SPECIFICATION forming part of Letters Patent No. 581,928, dated May 4, 1897;

Application tiled March Sl, 1896.

7' 0 LZZ whom it 71mm concern,.-

Be it known that l, GEORGE B. XVEBB, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Type- Writing Machines, tbc., of which the following is a specification.

My invention has for its main object to provide efficient means for guiding, holding, and feeding cards, envelops, heavy paper, the.; and it consists in the various features of con# struction and combinations of devices hereinafter more fully described, and particular] y pointed out in the appended claims.

In the accompanying drawings, Figure 1 shows a top plan view of the paper-carriage of a type-writing machine with my improvements applied thereto, a portion of the platen being1 broken away. Fig. 2 is a front elevation of the same, but with the improved devices shown in a different position relatively to the carriage and platen. Fig. 3 is a vertical crosssection taken at the line X X of Fig. 1, these two views showing the cardholder in abnormal position or in the position to which it is adjusted when the card, die., is being inserted or applied to the platen. Fig. 4 is a vertical cross-section taken at the line Y Y of Fig. 2, these two views showing the card-holder in its normal position. Fig. 5 is a perspective view of the contrivance detached and in section or part-ly broken away at one end to more fully show the detail construction and arrangement of parts, and Fig. (3 is a detail sectional view of the attachingbracket, dac.

In the various views the same part will be found designated by the same numeral of ret'- erence.

1 designates the paper carriage or frame, which may be of any suitable construction 2, a cylindrical platen adaped to rotate within said carriage or frame; 3, a pressure or feed roller supported at the lower ends of pivoted arms 4, provided with springs 5 for forcing said roller against the platen.

To the pivoted arms at each end of the carriage is attached by a screw an arm 6, which extends downwardly and forwardly, and to Serial No. 585,529. (No model.)

the extremities of these arms is secured a scalebar or paperblade 7 which entends across and beneath the platen and presses against the same for substantially its whole length on a line slightly back of the vertical center of the platen, all in substantially the usual manner.

Attached tothe front T- shaped barS oi' the carriage by a binding-screw 9 and clampingplate 10 is a bracket 1l,which supports the various devices comprising` my improvements. The said bracket is formed with a horizontal member or plate-like portion 12, which bears upon the uppersurface of the front carriagebar, and also with a vertical member 13,which is provided with a slight recess 14 to receive a rib 15 at the upper end of the vertically-arranged clamping-plate 10, the lower edge of which is inclined or bent at 16 to extend under the top of the T-shaped bar 8.

Between the top and bottom edges the clamping-plate 10 is formed with a perforation for the passage of the threaded end of the binding-screw 9, which end takes into a threaded hole in the bracket l1. The binding-screw is provided with a shoulder 17,

which bears against the front side of the clamping-plate when the screw has fully entered into the threaded hole in the bracket, which latter is prevented from moving bodily forward during the tightening or clamping action by reason of a flanged portion 18 at each end which bears against the inner edge ofthe T- shaped bar.

Extending downwardly from each flanged portion 1S is an arm 19, which terminates in i a bifurcated eye or bearing 20, and extend ing upwardly from the vertical member 13 at eachend is an eye or bearing 21.

1n each bifurcated bearing 20 is supported by a pivot-pin 22 Va roll-holder 23, provided at its lower forked end with a small pressureroll 24 and axle therefor. Attached to the said roll-holder at one end by a screw 25 is a curved leaf-spring 26, which at its free end bears against the depending arm 19, and by which construction and arrangement the roll is pressed or forced against the platen.

Supported in the bearings 21 is apivot or hinge pin 27, which by a transverse bar 2S is connected to another pivot or hinge pin 29, arranged parallel to that marked 27 and supported in an elongated eye or bearing 30, attached to or forming part of a curved plate or frame, (designated in its entirety b y the numeral 31.) A wire spring 32 is provided to normally hold the frame 31 up and to cause it to return to its normal position when released of the pressure of the fingers of the operator after the insertion of a card, as will hereinafter more fully appear, This spring at its ends is coiled about the hinge-pin 27, and its extremities bear against the rear side of the vertical member 13. Between the coils the spring is bent into U form, and the bar portion thereof is extended over to bear on the under side of the elongated eye or bearing 30 on the frame 3l. The hinge-

pins

27 and 29 are prevented from casual detachment from their bearings by means of small pins or cotters 33, which pass through transverse holes in the prolonged ends of said hinge-pins.

The curved frame or device 31 is formed or provided with a lower bar portion 34, a top bar portion 35, end bar portions 30, and a central bar portion or strip 37, which latter in the normal position of the frame rests against the inner edge of the' horizontal member 12.

On either side of the central strip 37 is an opening 3S, through which the flanges 18 and the arms 19 protrude slightly;7 and through which the roll-holders 23 and rolls 24 may pass and operate.

On the front side of each arm 3G (viewed from the front of the machine) is formed or attached a projection or finger 39, which is adapted to contact with the upper surface of the T-shaped bar 3 when the frame 31 is depressed, and for the purpose of facilitating lthe depression of said frame it is provided with a forwardly-extending finger-piece 40, arranged about centrallj7 of and formed integral with the top bar 35.

On the inner or face side of the frame 31 at each end is provided an adjustable guide or card-stop, which is made in the form of an arm or strip 41, having at its lower end a lip or hook 42, which is fitted to slide in a slot 43, made longitudinally in the arm 3G, and the said stop 41 is attached by a setscrew 44 to the bar 35, whereby the strip or arm 4l may be adjusted in the direction of its length, so as to bring the lip or hook portion 42 nearer to or farther from the edge of the bar 34, and hence limit or regulate the insertion of the card to the extent desired and as will be hereinafter more fully eX- plained.

In use the contrivance occupies the position shown at Fig. 4, the spring operating to hold the frame 31 up and with the lower edge of the bar 34 pressed against the platen, or the substance to be printed on between it and the platen, and the springs 26 operating to hold the rolls 24 pressed against the platen.

The operation of inserting a card, envelop, or other stiff or thick substance is illustrated at Fig. 3, in which View it will be observed that the frame 31 is depressed. When pressure is applied to the finger-piece 40, the frame descends and at the same time swings about the pivot or hinge pin 27 until the stops 30 strike against the upper side of the front bar 3. During this action the frame is free to independently oscillate or pivot slightly about the hinge-pin 29, and when the stops 39 have come to a bearing the frame 31 will occupy the posit-ion shown at Fig. 3, at which it will be seen that the lower edge of the bar 34 has been projected rearwardly to the vertical plane of the scale or paper-blade and also that the lips or stops 42 have been carried down and back against or in close proximity to the surface of the platen in the vicinity of the impression-point. It will also be observed from this figure that between the edge of the bar 34 and the lips or stops 42 and the surface of the platen a space or pocket 46 is formed which has a comparatively wide mouth and which tapers or converges to the points where the lips touch O1 nearly touch the surface of the platen, whereby the card 47 is easily guided and caused to conform gradually to the surface of the platen.

After the card has been inserted or passed down and forward until its leading edge strikes or abuts against the stops 42 the pres sure upon the finger-piece 40 is released, and the spring 32 causes the frame 31 to rise and to resume its normal position, (illustrated at Fig. 4,) and with the edge of the bar 34 overlapping and pressing upon the leading edge of the card 47. From this view it will be 0bserved that before the writing commences the card is firmly pressed against the surface of the platen along three distinct lines near one another,and hence is forced to conform closely to or bear properly against the surface of the platen for a considerable are thereof, and particularly at the impression-point, so that it is firmly supported or backed and will permit the types to strike squarely against its surface, and thus yield as good impressions as may be obtained with ordinary thin paper. These three lines of contact or pressure will of course be understood to be those afforded by the pressure-roller 3, the pressure-blade 7, and the pressure-bar 34. As the printingprogresses and the platen is rotated for line-spacing the leading edge of the card soon passes up between the small pressure-rollers 24 and the platen. Itis thus maintained in its curved or arc-shaped condition for a longer time and over a larger extent of its body. rl`he presence of these small pressure-rolls 24 obviates the natural tendency of the card to project tangentially of the platen and prevents the inherent spring of the card from neutralizing or overcomin g the spring-pressure ot' the bar 34.

The stops 42, it will be understood, are arrested always at the same locality relatively ICO lIO

to the i-mpression-point when the frame or plate 3l is bodily depressed, and for this reason it will be seen that the introductionof each card is thus limited, gaged, or predetermined, so that the printing may be begun at -eXactly the same distance from the upper edge of the card for a given series or set of cards, which is a matter of considerable importance, especially to librarians or others who desire uniform catalogue or index cards. By making the stops adjustable the cards may be arrested at earlier or later periods of introduction, so that the writing may be commenced at any desired distancefrom the tops of the cards. The card-stops are so related to the edge of the pressure-bar Se as that the said bar will always overlap the leading or upper edge of the card when the swinging frame or plate has returned to its normal position of rest.

It will be observed that the frame or plate 3l acts as a guide or deflectorbothforthein` sertion and for the subsequent feeding of the card during line-spacing, also that its bar portion 34 acts as a pressure device to hold the card against the surface of the platen during the printing operation, and also that its stop portions 42 act to determine or gage mechanically the extent of introduction of the cards, thus relieving the operator of all care, adjustments, and visual examinations, and at the same time insuring uniformity in the introduction and in the printing, as before explained.

The bodily-movable or swinging frame or plate maybe employed to direct the cards and to limit or determine the extent of their insertion without the employment in connection therewith ot' t-he rolls 2a and their su pports, in which event of course the openings in the frame or plate may loe omitted; but even in such case the openings would be preferred, inasmuch as they reduce the weight of the contrivance, which is a desideratum. It will be further understood that while I have shown adj ustable stops for the leading edges of the cards non-adjustable or relatively-fixed stops may be employed without departing from the gist of this part of my invention, and various changes in details of construction and arrangement may be made within the scope of my improvements as defined by the appended claims.

The contrivance is preferably made in the form of an attachment readily applied and removed when desired; but it will be understood it may be constructed and applied so as to form a permanent part of the machine, and may be so modified or changed in strue-` ture as to perform less than all of the functions which it has been designed to serve.
