HENRY HOCHSTRASSER, OF PHILADELPHIA, PENNSYLVANIA.

MACHINE FORv PAGING BOOKS.

Speccatonof Letters Patent No.

To all 'whom t may concern Be it known that LHENRY Hoorrs'rnassnn, of the city and count-y of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Paging-Machines for the Purpose of Paging Books; and I do declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had t-o the annexed drawings, making a part of this specification, in which- Figure 1 is a perspective view; Figs. 2 and 3 sectional drawings. 1

'Io enable others skilled in the art, I will proceed to describe its construction and operation.

I construct the body of my machine of wood somewhat of the form of a desk or table, (A) with the bottom extended to the left (B B B) for the purpose of receiving the shaft upon which the wheel (or form) slides and turns. The wheel is made of metal and of a spiral form, (C Fig. l) for the purpose of paging an indefinite number of sheets. This is one advantage my improvement has over the machines now in use as they have to use several forms (wheel chains7 &c.,) to complete the paging of one book. At the outer edge of the flange of the form there are spaces cut; (D) these spaces correspond with and are the same distance apart as the type on the surface of the fiange. These spaces have a two-fold use; one is they will not allow the wheel (or form) to move any farther than is requisite, as the roller (E Fig. 2) upon which the liange of the form rests partly enters the spaces, and holds it in that position until itis moved by an adjustable escapement (F) acted on by a treadle (G Fig. l) with the foot. The escapement is another advantage I have, as it matters not how rapid the machine is worked the momentum cannot throw it farther than is necessary; as is the case with the ratchet wheel, as the escapement with unerring certainty moves it just so far and no farther. The adjustable part of the escapement working on a center is always when out of the spaces, at an angle (I Fig. 3) with the next succeeding space.; and being of a wedge shape at its point forms an inclined plane upon. which t-he sides of the spaces bear; and by its upward motion moves the form the distance of one space only. When it moves downward in the act of printing, the upper part of the escape- 11,728, dated September 26, 1854.

ment (J Figs. 2 and 3) enters the space at the saine time the adjustable part leaves it and prevents the form being moved while in the act of printing. At the upper end of the stationary part of the escapement an arm is attached (K Figs. 2 and 3) by an adjustable screw nutso that it can be raised or lowered at pleasure. This is directly over the type and in descending presses the leaf on the type and prints the even numbers; and there is a corresponding arm (L Fig. 3) which at the same time moves upward and presses against the type on the lower surface of the flange, that prints the odd numbers, so that two numbers are printed at the same time.

The spiral wheel (or form) moves on a vert-ical shaft (M Fig. l) and has a joint at its lower end (N) with a stop. And a brace (O) proceeds from the main body of the machine and receives the upper end of the shaft (P) sothat when the spiral form has run down, or as far as requisite by releasing the brace the form can be removed away from the escapement,and other machinery,

and raised to its first position in readiness Motion is given to the machinery by pressure of the foot upon a treadle (G Fig. 1) to print, and by a counter weight (Q Figs. 2 and 3) at the opposite end of the treadle an upward motion is given which causes the escapement to move the form and inking rollers (R R Fig. 2). At the same time the rollers move they ink the type. An iron shaft proceeding from the treadle connects with a crank (S Figs. 1, 2 and and gives the requisite motion to the connecting rods which works the escapement, the arms, the inking rollers, the smut, &c.

The type are to be riveted on the flange in sect-ions containing several numbers in each section; or to have type with a face on each end and to be placed in square holes in the flange with the upper part of the holes largest and the type to correspond so they will not drop through. In this way they will adjust themselves to the arms in the act of printing; and can be easily placed, and replaced.

N. B.-Tlie vertical shaft which supports the form has a spiral groove which corresponds with the spiral of the flange; and if desired can oer used instead of the above de- Frst, the adjustable escapement F; and erbed. I adopt the roller as preferable, as second',A the roller E in connection with the it matters not how untrue the form may be spaces substantially as herein described.

it will cause the type always to be n their HENRY HOCHST'RASSER. 5 proper place. Witnesses:
