To all-whom may con/cem' Be it. known that SAUL eonson, of 'the 5. county, and State of .New York, have lype-`ili"riters, of which the following is :i full, clear, and exactdescriptione My invention relates to improvements in tu pewriting machines, and titre objectV of my invention is to produce n machine which is comparatively simple and Wliicii lios ports constructed and arranged in sncli. Way that the machine can be inode en exceedingly low price1 end i fact low enough to ft-nsloie it to sold vWL` typewriteis would not 1oe used, te able it to ne also .adapted nineline. v

,f invention is intended to produce n n'm'ciiine llris clisiecr which can t e goed deel hard usage Without getting) ont of repair, and to oovinte the use of levers and n. multiplie'ity of sino-ll parts es much es possible.

ll/ly'invention is further intended to diice s, machine in which the type keys ere in the form of straight, sliding plnngeis, erranged lo @pesato on s cani surface and deliecta convex surface A1eating the type7 so that the type may lie inouglit'into printing position, ll oit which 'will be eeen obviates the use of swinging leversloi' similar parts. g

)dy-invention is further intended lo range the upper and lower cese type and numbers and other merits5 in groups, prefer ably groups ot three, each group ccie spending to one key, and to provide en cosy means of yswinging the type bearing surface so as to bring o desired type of group into position. My invention is further intended to an swinging device which bell-like. character, `and which l. terni the type block, and to airnnge the keys so that they will in the lirst instance swing the block and 'type to approximate position, and then center and steady the type while the actnoli printing is eieeed,

The carriage is also provided with oppositeiy ai-ranged parallel. rollers placed neer the sides of tne which are 16 which ere carriage, and connected by an apron l? so that both turn unison, and the apron is adapted to roll np et tlie ends on the rollers and to'carry 'Doper which is being printed upon. To' iaentete the guiding ot' the peper, the l ieee l" 33355955 ii l1 y 'fine n per inserted from tlie bock, that is,

on 'ie left hand in lj is pushed sugli beneath 'the ribbon rolled up partly on the right hand roller 16 and into tljle snron, sitter which the opposite edge ot' l the is Inserted' beneath the guide rod i9 and roiled up on the second roller 1G.

l rovided with n Wheel l 20 et. the end to facilitate turning it, and e spying 2l which is secured to the can l ringe end'lias a projection 22 to engage cor- I responding holes in the The reni' roller i7 is p steady the roller, these holes being spaced the right distance apart to canse the 'proper spacing when the roller is turned a distance one space. The ribbon 23 extends trans verselt7 of the carriage, and is Wound at the ends on rollers Q4 which are held in suitable brackets or clips 25, and whichv are provided "'tl; tlinnib pieces so that the ribbon may l l l l i3 which run on guide rollers 14, and thesel l l l l i i over two guide 'bars 1Sv and beneath e guide rod i9.

Wheel 20y serves to is perfectly smooth, so that the cup l2 may 'tiel thing is to here the convex printing surte; ersehen "Vlie type arranged on the bottoni of l the type lolocl 27, which is simply u .swinging convex suffice, and the type are un ranged in groups of three shown liest in 8, so that oy turning the type surface, either en upper or lower ease lett r or .ligure or other character een he brought into printing' position. The type block has its face plete 27 or the plete `which. carries the type, secured to e lcollar 28, and the coller is preferubly integral Withlthe henger 29, this bcing in the form of two upwardly extending side pieces. A concave plate 30 which is concentric with the fece of the block 27, is also secured to the collar, and is provided with e, series of holes 3l which receive the center pin. formed on Athe end of the plunger 33, which letter slides in the vertically arranged end rigidguide post 34, the letter extending Well downward into the type bloclro l. here described in detail the construction of the type block 2T, but obviously the essen fece, the centering urrunveinent on the back, and the freely swinging arrangement which will presently loe described, but the detail construction of the parte is of Vcourse innne` terial., f

The guide post ,3J- is supported on e rigid erin which is split et the lower end to clasp the gui-de post, und the two ends Lare h'eld together by e holt or equivalent festening. rlh-e upper end of the erin 35 is securedto the Itop .part 37 of e bracket 38, which is curved upward end rearward from the front of the hase l0 und is preferably of sheet metal.

The centering plunger hasr its upper end provided with a, convex surface 39, the contrex side being uppermost, end the plunger is normally raised hy @spring l@ which is coiled around it .beneath the part 39. rlhis part 3S lies ever the hell-like end 4-1 which is formed on che top ofthe guide post 34 and swing freely on it es if on e universal joint. riThis cup l2 is formed on the inner plate i3 of the cani surface ed, which is provided with e depressed 'center or top hei/'ing e hole therethrough to permit thetype' leysto he pushed downward into und through it, es hereinafter describeds The striking surface 44 forms e part of the type block which swings on the hell 4:1, end the structure is further strengthened by the plete 45 which is attached to the plete e3 end connects `with the henger 29. rlhe particular formation of the type block, however, is immaterial, so long as its general shape and its freely swing ing characteristics are preserved.

Vlie cuni surface est of the type hlocli; is d. in the forni of n convex com lie-vii proxiniutely to the center of the hall 4]., and these keys have the usuel linger pieces lt hich can be marked in the usual Way with characters corresponding to the type on the printing surface of the block 27, The keys i7 nre normally raised by Springs i9 which :irc coiled around them, and they slide through the two guide surfaces 5() and 5l, these being concentrioally arranged, und the latter being,` secured to the plate 52 which is attached to the top of the'hreclret 38, while the guide is supported by posts 53 on the uforesuid plate 52. lAn extra key is arranged in the key henk to shift vthe type block so es to arrange for printing upper cese characters or u number or other desired clinracter. The key 52a has e sleeve 53 itteched to the top of it, Which can he; marked vwith the type characters if desired, and it has u thumb piece or milled plate at the top to enable it to turn readily. It also is provided With e flange 55 having ,sockets 5h therein, which engage the boss 57 on the flange of the part 50, 'so that when the key is turned to twist the type block as presently d described, e socket 56 `will come into engage ment with the boss 57. The loWer'end of the key 5f has :i bit 58 thereon, and when the hoy is depressed and pushed through the slot or hole lla and turned, the hit will come into engagement with the slot 58a in the plate 59 '(see Fig. 6 and also Fig. l) which plate turns in e holding' rim G0 on the under side ofthe part Llei, and hes :dining with the slots 58, holes 6l which are engaged by the pawl 62, this gripping,r suiiieiently to enable the plete 59 and the type block to be 'tilted together, but the parWl Will yield sufficiently to enable the plate 59 to he'turned out of en-,

gsgeinent therewith by a little extra pressure on rotating on the key. The hole .4A-a eccentric to the cam surface 44e, asshown by dotted lines in Fig. 6. Consequently when the key 52 is inserted in the hole 44a und tho plate 59 turned, it shifts the position of the hole with relation to the surface 39 end to the com surface lll, and then when the key 52L is Withdrawn and n regular or type key Ll-T depressed, it will go through the cam surface and onthe plunger top 39 et a little different nngle then it- Would have if the position of the guide hole- Lilla I had not been llG changed, and the type groups :isA shown in Fig. S are in suoli relation that hy shifting the position of the plat-e 59 and the guide hole 44 therein, the Walls of the hole are brought into such ey position that the depres sion of u regular key 'iyill tilt the type block so as to bring-.either 'one of u desired group of three intoprinting position. lt will he seen there-fore, that the hole 44a in the plete 59, end cuni surface Mi, is merely e guidii. device the position of-which can he shifted the lrey 52, und thzit the shifting of this eecentricffill'y Walled hole'seifts -theengle :it

4the arm 35, though obviously the lever 67 at every descending movement of the plun- 'as shown being supported on the bracket vbelow the'teeth 83, the return movement of Y the'pawl causes the spring 81 'to engage ant which a key 47 will act and so accurately adjust the type block. To guide the type block and prevent it froni'lateral displacement, it has a projecting arm l63 o none side (see Fig. 1) which enters the slotted guide rod 6e which is attached to the upper part of the bracket 38. i

In this construction pressure is applied against the under side of the paper in order to print. To provide for this,'a bent 'lever 67 is used (see Fig. 1,) which is pivoted as shown at 68 to the block 69 supported on can he supported in any suitable way, and this lever has a slottedend connecting With a pin 70 which Works in the slot of the post 34 and is attached to the plunger 33, so that ger to cause a character to be printed, the inner end of the lever 6T is depressed and the outer end raised. This outer end connects by ay link 71 and boss 'T2 with a swinging haininer or platen handle '73, which is secured to the oscillating shaft 74, the latte-r 38, rlhis arin or handle 73 extends inward in a practically straight line so as to engage an olf-set on the crank 75 for the purpose of workingthe escapeinent, as pres# ently described, and then the arm 73 is bent downward and inward as shown at 76, the arm extendingthrough a slot 73a (see Fig. S) in the base 10, and the inner end oit' the arm is attached to a hammer or platen 77 which Works through. the slot 77a in the base, and has a striking surface 78, preferably of rubber. but it can be of any suitable material, which striking surface moves upward forcibly against the paper and causes the latter to be pressed 'against the ribbon 'and type. lt will be seen that at every Inoveinentot the key 47 to print, the platen will bethrown up forcibly beneath the paper so that the character is produced on the latter. Obviously the type block could be carried against a stationary platen to produce the print.

The escapeinent,l except lfor the means of working it, is not new, The crank 7 5 is attached to a shaft 7 9 which turns in its support in the bracket 88, and it carries a pawl 8O having on one side a light spring 81, as shown by dotted lines in Fig. 1, and having a central spring' S2 which is adapted to ,reg ister with the teeth 83 or" one 'of' the carriage bars 13. The spring 81 is light so that the carriage'can be pushed backward when desired, and the spring Will permit' the teeth to pass by it, but it holds suliiciently to prevent the carriage from moving' in' the opposite direetion'because the spring abats with the paiv'l 80. VlNhen thepawlis depressed suici'ently to throw the Spring 82 other tooth of the rack and the carriage nieves forwardthe dirrtanee el sad one tooth, thereby making; a letter space. This arrangement is not neuvv in detail. To

struck, a bail 84- is arranged to Contact with the upper side et the pawl 80, and this bail 1s secured at the top to the spacing bar 85 `which is hinged to the outer partof the of the carriage, and the cord runs over suit- .o

able guide pulleys 88 and'89 and connects with the customary forni of spring barrel 90 which is pivoted on the under side of the base 10.

The machine can be easily adjusted to adapt itself to different widths ot' paper by limiting the travel ot'the carriage and this arrangement is shown clearly in l? 2 and L1. On the back of the machine is a fixed plate 91 which has a row of pertorations 92 therein, and abutments 93 are adjustable on the plate 91, each abutment riding on the said plate and having a. flat spring 9st thereon, which spring has near its free end, a pin 95 to engage one of the holes 92; he abutment plates can thus be easily adjusted, and it Wil-l be seen that as they carriage i'noves backward and forward, the end plates ot the carriage Will alternately strike the abutments 93, stopping the carriage.

AThe machine has the usual bell arrangement to indicate when the end' of a line is being approached, and as shown the bell 9G has its tongue 97 coiled around a support, While an extended end 97a projects into the path of the end plate of the carriage which therefore strikes the tongue end .and rings the bell.

It will be seen that l have described a. nmchine which is simple for a typewriting niachine, and which has the parte constructed and arranged so that theycan be easily and cheaply built and readily assembled. The machine is not intended toran'- especially swift machine, but is..intended to bem@ cheaply built machine which will serve the purpose of a typewriter in very many places', and which can also be made cheap enough to be sold for a toy machini Qbviouslyvthe particular manner of hanging and `connecting the" operating parte, not material, but it is essential 'to have the parte arranged in the combination expressegand Kiley particular stress on the means for o ting the type block and printing charact and pecially the ineens for bringing the block to its approximate printing position and then centering and holding it while a character is 'being printed.-
