SPECIFICATION forming part of Letters Patent No. 680,874, dated August 20, 1901.
Application filed November 18, 1899. Renewed June 17,1901. Serial No. 64,933. (No model.)
To ctZZ whom it may concern:
Be it known that I, LLEWELLYN D. L0- THROP, a citizen of the United States, residing at Gloucester, in the county of Essex and State of Massachusetts, have invented an Improvement in Fog-Horns, of which the following is a specification.
The object of my invention is to provide a fog-horn of that class known as mechanical and adapted to be used on any sailing vessel, as heretofore employed in foggy weather for safety.
By means of my presentinvention I am able to construct a very powerful-toned fog-horn in a small compact case with allits parts very strong, light, and durable and comparatively easy to operate; and it consists in the construction, combination, and arrangement of the various parts, as hereinafter more fully described, and specifically set forth in the claims.
To the drawings hereto annexed, which form a part of this specification, reference is made.
Figure 1 represents a front elevation of the box or case, showing the horn on the right hand side of the box below the operating-lever. Fig. 2 represents a vertical elevation of the reverse side of the box with the back removed, showing the interior construction and arrangement of the opposite bellows with the exhaust and expansion tank and the connected mechanism for operating the fog-horn. Fig. 3 represents a horizontal sectional plan showing the opposite valves of the bottom block of the exhaust-tank and air-pipes connected therewith. Fig. 4 represents a horizontal section through the tank-block, showing the air-tubes screwed into the air-holes bored into the opposite ends of the exhausttank block. Fig. 5 represents a side elevation showing a portion of the exhaust-tank block with the bellows-leather secured within a groove formed in the block by means of a strip of perforated metal secured with nails, also showing the air-tube to connect the exhaust-tank with the fog-horn, having a flexible portion connected therewith. Fig. 6 rep resents a vertical section through a portion of the exhaust-tank block, showing a groove and metal strip for securing the lower edge of the flexible bellows-leather to the exhaust tank block to form a strong air-tight joint, and drawn on an enlarged scale. Fig. 7 represents a side elevation showing the horizontal rock-shaft and vertical actuating-lever and jointed vertical operating hand-lever removed from the box and drawn upon an en- A represents an oblong rectangular box having the fog-horn B secured in horizontal position on the right-hand side of the box below the operating hand-lever C, as shown in Fig. 1. This operating hand-lever C is adapted to be forced backward and forward within the slot or opening formed between the parallel horizontal guidebars D D (Shown in Figs. 1 and 8.) This operating hand-lever is secured at its lower end by casting in one continuous piece the horizontal rock-shaft E, vertically-operating bellows-bar F, hand-lever O, and cross-head G, as shown in Fig. 7.
The operating hand-lever O has a handle H pivoted to the upper end thereof and adapted to be folded down upon the top of the box A, as shown in Fig. 2, and is provided with a stop I at the joint when turned up. The stop is shown in Fig. 7. The said horizontal rock-shaft E extends outward through the front of the box A, which is provided with a flanged bearing H, formed of two similar interlocking pieces forming a short horizontal socket J, which fits upon the outward portion of the rock-shaft E and prevents its horizontal movement by means of the rib K, which is received within the groove L, formed in the inward end of the short socket J of the bearing H, when forced into the hole in the front of the box A to receive it and is secured in position therein by the vertical flanges H, secured to the front of the box A. Now in order to place the said rock-shaft E,
with the vertical hand-lever 0, made in a single piece of casting with the bellows-bar F, having cross-head G, in position in the bearings for the said rock-shaft it is necessary to form the opening in the front of the box A large enough to receive the two pieces of the flanged bearing H, then pass the lever portion 0 outward through the opening from the inside of the box, then insert the lower half of the flanged bearing H, then turn the lever portion 0 to a downward position therein, and then insert the upper piece of the flanged bearing into position. The extreme inward end portion N of the rock-shaft E fits within a journal-bearing O, secured upon a shelf P, which is secured to the front and back of the said box inside, as shown in Fig. 2. Now the handle I-I may be riveted to the end of portion 0 of the hand-lever, which is provided with a stop I, so as to form a folding op erating hand-lever, as shown in Figs. 1 and 2 and more fully in Fig. 7.
The portion 0 of the hand-lever is forced backward and forward between the horizontal guide-bars D and D The parallel guidebar D is secured at each end to the front of the box A by screws and holds the inner bar D in parallel position therewith by means of suitable end grooves formed in the opposite end bearings of the guide-bar D, as shown in Fig. 8.
Now I secure permanently in position within the box at opposite ends a vertical bellows S. To-thc inner faces near their upper ends is secured a projecting ear T, to which is pivoted one end of the horizontal actuating and reciprocating bars U, the opposite ends of which are loosely fitted upon the cross-head G of the vertical bar F, so as to be moved freely therewith. These bellows S are constructed with very thick back blocks V and have the wind or air passages bored into the lower ends thereof and the upper ends of the connecting air-pipes R screwed therein, and
their opposite lower right-angled end portions are likewise screwed into the thick bottom block X of the exhaust-tank bellows Y, as shown in Fig. 4:. The exhaust-tank bellows Y is provided on its top with two spiral springs Z, the upward ends of which have a bearing against the under side of the shelf P,as shown in Fig. 2. The exhaust-tank bottom block X is provided on its upper surface near each end with an air-inlet valve B held closed by a metal or suitable flat spring 0 whereby the wind or air forced through the said valves is forcibly expelled from the exhausttank bellows Y by means of the said spiral springsZ, which are compressed by the pressure of the air in the bellows Y, which is thereby forced through the central hole E into the air-passage F and connecting airtube H leading to the fog-horn B, secured in a horizontal position on the front right hand side of the box A beneath the operating hand-lever 0 H as shown in Fig. 1. Now in order to permit the fog-horn coupling to be screwed into the elbow L on the air-tube H when the same is not in exact line or position I provide the said air-tube H with a vertical flexible section P as shown in Fig. 5, which permits the connections to be screwed together when brought into line. Now in order to secure the bellows-leathers R to the front and back blocks of the said bellows and top and bottom blocks of the exhausttank I provide the edges of the same on all sides with a square or rectangular groove S extending continuously around the blocks and parallel to the opposite sides of the same. Then I provide a strip of sheet metal T a little narrower than the width of the groove S between its opposite parallel sides, then place the edge portions of the leathers R over the said grooves, and then drive said metal strips T and the leather R down into the groove S and secure the strips T with nails, whereby very strong, durable, and air tight connections are cheaply constructed,- as shown in Figs. 2, 5, and 6.
It will be seen that by securing a vertical bellows within the box at each end thereof and the operating mechanism midway between the same permits the upper ends of the bellows to be expanded alternately by each movement of the hand-lever, whereby very rapid action of the bellows is effected, and by placing the exhaust-tank at the bottom of the box between the smaller lower ends of the bellows produces a very compact economical arrangement of those essential parts whereby the size of the box is very essentially dimin= ished, as shown in Figs. 1 and 2. This com-' pact mechanism I consider of importance.
1 represents a metallic bellows-valve having a short tube 2, provided with an inclined seat- 3 and a hinged lid 4:, protected by an airguard 5, whereby the force of the wind within the bellows is deflected, so as to prevent it opening the said lid. It will be seen and understood that whenthe diameter of the largest portion of the handle H is no greater than the exterior diameter of said socket J of the flanged bearing H then the handle H may be riveted or otherwise secured to the end of the lever portion 0 previous to inserting the same into the opening formed through the front of the box A to receive the said flanged bearing H J, as above described. It will be understood that the top or cover of the box A is not secured in position thereon until after all the mechanical parts of the fog-horn signaling apparatus have been permanently affixed in their places within the box, as shown and described. The top of the box may have a carrying-handle or other means of hand transportation secured thereto, if desired.
Having thus described my invention, I claim 1. In a fog-horn signaling apparatus, an oblong rectangular box having secured to the interior thereof a vertical bellows at each end and a horizontal exhaust-tank at the bottom having an air-tube to the fog-horn on the outside of the box below the operating hand-lever, the said air-tube having a flexible section, whereby the screw-threaded connections with the fog-horn may be brought into true line in the act of coupling the same, substantially as shown and described.
2. A fog-horn signaling apparatus consisting of an oblong box having a vertical bellows secured to each end thereof and a horizontal exhaust-tank secured centrally to the bottom thereof and air-pipes connecting the bellows, exhaust-tank and fog-horn, and a folding hand-lever, a rock-shaft and connected actuating devices arranged between the bellows above the exhaust-tank, as shown and described.
3. In a fog-horn signal, the bellows provided with front and back blocks having rectangular grooves formed around their edges and the leathers of the bellows secured against the opposite sides of the said grooves by rectangnlar strips of metal forced into said grooves, whereby two parallel joints are formed between the leathers and blocks, as shown and described.
4. In a fog-horn signaling apparatus, the bellows provided with thick back blocks having the air-passages formed in the said blocks and the air-tubes connecting the same provided at each end with external screw-threads, whereby the metal screw-threads will serve to cut corresponding screw-threads within said air-passages in coupling the same together, and the air-tube leading to the foghorn provided with a flexible section whereby the screw-thread connection of the fog-horn may be brought into line to couple the same substantially as described.
