TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 764,935, dated July 12, 1904.

Application filed April 14, 1904.

To Ml whom it may concern.-

Be it known that I, J ACOB FELBEL, acitizen of theUnited States, and aresident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to type-writing machines, and has for its object to provide such machines with atype-action in which the bearings of the type-bars are protected from dust and falling dirt.

My invention is applicable to any sort of type-writing machines in which type-bars are employed, but more especially to front-strike machines, because in them the type-bars are pivoted below the platen and their bearings are in the path of dirt falling from the platen when erasures are made.

My invention consists in certain parts, features of construction, and combinations of devices, which will be full y set forth herein and particularly pointed out in the claims.

In the accompanying drawings I have shown my invention applied to a Monarch typewriter.

In said drawings, Figure 1 is aview in vertical longitudinal section of so much of a typewriting machine as is necessary to illustrate my invention. Fig. 2 is a perspective view of the heel or pivotal end of atype-bar. Fig. 3 is a perspective view of one end ofa link which operates a type-bar; and Fig. 1 is a rear view of the segment on which the type-bars are mounted, the operating-links being shown in section on the line w w of Fig. 1.

Referring to the drawings, 1 designates the frame of the machine. The key-levers 2 are pivoted on a rod 3 and are pressed upward by springs 1, secured to a cross-bar 5. Suble-. vers 6 are pivoted at 7 to the key-levers 2, below which is mounted a fixed rod 8, which passes through slots 9, formed in the lower portions of the several sublevers 6. The construction is such that when a key-lever is depressed the upper end of its sublever is moved toward the back of the machine. Each of the type-bars 10 carries at its free end a type- Serial No. 208,216. (No model.)

head having two types 11 and 12, and all of said type-bars are pivotally mounted on a segment 13 in such manner that when any of them is operated the type 11 will strike the platen 14 at the printing-point, which is on the front face of the platen. The segment 13 is adapted to be elevated to cause the type 12 to strike the platen by means of a case-shift device, which is not here shown. The free ends of the type-bars normally rest on a segmental pad 15, which is supported by rods 16, projecting forward from the segment 13. Said segment 13 has cut in the front face thereof a series of substantially radial slots 17, in each of which is mounted a type-bar hanger 18. Each of the slots 17 is formed with a threaded round hole of a diameter greater than the width of the slot, and into this hole is passed a set-screw 19, the end of which engages the hanger and retains it in place. The heel of the type-bar is bifurcated or formed with a slot, as shown at 20 in Fig. 2, to receive the projecting end of the hanger 18, to which it is pivoted, as by a pivot-pin 21, which passes through a hole 22 in the typebar and a corresponding hole in the hanger. The walls of the slot 20 and the flat surfaces of the hanger 18 are side bearing-surfaces which guide the type-bar as it swings about its pivot 21.

Each of the type-bars 10 is formed on its upper side with an car 23, which is provided with a pivot-pin 24, the ends of which project into, openings 25 in jaws 26 and 27 of a typebar-operating link 28, the rear end of which is pivoted at 29 to the sublever 6. This pivotpin 2 1 is above and forward of the pivot 21 of thetype-bar. The links 28 are provided with or are so formed and arranged as to constitute hoods or covers adapted to shield the bearings of the type-bars from falling dirt. To this end a part 30 of each link extends across the space between the jaws 26 and 27, and at that part of the link which lies over the bearings the jaws are preferably spread apart and widened in the direction of the segment, forming on each side of the link a sort of apron, as shown at 31.

In machines of the kind herein described as usually constructed the type bars are not spaced uniform distances apart, but are graduated in this respect, the distances between successive type-bars being least in the case of those bars near the center of the segment and greatest in those near the ends of the segment, as shown in Fig. 4. The different bearings obviously stand at different angles, and the several type-bars are pivoted to swing in different planes, having different inclinations to the vertical. As shown in Fig.4, the several links are slightly modified in accordance with the differences in the arrangement of their respective type-bars. In those cases where the type-bar bearings are inclined to the vertical and where the distances between successive type-bars are great enough to allow of such construction the aprons 31 extend past the upper edges of the type-bars and a short distance down their sides; but near the center of the segment, where the bearings are nearly vertical and where the bars stand close together, the aprons 31 are narrower and lesswidely spread, and their lower edges may stand over the upper edges of the forks of the type-bars. In each link the aprons are spread as widely apart as the spacing of the type-bars will admit of or as is necessary in order that a part of the link or cover may lie vertically over the bearing, so as to catch and deflect any falling dirt which might otherwise find its way into the bearing. It will be observed that the link protects not only the typebar bearing, but also its own pivotal connection with the type-bar.

As shown in the drawings, each of the links 28 is made of two pieces, the forward one consisting of sheet metal bent into an inverted-U shape, the top of the U forming a roof and the sides of the U forming the jaws 26 and 27 and the aprons 31. The metal is split back from the end, as shown at 32, so as to allow of the jaws being sprung apart to clear the end of the pin 24: to connect or to disconnect the joint between the link and the type-bar in assembling the machine or making repairs. The rear end of the sheet-metal piece is bent into a tube 33, Fig. 3, and into this tube the rear end piece of the link is threaded. This screw connection affords an adjustment of the link as to length and also allows the forward end of each link to be turned to an angle to correspond to that of its type-bar, which is important, inasmuch as the type-bars all lie at different angles.

So far as I am aware it is broadly new to utilize any type-bar-opcrating member as a means for protecting the type-bar bearing from dirt. It is also broadly new to provide each type-bar with any sort of individual movable dust-guard for its bearing, which dust-guard is not part of the type-bar itself.

Various changes and modifications may be made without departing from the gist of my invention.
