Patented Sept. 14, 1937 UNITED STATES PATENT OFFICE DISTURBANCE ACTUATED VALVE Application May 25, 1934, Serial No. 727,468

4 Claims.

This invention relates tomeans for treatment of sheet material, as paper, or the like, and has special reference to the treatment of such material in a printing press after the material has been printed, as for drying it and for removing the static charge therefrom.

I am aware that such treatment of material is not new but my invention aims to provide an improved means for that purpose having, among others, the advantages hereinafter described.

In the drawings of one embodiment of my invention selected for illustration and description,

Fig. 1 is a side elevation of a portion of a conventional form of printing press with my im- -proved sheet treating means thereon;

Figs. 2, 3, 4 are vertical sectional views respectively showing the fuel supply valve and its operating means in different positions as hereafter described;

Fig. 5, a horizontal cross-section on the line 5-5, Fig. 2, of the valve body; and

Fig. 6, a detail side elevation of a modified form of valve actuating means, showing the housing in section.

Referring first to Fig. 1, there is shown aportion of the forward end of a conventional printing press frame I, with a rail 2 on-which reciprocatesa sheet-conveying carriage 3; which is operated by suitable means including a link 4 from any convenient portion of the press,- not shown.

The printed sheet from the cylinder, not shown, is broughtforward by the carriage 3 and as it returns the sheet is dropped upon horizontal supports 5, one being shown, the forward edge of the sheet beingheld in'proper position by the stop 6 which drops from the carriage at the proper time as the carriage reaches the limit of forward travel.

As the carriage starts on its return trip, a stop 1 automatically rises into position behind the sheet edge to prevent any return movement by the sheet, and the stops 6 rise and permit the sheet to drop from the supports 5 to a lowering table or other support 8 below.

The sheet treating means may be mounted upon any one of several parts of the carriage, that will position the treating means near the sheet, as desired, and herein I have shown it as mounted upon and positioned adjacent the forward end of All this is conventional construction and forms no part per se of my invention.

Referring now to Fig. 1, my novel valve construction, which is primarily the subject of this application, is shown as comprising a valve housing 9 of any convenient shape connected at some point, herein Fig. 1, its top, by a fuel supply pipe l with a suitable source of supply, not shown. At any suitable point, herein its base, the valve chamber may be connected by any suitable means, as a neck Illa, with a mixing chamber I I of conventional construction, which, in turn, Fig. 1, is

connected to a suitable fuel burner l2, dotted lines, which may be simply a section of pipe of proper dimension, provided with a plurality of outlets, not shown, for the fuel, as gas, and positioned adjacent the forward edge of the carriage 1 3. No novelty is claimed in the burner proper.

My novel valve construction, Figs. 2, 3, provides the housing 9 with anipple or other suitable member l3' with a cylindrical valve body I 4 therein,

Fig. 5, having a plurality of ports or inlets I5 therethrough, see also Fig. 5.

The central inlet or port receives a valve stem IS, with a head I! which overlies normally the remaining ports and closes them; At its lower end the stem l6 carries a nut I8or other suitable Movement of this pendulum, both as to direction and distance from normal position, is regulated by set screws 23'; 24 threaded into the side wall 22 of the housing. The pendulum carries above its pivot point avalvelifting plate 25.

The housing, Fig; 1, is providedwith a pilot light 26, if desired, which is usually kept lighted. During the printing or other treatment of the sheet material, the valve I6 is usually closed, as in Fig. 2.

When the carriage moves forward with the 40 printed sheet, tothe right, Fig. 1, disturbance of the equilibrium of the pendulum 20, as by the starting of the carriage, would tend normally to cause it to swing to the left, Fig. 2, dotted lines, and by the contact of the plate 25 with the member [8 open the valve to admit fuel to ignite the heat supplying burner, which is not generally desired, and this is prevented to the extent desired, by the set screw 23, adjustably positioned to that end. It is not usually desired to apply heat from the burner during the forward travel of the carriage as it might injure the paper, and is an unnecessary expense. The adjustment as shown, I Fig. 2, permits slight swinging of the pendulum to the left, if desired, to obtain momentum for 50' the cylinder raising mechanism, which is reciprocated by any suitable means as a disk 29, through:

the swing to the right on the return of the carriage to be described.

When, however, the carriage starts its return travel to the left, the disturbance created by the starting of the carriage causes the pendulum to swing to the right, dotted lines, Fig. 3, and this is permitted to the desired extent by the position of screw 24, and the Valve is raised as already described, Fig. 3, permitting gas to' enter the housing and thence pass to the mixing chamber II and ignite the burner and supply heat to dry the printed sheet upon the delivery table 8 as the burner passes over it during the return move ment of the carriage.

Thus heat is applied to the sheet only on the return trip of the carriage and burner, and in the quantity or degree permitted by the opening of the valve to the extent allowed by the position of the set screw 24.

If for any reason it should be desired to supply heat during the forward travel only of the carriage, then the movement of the pendulum 20 is controlled to that end by setting the adjusting screw 23 as in Fig. 4, so that the valve will be opened at the beginning of the, forward movement of the housing to the right, by the swinging of the pendulum to the left, dotted lines, Fig. 4, and closed during the return travel by the position of the screw 24 preventing swinging of the pendulum to the right.

Should it be desired to have heat applied during the travel of the carriage in both directions, then the screws 23, 24 should be adjusted to permit the pendulum to swing to' the extent necessary to open the valve l6 when the housing travels in either direction. As a rule, it is not desired to apply heat to the sheet while the carriage is moving both ways.

While this operation of applying heat to the :paper has been performed before, the means employed forthat purpose have been complicated, expensive and unsatisfactory in certain respects, and hence I have conceived the present improved construction. i

If desire-d for any reason, either from the different construction of thepress or otherwise, the valve housing 9, with the supply pipe I and burnerv pipe 21, Fig. 6, may be mounted elsewhere on the press, as a reciprocating bar 28, part of the pawl 30 seated in a pocket 32 in the edge of the disk. 7

The valve in this case comprises any suitable construction, as a ball 3|, carried by the pendulum itself, in a pocket 32 in the pendulum and adapted to seat in the nipple 33 of the outlet pipe 21 when in its forward, right-hand position.

In this case the housing is rocked forward and back, with the pawl 30 by the disk 29 each time the cylinder is raised and a sheet fed forward, and at this time the valve is closed, but each time the cylinder is dropped to print, the housing is rocked. rearwardly, to the left, Fig. 6, dotted lines, the pendulum is disturbed and swings to the left, the valve is opened, and fuel supplied to the burner through the outlet pipe 21 for drying'the printed sheet.

Applicant is not restricted to the precise embodiment described and illustrated herein, and which is more particularly pointed out in the following claims.

I claim:

1. A disturbance-controlled valve, comprising a valve housing having an inlet port, an inlet closure therefor with ports in the closure member, an outlet port, a pendulum with a valvelifting member thereon in the housing and controlling by its position the action of the closure, to effect and discontinue communication between the ports. I

2. A disturbance-controlled valve comprising a housing, a valve stem therein, an adjusting member thereon with ports registering with passages through the valve, a pendulum in the housing, and means for electively controlling by the pendulum the action of the valve stem when the housing is disturbed to effect and discontinue communication between the ports.

3. A disturbance-actuated valve comprising a housing, with a fuel inlet and outlet openings, a valve and stem therefor with a valve adjusting member on the stem and ports insaid adjusting member registering with the valve passages in the fuel inlet, a suspended member operating the stem, and means to determine the direction of disturbance to be effective through the suspended member to open and govern the extent of opening of the valve.

4. A, disturbance-actuated valve comprising a housing, fuel inlet and outlet ports therein, a port closure body therein having a stem, normally closing the inlet ports in the housing, and stem lifting means comprising a swinging member adjacent the valve stem and operable in either direction, and adjustable stop members for the swinging member to control the direction of initial i swinging action of the member fromnormal and the extent of. swinging thereof.
