HORACE S. TAYLOR, OF SPRINGFIELD, MASSAGHUSETTSH IMPROVED MACHINE FOR PAGING BOOKS.

Specification forming part of Letters Patent N o. 10,933, dated May 1G, 1854. i

To a/ZZ whom it may concern:

Be it known that I, HORACE S. TAYLOR, of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Machines Y forlPaging Account-Books; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specication.

The machines which have been contrived for this purpose are costly and not within the reach of any but the largest manufacturers.

The object of my invention is to produce a paging-machine of small cost that shall be simple in its construction and easily repaired in case of the breakage or derangement of its parts; and my invention consists in the employment of a revolving disk or cylinder, in the periphery of which are secured common printing-types which may be taken out and replaced by others when desired, whereby I am enabled to make use of figures of various sizes and descriptions, to suit the various sizes and characters of the books to be paged.

To enable others skilled in the art to make use of my invention, I will proceed to describe the method which I have adopted of carrying` it out.

Figure l is an isometric view of my inachine; Figs. 2, 3, 4, and 5, detached views of diiferent parts, which will be referred to here inafter.

I will iirst explain the construction of the cylinder or type-carrier which constitutes the l basis and main feature of my invention, and

then pass to the parts of the machine which are merely subsidiary thereto, giving finally the operation of the complete machine.

A are the standards which carry the operating parts of the machine, and which are connected together by crossbars B, and secured to a suitable foundation C in any appropriate mannen D is a shaft which runs in bearings E upon the tops of the standards A. The shaft D carries the typeholder, which is constructed of two parts, as follows:

F (seen in section in Fig.v 5) is the outer ring of the holder which contains the cavities which carry the types a.

G is the back or confining plate of this holder, also represented in section in Fig. 5, which is brought up against the plat-e F, the two ,being secured together by turning the buttons b, as seen in Fig. l.

The shaft D, and with it the type-holder, is rotated in the following manner: H is a ratchet-wheel upon the shaft D, having peculiarlyformed square-shouldered teeth, the number of these teeth being equal to that of the numbers in the type-cylinder.

c is an arm attached to a ring e, which revolves freely upon the shaft D, and which also carries an arm f, which is hinged to the upright lever I. This lever is connected with the treadle K at the point g, which is retained in the elevated position shown in Fig. l by the spring L.

d is a pawl pivoted to the arm c, which bears upon the teeth of the ratchet-wheel H, and by the motion of which this ratchet-wheel is rotated.

t is a retaining dog or pawl, with a square tooth calculated to lit between the teeth of the ratchet-Wheel, and `thus retain it from turning in either direction. This pawl is pivoted at the point 7c and 'is pressed up to the ratchet-wheel by the spring Z. One end of this dog passes through a slot in the upright plate m, where it is operated in the following manner: n is a spring attached to the rod I, having a catch o at its lower extremity. As the rod I descends, the catch o slips over the inclined end of the dog i, and as the rod Iasscends the catch o raises this end of the dog, the tooth of which is thus disengaged from the ratchet-wheel II the instant before the latter is revolved by the pawl d. The typeholder being revolved into proper position, the impression is made upon the sheet in the following manner: p is a table or platen upon which the leaf to be printed is laid, it being held between the fingers r, and the platen p is forced down into the position shown in Figs. l, 3, and 4 by the spring q. s is a lever pivoted at t, and connected with the shank of the platen p at u. The other end of the lever s is connected with the rod M, which has a slot w at its lower extremity. The treadle K has a pin ac, (seen in dotted lines in Fig. V1,) which enters the slot in the rod IWI, by which means the latter is depressed at the last nstant of the descent of the treadle K, and

thus the platen is raised and the impression is made upon the sheet.

N is an endlessband of blotting-paper (represented in the various figures in blue lines,) which is Wound upon a roller a, and passes up and over the platen through the guide b and onto the roller c. This band of paper has a slight forward motion as themachine is operated, which is communicated in the following manner: d is a pulley upon the shaft D, from which the band f passes around the pulley c upon the roller c. As the shaft D revolves the vband N is slowly fed forward over the upper surface of the platen.

In lieu of arranging the types upon the periphery of a cylinder, as above described, I have in some ot' the machines which I have built'secnred them in lon g clam ps, which were fed through as required, by means of. a pinion and rackbar, the objectin each'case being to use removable types in place of the expensive chain-types heretofore employed.

Operation: The types being arranged in the proper order consecutively Within the recesses of the plate F, the plate G isclamped to it' by means of the buttonsb, as described. The leaf'. of thebook to be printed is then inserted between the ingers r, so asl to lie immediately over the platen p. The treadle K is depressed, and the pin Working. in the slotw of the rod M, raises the platen p, and the impression is made,the cylinder remaininglclamped in position, the tooth of the dogV t' preventing the ratchet-wheel I'I from. turning in either direction. By the descent of the treadle K the catch o is slippedover the end of the dog t', and thevpaWl-CZ is retracted to engage another tooth of the ratchet-Wheel.

\Vhen the treadle is released, it is again raised by the spring L, the platen is caused to descend by the spring q, the catch o disengages the dog 'L' from the ratchet-wheel H, and the paWl CZ revolves this Wheel a sufficient distance to bring another number ot' the types l of the type-holder operated as above described results from the fact that the impression is given square upon the types, asis the case with ali-ordinary printing-machine.

This cannot be the case wherev thefplaten iscaused'tofvibrate round a fixed center, asin some of themachines originated-forthe'pur--` pose of paging books.

IVhat I claim as myinventiomanddesire to secure by Letters Patent, is-

1. The above-described typefholder, constructed and operating in the mannerV sub stantially as set forth.

2. The peculiar combination andV arrangement of the spring-catch o, the. dog t', the ratchet-Wheelll, and the pawl d, whereby the printing-cylinder is held firmly clamped dur# ingthe operationof printing and is-revolv-edt a sufficient distance to bring anew number over the platen, in the manner set for-th.V

HORACE S. TAYLOR. In presence of- T. D. PELTON, A. L. SoULE.
