Application filed March 30, 1906, Serial No. 309,016. Renewed September 17, 1907. Serial No. 593,326

To all whom it may concern:-

Be it known that I, JOSEPH H. JACKSON, a citizen of the United States, and resident of Hamilton, in the county of VVentworth and Province of Ontario, Canada, have invented new and useful Improvements in Type- Writing Machines, of which the following is a specification.

My invention relates to improvements in typewriting machines, in which a segmental carrier carrying a series of type arms fulcrumed thereto is suitably mounted in the machine, and is adapted to carry said type in consecutive order to writing position to and at right angles to the impression roller, or platen, by the operation, or the depression of a key.

The objects of my invention are, first, to provide a machine, in which the type is carried to one common center in the segmental carrier and-therein positioned; second, to

provide means for engaging thet pe with the impression surface by pressure, t iird, to provide a silent and noiseless typewriter while the same is in operation, fourth, to provide 'means for allowing the upper or lower case of type to be operated by pressure against the impression surface, fifth, to afford facilities for bringing type to position and forwarding the same at right angle to the impression surface at one noiseless operation, and sixth, to provide means for attaining equalized pres-' sure of the type. I attain these objects by the mechanism illustrated in the accompanyingFdrawing in which: i igure 1, is a sectional side of the machine, and in normal position. Fig. 2, is a plan of the same. Fig. 3, isan enlar ed detail sectional elevation of the mova 1e segmental type carrier showing mechanism for adjusting t e type shifting block. -Fig. 4, is an enlarged side elevation of a type arm, with the type. Fig. 5, is an enlargedplan 0f the central-part of the type carrier.

Similar letters refer to similar parts throughout the several views.

.In the drawing the frame work of the machine is indicated by A, and is stationary.

B, is the impression surface or roller mounted on the movable carrier O, which is adapted to slide on the horizontal rails D .of the frame A.

E, is the segmental carrier to which the type arms are fulcrumed, and is mounted on type arms J, as shown.

being hinged to the transverse bar a of the frame A, and the lower end of the arm H, is hinged to a centrally located lug 2, of the frame. The arms F, and H, support the segmental carrier E, and move in parallel order to bring the carrier E on a level plane toward the impression surface B, and at right angle thereto. The segmental series of type arms J, are fulcrumed to the segmental wire K, which is secured in the carrier E, which moves at right angle to the impression surface. The opposite ends of the type arms J, are provided with the type P, which are adjustably secured to ,the type arms, by means of a tapered shank 3, on t type, said shanks fitting in the sockets 4, of t e arms, and secured thereto by nuts or screws 5.

The face of the type are convexed and of a circle whose center 1s the segmental fulcrum 'wire K, to which the ty e arms are fulcrumed. The shanks 3 o the type, are a continuation of the type, and have shoulders 3,'to fit on the sockets 4. A central type .arm is shown hanging downward in Fig. 1. of

the drawing, and at rest.

The series of keys M, are fulcrumed at N, to the machine, and are held to the fulcrum by the suspension springs 6, which connect said keys, and the bracket 7, of the frame together, the opposite end parts of the ke s M eing held in rest dposition by means 0 the rods R, connecte thereto, and to upper cranks T.

e end of the The carrier E, has an outer segmental fulcrum wire S, similar to the fulcrum wlre K,

and a series of cranks T are hung on the wire S, and the aforesaid rods R, and pivotally connect the cranks T, and the keys'M, together. Links U, are pivotally connected to the opposite ends of the cranks T, and to the A slot 8 is necessary in the type arm, at the connection of the lin U, with the arms for operative purposes and to allow the carrier E to arrive at ts predetermined place.

The central art of the segmental carna e E, has a shift b opening, or recess X, to receive the type P, in

look V, with a central gui e said recess. The recess X is shaped in a maning.

ner to conform to the sides and to the rear part of the type, and is positive. The block V, has an upper flange, or projection V to retain the block in lower position in the carrier, as shown.

When a key M, is depressed, the type P, enters the recess X in the shift block V. Between the hinges a and 2, of the arms F, and H, is a transverse bar "W, to which the vertical rod 9 is connected, and a lever 10, is pivotally connected to the upper end of the rod 9. The opposite end of the lever is pivotally connected to the link 12 which is hinged at 13, to the wall A, of the frame. The lever 10, has an upper arm 14, to which is pivotally connected a needle 15, and the opposite end of the needle enters into a hole 16 inthe shift block V, and the point of the needle enters one of the needle point holes 17 shown in broken lines in Fig. 4 of the dr2fwing, in the rear of the type P, when the type is in position in the recess X of the block V, for writing. The lever 10 is fulcrumed to the lug 18, of the carrier E.

When the rod 9 is brought downward by the depression of a key M, on the transverse bar W, the lever 10, and the link 12, come in line with each other, consequently the carrier E, on the arms F, and H, is carried toward the platen B, and at the same time the type arm J, is brought to position and the type P, enters the recess X of the block V, and the needle on the arm 14 enters a hole 16 in the block V, and locks it and also enters the needle point hole 17, in the type, to lock the type, and at the same time to print against the im ression surface.

20, is a shift bloc key, at one side of the key board, and is fulcrumed at 21, to the side of the frame A, and is held at tension by the spring 6 which is hung from the bracket 7. A small lever 22 is fulcrumed at 23 to the carrier E, and one end of the lever 22 is pivotally connected to a'connecting rod 24, and the opposite end of the lever 22 is ivotally connected to a lug 25 depending om the ortion V of the shift block V as shown in ig. 3. The lever 22 operates in a slot 30 in the carrier E, shown in Fig. 5, of the draw- Thelower end of the rod 24, is pivotally connected to an arm 25, which is centrally located, and a similar arm 25 is provided, the arms being disposed at a distance apart from each other and both arms 25 secured to a loosely mounted transverse rod 26. central arm 25, the rod 24 is connected, and to a similar arm 25, the rod 28 is connected, and the lower end of the rod 28 connects with a key 20.-

When the key 20 is depressed, the block V, in the center of the carrier E, is shifted upward until the lower hole 16in the block V is osite to the needle 15 cushion 38 is disposed beneath the arms To the M and 20 in the frame A, to receive the impact of the arms and thus insure an equal de- Upon the depression of a key M, a rod R is brought downward, consequently the crank T, and the link U raises the type arms J, together with the type P on the broken arc line 32, as shown in Fig. 1 of the drawing. Immediately after the type P has entered the one common and central recess point X in the block V, the rod 9 is brought downward by means of the key which presses on the transverse bar thereby causing the lever 10 and the link 12 to be brought into alinement with each other, consequently the arm 14 of said lever 10 propels the needle 15 through the hole 16 in the block V, and the point of the needle into the opening 17 which conforms to. this needle point. At the same depression of the key, the segmental carrier E on the three hinged arms F, F, and H, is brought toward the platen B by means of the alinement of the lever 10 and the link 12 forwarding the lug 18, hence also forwards the carrier E, of which said lug forms a part, to a predetermined lace.

It will be noticed that all the type J ente the block V, in writing order as one common center, which is the center of the fulcrum wire K of the type arms J, and that each type P is adjusted in the socket 4 of the arms, in order that the type shall all be in the same direction, that is, opposite to the platen or impression surface B. The lower end/of the opening, or recess X, in the shift block V, is of sufficient size to allow the type of all the arms J, to freely enter the recess X. Each type is minutely adjusted and set in its socket 4 and held by the screw, or nut 5 on the end of the shank of the.typ'e.

It will be obvious that the type arms J, the carrier E, together with the type locking needle 15, are all moved together to perform their separate functions by one depression of any one of the series of typewriting keys, and that the carrier E moves at right angle to the impression surface.
