Tovall `'whom 'it may concern: y

ABe it known that I, CHARLES P. Mosman, citizenl of the United States, and resident of the borough of Brooklyn, city ofNow York,

in the county of Kings and State ofNew York, have invented certain new and useful Improvements 1n Type-1V r1" :ng Maclunes,

' ofwhich the following is a specification. My invention relates to typewriting ma chilies and more particularly to carriage supporting means, and the 'main object of said invention is to-provide simple and ellicicnt meansof'the character specified by which but little resistance is offered tothe travel of the carriage and by which the carriage will Abe firmly guided in its travel.

To the above and other ends my invention `.consists 'in the features of construction, ar-

rangements of parts and combinations of def vices to be hereinafter'described and particularly pointed out in the appended clanns.

In the accompanying drawings wherein like 4reference characters indicate correspondin" parts in the various views, Figure 1 1s a tragmentary vertical sectional view showing the upper portion of a typewritng machine embodying 'my invent-ion. F ig. 2 is a vertical transverse sectional view of the same taken on the line :n-x'of Fig. 1 and lool'ing,lr in the direction of the arrow at said line. Fig. 3 is a transversesectional view taken centrally through one of the pinions, to be hereinafter' more fully described.

The top plate 1 of the machine is supported `on corner posts 2, and has upwardly and forwardly extending lugs or supports .3 thereon. A guide'rod 1 is detachably seto the lugs 3 by screws The guide rod 11 has .i-nclinedvtracks or liat bearing faces G formed on opposite sides of the top thereof.. These tracks (i are preferably formed by groovin'nr the guide rod longitadinally te form flat faces which 4are inclined a-t an angle to each other as indi-cated -i-n Fig. L The low-er side of the rod has a groove '7 thexeil-l which extends longitud'i- .nally of the rod th'ronghont, or'substantially thrmmhoat, the length thereof. A rack '8 Vis firmly seated -i-n said groove; the teeth of the rack extending beyond the periphery of guide at thelowver side of the latter. The, ide rod on opposite sides of the rack 8 Vis formed 'with flat t: es 9' which constitute tracks against which peripheral bearings 10 .on .pinions 11 are adapted to bear for purso|nrrator 25 in the travel of `the czar-ria poses whichV will hereinafter more clearly appear.- l

T lle-carriage proper may be of any snitable construction, but as shown in the pres* ent instance comprises end. bars 12 havino bearing openings for a shaft 13, on whie a cylindrical platen 14 ismounted. The end bars 12 of the carriage are 'united by a forwardcross bar 15, provided with an ant'b friction roller 16 received betweenl fixed guide rails 17 and 18 secured to the top plate of the machine. The end bars 12 of the carriage are connected at the rear ends thereof by a'bearing member, designated as a. whole by the reference numeral 19. This bearing member is in the, nature of a sleeve which surrounds the guide rod 4, and is provided at the rearslde thereof with Iongitudinally extending cut-outs or slots 20; These slots extend inwardly in op site dif rections from the ends of the bearln member and each slot terminates at 21 be on the middle of thebeari-ng n'nanl'ner' is so as to provide a central connecting web 22'. Thus a connection 1s formedbetween the lip; per and lower portions-of the bearing member at the rear'as well as 'at the front thereof. By arranging the slots 20 in the manner shown, they are adapted to receive the forwardly; extending portions of 'supports 3, as indicated in Fig. 2, and to ai ford a free movement of the ends of the bearing member past said Vsap-[mits in the travel of the carriage from side to side of the machine.

The bearing;r member 19' provided with inclined tracks or bearing and is itself surrounded by the bearing member 1'9. Rectangular openings 26 am formed near cach end yof lthe sleeve-like separator for the reception of the anti-friction- 4rollers 24. lt will thtnfefore understood that the anti-friction rnllersrare maintained properly positioned and .separatedby the from side lo side of the machine.

In-order to always maintain a definite relation between the rollerl separator and the carriage, and consequently between the' anti-friction rollers and the carnage, I have vprovided means which will now be described. A

Depending ears 27 are-formed on the sep.- arator-'near each end thereof. A pivot pm 28 extends through openings in each set of the ears 27' and constitutes a ivot for aK pinion 11 hereinbefore referre t o. Tins pinion. is preferably formed, as indicated 1n Fig. 3, of a central disk'29, provided with peripheral teeth A30. Disks 31 are arranged on op osite sides of the disk' 29 and are (l) thereto by rivets 32, so as to unlte the three disks to constitute a single combination pinion andbearing roller. The disks 3l are provided wlth peripheral bearmgs 10, as herelnbefore pointed out. These bearmgs are adapted to co-act with the tracks 9 on the guide rod 4, whereas the teeth of the pinion mesh 'with the -rack 8 secured to-the guide rod. A late-likeJ member or support 33 extends ongitudinally of the be'arlng member beneath the same and throughout, or substantially throughout, the length of said bearing member. The platelike sup-A port 33 is provided near each end thereof with screws 34 and 35 on opposite sides of the center of said plate. The screws 34 are received in tapped openings in the bearing plate and bear at their upper ends against inwardly directed flanges 36 on the bearing member. On the other hand, the screws 35 extend freely through o eninefs in the plate 33, on opposite sides o the laongitudinal' center thereof, and are received in tapped openings in the inwardly extending flanges 36 on the bearing member. By this construction each end of the bearin plate 33 is provided with independent adjusting means by which it may be raised or lowered and tixedly maintained in its adjusted osition on the bearing member of the carriage.

hus, by loosening the screws 34 and tightching the screws 35 the bearing 'plate 33 will be elevated or adjusted toward the. bearing member on the carriage, whereas when the screws 35 are loosened and the screws 34 tightened the bearing plate 33 will be lowered. The bearing plate 33 has a central longitudinally 37 therein, which preferably extends throughout the length of the 'bearing plate. Thisl longitudinally extending groove, or pocket, formed in t e bearing plate is adapted to receive a rack 3 8 which coperates with the pinions`11. Near each end of the bearing plate 33 is a tapped opening in the bottom thereof to receive a screw 39 which extends, through the tapped opening, and bears at its upper end against the bottom of the rack 38 to effect a vertical adjustment of, said rack. It will therefore be understood .ber' on the carriage.

.to side of' they machine. Any

extending groove that the screws 39 constitute Aindividual adjusting means at opposite ends of the rack 38, whereby arela-tive adjustment between the racks 38 and 8 maybe effected. Longitudinally extending tracks 40 are formed on the bearing plate 33v on opposite sides of the rack 38. These longitudmall extendthroughout, or. substantially throughout, t-he length of the bearing plate 3 3 and are adapted to coperate with the peripheral bearings 10 on the' pinions 1.1. The peripheral bearings 10 will' therefore be enga ed on opposite sides by the tracks 9 of the guide rod and the tracks 40 of the bearing mem- The roller. separator 25 will thus be supported by the roller bearings 10 between said tracks 9 and 4 0, to maintain the separator out of contact with the guide rod 4, and to maintain it in proper position out of contact with the bearingzmember 19 on the carriage. At the same timethe .eripheral bearings 10 prevent anupward isplaeement of the bearing member 19 relatively to the fixed guide rod' 4. The adjusting- screws 34, 35 and 39 constitute means by which a nice lrelative adjustment between the, parts may .be effected, to compensate for wear; to maintain the parts in the proper relative positions; and to take up any lost motion, so that the carriage may be firmly guided in its movement from ,side tendency of fore and aft or downward displacement is overcome or resisted by the anti-friction rollers 24, whereas the upward thrust of the bearing member 19 is resisted by the peripheral bearing members 10.

It will be observed that the pitch line of each of the pinons 1l is about coincident with the companion peripheral bearings 10 so that the surface speed of the pinion aud bearing members is the same.

lt will be understood that the travel of the roller separator and each of the anti friction rollers 24 is equal to one-half the extent of travel of the'carriage, and that this relation is constantly maintained by the engagementof the pinions with the oppositely disposed racks on the fixed guide rod and on the bearing member 19, which e'ngage the pinions on opposite sides. The relation of the parts is such that when the earriage is centrally maintained on the frame of the machine, the anti-friction rollers and the separator 25 will likewise be centrally positioned with reference to the frame of the machine and the carriage.A Then the carringe travels in either direction theantifriction rollers and separator will travel in the same direction one-half the distance traveled by the carriage, as indicated in Fig. 2. Various'ehanges may be made without departing fromthe spirit and scope of my invention. i.
