THOMAS D. XVORRALL, OF WASHINGTON, DISTRICT OF COLUMBIA.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 366,750, dated July 19, 1887.

Application filed November 5, 1885. Serial No. 181,915. (No model.)

To all whom, it may concern:

Be it known that I, THOMAS D. \VORRALL, a citizen ofthe United States, residing at \Vashington, in the District of Columbia, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to improvements in type-writing machines, and especially to that class of machines in which fonts or batteries of type are arranged in a moving frame, as described and claimed in my Patent No. $3 1,503, of January 19, 1886.

Figure 1 is a top or plan View of my ma chine. Fig. 2 is a side view of the same, partly in section, taken on the line :0 a: of Fig 1. Fig. 8 is an end view of the type-carrying frame. Fig. tis a detached view of the centering-bar and a portion of the type-carrying frame. Fig. 5 is a side view of one of the adjustable arms for regulating the spacing of the letters. Fig. 6 is a side view of a portion of the bottom of the main frame, showing the lower rod of the transverse frame passing therethrough.

Referring to the drawings, A is a rectangular frame, on the corners of which are secured the posts or brackets B, in which the rods or bars 0 and D are secured.

E is the type-carrying frame, the rear end of which is adapted to slide back and forthon the rod D to bring the proper letter to the printing point or center.

F is the type-carrying drum or cylinder, 111 which the type are arranged in rows in the periphery thereof. The type drum or cyl1nder is mounted in suitable hearings in the frame E, so that it can be readily turned to bring the proper row of type in posltion to opcrate on the paper, said type-drum being provided with notches or recesses a at one end to receive the sliding bolt G, which is secured to the frame E, so that when the type cylinder is turned to bring the desired row of typeinto printing position it can be locked and securely held in such position. The front end of the type-carrying frame is provided withknobs or handles H, by means of which the frame can be readily moved back and forth on the rod 1). I

I inder, which lies directly behind it.

form the letter or character, it being under- 'stood that the notches in the bar I are marked with the same letters or characters as 0011- tained in the printing line of type in the cyl- The setscrews care for the purpose of holding the sleeve 1) on the bar 0, so that said sleeve can be accurately adjusted to bring the printingcenter directly on the top and center of the paper-drum.

L are bars or brackets adjustably secured to the rear end of the type-frame by means of thumb-screws, said brackets being connected together by a bar, M, which impinges on the pawl-operating mechanism to operate the same, as will more fully hereinafter appear.

N is a frame mounted transversely to the frame A, and connected thereto by means of the rod a, which passes through the sides of the frame. The frame Nconsists of the end pieces, O and I, and the connecting-rods (Z.

R is a rod mounted in bearings d, and ren dered adjustable by means of screws 0 in the ends 0 P, and on which is mounted the paperholding cylinder S, the heads of said cylinder being provided with apertures through which the rod R is passed. The rod It is provided with a left-hand screw-thread, 0, into which a bolt, f, secured on the end of the cylinder, is forced by the spring f, which causes the cylinder S to move rearward as it is turned by the pawl-plate, and when it is desired to move the paper-cylinder forward for the purpose of putting on a new sheet of paper the springbolt is raised and the paper-cylinder drawn forward. The paper cylinder is provided with a slot, T, in which the ends of the paper are secured by means of a beveled strip fitting in said slot over the paper in the usual man ner.

U is a ratchet-disk secured to the rear end of the paper-cylinder S, which is engaged by the pawl plate V to turn the paper-cylinder the proper distance to space between the letters; The teeth of a portion of the ratchetdisk U opposite the end of the slot T are cut away, as shown atg,Fig. 2, so that when the paper-cylinder has reached that point in its revolution and the end of the line of printing has been reached the pawl-plate will drop into the recess causing the pawl-plat'c to strike the hammer i and ring the bell k to warn the operator that the end of the line of printing has been reached. WVhen the pawl-plate drops into the recess 9, it ceases to act on the papercylinder until said cylinder is moved over the slot to commence a new line of printing,which is done by turning the cylinder so as to bring the pawl-plate into cont-act with the ratchet teeth of the disk again,

The pawl-plate V is made of the same length as the paper-cylinder, so that it will operate at all times on the ratchet-teeth of the disk U, no matter in what position the papencylinder is on the rod R. v

The pawl-plateVis pivoted upon arodflV, connecting the two side arms of the pivoted frame XV, said frame being pivoted upon one of the rods cl and held in normal position by the spring 7:, attached at one end to the bed-frame, and at the other to a stay-rod,W of the frame XV. At is shown an aperture for another stay-rod, and the upper ends of the side pieces of the frame WV are connected by still another rod, Z, which lies immediately beneath the bar M of the type-carrying frame, so that when the front of said frame is lifted the bar I is pressed down, rockingthe frameW against the stress of spring 71 and causing the pawlplate to positively turn the paper-cylinder. \Vhen the bar M rises, frame \rVis rocked up ward by its spring h and the pawl-plate drops back one or more teeth of the ratchet-wheel.

As before stated, the bars L, which support the crossbar M, are made adjustable on the type-carrying frame, so that said bar M can be moved toward or from the typecarrying frame, and in this manner adjust the throw of the swinging frame carrying the pawl-plate to regulate or determine the spacing. It will be seen that if the bar M be moved farther from the pivotal point of the type-carrying frame the swinging frame \V will be forced down farther by the upward movement of the front end of the type-carrying frame than if the bar M were nearer to the pivotal point of the type-frame, and thus move the paper-cylinder around to space the distance between the large letters. Vhen spacing for small letters, the bar M is moved forward toward the bar D, or pivotal point of the type-carrying frame.

As a further means of limiting the movement of the swinging frame WV, and the consequent movement of the pawl-plate over the ratchet teeth of the disk U, I pivot one end of the bar A to the top of the end I of the transverse frame N, the other end of said bar being provided with a slot, m, through which the barl of the swinging frame W passes. The

- sesfiso bar A is provided with a series of holes, a,

1 which pass through the slot n, said holes bethrow of the type-carrying frame "to space the distance between the letters, I join the front end of the type-carrying frameto the sliding standard B by means of a sliding connection, which consists of a T-headed projection or hook, r, passing through a slot in said standard, which will allow the front end of, the typecarryin g frame to be raised and lowered,

the throw of said frame being limited by the i The lower end of the standadjustable pin ard B is provided with a hole, which adapts it to slide back and forth wit-h the type-frame on the rod 0.

D. are troughs or strips, of wood or suitable material, secured at one end to suitable supports on each side of the paper drum, while the outer ends of said troughs are secured to the ends of the rectangular frame A.

The bars D are designed to support the inking ribbons or pad E, so that when the type-drumismoved back and forth in the processes of writing the type will be supplied at all times with a suitable amount of ink, and when fresh surfaces of the inking-ribbon are required it may be moved forward by winding or unwinding from the drums or spools F. i.

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

1. In combination with the traveling paper cylinder and its ratchet-wheel, the elongated pawl-plate V, constructed and arranged, as described, to operate on the paper cylinder throughout its travel.

2. In a type-writing machine, the pawlplate V, constructed as described, mounted in the swinging and spring-held frame W, in combination with the type-carrying frame E, provided with the adjustable bar M, and the paper-cylinder having the ratchetdisk U, as set forth.

3. In a type-writing machine, the pawl-carrying frame W, in combination with the slotted bar A, having the holes a and set-screw v, as and for the purpose set forth.

4. In a type-writing machine, the paper drum or cylinder S, having the ratchet-disk ICC U, provided with the recess 9, in combination and recesses corresponding to the rows, and the sliding bolt mounted on the frame as set forth.

6. The combination, with the type-cylinder and its pivoted frame, having the notched bar K, of the adjustable guide-bloek Z), as set forth.

7. The combination, with the pivoted typeearrier having adjustable arms L and bar M, of the paper-roller, its ratchet-Wheel, and the elongated pawl-plate, as set forth.

8. The combination of the sliding frame, the type-cylinder journaled in said frame and having longitudinal rows or alphabets of type and recesses corresponding to the rows, and 15 the sliding bolt mounted on one of the side bars of the frame, as set forth.

9. The eombinati0n,with the paper-roller and its ratchet-wheel, of the elongated pawlplate, the pivoted type-carrier, and the bar M, 20 mounted on adjustable arms L, as set forth.

In testimony whereof-I affix my signature in presence of two witnesses.

THUS. D. \VORRALL.
