TO ALL WHOM IT MAY CONCERN:

Be it known that I, W. O. HICKOK, of Harrisburg, in the county of Dauphin, and State of Pennsylvania, have invented a new and useful Improvement in Paper-Ruling Machinesyand I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference -being had to the accompanying' drawings, making a part of this specication, in which-- l Figure 1 is a perspective view of one of the said improved machines broken away across its middle in order to narrow the figure. Y

Figure 2, a. vertical transverse section of part of the same cut through the centres of the turning points of the pen-beam; and

Figure 3 a vertical longitudinal section of theisliding standard, which supports the further end of the pen-beam.

Like letters of reference indicate the same parts when in the different `iigures. f

Although the pen-beam of paper-ruling machines has been supported upon standards and bearings made adjustable-by means of slots and screw-nuts, or by means of thumb-and-inger screws, in combination with slides and'jam-nuts, for the purpose of enabling the attendant to adjust the pen-beam with accuracy and facility, to suit defects in the form of the paper, many of the reams in a lot of paper being often trimmed or cut at irregular angles, yet the diierent devices heretofore produced for the purpose are still more or less defective, especially in that they do not provide against the very objectionable binding or strained result upon the beam and its bearings, arising from the movement ofthe nearer one of the supports ofthe pen-beam, while the otherl or further one is stationary, relative conditions which are almost constant.

The object of my improvement is to avoid this objection; and my invention consists in the 'construction and application of' a vperforated ball in combination with a sliding stem, so as to afford a ball and sliding joint, for the further end of the pen-beam,substantially as hereinafter described.

My invention also consists, in combination with the'said ball and sliding joint, the employment of a solidball joint, for supporting the nearer end ot' the said pen-beam, substantially as hereinafter described; and my invention also consists, in combination with the said two ball-joints, the application of the standards, so that they can be slid longitudinally along on the table or frame of the machine with greater accuracy and facility as the required adjustments of the pen-beam may from time te time require during theoperation of the machine,

substantially as hereinafter described. v i v Referring to the drawings, A is the pen-beam; B B', the sliding standards; C C', fixed supports for the sliding standards; D D', the ball-joints; E E', stems, which connect the respective ball-joints and standards to the twoy'ends of the pen-beam; and F, sections representing the table or frame of the machine. n

The standard B consists of a post, b", having a dat foot, 6"', whereby it is supported-in a verticall position, and so that i-t can be slid along'backward and forward on its base, C, which is fixed permanently `to the frame, F, of the ruling-machine. V

Projecting on the front side of the post b" there are two fixed lugs, b* through both of which a thumband-finger screw, g, is secured, so that it can be rotated without screwing inthe said lugs. Between the lugs b4 b5, a block, g', is iitted to slide accurately up and down the post b", when tbe screw g, which screws through it, is rotated accordingly. Transversely through this sliding block g', another thumb-and-finger screw,vg", works, and which is ittedwith ajam-.nut,';q"', at the outer side oi' the post b", whileits inner end is finished` with a bau, g3 (see ng. 2.)

The rear end of the base, C, of the post b" hns an upright,'c", in which a thumb-and-nger screw, c'", is secured in a horizontal position by a head und jam-nut thereon, so that it can be rotated without screwing in the upright, c", and on the slide b"' there is a corresponding upright,i 6, through which the said screw 0"' is caused to move the slide in adjusting the standard B', (see fig. 1.) V'

On that end of the pen-beam A, which connects with the bali y', there is fixed a two-part clamp, a' a",

the part a." being detachably secured to the parta'. Between these two parts a spherical Vcavity is made for the reception of the ball g4 on the end of the screw y", so that the said cavity, with the said ball on the end of the screw g", will form together the ball-joint D, a suflicient space being made around between the screw-stem and the outer opening of the cavity to allow the required motion in the joint, as'will be hereinafter referred to. The standard B'. is supported in a vertical position, and so that it can be slid backward and forward in a fixed base, C', by means of a screw, 0"', precisely in the same form and manner as upright, B. Projecting from the upper end of the post b" thereof there is a boss, b', through which a screw, H, is caused toslide accurately up and down by means of a. thumb-and-finger mit, h', above theboss 127, ajat'n-nut, h", being applied below the boss for the purpose of fixing the said screw when necessary. l

The lower end of the screw H has iixed to it a two-part'clamp,.h"', the two parts of t" being detachably secured together by screws. Between the two parte of the clamp t" there is a spherical cavity, in which a perforated ball, t, is accurately fitted to rotate, and, fixed to the further end of the pen-beam A, there is a projecting stein, 11"', which accurately fits through the perforation in the ball h4, yet so that the said stem can be slidalong within the ball, suicient space being made around between the open edges of the spherical cavity and the stem to allow the required motion of the ball-joint, as will hereinafter be referred to.

The projecting stem a"' is fixed in a boss on a plate, a4, which plate is fixed on the cnd. of the beam A, substantially as represented in fig. 2. d i l l It will be readily seen that, by means of the ball-joints D D' andsliding standards'B B', constructed and arranged in combination with the pen-beam and the frame or table of the machine, as described, the said penbeam, with its pens attached, can be instantly adjusted with facility and perfect accuracy, to suit any inequality in the paper passing under them, and without any binding or straining, because a rotary motion given to the screw g" will give an exact longitudinal motion to the pen-beam. t A like rotary motion given to either of thc 'screws g and L will give an exact vertical motion to either end of the pen-beam.' A like rotary motion given Ato either ofthe screws, c", of the slides, will give an exact horizontal motion to the said beam, 'and therefore,

the beam being suspended by the ball-joints D D', any movement required in the said penbeam canbe instantly and accurately given with` facility, and without causing any bindingor strainingv Whatever at any part of the beam. t

--It will also be seen that the manner in which the axis or stem, a', of the further end of the pen-beam is applied thereto,` is an improvement of importance, as it affords, not only a more substantial axis, but admits of greater accuracy in itsapplication to the beam. p

Having thus fully described my improvement, -what I claim as new thereinV of my invention, aud desire to secure by Letters Patent, is confined to the following, viz:

1. I claim suspending the peu-beam of a paper-ruling `machine by 'means of the ball-joints D-and D', in combination with sliding standards, B and B', operating together, substantially as and for the purpose described.

2. I claim the ball-jointD',4consisting of the socket It* and the perforated ball therein,`in combination with the stem a'" on the end of the pen-beam, thesaid parts operating together substantially in the manner described.

3. I claim,in combination with the peu-'beam A and sliding ball-joint D', the solid ball-joint D, consisting 4of the sphericalcavity within the clamp a' off'lon the end of the pen-beam A, and the solid ball g4 on the end of the screw g", the said 'parts being constructed' and arranged to operate substantially as and for the purpose described. i, i

4.' I claim, in combination with a pen-beam, A, suspended upon the bal1j0ints D and D', as described, the sliding standards B and B', operated by means of their respective screws .c" 6"', substantially as and 'for the purpose described. `l l p v v 5. I claim, in combination with the pen-beam of a ruling-machine, the stem a', constructed and applied substantially as andfor the purpose described. Y.

O. HICKOK.
