TYPEWRITING MACHINE.

Application filed December 1, 1924. Serial No. 753,112.

To all whom it may concern:

Be it known that I, EDWIN E. BARNEY, citizen of the United States, and resident of New Rochelle, in the county of lVestchester and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to shielding and protecting means for aportable typewriting machine in which parts are shifted from a compact toan expanded position for use.

The main object of my invention, generally stated, is to provide inexpensive and highly efficient means of the character specified.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangement of parts, and combinations of devices set forth in the following description and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the differentviews,

Figure 1 is a fragmentary fore-and-aft vertical sectional view with parts omitted,

of a Remington portable typewriting'machine embodying my invention; the section being taken about centrally through the machine with the carriage shown shifted to the right.

Figure 2 is a detail fragmentary elevation of one of the type bar shields or guards and the companion end type bar; the view illustrating the parts as they appear when seen from the direction of the arrow in Fig. 4 with the shield and type bar expanded in position for use.

Figure 3 is a fragmentary detail vertical sectional view showing the type bar shifting member lowered and parts associated with said member.

Figure 1 is a detail top plan view of a portion of the machine showing the type bar shields and type bars in compact position ready for inclosure within the usual carrying case.

I have shown my invention embodied in the present instance in a Remington portable machine in which the invention may be readily incorporated with but little change in the existing structure of said machine.

t should be understood, however, that the invention is not confined to embodiment in such machine.

In the Remington portable machine, printing key levers 1 are fulcrumed at 2 and are received in an inner frame 3 surrounded by an outer sheet metal frame 4. Each key lever 1 is operatively connected through a link 5, sub-lever 6, link 7, sub-lever 8 andintermeshing gear segments 9 and 10 with the associated type bar 11. The type bars are all pivoted on a pivot wire 12 to strike downwardly from their upright position for use against the top of a platen 13. The platen is mounted on the carriage 14 in the usual manner to travel from side to side of the machine.

Type bars are adapted to be simultaneously turned on their pivots from a compact, recumbent, substantially horizontally disposed position, shown in Fig. 3, to an upright expanded position for use, indicated in Fig. 1. The means employed to control these pivotal movements of, the type bars to and from expanded position comprises a finger piece 15 extending to the outside of the machine and carried by a crank arm 16. This crank arm is secured to a rock shaft 17 which extends acrossthe machine and is mounted at its ends in bearing openings in the. inner frame 3. Two additional crank arms 18 are fixed to the rock shaft and are pivoted to links 19 which in turn are pivoted, at 19 at their upper'ends to bracket cars 20 fixed to a plate-like member 21 by which the type bars are elevated and loweredv around their pivots. This member. 21 may be made of sheet metal and is in the nature of a cover plate and type bar rest carrying a felt pad '22 against which the type bars bear in both expanded and compact positions. The member 21 carries depending substantially vertically disposed arms 23 at opposite sides thereof, said arms working in grooved guide-ways in fixed upright guide members 24. In this manner themember 21 is supported and guided for vertical movement when the rock shaft 17 is turned by thefinger piece 15.

In accorda-ncewith my present invention, the forward edge 25 of the memberv 21 is curved and extends beyond the free ends of the type bars and adjacent to a correspond. ingly rear curvededge 26 of a top plate 27 secured to the machine frame. The forward curved edge of the member 21 is provided with a depending vertically arranged flange or apron 21 located adjacent to the inner curved edge or wall 26 of the top plate 27. When the member 21 is lowered as shown in Fig. 3, the top thereof is located a considerable distance below the highest part of the top plate 27, but is nevertheless surrounded by the curved edge or wall 26 of the top plate. When the member 21 is elevated, as shown in Fig. 1, the lower end of the apron or flange 21 is below the upper edge of the top plate and within and adjacent to the curved wall 26 thereof. It will be understood therefore that the apron '21 at all times substantially closes the space between the member 21 and the top plate 27 and prevents the admission of dust to the underlying actuating connections between the key levers and type bars and other operating parts of the machine. Therefore this member 21 and its flange 21 together with the top plate 27 and the frame of the machine,

incloses and houses many of the working parts of the machine; housing and guarding them against the admission of dust and hiding them from view, this being true whether the type bars are in the compact positionor in the expanded position for use. In the present instance I form the member 21 with a hollow bead 28 concentric with the front curved edge 25, said bead providing for inclosure within its carrying case.

To further aid in protecting working parts of the machine, and in preventing the hands of the operator from coming 1n contact therewith in manipulating the machine, I

use. tive when the type bars are conditioned for have provided additional-guarding or shielding means which will now be described.

-Outside of eachend type bar of the system, I provide a guard or shield that is movable with the typebars in their pivotal movements to and from expanded position for By these means the shields are effecuse, and when the latter are collapsed or moved to compact position said shields will not add anything to the dimensions of the compacted machine, as willnow appear.

In a machine of thejcharacter shown, it is necessary for the operator to reach over the system of type bars, when they are conditioned for use, to effect an adjustment or return movement of the carriage, or to ad just the'paper. :In the present instance I contemplate providing a finger piece 29 by which-the platen may be line spaced and the carriage returned by a single operation, and by a swinging movement of the lefthand of the operator from left to right and slightly forward. For the purpose of my present invention, it is unnecessary to illustrate the means controlled by theline spacing handle. Such means are to form the subject matterof a separate application filed Dec. 22, 1924, Sr. No. 7 57,545. In adjusting or returning the carriage, or adjusting the paper, one or the other or both hands of the operator might come in conflict with the end type bars of the system. Aside from any possibility of injury to, or bending of, the type bars, the hands of the operator may become soiled and possibly scratched or cut on the sharp corners of the type blocksat the ends of the system. Bymy present 1nvention, I overcome this difficulty by providing the type bar guards or shields hereinbefore referred to. Each shield is designated as a whole by thereference numeral 30 and preferably consists of a sheet metal member curved in cross section, especially at the outer end portion thereof so as not to present any sharp corners or edgeswith which the hands of the operator might come in contact. Each shield is pivoted near one end, at 31, to an ear 32 provided on an existing plate 38 secured to the fixed type bar segment M by a screw 35. The pivot 31 of each shield is located adjacent to the pivot V ofthe associated end type bar, as will be seen at the right hand side of A1. This is in order to enable'each shield to swing with its associated end type bar and maintain substantially the same relation thereto inthe recumbent and expanded position of each of said bars. Each shield extends lengthwise of, substantially parallel with and outside of the body portion of its associated type bar. It will be seen that the end type bars of the system flare outwardly at their type-carrying ends, and the outer end portion 36 of each shield is flared tocorrespond to the companion end typebar, and also is curved at 37 to pass over and around the ends of several type bars at the corresponding end of the system.

In order to cause the shields to move in unison with the type bars in their shifting movements to and'from expanded position, I operatively connect the shields with the means by which the type bars are thus shift-- ed. In the present instance this connection is effected byproviding a pin-andslot connection between the. member 21 and each Shlfild. Thus-, a bracket 38 is fixed to the member 21 at each side thereof and carries a shouldered headed screw or pin 39. The shank of each pin passes freely through a slot in and extending longitudinally of the associated shield 30. Therefore, when the member 21 is lowered, the shields 30 will be carried down around their pivots 31 and moved to a compact position corresponding to' the type bars, as shown in Figs. 3 and 4. lVhen the member 21 is elevated, the shields 30 are moved to upright expanded position corresponding to the expanded position of the type bars, to protect the end bars of the system against the hands of the operator colliding therewith and to protect the hands of the operator from being soiled or injured.

In the present instance the arms 20, 23 and 38 are formed integral with a plate d1 riveted atACZ or otherwise secured to the member 21; the rivets 42 also securing the plate 43 for the pad 22 in place.-

From the foregoing description it will be seen that I have provided simple and effective means for protecting working parts of the machine which may readily be embodied in a Remington portable machine without material modification of the existing structure Various changes may be made without departing from the invention as it is defined in the following claims.
