon balls 3 across a framework 4, and pivoted with a letter spacing rack 5, engaging a pinion 6, the latter connected to an escapement wheel 7 provided with any usual escapement devices 8. Said framework includes a rectangular base 9 having the usual front keyboard 10 and resting upon feet 11.

Mounted upon the front bar 12 of the base by means of studs 13 is a rack 14 along which is adjustable a column stop 15, of which several may be provided, said stop having a pendent tooth 16 to engage any one of a series of steps 17 formed at letter-space intervals upon a stop-member 18, which is mounted upon a carrier 19, the latter arranged at the front of the keyboard and below the framework of the machine, and de signed to travel across the machine together with the carriage 2. Said carrier isillustrated in this instance in the form of a long bar extending from the keyboard back under the framework to the rear of the machine. It is mounted for a parallel motion upon the ends of two levers 20, 21, which are suitably connected to the framework of the machine and to each other.

22 designates the pivotal connection of the forward end of the bar 19 to the forward end of the lever 20, and 23 indicates the pivotal connection of the rear end of said bar to the rear end of the lever 21. The latter is fulcrumed at 24: upon a bridge 25 extending across the base, and the rear end of the carrier bar 19 isslot-ted at 26 to accommodate the swinging movement of 23 about the axis 24:. Said levers 20 and 21 may be connected between their ends in any suitable manner to cause their front and rear ends respectively to move in unison from side to side of the machine. For instance a link 27 at the beginning of a line of is a front elevation of a carriage-1e 'may be pivoted at 28 to the lever 21 and at 29 to an offset portion 30 formed upon the lever 20. By means of said connectedlevers, the bar 19 is caused to have a parallel mo tion across the machine.

in order to cause the pivot 22 upon the front end of the lever 20 to follow a straight path across the machine, a pin 31 is provided upon the lever 21 to engage a slot 82 formed in the lever 20, said slot being curved in such a manner as to produce the desired straight line motion of the pivot 2. The rear end of the lever 20 may be pivoted at upon the end of an idle link 84 pivoted at upon the framework 9. Since the pivot of the lever 20 moves in a straightline, it guides the carrier 19 in a straight path across the machine, so that the proper cooperation is made practicable between the column stop 16 and the various stepped stops 17.

The graduated stop-member 18 is mounted upon a base 36, which by means of two shoulder screws 37 is guided in backward and forward sliding movements in a slot 88 formed in the frontend of the carrier 19, whereby any of the steps 17 may be set back to position to engage the stationary column stop 16 upon the release of the carriage.

Upon the front of the plate 18 is provided a vertical flange 89 in which are fixed push buttons or finger-pieces 40 preferably arranged. alternately in two rows, Fig. 5, so as to give room for manipulation and being of graduated lengths. All of said push rods 10 project through holes formed in a vertical plate 41 extending in front of the flange 39. This plate is formed by bending up the front end of a bar 42 which slides at its rear end upon a screw 13, and is supported in front by said rods 40. Said bar 42 is formed with a rear lip to press backwardly a horizontal bar 45 extending across the machine and having at its ends arm 46 forming a bail, which is secured upon a transverse horizontal rock shaft 417. The function of said transverse bar is to release the carriage; one of said arms 46 being lengthened at 418 and connected by a link e9 to an arm 50, pendent from a horizontal transverse rock shaft 51, the latter carrying an arm having a finger to engage the cscapement devices 8, and force the latter out of engagement with the escapement wheel 7, whereby the carriage is released, and may run for ward freely under the influence of its driving spring 54, the latter connected to the carriage by a strap 55, Fig. 5. The movement of the carriage is communicated to the carrier 19 by means of an arm or frame 56 into the lower end of which is threaded at 57 the screw 23 of the parallel motion mechanism. Said arm 56 is hinged at 58 to the carriage so that the lower end thereof may swing out to accommodate the curvilinear movement of the screw 23 about the axis 24. Whenever any of the finger pieces 10 is pressed forwardly by the finger, the stopmember 18 is thrust back and during the last part of such movement the finger engages the carriage releasing plate 41, and moves back the same together with the slidebar 12 and transverse bar 45, thereby releasing the carriage. The plate 41 is arrested in its backward movement by engagement of the front end of a slot 59 with the screw 48, Fig. 4:, and this determines the ex tent of displacement of the stepped stop member 18 from normal position, and hence, which of the stops 17 shall be brought to position, to engage the column stop 16. If the extreme left hand button 40 at Fig. 6 is selected and pushed back, the movement of the member 18 would be least, and the extreme left hand stop 17 would be positioned to engage the stop 16. Upon the other hand, if the extreme right hand push rod 40 is operated, the plate 18 would be given an ex treme movement, and the extreme right hand one of the set of stops would be brought into position to engage said stop 16; while any of the intermediate stops 1? may be brought into use by operating its corresponding push rod or key 40. The carriage releasing mechanism is returned to normal position by a spring 60, and the stop member 18 is returned by a spring 61. The carriage 2 shifts up and down to enable different types to print.

The carriage track frame 62 shifts up and down upon ball-bearings (38, Fig. 2, as usual in the Sun machine, and it will be understood that there is sutlicient play or yield at the joint between the lever 21 and the bridge 25, as well as at the other joints of the parallel motion mechanism to accommodate the up and down shifting of the carriage 2, which is very slight.

It will be seen that owing to the arrangement of the denomination stop carrier at the keyboard, the operator can very conveniently control the movements of the carriage both for tabulating work, and also for re-- turning the carriage to begin a new line, or otherwise manipulating the carriage; the provision of a carriage releasing member upon the carrier controlling member 19 at the front of the keyboard being a great convenience.

Variations may be resorted to within the scope of my invention, and portions of my improvements may be used without them.
