Specification of Letters Patent.

Patented July 8, 1913.

Application filed March 12, 1912. Serial No. $3,382.

To all whom it may concern:

Be it known that I, JOHN J. WARREN, a citizen of the United States, and resident of Brownville, Jefferson county, New York State, have invented certain new and useful Improvements in ire-Guides; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to paper making machinery and is more particularly directed to apparatus for guiding the wire, web or feltof a paper making machine on its rolls in order that it may not run to the ends of the rolls but may maintain an intermediate position at all times.

The invention consists in a device similar in many respects to that forming the subject matter of Patent No. 711139, granted to me October 14, 1902, but diii'ers therefrom in that an improved organization and structure is presented wherein a more compact and simplified structure is attained by mounting the bearing for the roll upon a movable cylinder and in which the cooperating members of the controlling valve in automatically seeking a neutral position cut off the fluid pressure entirely from the actuating cylinder and the packings of that cylinder are consequently relieved from the strains and wear incident tothe maintenance. of high pressure thereon.

Further advantages accrue from the particular arrangement and structure hereinafter described in connection with the appended drawings which illustrate a preferred embodiment of my invention, and in which- "Figure 1 is a plan showing the valve chamber in section; Fig. 2 is a side elevation in which the cylinder and piston are shown in a section taken on line 22 of Fig. 1; Fig. 3 is a vertical cross section taken on line 3-3 of Fig. 1; Fig. 4; is a slm lar view taken on line 4-4 of Fig. 1; Fig. 5 is an elevation of the cylinder showing the valve in a section "taken on line 5-5 of Fig. 3; and Fig.6 is a cross-section of the valve chest taken on line 6-6 of Fig. 1.

Referring to the drawings, one end of the spindle of a guide roll A is journaled ip-a yoke bearing a which is in turn mounted for angular movement upon a vertical pivot a on'the top of a horizontal cylinder 13.

- 0, 0, also carried The cylinder B is provided upon its under side with a dove-tail guide I) which is designed to slide in a dove-tail guideway 6' upon the base plate C of the machine. By movement of the cylinder B upon the guideway I) which lies at right angles to the vertical plane of mounting of the roll A, that end of the roll A supported upon the cylinder may be carried forward or back of its normal position and the roll thereby angularly displaced'so that a belt D of wire, felt, or the like, running thereon and having approached one or the other end of the roll will again ride to the center. As the cylinder A travels in a straight line the pivot a is provided for the yoke bearing a to admit of the necessary varying angular relation between the cylinder Band roll A. A piston E comprises three disks 6 and two cup leathers 6 held between these disks, the whole being mounted between a shoulder f on a piston rod F and a compression nut f screwed upon the end of the piston rod. The piston E is held stationary within the cylinder B as the outer end of its piston rod F is rigidly mounted in a standard 0 upstanding from the base plate C. The piston rod passes througha stuiiing box 9 in a removable head of the cylinder B. A valve chest H cast upon the side of the cylinder B is preferably bored to receive a valve cylinder or bushing 71, having a cylindrical bore. A fiuid supply pipe I enters the valve chest H and communicates with a port z leading into the valve bore at a point midway of its length (see Fig. 6). Two ports 9' and is (see Fig. 5) lead from the valve bore, at points at each side of the middle portion which is occupied by the intake port '5, and to the interior of the cylinder B near the ends thereof. Two exhaust ports I and on lead from the valve bore beyond the ports 7' and is, to a common port 'n and thence to an exhaust pipe N. A valve stem 0- carries two piston valves J and K which, in their neutral position, cover the ports j and 70 respectively. Two end plugs by the valve stem O close the ends of the valve bore at all times. The projecting end of the valve stem 0 is supported in a brack t 0' p jecting from h standard 0. The valve stem 0 is moved longitudinally by a bar P which loosely embraces it between two fast thrust collars p, p, and is further given a slight rotative movement by the oscillation of an arm 40 I to movement by the edge-f the belt. Verwhich tightly grips it. The arm Q. has a ing from the base .to'the crank S which is split jaw which .is drawn together by a binding screw. 0 to grip the stem 0 and by this means the stem 0 may be adjusted with relation to the arm Q both to positionthe arm longitudinally and to rotate the stem to compensate for wear.

A light bar R shown as of wood is mounted transversely of the belt D preferably just under the upper or acting reachof the belt, and one end of this bar is pivotally supported upon a crank movement about a vertical post T upstandplate 0 of the machine. The pivot s which engages with a hole in the crank S, projects downwardly from a box r in which the bar R is adjustably secured by a set screw 7". The bar R is provided with two contact plates U which may be adjustably fixed to the bar by set screws u, and which are designed to provide contacts against which the edges of the belt D may bear and move the bar R transversely of the machine. Movement of the bar by the edges of the belt will impart an angular movement adjustably secured to a second crank V and will, therefore, impart a similar movement to the crank V projecting at right angles to crank S. The crank V is pivoted in one of a number of holes in a bar P and imparts a longitudinal movement to valve stem 0. A rigid arm W depends from the box 9* on the connected by pivoted links to, X and m with the arm Q secured to valve stem 0, insuch manner that the transverse movements of the bar R effect a slight rotative or oscillating movement of the valve stem 0, insurmg the valves free movement in order that they may ofler as little resistance as possible tical pivots between the links w, X and w permit of the longitudinal and oscillatory movements of the valve'stem 0 without interference. The opposite end of the bar R may be mounted in any suitable manner which will admit of its being freely reciprocated, or, if both bearings of the'guide roll with this mechanism, the opposite end of the bar R would then be connected to the corresponding crank S of the duplicate device. Owing to the mover mit of the cylinder the intake and exhaust pipes I and N must be provided with suitable fle'x1ble connections such, as rubber or flexible metallic hose, sliding joints, ortirticulate pipe sections.

The operationis as follows: The neutral position or zpos1t1on of rest is. reached when the valves and K are directly over and closing the ports 1' and 7c and we will suppose the belt D to be running in the correct or central position upon the roll A with the ports so disposed.

if the belt runs to- Now,

which is journaled ward that end of the roll S mounted for angular bar R and is" on the cylinder (see 1) its near edge pressing against the near plate U pushes the bar R in that direction and the motion is transmitted through the cranks S and V' space between valves J and K, into the lefthand end of the cylinder B, whereit reacts on the stationary piston E and moves the cylinder on its guideway to the left. At

the same time an equal quantity of water leaves the right-hand end of the cylinder by the port 70, exhaust ports at and n and exhaust pipe N. This movement of the cylinder to the left follows that of the valves until the ports reach the neutral position under the valves again when the movement of the cylinder stops as no water can then enter or leave. When the cylinder is moved to the left carrying the bearing a the roll A is given an angular relation to the belt B which causes the belt to recede from that end of the roll which it has approached. Whenthe belt approaches the opposite end of the roll, the bar R is moved in that direction and thereverse operation takes place in consequence of the far edge of the belt pressing the far plate U and thereby moving the bar' R in the opposite direction. The plates U are so disposed upon the bar R with reference to the width and normal position of the belt that the belt is kept very closely to its normal position intermediate the ends of the roll. Whenever the bar R is moved and moves the valve, the link u andcrank arm Q provide means for slightly rotating the valve, which frees it from the walls of its cylinder 4 and prevents any sticking which would increase the resistance offered to the "edges of the belt and consequently cause an excessive wear of these edges.

It will be noticed that the several parts. of the device are so correlated that the only place at which the bar R and the guide roll- A do not produce efl'ects which will react upon one or the other of them is that atwhich the belt assumes its normal or central position, and that when the belt is moved to one or the other side of this position the cylinder mustetfect, in seeking the normal closed position of the ports, an angular position of the guide roll which will produce a other side.
