Specification of Letters Patent.
Application led June 5. 1908, Serial 110.436,74?. Renewed .Tune 5, 1913. Serial No. 772,002.
To all whom it may concern:
Be it known that I, NILS H. ANDERSON,
a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Type-lVrit.- in;l Machines, of which the following 1s a full, clear, and exact description, such as `will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to typewriting machines, and more particularly to the carriage feeding mechanism thereof.
One of the objects of the present invention is to provide `new and improved means for effecting a connection between the escape ment mechanism and a feed-rack of the platen carriage.
Another object is to provide mechanism of the above character which will be. substantially niseless in operation, and wherein friction between moving parts will be reduced to a minimum.
vOther objects will be in part obvious and in part pointed out hereinafter.
` The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.
In the accompanying drawings, wherein is illustrated one of the various possible embodiments of my invention, Figure 1 is a view taken transversely through the ma'- chine, the mechanism constituting the present invention being shown in elevation; Fig. 2 is a sectional view upon an enlarged scale, taken through portions of the escapement shaft and the associated part-s of the mechanism; Fig. 3 is a similar view of the upper portion of the mechanism illustrated in Fi 2, but looking in a direction at right angles thereto, the platen carriage being shown in a shifted position; Fig. 4 is a view in plan of the mechanism shown in Fig. 3; Fig. l is a plan view showingr a portion of the feedrack and the feed-pinion; Fig. 6 is a sectional view on an enlarged scale, taken on line 6*-6, Fig. 2; Fig. 7 is a similar view on` feed-pinion.
Similar reference characters refer to similar parts throughout the several figures of the drawings.
Referring now to the drawings, 1 denotes a portion of the framing of the machine, and .Q denotes bed or table upon which the typebars, one of which is shown at 3, are supported and across which they are projected to impression by actuating mechanism not shown herein.
4 indicates the platen frame which carries the paper roll 5. The platen, which, in the present instance, is comprised by a thin strip of metal 6, lies in Contact with the platen roll. The pla-ten carriage, in the present instance, is povidedwith a pair of longitudinally extending rails 8 and l0, provided with ball runways,',a`nd between those rails is located a shift rail 1 1 which is su]' ported at its ends by means of links, one of which is shown at 12, said links being in turn connected at their lower portions with arms 13. extending from a shift shaft 14. Balls 15 are interposed between the shift rail and the. rails S and 10 of the platen carriage. the construction being such that during the letteihfeeding movements of the Patented J an. 13, 1914. I
longitudinally moving part of the platen carriage'said rails will ride upon rail 11,
and the entire platen carriage will be shifted vertically upward or downward from a normal intermediate position when said rail 11 is actuated hy the shift mechanism which, in the interest of clearness of illustration, is not shown herein. It should be understood, however. that when shift. shaft 14 isrotated in opposite directions the platen carriage will be correspondingly shifted through its connections therewith.
1G indicates a tie-rod which extends transversely through the central portion of the machine and has an upwardly extending portion or horn 17 which forms an abutment for the platen carriage and holds the same against recession wher the platen isengaged 'by the types. The intermediate portion of the tie-rod rests upon a taule or bed 18 wliieh is lined in the framework et the machine, and the rear portion et said tie-rod may be moved backward or forward to change the disposition of the platen 'with respect to the faces ot the types by means ot a threaded screw 2() which forms a portion of the tierod and which is threadedly connected to the rea-r portion, as at 2l, the opposite endo'f said rod beingr anchored in thevliront Wall 22 of' the framing' of the machine and is provided with an operating handle 23. It is believed that the' above brief description of this tie-rod mechanism 'will sui'lice to render the object-s of the present invention clear ot understandinej. This mechanism, moreover, is described. and claimed in the United States Letters Patent .to lill. l?. Kidder and C. lV. Sponsel, No. 879,107, February l1, 1908. 1t
will be understood that the relatively movable parts of the'tie-rod may be manipulated to cause the platen carriage to move forward or backward with respect to the faces of the types.A
The escapement devices, comprising a fixed dog1 211 and a, movable dog are shown mounted upon a rocher ifnember 2G -which is adapted to be actuated by means oit an arm 37 and a link 28, the latter of which is connected with the arm 30 extending from the universal roch shaft 3l., said shat't being` in turn actuated by means oli arms and links, shown at and d3, respectively, the .links supporting a universal bar 34-, upon which the hey levers rest.
The mechanism above described forms no part of my present invention, but it has been described in order to render the objects hereof clearer oi anderstandinp.
Referring now to the escapement mechanism, indicates the esca pement wheel. 'with which the escapement devices cooperate to aii'ord a. feed ot the carriage, said escape-` ment wheel. resting', as usual, against the nuwable dog' The hub 3G ot escapement wheel in the present instance7 isprovided, as at 37 and 3l", with ball-runways, one of 'these runways being provided at either side ot the escapement wheel. llflfelnbers #it-.0 and il threaded .in brackets 4Q and 4:3 extending' :trom lined portion oit the framing of the machine, as at dit, support the eseapement wheel and the associated parts through the interposition of balls l5 and do, respectively, which located in runways and 3&5. dt this point, it may be noted that the ball-runways and 3S are so formed as to constitute Zones oit a sphere the center of which is located at upon the central axis of the escapement wheel midway between the planes of the sides thereof. lllembers l0 and Llll, therefore,`
manners constitute a universal bearing for said escapement wheel and prevent any binding between. the engaging parts of the bearin in whatever position the escapement whee may assume. In other words, the escapement wheel can rotate as well as oscillate in its bearings.
The escapement shaft shown at 48 is eX- tended through the hub of the escapement wheel and is supported therein by means of ay shoulder 50 which rests upon a shoulderl formed within said hub. The lower end of the escapement shaft, in the present instance, is provided with a tln'eaoled pin 52 which receives a collar 53 and a nut 54, this construction preventing a relative longitudinal movement between the escapement wheel and the shaft. The upper portion of the hub 55 'of th escapenient wheel is provided with a plurality oit teeth 5G and cooperating with these teeth is a member 57 located upon the es eapement shaft, which has oppositely disposed tee'th 58 which interfit with the teeth 56 formed upon the hub. Member 57 is allowed a slight sliding movement upon the escapement shaft, and the teeth thereof are held in engagement with the teeth oit the hub portion by means of a spring (i0 interposed between said member and a collar 6l,
keyed as at (32 upon the escapement shaft. A hey G3 is extended loosely through an aperture provided in the escapement shaft and prevents relative rotation between the clutch member 57 and said escapement shaft, a hood (Saldaeiug provided to prevent the escape ot the loose key (5?). From the above description7 it will'be understood that when the escapement wheel is rotated in one direc- "tion, the intertitting teeth upon the hub oi the eseapement wheel and t-he clutch member 57 will compel a rotation of the escapement wheel with said escapeinent shaft, but during' a reverse rotation ol the eseapement sliatt, the teeth 5(3 and 5S will merely ride over each other, whereby the cscapement wheel may remain stationary.
Referring now to the feed mechanism, a feed-pinion G5 is carried upon the upper 'end ot the escapement shaft LS and meshes with the feed raclr which is swiveled upon the platen carriage so as to enable it to be swung upward and thereby dis- .i6 provided,l said retainer bein grbved depending hub portion 73, thev oo ves thereofbemg best shown at 74 in ig. 6 of the drawings, and the escapement shaft 48 is provided with correspondingly '5 located grooves 75. Located in grooves 74 and 75 of the hub portion 73 of the feedpinion and the escapement shaft 48, respectively, are balls 76, said balls operating as keys to prevent any relative .rot-ation be- 10 `tween the.feedpinion and the escapement- Shaft, but permitting the feed-pinion to :slide freely upon saidy shaft. In order to retain the balls in position in their proper places within their grooves, a retainer 77 is notched at its upper portion, each notci thereof receiving one of balls 76, and a spring 78 which rests upon collar 61 of the escapement 'shaft .48, and is attached thereto, is, at its upper end, connected with said retainer and ho ds the same in operative position.' A hood 80 pressed upon the hub portion 73 of the feed-pinion and depending therefrom has a shoulder 81 which is adapted to en- '25 Ego retainer 77 and prevent the same from ing carried out of operative position. Ilxtenclingl forwardly from the shiftable rail 11 of t e platen carriage are arms 82 in which are threaded trunnion screws 83, upon the inner ends of .which is journaled a circularhead 84.' This head is'provided internallywith a grooveor-ball-runway 85, andthe hub 73 of the feed-.pinion is provided with an oppositely'located and simi- 36 larly formed runway 86,'balls 87 being provided between said runways.
Having .thus described the construction of this embodiment of my invention, the operation thereof may now be explained: it
40 will be understood that'during theoperation of the Vmachine.theescapement devices coperating with the escapernent wheel will afford a feed of the carriage in the usual manner. When the carriage is returned by 45 the hand ofthe operator to a new line-commencing position, the spring-controlled clutch constituted by the toothed member 57 andthe teeth provided upon the hub of the escapementwheel, will be automatically disengaged, whereby the escapement shaft may be rotated freely in a reverse direction without com elling a. rotation of the escapement wheel w rich will be allowed to remain stationary' in'engagement with the escapementV devices. 'Whenever the platen carriage is shifted for different case printing, the feedpinion being-supported thereby will move therewith and slide upward or downward on' the escapement shaft, and during this op` 60. eration the ball key -members will o era-te to eliminated any friction .betweenit e feedpinion-'and' saidnshaft. When it is. desired to changegthe disposition of the platen with respect. to'thevfaoes of the types, such op- 65 Alengthening ori shortening the tie-rod through a manipulation of rod 20, as above explained,4and during this operation the feed-pinion will be carried forward or backward, thereby tilting the escapement shaft and causing the escapement wheel to oscillate slightly in its spherically formed supporting bearing, It will accordingly be seen that I have provided mechanism well adapted to attain the above, among other, ends in a. simple, yet efficient manner, and which will operate toremove any chance of binding in the bearingsfor the escapement wheel or the feedpinion when the platen carriage is moved toward or from the faces of thetypes or is shifted for 'different case printing. .The feed-pinion being supported upon the platen carriageis always in mesh with the feedrack and is shiftable' therewith when the platen carriage i`s shifted.
