FREDERICK B. WAIBEL, OF NEWARK, NEW JERSEY.
DIP-TANK WITH AUTOMATIC COVER.
To all whom t may concern.'
Be it known that I, FREDERICK B. WAIBEL, a citizen of the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Dip- Tanks with Automatic Covers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make, construct, and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, forming a part of this specification.
The present invention relates to an improved automatic apparatus by which fires in, or which threaten the dip tank so extensively employed in factories, may be prevented from spreading, or completely extinguished, thereby saving the contents of the tank and preventing dangerous explosions.
The object of this invention is to provide an automatic apparatus which comprises a suitable stand, preferably made from angle- -iron, which supports the tank containing the varnishes, lacquers, and the like, said stand being provided with a cover held in open or locked position by holding means which are secured to the sides of said stand, said means being connected in any wellknown manner, preferably by a cable or wire provided with a series of fusible links which when the temperature of the room is abnormally increased, melts, thereby permitting the holding means secured to the sides of the stand which hold the covers in open or locked position to operate and release said covers, thereby closing the tank and preventing the access of air or fire thereto. f
A preferred construction of a dip tank with automatic covers embodying my invention is shown in the accompanying drawings, in which* Figure l represents a side elevation of a dip tank embodying my invention. Fig. 2 represents a plan view of the same. Fig. 3 represents an end elevation of the same, ine spring-actuated covers being shown closed, but the cover holding means being shown in operative position holding the covcrs shown in dotted lines in open and locked position. Fig. 4 represents a similar view showing the holdingpmeans in their inoperative position after the covers have been Specication o! Letters Patent.
Application led October 18, 1911.
Patented Mar. 19, 1912.
Serial No. 655,446.
6 represents a similar view of a modified form of a cover holding lever.
Similar letters of reference refer to like arts throughout the specification and rawings.
The tank a shown in the drawings is of the ordinary type, commonly used in factories and known as a dip tank, supported on a suitable stand b, preferably made from angle iron. The covers o, c are of ordinary construction, preferably made from sheet metal, hinged at d, d, so as to cover the entire top of the tank a when closed.
The automatic closing of the covers c, c may be effected by any suitable means, such as spiral springs e, c tending constantly to close the covers.
The covers c, c are held open against this tendency of the springs by the catches s, s, pivotally attached to the outer ends of the levers f, f, said levers being pivotally attached to the end frames g, g of the supporting stand at h, h. These catches s, 's are maintained in a downward position to hold the covers open by means of a flat spring z', one end of which is secured in a slot e" in the lever f and the other end of which bears against the upper and outer portion of the catch a close to that point where the catch is provided with a receiving or cut-out portion y', which engages with the end of the cover k.
Two sets of cover holding means are employed to hold the covers in open and locked position, one set on each end of the tank supporting stand. These cover-holding means consist of the levers f, f, which as previously stated, are pivotally attached to the end frames g of the tank stand. The inner ends of the levers f are connected by means of a stud l secured to one lever which passes through a slot m formed in the other lever. These levers or cover-holding means are held in their operative position as shown in Fig. 3 of the drawings, by a chain n, the ends of which are fastened to the apertured ears n of the levers and which then passes over the pulleys o which are conveniently mounted in uprights y of the stand b.
The automatic releasing of the cover holdingr means or levers muy he effected by any suitable means, such as a spiral spring q, tending constantly to pull the cover-closing means down as Shown in Fig. 4 of the drawings, one end of the spiral spring g' being fastened to the stud Z of the lever f, the other being fastened in any convenient manner to the cross-piece Q of the stand In order to render the operation of the cover-releasing means as sensitive and prompt as possible, the chain n is provided with a series of fusible links r of any com mercial form, which while sufficiently strong at ordinary temperatures to perform their function, will, when the temperature is abnormally increased, as in the case of fire, melt, thereby causing the levers secured to the sides of the stand which hold the covers in open or locked position to operate and release said covers, thereby entirely closing the tank and preventing access of air or tire thereto.
In Fig. G of the drawings, have shown a simple form of a lever t, forming one of the levers which constitute the cover-holding means, in which I have dispensed with the catch s and spring z'. This lever t is ivotally attached to the end fra-mes g in su stantially the same manner as the lever f, and is also provided with a receiving or cut-out portion u, designed to engage with the end of the cover t'. The lever shown in the drawings is also provided with a stud Z, designed to pass through a slot formed in the other lever.
Experience has demonstrated that the ore ganization above described is a highly ei-l cient one, and While the device described is the preferred embodiment of my present invention, l do not care to restrict myself to the exact details of construction, combination, and arrangement herein set forth, it being obvious that minor variations thereof not involving the exercise of invention may be made by any skilled mechanic, and such departures from what is herein described and claimed not involving invention, l consider as Within the scope and terms of my claims.
I claim:
1. An apparatus of the class described, comprising a supportingv stand for the tank, sprng-actuated covers secured to said stand,
i'liipies of this patent may be obtained for :tive cents each, by addressing the Commissionerof atentsn holding means secured to the stand for holding said covers in open and locked position, means for releasing said holding means interposed between the stand and said holding means and a fusible connection between said holding means rendered inoperative by heat to release the cover and close the tank.
2. An apparatus ofI the class described, comprising a supporting stand for the tank, spring-actuated covers secured to the stand, la pair of levers secured to the ends of the stand pivotally connected and provided With means for holding said covers in open and locked position, uprights fastened to the end of the stand in which are secured pulleys, and a chain provided with fusible links passing over said pulleys, the ends of said chain being secured to said levers, the fusible links being rendered inoperative by heat to release the covers and close the tanks.
3. An apparatus of the class described, comprising a supporting stand for the tank, spring-actuated covers secured to the sides of the stand, holding means secured to the ends of the stand provided with pivotally arranged lspring-pressed catches for holding said covers in open and locked position, a spring secured to the stand and to said holding means and a fusible connection between said holding means rendered inoperative by heat to release the cover and close the tank.
4. An apparatus of the class described, comprising a supporting stand for the tank, spring-actuated covers secured to said stand, holding means secured to the stand for holding said covers in open and locked positoin, a spring, one end of which is secured to said holding means and the other end of which is secured to the stand and a fusible connection between said holding means rendered inoperative by heat to release the cover and close the tank.
