a a. of Fig. 1. Fig. 6 is a side elevation of spring mounted upon the rod 24, which when properly adjusted will hold the 'guide which engages the edge of the making-wire very lightly against said edge, onev end of the spring being connected with the arm 22 and the otherwith the set collar 25', the latter collar being adjustable for producing the desired action in the several parts; 29, a slot arranged longitudinally of the arm 21; 30, an angular arm extending upward from th'e arm 21 and being adapted to be secured thereto at any desired point in its length with the hand-bolt 31; 32, a rod mounted for easy oscillation in the upper end of the arm 33, a holder mounted to oscillate easily upon the rod 32, its normal position thereon being nearly vertically upward; 34 and 34', stems extending upward from the upper end of the holder 33; 35, a guide-plate secured to the stem 34, its inner face being arrangedto engage the edge of Lthe making-wire; 36, the makingwire; 37, a slot from the lower end through the holder 33 in a direction vtransversely of the bore for receiving the rod 32 and extending to apoint a little above the center of said bore; 33, a pin extending out from said. rod upon the side adjoining the making-'wire and being arranged to engage the upper end of said slot 37 and limit the oscillation of the holder toward said wire beyonda nearly vertical position; 39, a spring arranged upon the rod 32 for holding the upper end ot the slot 37 against the pin 38, one end of the spring being connected with the holder and the other with a set collar 40 upon the rod, whereby any desired tension may be given to said spring; 41, an arm secured upon one end of the rod 32 and extending horizontally at right angles therewith; 2, an arm secured upon the rod 24 and extending at right angles with it; 43, a link connecting the outer ends of the arms 41 and 42; 44, rolls arranged upon the stem 34' for use as a substitute for the guideplate 35.

In adjusting the parts for running the guide-roll 6 should be set so that the makingwire will run in about its proper position. The arms 41 and 42 should be so that the outer end of one is directly over the outer end of the other, and the springs should be adj usted, being careful to get the spring 28 with 'only sufticient tension to throw the wire-guide up against the making-wire very lightly, so that the guide can be tilted easily. The

y spring 39 should be given much more tension than the spring 28.

The roll 6 revolving continuously, the action of the crank S and double pawl 13 will be to move the dogs 14 and 14 up and down continuously, and whenever the running to one side ot the normal line of travel of the making-Wire acts upon the guide and by its connections with the pawl brings the dogs upon either side of the ratchet-wheel into engagement with the teeth thereof the turning around of said wheel upon the screw 10 will move the j ournal-box of the roll 6 along upon the way 2, and thereby change the angle of said roll with the making-wire until its posi'- tion is corrected.

Should the making-wire be inclined to run inward or away from the guide, said guide will follow the making-wire by reason of the action of the spring 2S until the dog 14 engages the teeth upon the left-hand side ofthe ratchet-wheel (see Fig. 1) and by the turning of said wheel upon the screw-shaft 10 moves the journal-box 5 until the angle of the roll with the making-wire is changed and said Wire assumes its proper position.

Should the making-wire run too much outward and bear too hard against the guide, the spring 39 will then come into use and allowr the guide to swing outward to a greater distance than it could if said spring were not so applied. The bearing of the making-wire against the guide beyond a determined amount will swing it outward and through the action of connecting-links27 and 43 bring the dog 14 into engagement with the teeth upon the right-hand side of the ratchet-wheel and, turning it upon. the screw-shaft, will change the angle of the making-Wire with the roll .until said wire assumes its proper position, when neither ot the dogs will engage the teeth of the ratchet-wheel.

The making-wire often runs outward to one side of its proper line ot' travel faster than the action of the dogs upon the teeth of the ratchet-wheel will turn said wheel and move the journal-box for correcting the running of said wire, and the spring 39 allowingthe guide to swing outward permits such faster sidewise movement without any danger of so great a pressure ot' the edge of said wire against the face of the guide as to cause said edge to buckle and become broken.

The particular object of the slot in the holder 33 of the pin 38 and spring 39 is to permit this faster movement of the making-wire outward against the guide without the pressure of the edge of the wire against the guide that would occur if said spring were not thus arranged, and thereby permitting a plate or vertically-arranged guide to be used for guiding the making-wire.

Side plates, one on each side of the makingwire, have long been in use; buttheir excessive wear upon the edges of the Wire has made their use objectionable; but with this improvement and the use of the guide upon but one edge of the wire, which is all that is required when the spring 39 is used, this excessive Wear of the guide upon the edge of the wire, which is caused principally by the friction of the heavy bar for connecting the two guide-plates, is avoided and the use of a vertically-arranged guide made successful.

It will be obvious to practical paper-makers that the holder 33, mounted upon a rod for oscillation and being provided with the slot 37, pin 3S, and spring 39, modified to suit the conditions existing relative to any particular paper-makin g machine,are adapted to be used with guide-plates located one on each side of IIO IIS d the, making-wire and being connected to one another by means of a bar extending across said machine; but that plan is not advised, as it involves unnecessary expense in construction, in operation, and in wear upon the edges of the making-wire. I

In usingthe rolls 44 instead of the plate for guiding the wire there may be one or any number which seems desirable in any particular case.
