SPECIFICATION forming part of Letters Patent No. 784,444, dated March 7', 1905.

Application filed December 28, 1896. Serif@ Nm 6171157' To n// 'uffi/ont it 'ntfty/ concern:

Beit known that I, BURNHAM C. S'rroiinnv, a citizen of the United States, and a resident of Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Type-lVriting' Machines, of which the following is a specification.

My invention relates to the margin-g'ag'e mechanism of type-writing machines; and its object is to improve the construction and simplify the operation thereof.

My invention consists in the provision of a releasing' device for the margin-gage actuable by pressure in the direction in which the gag'e is to be moved; and it further consists in the features of construction and combinations of devices hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure l is a front elevation of the margin-gage mechanism arranged in connection with the papercarriag'e of a type-writing machine. Fig'. 2 is a plan of the margin-gage and paper-carriage, the letter-spacing rack being partly broken away to expose its adjusting-slots and the front bar of the platen-frame being partly broken away to expose the margingage below. Fig. 3 'is an end elevation of the g'age and carriage, partly in section.

Figs. 4 and are perspective views of the re- -hing'ed thereto, the hinge-joint being concentric with the guide-rail 3. The rack-frame comprises a pair of arms 4,. extending rearwardly from the hinge and united at their rear ends by a cross-bar 5, to which 'the rack 6 is secured by screws 8, the holes 7 for the screws being' elongated, so that the rack may be adjusted longitudinally upon the cross-bar.

Any suitable letter-spacing' mechanism 9 is mounted upon the top plate in engagement with the rack 6 to permit the step-by-step movement of the pzwer-carriage under the pull exerted by the usual propelling-spring. (Not shown.)

The cylindrical platen i0 is suitablymounted in a rectangular frame consisting' of end bars 1i, front bar 12,'and rear bar i3, from which project rearwardly ears 14, whereby the platen-frame is supported upon the rail' 3 and also Vhinged to the rack-frame, so that the )laten may be swuno' u to ex )ose the writinO'.

The front bar 12 of the platen-frame is provided with a-roll I5, which runs upon a cylindrical front rail or bar I6, supported upon standards 17, rising from the top plate. A lug or foot may be used in place of a roll.

Upon preferably the rear side of the front rail 16 is cut or formed a series of margingage teeth or stops 18 at intervals that by preference correspond with the teeth of the letter-spacing rack 6.

Arranged to slide upon the rail is a short sleeve 19, open at the top, so as to leave a clear runway for the roll I5 and so as to permit the sleeve to be slid along the rail beneath the roll. rPhe sleeve encircles the rail for a sufficient distance to secure a iirm grasp thereof, but (its the rail loosely, so that it may slide freely thereon. An in wardlyproj ecting pin 20 upon the sleeve engages a groove 2i, cut in the under front portion of the rail for its entire length to keep the sleeve in proper position. The rail thus constitutes a slideway along which the gage may be moved in either direction. .It is not essential that the slideway should be a rail or that it should be a bar, as the margin-gage could be arranged to move along' in a groove without departing' from the spirit of my invention. flt is not essential that the series of stops be cut in or' upon the slideway so long as the margin-gag'e is arranged to move upon the slideway and engage any of the stops. It is not essential so far as a part of my invention is concerned that the margin-gage be arranged upon the vframework of the machine, as the carriage could be provided with a slideway and the gage be arranged thereon. The invention is adapted as well for machines in which the paper remains stationary and the types-are arranged upon a carriage.

Preferably the sleeve is provided with an enlargement 22, which serves as an abutment to limit the return movements of the papercarriage in a manner presently to explained. Arranged upon the sleeve and adapted to engage any of the stops 18 within the limit of its travel is a movable stop-tooth 26, which may be of any suitable construction` but which preferably is formed upon the righthand end of a vibratoryarm 23, the tooth and the arm taken together constituting a pawl whereby the gage is locked against movement to the right at the impact of the paper-carriage. To secure the pawl to the sleeve, a vertical pin is driven through a hole made in the abutment 22 and down through a corresponding hole made in an ear 25, arranged upon the sleeve below the abutment. The pawl is arranged between the ear and the abutment, and the pin passes through a longitudinal slot 24 in the left-hand end of the pawl, whereby when the pawl is in engagement with a stop permits a slight movement of the sleeve to the right at the impact of the paper-carriage until the right-hand rear edge thereof contacts with a shoulder 26, formed upon the stoptoothV 26, whereby the carriage is brought to a stop independently of the pin upon which the pawl is pivoted, so that a small pin may be used without danger of injury thereto. Many other ways may be employed for supporting the stop-tooth upon the slideway.

The stop-tooth 26 is pressed into engagement with the stops 18 by means of a flat spring 27, (shown only at Fig. 2,) one end thereof being fixed to the abutment 22 and the other bearing upon a vertical pin 28 upon the pawl-arm 23. When the margin-gage is pushed toward the left, the stop-tooth 26 will ride over the stops 18, but when pushed in the opposite direction will lock therewith.

To release the tooth from the stops, so that the gage may be slid to the right, I have provided a releasing device which is actuable through pressure applied in the direction in which the gage is to be moved, whereby with a single motion made by the operator the gage may be both released and moved along the slideway. It is not essential that the push be made in a direction precisely parallel with the slideway so long as the gage may be moved along the slideway by the same movement that effects its release from the stops.

I have preferably constructed the releasing device with a handle, which is adapted to carry the gage along the slide in either direction.

I have devised various constructions for carrying out this part of my invention, but prefer that shown in the drawings, in which the` releasing device is made in the form of an elbow-lever provided with a pivot-hole 29 near its bend and confined between the pawl and the abutment 22, a portion of the pawl-arm being cut away at 30 to make room for the arm 31 of the elbow-lever, the other arm 33 whereof extends forwardly, being bent at '34 to pass beneath the rail in position to be reached by the operator. The elbow-lever has a bearing upon the pivot-pin of the pawl above referred to. the pin passing through the hole 29 therein. I/Vhen the finger-piece or handle 33 is pushed toward the left, the arm 31 will bear upon the sleeve at 32, whereupon the handle and sleeve will move as one piece to the left along the slideway. The operating-lever 33 is provided with a short finger 35, which eX- tendsinto a cut-away 36 in the sleeve, whereby the lever 33 is steadied and whereby a bearing is provided for the lever when pushed toward the right.

The right-hand extremity of arm 31 is pointed, and the cut-away 30 in the pawl is beveled to match the point, as shown at Fig. 2, whereby when the handle 33 is pressed to the left the pawl is permitted to vibrate (as it rides over the stops 18) independently of the elbowlever and whereby when the handle 33 is pushed to the right the pawl is swung rearwardly in unison with the arm 31 against pressure of spring 27, so that the stop-tooth 26 is released from the series of stops 18 and the gage moves to the right, as shown by the diagram at the lower right-hand corner of Fig. 2.

From the foregoing explanation it will be understood that the gage will remain steadfast at the impact of the paper-carriage, but that it will slide freely in either direction in response to pressure applied to the handle or finger-piece in the direction in which the gage is to be moved. I believe I am the first to provide a margin-gage with a handle which may be manipulated to move the gage in either direction along the slideway by applying pressure to the handle in the direction in which the stop is to be moved, and I seek to cover this improvement broadly herein and do not desire to be considered as limiting myself to a handle and releasing device having the general construction and operation set forth.

The paper-carriage ispro vided with an abutment adapted to cooperate with the gage both to mechanically determine the operative position of the/gage and also to thereafter limit the return movements of the paper-carriage. 'Ihe abutment is made, preferably, in the form of a gravity-pawl 37, pivoted at 38 to the front bar 12 of the lplaten-frame, which is provided with a stop-pin 39, that enters a slot 40 in the pawl, whereby the pawl is supported in normal position and prevented from excessive vibration when the platen-frame is swiftly swung up.

To set the gage in working position, the paper-carriage is first brought to the position where the first letter of each line is to be IOL) TIO

printed, and the handle is then pushed to the left to carry the g'age along' the slideway as far as it will go-that is, until it is checked by contact of projection 22 with pawl 87. This mechanically determines the position of the gage and renders it unnecessary to provide a scale therefor. turn movement the paper-carriage will be checked at the same place by contact of the pawl-abutment 37 with the projection Q2. 1f the paper-carriage were originally set at the position indicated at Figs. 1 and 2, the margin-gage would pass beneath the roll 15 owing to the openingin the top of sleeve 19, and the roll would thereafter pass freely by the gage. By having the carriage-abutment arranged at the left of the roll l am enabled to secure an ample range of adjustment for the margingage without unduly prolonging the rail beyond the length required for the travel of the paper-carriage.

'l` he jmper-carriage may at any time be passed to the right beyond the margin-gage whenever the platen-frame is swung up to expose the writing, or it need be lifted from the front rail only a distance suflicient to enable the abutment 37 to clear the projection 22, as shown at Fig. 3, and upon the succeeding normal movement of the paper-carriage to the left the abutment-pawl 37 will ride over the projection Q2 and will then drop to working position.

XV hen the margin-gage is no longer needed, the handle is pushed to the right, carrying the margin-gage far as it will go.

By constructing the gage to pass the front roll 15 I am enabled to secure a long range for the gage.

rlhe letter-spacing rack 6 is provided with longitudinal slots 7, so that the position of the paper-carriage, and thereby the position of the abutment thereon, may be adjusted for a slight distance 'with reference to the rack 18, as in practice there should be a slight recoil or backlash of .the paper -carriage after it strikes the margin gage and before it is cheeked by the letter-spacing rack, and by means of the described adjustment the proper amount of recoil may be determined.

Some parts of my invention may be used without others, and I do not, therefore, desire to be limited to a machine embodying all portions of the invention.

It should be understood that various features of'construction are not essential to different portions of the invention in connection with which they are respectively described; but it is obvious that in numerous other instances dejmrtures may be made from the particular features of construction set forth without departing from the spirit of my invention, and l do not, therefore, desire, so far as certain features of my invention are concerned, to be limited to the particulal'construetions and'arrangements herein set forth At each subsequent re- It will be seen that the cooperating marginstops are located at the front of the machine, where they are readily accessible to the operator from the front of the machine, that the adjustment of the adjustable stop may be conveniently effected, and that by an easy manipulation of the stops one may pass the other when the operator desires to write within the margin.
