SPECIFICATION forming part of Letters .Patent No. 700,973, dated May 27, 1902.

Application filed April 231 1901. Serial No. 57,052- (No model.)

To all whom it Hwy concern.-

Be it known that I, JACOB E. NEAHR, a citi- Zen of the United States, residing at Buffalo, county of Erie, State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to type-writing machines, and more particularly to mechanism which may be employed in the natureof an attachment for carrying rolls of paper which may be written on by the machine and in which a copy of the written matter may be produced.

To these and other ends, which will hereinafter appear, my invention consists in the novel arrangement and combination of parts to be hereinafter described and claimed.

In the accompanying drawings, wherein like reference characters designate corresponding parts in the various views, Figure I is a side view of sufficient number of parts of a type-writing machine to illustrate my invention. Fig. II is a top view of the same. Fig. III is a rear view of the same. Fig. IV is an enlarged sectional detail view of the connection between the carriage and the rollsupport on the line IV IV of Fig. I. Fig. V is an enlarged sectional detail view of one of the guides, the section being taken on the line V V of Fig. VI. Fig. VI is a sectional view of the same, taken on the line VI VI of Fig. V. Fig. VIIis a detail longitudinal sectional View of one of the supporting-spindles and the bearings therefor, the section being taken on the line VII VII of Fig. VIII. Fig. VIII is a sectional view of the same on the line VIII VIII of Fig. VII.

Referring to the drawings, A indicates the framing of a type-writing machine, to which is secured a traverserod a, which passes through the perforated studs 1), that constitute the connection between the traverse-rod and the carriage B. The forward or front end of the carriage B is provided with a traverse-roll c, that is adapted to bear upon the rod 0, fixed to the framing of the machine, and which constitutes a support for the front of the carriage. This carriage Bis provided with a platen D, that moves with the carriage in the usual manner. The type-bars d are pivoted at e and contact with the platen at the front thereof, so that What is known as a front-strike machine is provided. Motion is transmitted from the key-levers to the typebars in any suitable manner.

Operatively connected to the carriage B is a frame 1. This frame 1 is adapted to carry all of the parts which constitute the attachment forming in part the subject-matter of my invention. In the present instance I pivot the frame to the carriage by passing a screw 2 through each of the side bars 3 of. the frame 1, so that each end of the frame 1 is connected to an end of the carriage.

Upon reference to Fig. IV it will be ob served that each of the screws 2 is provided with a cylindrical portion 4, which extends through a corresponding opening in the side bar 3, and that the inner screw-threaded end of the screw takes in a screw-threaded opening in the rod 5, which constitutes a part of the carriage B. By these means the entire paper-rollframe is caused to move with the carriage in the direction of its feed, but may be turned on the screws 2 as a pivotal center, as will hereinafter more clearly appear.

Adj ustably secured to each of the side bars 3 is an upright bar 6, the two uprights being united by a cross-bar 7, (see Fig. 111,) so as to form a U-shaped frame. The cross-bar 7 of this frame supports a pivoted roller 8, that is adapted to bear upon a rail 9, secured to the framing of the machine, as indicated at 10. The upper ends of the uprights 6 are seated in openings in a cross-bar 11, which constitutes a support for the flanged guides 12. The cross-bar 11 may be maintained in place by set-screws 11*. Each of the guides 12 is provided with a split sleeve 13, which surrounds and bears upon the bar 11 and maintains the guide friction-tight in the adjusted position. In addition to the cross-bars 7 and direction thereon.

be maintained in the adjusted position by a set-screw 20. The bearings 14, 15, 17, and 18 are somewhat similar in construction, though they are intended for different purposes. Thus the bearings 14 are perforated to receive a spindle 21., which may be projected endwise through the bearings, and is secured against longitudinal movement by the sleeves 22, which may he slipped off the bars 6 after removing the cross-bar 11. The spindle 21 is provided with adjustable guides 23, similar in construction to the guides 12, hereinbefore described. This spindle 21 is provided with a pulley 24 at one end thereof for purposes which will hereinafter appear. The bearin gs 15 are connected to the side bars 3 and form the union between said side bars and the uprights 6. The bearings 17 are united to the ends of a U -shaped yoke 25, that carries adjustable guides 26, that are constructed like the guides 12 and 23. The bearings 18 are connected to a yoke 27, which is similar to the yoke 25, except that it extends in an opposite direction. The yoke 27 like- Wise carries adjustable guides 28, which are similar to the guides 12, 23, and 26.

The bearings 16 and 1%) are differently constructed from the others and so arranged that the spindles carried therein are free to rotate and may be readily withdrawn from the bearings. Thus from an inspection of Figs. VII and VIII of the drawings it will be seen that the bearing 16 at one side of the frame has an annular recess 29, which is adapted to receive the end of a tubular sleeve 30, that loosely surrounds the spindle 31. One end of the spindle 31 abuts against the abutment 32, contained within the annular recess 29, whereas the opposite end of the spindle is seated in a recess 33 in the opposite bearing, which recess conforms to contour of its spindle. This spindle 31 is likewise provided with so-called adjustable guides 34, which are constructed like the guides 12 and 23. In order to remove the spindle, it is merely necessary to slide the sleeve along the spindle until said sleeve is withdrawn from its recess 29, when the end of the spindle next to this bearing maybe moved laterally, when the spindle can be moved longitudinally and its opposite end withdrawn from the recess 33. One of the guides 34 may then be slipped off the spindle and the roll withdrawn or a new roll of paper he slipped on the spindle.

The bearings 19 are constructed in the same manner as the bearings 16. The numeral 35 indicates its spindle, which is provided with adjustable guides 36, and the locking-sleeve is indicated at 37.

Mounted, preferably, on one of the bearings 17 is a pulley 38, which is double-grooved and has aband 39, (preferablya rubber band,) that passes around the same in one groove and cooperates with a pulley 40, carried by the shaft or hand-wheel of the platen D. The l other groove. of the pulley 38 cooperates with a band 41, similar to the band 39, and said band 41 extends around the pulley 24 to rotate the spindle 21, that constitute a take-up.

The spindle 31 and the cooperating guides are adapted to support a roll of paper of any desired width in place, and the band of paper 42 extends from this roll around the platen D up to the spindle 21, where the free end of the strip is secured in any suitable manner. It will therefore be observed that the spindles 21 and 31 and their guides constitute reels. One of the spindles, 31, and its guides may be termed a record-supply reel, and the other, the spindle 21, and its guides may be termed the record take-up reel. A second roll of paper is adapted to be supported by the spindle 35, and said spindle and its guides 36 constitute what may be termed a second supply-reel. The band of paper 43, which extends from this reel, passes over the cross-bar of the U-shaped frame 27 and between the guides 28 thereof. The band 43 passes thence over the edge of the papertable 44, around the platen, and over the cross-bar 11 and between the guides 12 thereon. The band 43 may be gummed upon its rear side and provided with serrations at given intervals, as indicated at 45 in Fig. II, thus providing separable labels.

Between the paper strips 42 and 43 is an endless inking-band 46, which has one inkingface that is next to the record strip or band 42. This inking-band may be made of any suitable material, such as carbon-paper 0r textile fabric. The endless inking band passes around the cross-bar of the yoke 27, over the edge of the paper-table 44, around the platen D, over the cross-bar 11, and over the cross-bar of the yoke 25.

From the foregoing description it will be understood that the ordinary paper-feed rolls in their cooperation with the platen effect a feed of all three fabrics in the direction of the length of the bands when the platen is rotated for line-spacing. This same intermittent rotation of the platen transmits a corresponding movement to the pulley 40 and from the latter to the pulley 38 through the band 39. The motion thus given to the pulley 38 is imparted to the pulley 24 through the band 41. This movement of the pulley 24 causes the spindle 21 to be rotated intermittently to the same extent that the paper is fed forward by platen, thereby providing a simple and efficient take-up for the recordstrip.

It will be observed that the entire weight of what may be termed the attachment is supported by the rail 9, upon which the roller 8 bears, the pivotal connection with the carriage being one which merely causes the attachment to move with the carriage.

An important feature of my invention c011- sists of the means which permit the entire attachment to be swung up off the rail 9 in the are indicated in dotted lines in Fig. I, so that access can be had to the feed-dogs andjother parts at the rear of the machine. In other words, when the attachment is swung up access is given to the entire rear portion of the machine.

In the movement of the paper-strip 43 in the direction of the arrow, Fig. I, the written matter is constantly before the operator and an unobstructed View thereof is presented. As the writing progresses the line-spacing or intermittent rotation of the platen causes the three fabrics 42, 43, and 46 to be moved together, and the matter which is written upon the face of the strip 43 is reproduced as a folio copy upon the strip 42, it being underderstood that an inking-surface is provided upon only one side of the inking-band 46. As the matter is reproduced upon the strip 42 it is reeled upon the take-up reel, whereas the written matter contained upon the strip 43 may, if desired, be separated as the writing proceeds.

It will be understood that the usual or any preferred paper-feed mechanism which cooperates with the platen D enters into cooperation with the platen to feed the various fabrics 42, 43, and 46 forward as the platen is rotated, whereas the take-off roller or reel is operated by the pulley-and-band connection heretofore described.

It will be observed that the bearings of the various reels and guides are adjustable, so that the positions of the various reels may be varied to suit the different circumstances. It will also be seen that the provision of the adjustable guides 12, 23, 26, 28, 34, and 36 will permit the employment of various widths of paper.

My invention will be found of greater practical advantage as a label-addressing machine. Thus, for instance, the strip 43 may be gummed upon one side and may be perforated at intervals throughout its length- The paper contained between each two lines of perforations will constitute a detachable label. The operator may place the address or other suitable inscription upon each of these labels, and as it is' being produced a copy thereof is being produced upon the strip 42. This strip 42 may constitute a record and copy which will show the names and addresses indicated upon the labels and may be retained as a reference-list. After the labels have been written on in the manner indicated they may be separated and attached as desired.

It will be seen that no change in the construction of the type-writing machine itself is necessary in order to connect the attachment thereto and that the attachment can be readily removed by unscrewing the screws 2 and 10, when the type-writing machine proper is left at its original form.

From the foregoing description it is thought that a clear understanding of the construction and operation of the mechanism constituting the subject-matter of my invention can be arrived at.

In illustrating my invention I have shown it in its application to the well-known Underwood type-writing machine, though obviously it might be applied to any type-writing machine wherein the invention may be found available.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a type-writing machine, the combination, with the carriage having a platen and a guide in the rear of the platen and at a higher level than the same, a copying-ribbon and a duplicate paper strip passing from said guide to the platen, additional guiding means for the paper and ribbon located in the rear of said guide and at a lower level than the same, whereby the paper and ribbon will be kept in close contact with each other from the guide to the platen, and means for feeding the paper and the copying-ribbon.

2. In a front-strike type-writing machine the combination of a platen, a platen-carriage, an adjustable paper-supply reel operatively connected to travel with said carriage, an adjustable take-up reel operatively connected to travel with the carriage and situated on a higher horizontal plane than the supply-reel, whereby the operator will have an unobstructed View of the written matter as the paper passes from one reel to another, laterally-adjustable guides to said reels to accommodate different widths of paper, means for automatically turning the take-up reel as the paper is fed forward and means for supporting said reels independently of the carriage.
