TYPE-WRITING MACHINE.

Toiall whom it may concern:

. Be it 3 known that We, AL XANDER T. BROWN and ARTHUR J; Bruce's, citizens of the United States, and residents of Syracuse.

' in the county of Onondaga and State of New York,-,have invented certain new and useful Improvements in Type-VVriting Machines, of which; the following is-a specification. a Our invention relates to typewriting machines and the main object of said invention ,is' to provide'simple and efiicient means for doing. what ,is known as condensed record work, as willihereinafter more clearly appear.

. To the'above and other specific ends which .will appear in" the following description, our inventionconsists in features of construction,=arrangements of parts. andeombina- .tions of devices to be hereinafter described In the accompanying drawings wherein like -reference:characters indicate corresponding partsin the various views, Figure l is a rear elevation of a platen and platen frame%,

together with thevarious features'of our in vention shown as applied thereto; the'view having certain of the parts broken away.

i Fig. 2 is a'transverse sectional view of a pl-at'e'n,] )laten frame and carriage, the sectionheing taken 1 1 the line a2.m of Fig. 1 and looking in the direction of the arrow at said line. Rig. 3 is alike View of the sametalten on the line y-y of Fig. 1. and looking in the direction'of-the arrow at said line, and with 5-i5, "'the side edge guide'omitted. Fig. l is a transverse sectional view also taken on the line of Fig land looking in the direction of thearrow-at said line and with the paper gnide and feeddevicesomitted and position. Fig. 5 is a view which corresponds to Fig. 3, except that the movable paper feed devices are shown thrown and locked out of action."

'4- '5 hile we have shown our invention ap'plied to a Smith Premier machine, or so much thereof as may be n'ecessaryin order to illustrate our invention. it should be un- -derstood that the invention may be em 5Q ployed in the various styles of typewriting machines. The carriage comprises the carriage frame .1 which has a forward grooved bar or rail 2 that coiiperateswith anti-friction'balls 3-,

56 which are likewise-received. in a grooved rail Specification of Letters Patent. Patented Jan, 1'? 1911 Application filed October 29, 1904. Serial No. 230,581.

with a grooved rail or bar -5 that cooperates with anti-friction balls 6 received in a.

grooved rail 7 supported on the top plate of the machine, so that the carriage is supported on ball bearingsand is adapted to travel from end to end of the machine. A platen 8 is secured to a platen shaft 9, the extending ends of which'are received in bearings 10 in the carriage frame when the platen is in its normal position. The, shaft 9 is journaled in end plates 11 of a platen frame, one of said end plates having a forwardly extending arm 01' finger 12 and longitudinalbars 13 and 14 are connected to the end plates. The shaft 9 is adapted to slide along the guiding bearings 15' when the finger piece 12 is turned back so as to expose the last written line on the sheet. This turning action of the platen-and frame to expose-the writing is facilitated by hook-like links 16 pivoted at 17 to the carriage, the rear ends of the links coiiperating with-studs l8 projectii'ig laterally from the end plates of the platen frame. '1. he construction thus far described constitutes a portion of the wellknown Smith Premier machine.

The rod 14: constitutes a support for bearing-blocks 19 to which a paper tableQO-i secured. The bearing blocks are apertured to provide journal bearings for the reception of a rock shaft 21 which is provided at one end with a crank arm or finger 22 that projects forwardly as indicated in Fig. 2. This rock shaft 21 has depending fingers 23 secured thereto and curved as represented in Figs 2 and 3 in order to pass around the bar 14 and to coiiperate with theforward side of sleeves 24 that are carried by a spind le or shaft 25 of a central paper feed roller 26, the fingers 23 being located near each end of theroller 26 as indicated in Fig. 1. The ends of the shaft 25. are received "in bearing openings in arms '27 that extend downwardly from the bar let on which they are loosely mounted. ,A-spring 28-bears at 7 its 'fIPG end against each of the sleeve S 24 V and each spring is secured at. one end,-'as :j

indicated at 2-9, to one of "the bearing blocks The rear of the carriage. isalso provided 19 and is bent, to form a loop 30'. A screw threadedspindle 31 projects from each blockl9 and extends at its rear end through an opening 'inithe. associated sp1'ing'28; A .headed nut 32 cooperates 'vvitheach screw- .45 -Thus eaeh'of the springs 44: 1s bifurcated spindle and the contractedportion 33 of the chine. The end of the bar opposite the Sllt associated nut likewise extends through the opening in its spring. By these means an adjustment of the tension of each spring 28 may be effected by an adjustment of the associated nut on its threaded spindle 31, so that the spring tension exerted upon the main feed roller 26 may be varied at will and an independent adjustment at each end of the feed roller 26 may be effected,

Each of thearms 2? extends beyond the point where the shaft 25 is journaled therein, so as. to provide a bearingfor a pin 34:

onJwhicli a paper-plate 35 is journaled.

The ends of the arms 27 terniinate in lingers orabutnients 36 which limit the n'iovement of the paper plate in one direction relatively to the arms so that when the feed roller 26 is moved .awaytfroin the platen, as

indicated in Fig. 5, the paper plate 255 will likewise be removed from contact with the platen or the paper thereon. Suitable spring paper guide lingers 37 extend at their rear.

.endsover the vibratory paper plate -35 and are secured at their forward ends, as at 38, to adpistable slides 35). It will be seen that the feed roller 36 is moved away from the platen.

At each endtof the paper feed roller 20 is situated a feed roller 4L0, that is journaled in depending fingers or arms etl loosely' mounted on the bar 14 and are spaced apart thereon by spacing sleeves 4-2 on each side of a securing block or car 43 that is riveted a bearing ltlthcreinfor the reception and longitudinal ad ustment of a bar 50 which-'- or otherwise secured to the paper table and is apertured to constitute a bearing for the rock shaft 21. Each of the terminal feed rollers 4'0 cooperates withthe platen near an end thereofand is at all times pressed against the platen by a spring 44 similar to the springs 28, and which is mounted and has its tension adjusted in a like manner.

feed roller 40, whereas an adjusting nut 46 similar to the nuts 32 previously described,

- cotiperates with each spring to effect an {at justment thereof. The upper endof each spring 44 is secured to an associated block 43 by a pin or other securing means 47.

The rearof the, paper table has abrac'ket 4.8 secured thereto and this bracket is bifur} cated to form two arms, each of which has constitutes a support for the side edge paper guide "51 that extends from one end of the bar and at right angles thereto and projects forwardly over the upper edge of the paper table and at right angles to the'plane of the paper as is introduced into the maedge guide has a ball or finger piece 52 to facilitate a longitudinal adjustment of the bar and guide and to prevent the bar from being slid entirely out of its bearings. One side of the bar is flattened as indicated at 53 and a leaf spring 51 extends into the bifurcated portion ofthe bracket and bears at its free end against the flattened portion of the bar. This leaf spring is secured in place by. screws 55 which likewise secure the bracket to the paper table or to a block 50 on the rear face thereof. The so-called bifurcated portion of the bracket t8 has a forwardly extending central arm or finger that is turned at its upper endto form the hooklikc portion 57 which extends over the top edge of the paper table as represented in Fig. at. This side edge guide is preferably located at: the left-hand end of the platen and constitutes a gage or guide by which the left-hand side edge of the paper or certain sheets introduced into the machine may bear, in order to determine the position of said sheet or sheets in the machine, as will hereinafter more clearly appear.

The arm or linger 22 has a gravity latch pivoted thereto at 59 and the lower end of this latch has an elongated slot (BU-therein and into which projects a pin (31 secured to the platen frame. The slot 60 connects at its upper end with a laterally extending slotted portion 02 in which the pin is likewise adapted to be received as indicated in Fig. 5 in order to lock the arm 2 in the depressed position and thereby maintain the central feed roller 26, and the parts con trolled by the movement thereof, away from the platen. The latch 58 is provided with a tail piece 63 by means of which the locking engagement between the latch and pin may be effected, as indicated in Fig. 5. Thus, for instance, a mere depression on the arm 22will result in moving the feed roller 26, the paper plate 35 and the paper fingers 37 away from the platen and the gravity of the latch 58 will tend to maintain the pin within the elongated slot (10 so that when the arm 22 is released the parts will imme- 'pression of the arm ZZ'the slot 62 nfill be brought opposite the pin 61 and the pin will be seated in. said slot--so as to lock the parts against the tension of the springs 28 which tend torestore the parts to normal position. In this ananucr the feed roller 1 write the date, name and item upon the hill 26 and the paper devices associated therewith will be locked away from the platen,

thus enabling the operator to employ both hands to make such changes in the disposition of the sheets as may be necessary. lYhen the operator desires to release. the feed roller from its locked position, it is merely nece. my to exert a slight downward pressure on the arm 22. Then the latch 58 will drop to its normal position with the pin 61 seated in the slot (i0 and the parts are then tree to be-restorcd to normal position upon the release ot the arm It will be observed that the feed rollers.

26 and T0 are in substantial alinement longitudinally of the platen and are situated at that side ot'"the platen where the paper is introduced into themachine; that the feed roller 26 is intermediate of the terminal feed rollers l0 and cooperates with the middle'portion of the platen; that both the feed rollers 26 and 40 receive the paper directly from the paper table and with the platen form a bight into which "the paper is directed by the paper table; that these feed rollers are situated between the point of introduction of the paper into the machine and the printing line; and that the central feed'roller may he moved toward and away from the platen independently of the feed rollers 40 by an actuation of the arm 22.

In addition to the mechanism thus far described, it should be umlerstood that'the machine is provided with the usual-detent' mechanism (not shown) for the platen, to prevent an overthrow thereof and an accidental displacement of the' platen from the line space position to which it is moved.

in the o 'ier'alion of the instrumentalities heretofore described for condensed record 'w'n'k, and as an example of one form of such work, it may be assumed that it is desired to write the bills on a so-called bill sheet or bill head a; that it is desired at the same time to provide a carbon copy of such hill on a so-called condensed record sheet I; a carbon sheet 0 being interposed he- 'iwirn the order that the items or matter writte 'i'upon the bill head" may be transferred to the re ord sheet In the present instance it will he observed that the bill sheet 0. is narrower than the record sheet 7) and that the position of the comparatively wide record sheet in the machine may be determined by the side edge guide.

The bill sheet and carbon sheet are confined to the action of the central feed roller 26, whereas the termim'il feed rollers 40 do not hear on the hill and carbon sheets but time \vheu'the hill sheet is being removed hear on and cooperate with therecord sheet only. All three sheets being introduced into the machine and placed in the machine in the manner dcscril. ed, the operator may? bill and record sheets in 'may be locked in the released position by applying pressure on the tail piece (53 of the latch. The release of the feed roller 26 in the manner described wholly releases the bill and carbon sheets so that they may be readily removed from the machine, without turning the platen and independently of the record sheet which is still clamped in place in the machine by the terminal feed rollers 40 which cooperate therewith. A second bill sheet and carbon sheet may now be inserted into the machine until the first line to be written on is brought to the printing point. The feed roller 26 may then be released by a slight downward pressure on the arm 22,-

and the second bill may then be written and duplicated and removed from the machine. A number of bill sheets may be written and duplicated on the record sheet. This may continue indefinitely or until the record sheet is filled, when a new record sheet, bill sheet and carbon may be introduced, and the operation continued as heretofore described. It- Will be seen that in this manner a so-called condensed record may be kept of the bills written on the machine by using a single short carbon sheet and that I there is no necessity for making cumbersome records by occupying undue space between the different items on the record sheet corresponding to the printed headings on the different bill sheets, or of keeping a separate duplicate sheet for each hill that is filled in on the machine, and that copies in condensed form may be readily made during the operation of writing bills on themachii'ie.

\Vhile we prefer to employ narrow carbon sheets correspomling substantially to the width of the bill sheets so that the carbon may be removed with each bill sheet as it is written, we may, nevertheless, employ a (iill'l)()l'l-$-Ill(:(.tl corresponding substantially to the width of the record sheet, in which case the carbon sheet would not be removed with each bill sheet as heretofore described, but would be maintained in the machine with the record sheet and l'ed torward with the record sheet as the latter is advanced with each new bill shoot.

it will he undersloml that. during the shown). Any suitable leading edge stops may be employed to arrest and square the sheets as they are introduced into the machine.

While we have shown and described a single central feed roller 26, it should be un derstood nevertheless, that this roller may be divided. so as to provide a plurality of main feed rollers instead of a single feed roller 26 and that various other changes may be made without departing from the spirit of our invention. For example, some other formof pressure device may be used instead of the feed rollers 40.
