PEN-BEAM STANDARD FOR RULlNG-MACHINES.

, SPECIFICATION forming part of Letters Patent No. 284,666, dated September 11, 1883.

Application filed January 9, 1883. (N0 model.)

To all whom it may concern Be it known that I, EDWIN J. PIPER, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Pen-Beam Standards for Ruling-Machines, of which the following is a specification. v

This invention relates to improvements in paper-ruling machines; and it consists in an improved construction of the pen-beam standards therefor, the object being to provide standards for supporting the saidbeam, which, more freely than heretofore, permit of a gravity adjustment of the beam and pens to the face of the paper upon the apron, and which embody improved means for securing and retaining said beam in proper position and for adjusting it in any required direction.

In the drawings forming part of this specification, Figure 1 is an elevation of said penbeam standard embodying my improvements. Fig. 2 is also an elevation, but partly in see-. tion. Fig. 3 is a plan view of the standard, partly in section, and one end of the pen-beam, the latter and the standard being shown connected together as they are when in use.

In the drawings, A is the standard a indicates the ordinary adjustable standard-base, by which said standard is secured to the frame of the ruling-machine. An adjusting-screw, a, passes through the upper end of the standard and projects downward a certain distance within the latter, which is made hollow, as shown. Said screw ais provided with a groove around it near its end, (similar to that in bolt m, Fig. 1.) A swivel-bolt sleeve, e, of an inverted-T shape, is attached to the lower end of a screw a, the vertical arm of sleeve 6 being perforated to receive the lower end of said screw, and a pin 18 placed transversely through said arm and through said groove in said screw,

' whereby the latter and said sleeve are secured vided with a head, d, which is perforated in a line across the axial line of said bolt.

The aforesaid standard A is provided with oblong vertical openings 2 2 in opposite sides thereof, as in Figs. 1 and 2. The said swivelbolt 1) bears upon it two curved-faced washers,

a 11., adapted to fit against the sides of standard A and over said openings zz therein, bolt b passing through the latter and sleeve 6. A nut, 0 is fitted to bolt b. A pen-beam bolt,

an, provided near one end with a circular groove, w, is screwed through the head (I of the swivel-bolt b, so that the latter and bolt m occupy positions at right angles to each other. Set-nuts o and a are placed, respectively, on bolts m and a.

The pen-beam B is provided at each end I thereof with abolt-arm, t, which projects from 6 5 the end of said beam, and is provided with a suitable socket to receive the grooved end of the bolt m. A pin, 71, is passed through said arm t one side of its center, and through said groove win bolt m to one side of the center of the latter, whereby said bolt, while being secured to said arm, is allowed to turn freely therein as it is operated in the head (I of bolt 1).

The usual adjustingscrew, 0, is employed for sliding the base 0 upon its bed and retain-' ing it in proper position.

The ordinary pen-beam handle, I), for lift ing the pens f from the paper by swinging the bar B on the ends of bolts m, is secured to said bar. Said handle is also provided with the So usual adjusting-screw for regulating the bearing of the points of the pens upon the paper. The pens f are secured in the clamp 7c in the ordinary way. I

The operation of my improvements is as follows: The operation of bolt at through the head (I of bolt 1) provides for adjusting bar B in the direction of its length, to bring the points of the pens f to a proper position on the paper. The swivel-bolt I), being free (when nut o is unscrewed) to turn in sleeve 0, permits bolt m to adjust itself relative to arm ton bar B. The connection between sleeve 0 and the lower end of screw (0 is such that said sleeve is free to oscillate thereon to a certain degree, and the openings 2 z in the sides of the standard A permit the bolt 7) to oscillate with said sleeve, and by-screw a bolts I) and m are raised and lowered and secured at any desired position, and by lowering sleeve 0 to such a point as the weight of the pen-bar B may force it, and by unscrewing nut 0 to free bolt 7), the

parts to which said bar are attached are given consisting of the standard A, having perforat- 10 such a free movement as prevents them from ed sides, the sleeve e, screw a, and the bolts 12 interfering in the least with the self-adjustand m, combined and operating substantially ment of said bar and pens to the surface of the as set forth.

5 apron and paper after which by screwing up nuts 0 and 'v, the supportingparts of the bar EDWIN PIPER B are rigidly secured to said standard. \Vitnesses:

What I claim as my invention is WM. H. OHAPIN, lhe Within-described pen-beam standard, HENRY KNOX.
