JOHN IB. RICKETTS, OF KANSAS CITY, MISSOURI.
vAULT-LIGHT.
Application filed January 16, 1915.
To all whom t may concern:
Be it known that I, JOHN B. RIoKE'r'rs, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Vault-Lights, of which the following is a specification.
My invention relates to improvements in vault or sidewalk lights, and one object of the invention is to provide the margins and lap joints of the metal frame with antileak joints, capable of normal contraction and expansion without detriment t0 the leak-proof qualities of said joints.
A further object is to provide a metal frame which may be manufactured at small cost and will not wear smooth from long service.
Other objects of the invention will hereinafter appear, and in order that said invention may be fully understood, reference will now be made to the accompanying drawing, in which:
Figure l is a broken plan view of the invention. Fig. 2 is a broken isometric view showing a lap joint employed in carrying out the invention. Fig. 3 is a broken longitudinal sectional view of the invention. Fig. 4L shows a modified form of joint.
In carrying out the invention, I employ a metal frame l, consisting, preferably, of inexpensive material, such as malleable iron which will not wear smooth from long use.
Said frame has intersecting transverse and longitudinal ribs 2, forming openings for the reception of the usual lenses 3, which rest upon shoulders 2a, of the ribs 2, where they are held by a suitable elastic cement 4, which allows for the difference in expansion and contraction between the metal frame l and the lenses 3.
The borders of the frame l are provided with slots 5, so that when said frame is laid upon the usual cement bed 6, and the slots 5 are filled with cement, said frame l becomes firmly anchored to its bed on the cement becoming set.
That partof the cement in the slots 5, is reinforced by short twisted rods 7 extending down into the bed 6.
In order to prevent moisture or water leaking through the joint between the'frame Copies of this patent may be obtained for ve cents each, by addressing the Washington, D. C.
Specification of Letters Patent.
Patented Feb. 22, 1916.
Serial No. 2,575.
l and the cement bed 6, the borders of said frame 1 are provided at their undersides with corrugations or serrations 8, into which the cement becomes embedded and acts as a series of dams in excluding the water or `moisture from said joint.
The lap joint between two panels of the frame l, is provided with serrations 9 and grooves l0, and a strip of sheet lead or other suitable packing ll, is inserted between said joint. The serrations 9 become embedded in the packing Il and constitute a series of dams that eifectually prevent leakage at said joint.
The usual T-bar l2 is placed beneath the lap joint to support the same.
In the modified form disclosed by Fig. 4, the lap joint is dispensed with between the panels of the frame la, and the adjacent margins of said panels are spaced apart to admit a rib 12a of a supporting bar 12b, which has a pair of oppositely-disposed anges 12C, to support the margins of the panels. The underside of the margins have serrations 9, which are embedded in packing strips lla, placed upon the flanges 12.
Having thus described my invention, what I claim and desire to secure by Letters Patent, is:
In combination with a pair of spaced adjoining panels having their bottoms provided with serrations in proximity to their adjacent sides, a bar having a vertical rib extending up into the space between the panels, oppositely disposed flanges on the bar having serrations receiving the panel serrations, soft packing strips between the serrations and abutting the rib, and vertical bolts passed through the flanges, packing strips and panels and located on opposite sides of the rib.
In testimony whereof I affix my signature, in the presence of tw witnesses.
JOHN B. RICKETTS.
