Specification ofjLetters-BatentNo, 5,478,79gjdated0ctober for the Sides of Vessels and for other Purposes, of which the following isa full, clear, and exact description, reference being. had to the annexed drawings of the same, making part of this specication, in which- Figure l is a view of the inner side of the apparatus applied to a detached portion of the side of a vessel.

Fig. 2 is a section taken vertically through the apparatus, the guard door and glassframe being opened for the purpose of ventilation. Fig. 3 is a transverse sectional view showing the manner of fastening the glass frame by means of a lever and inclined plane.

The same letters indicate the same parts in all the figures.

The glass lights in the sides and stern of a ship are usually mounted in frames which are secured to the casing of apertures for the admission of light and air into the hold, which frames open and shut von hinges in order that they may perform the double oilice of windows and ventilators. Heretofore it has been found exceedinglydiiiicult to make the joint between the hinged frame and the casing perfectly water-tight and cases are by no means uncommon where the leakage has been so considerable as to damage the cargo and even to endanger the safety of the vessel itself. To prevent the 'recurrence of such accidents as these is the object of my present invention which I accomplish by very simple but effectual means. which consist in providing a permanently elastic and durable seat around the casing of the aperture for the hinged glass frame to shut against; this elastic seat or cushion I form by making a groove in the casing which is creased on the sides, and then lling the same heaping full of strips of caoutchouc or gum elastic cut from a sheet or web of the prepared article; I then place a flatj ring of metal upon the gtun and clamp it down tight, which compresses it into all the creases and thoroughly fills every part of the groove; in this state I place the casing in an oven heated to three hundred degrees, more or less, of Fahrenheits thermometrical scale and bake the gum until all the moisture and uncombined :volatile matter is evaporated` and thestrips one solid: mass ;A the.A case-is then withdrawn rings are unclamped andthe gum` will be fou-nd tobe sosolidiand so firmly embedded 1n thel groove that. itcannot be removedl without considerable diicultyff. This proc-- ess I call baking-in the gum andv it is very much expedited by clam ing a number of the cases together and baking all of them at the same time.

degree impair the elasticity of the gum it eifectually destroys or removes all its stickiness, so that chips, weeds, and other obit as they do to the unbaked gum upon the: surface of which they accumulate to an eX- tent which prevent-s the frame from closing tight.

In the accompanying drawings A represents a portion of the plank or side of a vessel to which my improved glass light isapplied.

ture for admitting light and air into the h old, this casing is secured to the vessels lside by screws or otherwise; on the inner side of the casing a groove (a) is formed between two projecting concentric rims the sides of the grooves being furrowed creased or roughened for the purpose of retaining the gum (m) more firmly as before described.` On one yend ofthe casing a female boss projects in which a female screw is made to re ceive'the male screw (c) which yholds down and compresses the glass frame upon the gum On the other end Vofthe casing standards project to which the glass frame is secured by joint pins, which form the hinges on which it turns; the glass frame (d) is in the form of a flatring with a suitable groove on its inner edge to receive the glass, and having a flange or projecting rib (e).Y on its innerside concentric withthe aperture`- (o) in the casing and shutting upon the middle of the ring of baked gum -in the groove (fr) the riby (e) is compressed into the gum by turning down the thumb screw (c) so that Athe joint is perfectly water tight. v

more expeditious and equally secure and permanent method of fastening and compressing the glass frame upon the gum is to employ a lever (m Figs. 1 and 3) hingedl by fromr theA oveny and cooled after which the While this baking process does not in any Y B is the casing which surrounds the aper- `for shreds are agglutinated together and: form structons, have no tendency to adhere to one end to the casing, and having a notch on its side which projects over the edge of the glass frame and catches upon an inclined plane (n) on the front edge of the same, which inclined plane it depresses together with the frame as it moves along over it until it arrives at the top where it enters a curved depression and remains at rest;` thus,

the two fold operation of compressing the For the purpose of excluding the light andy also as a means of protecting the glass from violence I secure a hinged door (s) (Fig. 2)

von the outside of the casing this door is fastened open, or shut, by means of a bolt (r) which is slidden into catches or cavities (t t Fig. 2)

Having thus described my improved mounting for the glass lights of ships what I claim therein as new and desire to secure by Letters Patent, is-

Securing the caoutchouc by baking and compression in the creased groove of the casing, to form an elastic seat for the glass frame to be shut down and compressed upon, to make a watertight joint.
