O. PETERMANN. TYPE WRITING MAGHINE APPLIOATIOK FILED SEPT. 13, 1913.

a 3 Wm wtoz -3 55a PeiEe/mann 13 Luqbtozme 1 4 I member 22 has a plate-like body with feet 2% at an angle thereto in which are openings Screws 26 have their bodies passing through the openings 25 and serve to rigidly hold the hangers to the supporting plate 11 of the frame. The hanger member 22 is provided with an annular rib 27 formed by depressing a portion of the body thereof, and resting directly against said rib is an annular rib 28 of the type-bar 16. The typebar 16 has an enlarged head or boss 29 and may also have its rib 28 formed by depressing a part of the head 29' in the manner shown. The type-bar has its rib 28 opposed to the rib 27 so as to form an annular space or chamber 30 in which a suitable lubricant may be placed if desired, and said type-bar has its head located in the space 31 formed between the hanger members 22 and 23. By providing the ribs a large substantial hearing surface with little friction is provided, and said bearing surface may be readily ground to provide suitable surfaces instead of grinding the entire faces of the hanger member and the type-bar head.
The member or strap 23 of the hanger may be made of lighter metal than the member 22 and may be of spring material and has one end, as 32, provided for an aperture through which passes the body of the 'screw 33, in order that said member 23 may be held to the member The member 23 at the end may als be provided with depressed parts, as 3 t, forming dowel pins which are adapted to enter recesses 34 in the member to assist in holding the member 23 against swinging movement and in proper position relative to the member 22. This member 23 is offset at to provide the space 31 for the type-bar hos and has a vertical portion from which my be depressed a substantially scmi spherical member or body 37. The body 37 is located at the free end of the member and performs the same function as a ball pivot except that it is immovable in a rotary direction, and said body 37 is adapted to be seated in a conical or cup-shaped recess or opening 38 formed in the type-bar head or boss 29. The recess or opening 38 tapers from the outside of the type-bar inward and is so arranged with respect to the member 37 that a hearing or pivot for the type-bar is provided at one point and that on the side opposite the member 22 of the hanger or support. A screw 39 has its stem portion passing through a central aperture of the pivot or integral bearing body 37 and engages a threaded aperture in the member 22, said screw and body 37 being substantially central of the boss or head 29 of the type-bar. The screw 39 has a slotted hexagonal head tov adapt the same to be adjusted by either a wrench or a screw-driver. The screw 39 is normally held under tension by reason of the spring action of the member 23, and in addition to this tension or independent thereof the said screw may-be held at its threaded end where it engages the threaded opening in the member 22. A slot 40 may extend on opposite sides of the threaded opening for the screw, and a part of the member 22 may be cut away at one side of said opening, as at ll, to form a yielding part or finger 42. This yielding part will keep the screw under tension and prevent the same from becoming loose, while the machine .is in use, and further the original tight fit of the screw will be maintained. 'By rotating the screw the member 23 may be forced toward the member 22, and will carry the type-bar therewith in order that the wear may be taken up in case it occurs and the type-bar forced properly against the hanger member 22.
It will be evident that by providing a hanger or a support in which a single pivot is provided for each type-bar and in which the pivot portion is forced in the direction of wear by means located at the pivot, all liability of the type-bar to twist when operating the machine which may cause unevenness in the alinement is overcome; that the ribs form means providing a substantial bearing; that said hanger or support is simple in construction and may be made by stamping the same from sheet metal; and that effective means is provided whereby the operating surface between the hanger and the type-bar may be properly lubricated.
Having thus described my invention I claim as new and desire to secure by Letters Patent 1. The combination of a. plate-like hanger member having means for securing the same to a support and having an annular rib on one side thereof, a plate-like spring member secured at one end to the. first-mentioned member and offset therefrom and provided with an integral cup-shaped body forming a bearing, a type-bar having. an annular rib on one side bearing directly. againstthe rib of the first-mentioned member and having a tapering opening receiving the body of the spring member, and a screw passing cenbody of the spring member, and the typebar, and held to the first-mentioned hanger member for adjusting the plate-like spring member and bearing portion in the direction of wear.
