ROBERT D. WHALLEY, OF PROVIDENCE, RHODE ISLAND.
VULGANIZING-PRESS DETECTOR.
Application filed .Tune 25, 1919.
To all whom it may concern:
Be it known that I, ROBERT D. WVHALLEY,
a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Vulcanizinglress Detectors, of which the following is a specification.
This invention relates to certain new and useful improvements in vulcanizing press detectors, and the primary object thereof is to provide a detector which will make a positive record of the time or period during which the mold is under pressure.
The invention further aims to provide means of a novel character for carrying the object into effect, which means is of a simple character and of certainty in operation.
Further and other objects of the invention will be later set forth and manifested in the course of the following description.
In the drawings:
Figure 1, is a front elevation showing the invention applied to a vulcanizing press, parts being broken away and in section;
Fig. 2, is anenlarged section on line 2-2 of Fig. 1;.
Fig. 3, is a section on line 83 of Fig. 2;
Fig. 4, is a detail enlarged fragmentary view of one of the paper dials.
In proceeding in accordance with the present invention, a rod 1, is suitably se cured to the reciprocal bed 2 of the ordinary form of vulcanizing press, which lat ter are made with hollow beds and tops into which steam is fed so as to cure the rubber goods by the resultant heat. A
.well 3, is carried by the outer end of the rod 1, as depicted in Fig. 1.
To the upper part of the press is secured an ordinary form of time clock 4, the latter having a marking pen 5, that is removably secured to the arm 6, by a screw 7. The arm 6 is secured to a slide or head 8 and extends laterally therefrom through a slot 9 in the cover 10 of the casing 11 in which the slideis reciprocally mounted. V The slide rod 12 extends through one end of the casing and is pivotally connected, as at 13, to a link 14 which has a flexible section in the nature of a cord 15 passing over a pulley 16 and suspending a weight 17 within the well 8. This pulley is journaled in the outer end of a tubular arm or bracket 18 extending horizontally Specification of Letters Patent.

from the clock case. A coiled spring 19 encircles the slide rod 12 between the slide and the adjacent end of the casing for exerting its expansive force to move the slide when the force of the weight is otherwise counteracted. A set screw 20 is threaded through the opposite end of the casing and serves as a limit stop for determining the travel of the slide.
In operation, a mold carrying the article to bevulcanized. is placed in the press and the bed 2 elevated to subject the mold to pressure. This upward -movement of the bed 2 lifts the weight 17 and thereby releases the coiled spring 19 for shifting the slide in the casing, which shifting or sliding movement of the slide will carry the marking pen inwardly over the constantly moving dial 21 and cause a mark to be made thereon, thus indicating the period or instant at which the vulcanizing process began. Then the bed 2 is lowered the weight will pull the slide toward the opposite end of the casing against the action of the spring and again move the marking pen but in an outward direction, thus indicating the finish or completion of the vulcanization. The interval of time consumed may then be readily determined by a read ing of the marking, such as 22, on the dial.
The degree of movement of the marking pen may be controlled by the set screw 20 so that a single dial may be used many times by changing the path or extent of movement of the pen.
The construction is simple and sure of operation for recording the elapsed time for the different vulcanizations, whereby a permanent record may be kept and a check on the operator.
Having thus described my invention, what I claim as new and desire to secure by Let tors Patent is- 1. A vulcanizing press detector comprising a rotatable clock dial carried on the upper bed of the press, a tubular arm extending laterally from the case of the clock, a pulley journaled in the outer end of the arm, a weight cupfcarried by the lower bed of the press beneath the outer end of the arm, a casing fixed on the upper bed and formed with a slot, a slide operable in the casing, a laterally extending arm projecting from the slide through the casing slot, a marking pen connected to the second arm for being moved thereby across the face of the dial, a coiled spring interposed between the slide and one end of the casing, a slide rod extending through the said end of the casing, means extending from the slide rod over the pulley, a weight in the cup connected to said means, and a limit stop adjustable through the opposite end of the casing.
2. A detector for vulcanizing presses for recording the period throughout which the mold is under-pressure, comprising a spring actuated marking element, weight controlled means normally tensioning the spring, a rotatable clock dial over which the marking element is adapted to move, and means operable by a movable part of the press upon movement of the press bed to pressure-applying position i or raising the weight and thereby releasing the spring actuated element by allowing release of the tension of the spring.
3. A detector for vulcanizing presses for recording the period throughout which the mold is under pressure, comprising a marking element, a dial over which the marking element is adapted to move, means for moving the element in one direction of travel, and other means normally counteracted by the first means and releasable therefrom by a movable part of the press upon movement of the press bed to pressure-applying position for moving the element in a reverse direction.
4. In a detector for vulcanizing presses for recording the period throughout which the mold is under pressure, a marker, a clock dial over which the marker operates, means to tension the marker to move same radially of the dial, a weight connected to the marker to move same in the opposite direction against the tension of said means, and means borne by a movable part of the press to engage and lift the weight to relieve the tensioning means of the action of the weight upon movement of the press bed to pressure applying position. 5. A detector for vulcanizing presses for recording the period throughout which the n.old is under pressure, comprising a dial, a marking device movable thereover, means tending normally to move the device in one direction, other means for moving the device in the reverse direction and to hold it against the action of the first means, and means operable by the movable bed of the press upon movement of the press bed to pressure-applying position for rendering the second means inoperative upon upward movement of the bed and operative upon downward movement of the bed.
6. A detector for vulcanizing presses for recording the period throughout which the mold is under pressure, comprising an indicating device, means for moving the device upon one direction of travel of the movable bed of the press, other means for moving the device reversely upon movement of the bed in the opposite direction, and means for regulating the movement of the device, said last named means being adjustable so as to allow markings to be made at difi'erent points circumierentially of the dial.
7. In a detector for vulcanizing presses for recording the period throughout which the mold is under pressure, a marker, a clock dial over which the marker operates, means to tension the marker to move the same radially of the dial and inwardly thereof, other means to normally hold the marker outwardly of the dial, and means whereby upon upward movement of the movable bed of the press the last named means will be rendered inoperative and upon downward movement of the bed will be restored to operation.
