TYPE-WRITING -MACHINE.

SPECIFICATION forming part of Letters Patent No. 703,866, dated July 1, 1902.

Original application filed March 2 1897, $erial No- 626,'724. Divided and this application filed February 21, 1898. Serial No. 671,036. (No model.)

' 625,724, patented February 22, 1898, No.

599,429, and relates more particularly to the construction and mode of mounting of the paper-carriage.

My main objects are to provide alight and true running carriage and one in which'the weight of the carriage is supported upon roller-bearings; and my improvements consist in the various features of construction and combination of devices hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanyingdrawings, Figure 1 is a plan view of enough of a type-writing machine to exhibit my invention. Fig. 2 is a vertical cross-section thereof, taken at the line as x of Fig. -1, but showing the top plate of the machine added; and Fig. Sis a detailed cross-section showing a modification of my invention, in which antifriction-balls are substituted for the antifriction-rolls shown in the main views.

In the several views the same parts willbe found designated by the same numerals of 3 5 reference.

Referring to Figs. 1 and 2, 1 is the top plate of the machine, 2 the roller-carriage, and 3 the platen-carrier, pivotally connected thereto in a manner common to the well-known Remington No. 6 type-writing machine. The roller-carriage at near each end is provided with a forwardly-projecting vertical plate 4, to which is pivotally attached the lower end of a link or arm 5, whose upper end is pivotally attached to the rear of the platen carrier or frame 3 by suitable pins 6, also adapted to contact with either of two screw- stops 7 and 8, supported in ears at the upper end of the plate 4. The front side of the platen-carrier frame is provided with a supporting-roller 9, which travels upon a vibratory rail 10, at-

tached to arms 1O and adapted to be actuated by a shift-key (not shown) in the usual manner, whereby the platen-frame and its platen or roller 11 may be shifted for upper-case Work. Normally the pins 6 rest against the screw-stops 8, at which time the platen is in position for printing lower-case characters; but when the shift-rail 10 is vibrated rearwardly the platen-carrier and platen are moved in the same direction, and the pins are caused to strike against the stops 7, and at this time the platen is in position for printing upper-case characters, the type-bars having, as usual, each an upper and lower case type. When the shift-key is released, spring mechanism returns the platen-carrier to its normal position, with the pins 6 against the front stops 8. The platencarriermay be turned up about the hinge or pivotal points 12 of. its attachment to the links or arms 5 for inspection and correction of the work..

The roller-carriage comprises a horizontal top portion 13 and two vertically-depending portions or members 14 and 15, the former being the longer of the two. 16 is a fixed rail for said carriage, secured to bracket 16, mounted on the top plate, and said rail has a horizontal bearing portion 17 and a vertical bearing portion 18. The under surface of the top member 13 of the carriage forms or is provided with a bearing 19, which is opposite to and parallel with the bearing 17 on the rail, and the inner side of the depending member 15 of the carriage forms or is providedwith a bearing 20, which is opposite to and parallel with the bearing 18 on said rail. A vertically-disposed roll or diskv 21 travels on the bearings 17 and 19, and a horizontallydisposed roll or disk 22 travels on-the bearings 18 and 20.

other, and there may be as many pairs as may be desired, two pairs being shown. Each pair of rolls, as shown, is mounted in a holder The rolls or disks "21 and 22 are arranged in pairs crosswise of each 23, with the pivots of the rolls arranged at right angles to each other, and these rollstantially the position illustrated. At the ends of the rollway formed by the fixed rail and the carriage may be located stop-pins 24 to prevent the escape of the rolls. The rolls 21 sustain the vertical component of the weight of the carriage, and the rolls 22 and 28 support the turning moment. In other words, the carriage is hooked or hung upon the rolls 21, while the rolls 22 and 28 oppose its tendency to swing upon said rollers 21, and hence the forwardly-overhanging portion of said carriage is prevented from sagging or tipping.

To prevent the carriage from rising and from tilting or rocking, it is provided with a flanged plate or finger 25, which may be secured to the member 14 by a screw 26, which finger or plate enters a slot or groove 27 in the other side of the fixed rail and travels therein during the movements of the carriage, but without contacting with the surfaces thereof. The said plate or finger is, however, arranged very close to the sides of the slot or groove, so that it may immediately come in carriage 2 and also the weight of the platencarrier 3 when turned up are wholly sustained by the rolls 21; also, that the crosswise rolls 22, together with the roll or wheel 28, which may be mounted on a stud 30 on the carriage 2, guide the carriage laterally-- that is, prevent vibrations of the carriage in a horizontal plane; also, that the wheel 28 and its track cooperate with the rolls 22 and the bearing- surfaces 18 and 20 to steady the carriage in a third directionthat is, to prevent the carriage from rocking or tipping forwardly; also, that the plate or finger and the right-hand wall of the groove prevent the carriage from tilting rearwardly, and also that the said plate or finger and the base of the said groove prevent the carriage from ris ing or from being lifted from the bearing-rail. When it may become necessary to detach the said carriage, the flange plate or finger is of course unscrewed and removed. The weight of the rear portion of the hinged platen-carrier when down in Working position, as shown at Fig. 2, is also borne by the rolls 21, and the tendency of this weight to turn the upper portion of the roller-carriage forward is met and resisted by the crosswise wheel 28 bearing against its track 29. When the platencarrier is shifted rearwardly violently against the stops 7, the tendency to turn or displace the roller-carriage is met and resisted by the plate or finger 25, and for the purpose of further obviating this tendency there may be arranged between the depending member 14 and the fixed rail a stop screw or device 31,

(one or more,) which may be secured either to the fixed rail or to the carriage member 14.

Any violent forward shifting of the platencarriage against the stop-screws 8, which would tend to tilt or displace the roller-carriage, is resisted by the horizontal rolls 22 and 28.

In the modification illustrated at Fig. 3 I have shown antifriction-balls 21" and 28 instead of rolls or disks, the lower ball or balls 28 being arranged to travel in a V-shaped track 32 on the fixed rail and also on a beveled track or way33 on the carriage member 14, whereby the ball is properly supported and prevented from dropping out. The balls 21 preferably travel on plane bearings. The balls 21 sustain the Weight of the carriage, as do the vertically-arranged rolls 21 in the other views, and the said balls 21 also support or steady the carriage horizontally or laterally, as do the rolls 22 in the other views, while the ball or balls 28 perform the function of the horizontal wheel 28 in Figs. 1 and 2. In other respects the construction exhib-. ited in Fig. 3 is similar to that shown in the remaining views.

In the use of the term roller-bearings herein I wish to include both the roll or disk form of Figs. 1 and 2 and the ball or spherical form of Fig. 3, althoughI prefer the former in practice.
