Specification of Letters Patent.

Patented J une 5, 1908;

Original application filed August 27, 1901, Serial No. 73,460. Divided and this application tiled August 1, 1905. Serial No, 272370t .'lU 1MM w/wm it may concorre;

Be it known that I, EDWARD B. Hass, a citizen of the United States, residing in the borough of Brooklyn, city of New -York, State of New York, have invented certain newr and useful Improvements in Writing- Machines,A of which the following is a specification.

In my Patent No. 700,687, dated Mey V20, 1902, application for which was filed Apr-i126, 15101, l have shown and claimed a structure containing lexible type-bar-actuating conv nections hatfingthegeneral construction and mode of operation of those herein disclosed. That patent shows and claims, however, de tails of .construction not herein disclosedV and Yto which the claims thereof are drawn, the

right being reserved therein to make generic claims in my application, Serial No. f of which this case is a division.

"he construction herein disclosed is speciic land subordinate to generic claims made in my application filed August 1, 1905, Serial No. 272,171, which is also a division of my a plicaton, Serial No. 73,460. 1 No detachab e adj ustable fixed pieces or anchor-points (hereinafter described) in an organization of the general character herein shown are claimed in my application Serial No. 73,460.

The accompanying drawing is a vertical longitudinal section showing so much of a machne'as is deemedA desirable to illustrate the invention. o 'Y The drawing shows a ronteetroke t e-bar writing-machine. It is contemplate that each typebar shall have two characters thereon and that either the type-.bar segment or 'platen shall be shifted to print at will either upper or lower case letters. As shown, provision 'is made for shifting the-platen.

The frame is of any appro riate construc tion. At a suitable ont be ow the plane in which the platen is coated is mounted the type-bar segment 1 in which the type-bars 2 are pivoted on a ro Y or wire, as usual. They lie toward the machinaagainst asegmentai rest. To the heel or projection of each typebar is attached the rear end of a exingconnection, the front end of which is secared te a ixed 4point or lpiece 4, adjustably and detachablymounte nection in a` se ent 5 located toward the front of the mac ine and in front of the trans- 'sistance and type-bar velocity darin by YAa" slotendsset-screw een;

verse plane in which` the heads of the type-V `applied to the type-bars, and springs may be applied to the key-levers. I a universal bar 12 be empio ed beneath the key-levers, it may, as nena be urged up'st'ardly a einst the key irlevers by spring pressure. ithe or both arran ements may be employed. It is suflcent t at the spring reaction wherever and however applied shall properly assist in l returning the type-bars to their position of rest, and so normally maintain them.

To secure a uniform depth of depression ci the har-pieces, the points of connection of the li 6 with the type-bars or the angle at which the links 7 are disposed may be rtaried. When c. nger-piece and its key are depressed, link 13 is drawn down, flexing the connection downward and swi g that part of it in front of the point of exure-a e., link -emund its point of connection with the fixed piece thus drawing the rear link 6 toward the front of the machine and actuating the type-bar by a pnli. This movement is characterized by a mmirnumo resistance at 'the start with correspondingly-'low velocity of the type-bar and an increase in 1E- t e complete downward excursion of the gerpiece.

Two key-levers only are shown. 9x is the center key of .the upper row, connected with the central ile connection running to the lowest point of t e segment 5. 9Y is one of the end keys of thehjont row and is connected with a flexing connection running to the end ofthe segment. Y

The construction of the carri e and platen and 'mechanism for shitng the atter may be of any appropriate character. 'As shown, the carriage travels upon rails 29 and 30, mounted in brackets located at the sides of the frame. The platen 31 isrnounted in a frame IDO 32, carried in the ends of parallel pivoted arms riage. The lower arms 34 are fast to the ends of a rock-shaft 35, from the center of which projects an arm 36 whose end is acted upon by a cross-rod 37, held in the ends of bell-crank levers 38, located at the sides of the machine and fast to a rock-shaft 39. The bell-crank 38 at the left-hand side of the machine has connected to it a link 40 to be suitlbly actuated on the depression of a shiftlhe relation of the type-bars and flexing connections is much the same, affording substantial uniformity of behavior. The structure is light, cheap, and simple and affords a marked refinement of touch of the fingerpieces. Obviously when the device or connection for operating the flexing .type-baractuatingl connection is applied at the hingejoint of t e latter tensile strain only is exerted upon the parts thereof from the point of flexure to the opposite ends, respectivel and such parts may therefore be very lig t and inexpensive and preferably are made of wire. Preferably the joints between the members of the flexing connection and between it and the iixedoint and type-bar are such as to allow slig t twisting movements. This is particularl desirable at the type-bars near the ends o the segment.

The arrangement designated by me a fiex- 1n connection may have in some forms the ful operation of a reverse or accelerating toggle and in all formsI is of the nature of such a toggle. As illustrated, application of power thereto is in a line lintersecting one drawn between the fixed poixit and the point of attachment to the type-bar.
