To all whom it mrtycmtcern:

Be it known that we, WILLIAM M. GILBERT,

dentsof Neenah, in thecounty of Winnebago and State of Wisconsimhave invented anew and useful Improvement in ire or Felt -Guides of Paper-Making Machines, of which the following is a specification.

1 Our invention relates to, mechanism for and it consists of mechanism for producing saidresult by the revolutions of said carrying-rolls, as will be herein described.

Figure 1 is a plan View of a small section; of each endof the wire or felt carrying roll of apaper-making machine, the journal-bearingswhich support the same, and the mech anism for moving the left-hand end of said roll forward or backward. 'For want of room the right-hand end of the roll laps over the base of the mechanism for moving the lefthand end of said roll. Fig. 2 is an elevation showing the rear sideof the roll-sections shown in'Fig. 1 and an end view of the stand upon which the mechanism' for moving the left-hand end of the roll forward or backward is mounted. Fig.8 is a vertical sectionlongitudinally of its shaft of a beveledface. pulley which enters into the construction of the mechanism. Fig. 4 is afront elevation of the mechanism for moving the lefthand end of the roll forward or backward and showing also the left-hand end of said roll. Fig. 5 is a transverse section of the journal-boX for supporting the left-hand-journal of theroll as it appears in looking to the left of the line a a of Fig. 2. elevation of a ratchet-wheel, its side-inclosin g ears,and the movable journal-box support for I end of the wire and felt carryported and slides. .with ears 20, which depend upon each side 85 wheel.

Fig? dis a side ing supported in the journal-box 3, which is mounted to turn horizontally in its supporting-stand 4, and the journal-shaft 2 of the jright-hand end being arrangedtoturn in a 5 5' like manner in its supporting-stand 4, 5 be- ;ing a block under stand 4 for bringing the .end of the roll to a corresponding height, and .4 being bolts for securing the stand 4 in position. I

I 6 indicates the bed-piece of the stand 7, which stand is arranged to slide toward and from the end 2 of the roll, the stand being held in position upon the bed-piece and guided in its sliding movement by gib s 8 8, the latter gib being detachable and provided with bolts 8 for adjusting its position upon the bed -'piece. The bed-piece is provided with ears 6, bywhich the bed-piece may be secured upon the bed-timber 1.

9 is a screw arranged across the bed-piece,

revoluble in the boss 10, which boss projects 'upward from the piece 6 between collars 11 11" on the screw, the screw engaging the nut 12 and being provided with a crank and handle 13, by means of which the screw may ,be turned and the stand 7 moved transversely of the paper-machine. I

The stand 7. consists of its base 14, ends 15 and 15", top piece 16, having the way 17,, upon which the journal-box stand iis arranged to slide within the groove 18, and ashelf 19,'upon which the lower end of the stand 4 is sup- The stand 4: is provided of the ratchet-wheel 21 in close connection with it and join together in the rear of said The wheel is internally threaded, provided with teeth 21, and mounted upon the screw 22, the screw being secured ina 9o fixed position in the ends of the stand 7, so that by turning the wheel upon the screw it is carried along toward one end or the other of the screw, and the supporting-stand 4 is moved along upon the way 17 and shelf 19,

and the end 2 of the roll thereby moved either in or opposed to the direction in which the wire or felt is running, said direction being indicated in these drawings by the arrow above, Fig. at. Upon the outer end of the journal-shaft 2 a wheel 23 ismounted, it being provided with v The left-hand end of the wire or felt carryacrank-pin 24, from which is suspended by the link the dog-holder 26, said holder being connected at the point of the pin or screw 27 by means of the link 28 with a pin 29,

which extends out from the arm 30 of the supof the shaft 2 is made to reciprocate in a nearly vertical direction.

Below the point 27 the dog-holder branches to the right, 26", and left, 26, of the ratchetwheel and is provided with enlargements 31 31 and dogs 32 32, which dogs are adjustably secured in said enlargements with set-screws 33, and above the point 27 the holder is curved for clearing the crank-pin and upper end of the link 25 and is then extended upward vertically, 26, and provided with a slot 34.

ing roll terminates at the dotted line 35, (see Figs. 1 and 2,) its shaft being enlarged over its journal diameter, as shown by dotted lines 36," so that the roll is held from endwise movement in its journal-box 3 between said enlarged portion and the wheel 23, and any movement of the stand 7 transversely of the paper-machine will carry the roll with it, the right-hand-end journal-shaft being made suf-v ficiently long, as shown, for allowing the necessary endwise movement for suiting the position of the roll to the running of the wire or felt.

Upon the left-hand end of the roll from the line 37 a band 38 of some suitable flexible material, as leather, is secured, it projecting over the end of the roll from the dotted line 35 to the end 38. 39 indicates the wire or felt in Figs. 2 and 4 over said band, they being omitted in other figures for clearness of illustration.

Supported upon the journal-box 3 by the bows 40 and mounted in suitable journalboxes 41 within said bows is a shaft 42, having upon its inner end a beveled-face pulley 43 and upon its outer and awheel 44, having a crank-pin 45 extending out from it and entering loosely into the slot 34 of the dogholder. Mounted upon the shaft 42 is a collar 46, adjustably secured thereon by means of a set-screw 47, having one end of a coiled spring 48 secured to it, the spring being arranged around the shaft 42 and its other end resting against the outside of the journalbox 3.

The pulley 43 is arranged at the end of the wire or felt carrying roll with its top surface bearing up under the flexible band, so that the outer end of said beveled-face pulley will raise said band higher than the top of the roll and form an incline from the end of the roll to the outer edge of the band, along which the edge of the wire or felt will travel whenever it is inclined to run too far outward beyond the end of the roll. Thewire orfelt in running up this incline is caused by it to bear upon the band and said band to bear upon the top surface of the beveled-face pulley and cause it to oscillate in the direction in which the wire or felt is running. The oscillation of the pulley will oscillate the wheel 44 and throw the crank-pin 45 against the right-hand side of the slot 34, and consequently swing the dog 32 into engagement with the teeth upon the right-hand side of the ratchet-wheel, Fig. 4, turning said wheel as the dog-holder is reciprocated and moving the journal-box 3 toward the left, and consequently changing the position of that end of the roll toward the left and causing the wire or felt to run toward the end 2.

For causing the wire or felt to run toward the beveled-face pulley the action of the spring 48 is reliedon, the spring being coiled in the proper direction for oscillating the beveledface pulley in an opposite direction from that in which the wire or felt is running. The crank-pin 45 is consequently thrown against the left-hand side of the slot 34, and thereby swings the dog 32 into engagement with the left-hand side of the ratchet-wheel and turns.

it upon the screw 22, so as to move the journal-box 3 in opposite direction from that in which the wire or felt is running, and consequently causing said wire or felt to run toward the pulley 43.

The guide herein shown is one that is termed a left-hand guide that is, one adapted for the left-hand side of the wire or felt as it is running from the observer. It can be adapted for the right-hand side by slight changes in its construction, such as extending the slot 34 farther upward and placing the crank-pin 45 above instead of below the center of the shaft '42, as shown in dotted lines in Fig. 2, coiling the spring 48 in the reverse direction and arranging the lower end of said spring upon the opposite side of the journal-box 3, as shown in dotted lines in Fig. 5.

In describing this invention a beveled-face pulley 43 is named as an element and is shown in the several figures; but it should be understood that a segment of a pulley 43, as is shown by heavy lines in Fig. 4, or the entire pulley, as is shown by both heavy and dotted lines in Fig. 4, is within the scope of our invention and is included in the term beveled-face pulley. A small section of the upper part of the pulley is all that is required for throwing the dogs into engagement with the ratchet-wheel upon either side,

. butfor reasons obvious to a mechanic in their The flexible exten- ICC terrace;

over the endof the roll is preferable, the slight difference in construction being that in using the band the top of the small end of the pulley is placed below the-top of the roll the thickness of said band, while in dispensing with it the tops of the pulley and roll should be flush with each other.

a The upper end of the link is provided with a slotted aperture 49 instead of a circular bore for the purpose of the engagement therewith of the crank-pin 24, so as to prevent any liability of the binding of the pin by reason of the action of the two links which control the movements of the holder 26.

Attached to the end 15 of the stand 7 is a flexible connection 50, which extends to and is connected with the left-hand dog'holder for the purpose of limiting the movement of the dog-holder and journal-box 3 toward the right beyond a predetermined limit for-preventing injury to any of the parts.
