IMPROVEMENT IN PAPER-RULING MACHINES.

Specification forming part of Letters Patent N 0. 123,309, dated January 30, 1872.

To the Commissioner of Patents:

Specification describing certain Improvements in Paper-Rulin g Machines, invented by J AMES TREGURTHA, of Oharlestown, in the county of Middlesex and State of Massachusetts.

The first part of my invention relates to the combination of a cam-shaft, ratchet-sector, and pawl with the paper-receiving box of the machine, in such a manner that the inclination of the said box can be readily and quickly adjusted and varied, as occasion may require, during the operation of the ruling-machine the object of this part of my invention being to enable the attendant to adjust, from time to time, the height of the upper surface of the growing pile of ruled paper sheets deposited in the box, to favor the deposit thereon of the succeeding sheets. The second part of my invention relates to the combination of a supplementary pen-bearin g and cam-shaft between the driving-cylinder and the usual pen-bearin g roller, in such a manner that the said supplementary pen-bearing can be readily raised and retained so as to be in contact with the under side of the moving cloth above, as occasion may require; the object of this part of my invention being to afl'ord a proper support to the moving cloth for the points of a series of pens in a supplemen tary pen-beam, not shown, to'be applied as occasion may require.

Figure l is a side elevation of a pen rulingmachine embodying my invention. Fig. 2 is a transverse section of the frame on the dotted line V W of Fig. 1, and showing a front view of the inclined paper-rulin g box and its paperlaying bar, with a side view of the adjusting ratchet-sector and pawl. Fig. 3 is a view of the under side of the paper-ruling box, with its adjusting cam-shaft as applied thereto. Fig. 4 is an end view of the supplementary pen-bearing and its adjusting cam-bar, as in its supporting or hearing position in contact with the movin g cloth.

The paper-receiving box A is supported in the usual inclined position, with its lower end resting upon the floor and its upper end resting upon the cam-shaft B, the hooks a and pins to preventing it from sliding off or becoming detached from the said bar. There are two like cams, b b, fixed in the shaft B, so as to operate against the under side of the box A, and the shaft B is operated, for the purpose of raising and lowering the upper end of said box, by means of a handle, I), on a ratchetsector, b, which is fixed on the end of shaft B. A pawl, O, traverses the teeth of the ratchet-sector b and supports the shaft B, while its cams b I) bear upward against the box A, and thus the top surface of the growing pile of paper in the box can be readily kept at a proper height to receive upon it the successive sheets delivered by the moving cloth D. The paperlaying stick or bar E is in two pieces, adjustably connected together by means of a slot, 0, in each piece, and a set-screw, e, the under piece being adj ustably secured by another set-screw, e, to the usual slotted bar 6 and consequently the stick or bar E can be readily elongated, to suit the size of the paper to be laid, without causing its upper end to come in contact or interfere with the moving cloth above.

The device for supporting and raising and lowering the pen-beam F consists of a vertically-moving block, G, which is under-cut so as to present two separate inclined planes, g g, each plane being divided by a longitudinal groove in the middle of the under side. It is connected by a tie-bar, g, pivoted on each side to a stationary block, H, on that part of the frame of the machine, so that the said block G can be freely raised and lowered to raise and lower the pen-beam F, the arm f of which rests upon the said block G. The slide I has its inner end under the block G, its outer end serving as a handle, 1', whereby it can be pushed further under G in order to raise the latter, or pulled outward to lower it. The sides of the slide I are recessed to receive the inclined-plane projections of the block G when the latter is down, as in Fig. 1, the thin portion between the recesses in the slide I passing up into the longitudinal groove in the block G when the latter is let down. The side projections 4 and 5 of the slide underrun the inclined planes g g, respectively, of the block G, and thus elevate the latter when the slide I is moved inward, as represented by the dotted lines thereat.

For the purpose of enabling the attendant to raise and lower the pen-beam F while standing at the front end of the machine, a stiff rod of wire attached to the slide extends forward and projects through the postKof the machine, so as to afl'ord a handle, i, thereat, whereby the slide can be readily moved inward and,

outward to lower and raise the block G7 and consequently the pen-beam.

The supplementary pen-bearing L (see Fig. 4) is attached to the frame by a tie-bar, l, at each end, and rests upon a cam-shaft, M, across beneath the moving cloth N, in such a manner that by partially rotating the cam-shaft by means of the handle m the said supplementary pen-bearing L can be raised and supported at any time so as to form a bearing under the said cloth for an extra series of pens whenever it may be desirable to apply the same to that part of the machine.

I claim as my invention-- 1. In combination with the paper-receiving box of a paper-ruling machine, the cam-shaft B, ratchet-sector b', and pawl 0, arranged to operate together substantially as and for the purpose hereinbefore set forth.

2. The combination of the supplementary pen-bearing L and cam-shaft M, constructed and arranged to operate together upon the moving cloth N, substantially as and for the purpose hereinbefore set forth.

JAMES TREGURTHA.
