REGLATOR FOR THE PEN-BEAM IN RULING-MACHINES.

\ Specification `of Letters Patent No. 8,168, dated June `1'7', 1851.

Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented a new and useful Improvement on the Regulator of the Pen-Beam of the Ruling-Machine; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same,

reference being had to the anneXed drawing, making a partl of this specification and which is a perspective view of the regulator, in combination with aesection of the pen,- beam and ruling-machine. j

The instrument now in use for regulating the position of the pens of a ruling 'machine, consists of a flexible piece ofcopper or brass, permanently secured to the pen beam,

and bent as occasion requires, until the pens are brought into correct position; and in consequence of the necessity of frequently raising and lowering the pens, thisflexible gregulator is subject to `frequent derangement, and the consequent necessity of a troublesome readjustment. `These difficulties are entirely `obviated, bysubstituting my regulator, which is constructed so as to be inflexible and yet capablewof the nicest and most ready adjustment.

A, is a piece ofgrass, bent up at one end in the usual shape (called a foot, `for resting v on the block K, andalso to serve as a means for raising and lowering the pen-beam) and having at the other end a hinge joint (l) connecting it with another piece of brass B, which is made cylindrical and so as to slide accurately through the bearings or posts C, C, C; These posts are connected with, and form part of a plate or base D, which: is permanently screwed to the pen beam E. On the other end of this cylindrical piece B, a screw thread is cut which works in and passes through a revolving adjusting nutor a finger burr F, which is held between two of the posts; andwhen turned, causesthe cylindrical piece B,` to `slide to the right or left within theybearings, as `occasion `may require. l

j Attached to, and forming part of the plate or base, is a projection G, which is connected by a hinge joint (2) with another piece of brass H, which has at its other end, connection with the `iirst mentioned piece A, by means of a hinge joint (3). pen lbeam turns upon a journal or pivot at I, it is evident that, while thehooked` foot of the regulator rests upon the block K, if the linger burr F, is turned, the cylindrical piece B, will slide within the bearings C, C, C, and cause either a depression or elevation of theipens-and also that theraising of the pen beam (by means of a linger applied to the hooked foot of the regulator).

and letting it fall, will not alter the adjustment.

from being moved by accident, after the pen beam has` been adjusted, a small set screw` wheel J, on the sliding piece, is screwed up Now, as the In order to prevent the adjusting wheel F,

I do not claim to be the inventor of the` i 1. I claim the vpieces Gr, II, A, B, in combination with the hinge-joints (l, 2, 3) ar-p.

ranged and combined substantially and for the purpose, as herein described.

2. I claim the sliding piece B, the Vbearson` ings C, C, C, and the linger wheel F, in

combination with the pieces G, I-I, A, uniting by hinge joints, or in any other manner 'substantially `the same; using inthe construction of the whole machine, any material adapted tothe purpose offorming, as herein described, a pen beam regulator, for ruling machines.
