WHISTLE.

i SPECIFICATION forming part of Letters Patent No. 550,240, dated November 26, 1895.

Application filed June 2l, 1894. Serial N0. 515,247. (N0 model.)

To @ZZ whom t may concern,.-

Be it known that I, FRANK M. ASHLEY, a citizen of the United States, residing at Hawthorne, county of Passaic, State of New J ersey, have invented certain new and useful Improvements in IVhistles, of which the following is a specification.

The object of my invention is to provide an improved steam-whistle wherein the bell proper is held at the top and the supports extend to the base outside of the bell.

The object of my invention is also to overcome the objection of the cracking of the bell, which so often occurs when the bell is made of cast metal, especially in the winter time. The metal as commonly cast gets very cold, and when steam of high temperature is suddenly admitted the belt is liable to and in fact often does crack, usually starting at its lower end. In order to overcome this, the bell is cast very heavy, thereby rendering it very hard' to blow and increasing its cost, or rings are fastened around its circumference j ust above its lower edge. This method is objectionable, as it is costly, makes it too heavy, and requires more steam to sound it properly. To overcome all of these objections, I select a tough metal, rolled or made into sheets, such as sheet copper or brass or steel, and, after forming said sheet into the form of a whistle-bell, su pport it above a cast-metal base by the arms, as shown. In this form they are very hard to crack', on account of the malleability of the metal, and are light in weight and can be sounded by a minimum amount of steam, and after making them for a period of eighteen months and subjecting them to the roughest usage I have not had a single bell cracked.

The invention also consists in the novel details of improvement that will be more fully hereinafter set forth, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure 1 is a partly sectional side elevation of mywhistle complete. Fig. 2 is a corresponding view of a slightly-modiiied form. Fig. 3 is a similar view, showing different means for sustaining the bell, and Fig. 4 is a sectional view of a modiflcation.- Fig. 5 is a sectional plan on the line 5 5, Fig. 1.

In the accompanying drawings, the num eral 1 indicates the bell proper, which is tubelike,y having its open end extending downwardly.

2 indicates the support or framework for the bell, which is composed of a circular upperv portion 3 and depending arms 4, that are connected at the bottom by a ring or band 5.

In Fig. 1 the bell 1 has a top portion 1, that projects through the ring 3, the bell being supported wholly at its upper portion. For this purpose I have shown the bell 1 provided with an annular enlargement G, that fits into a corresponding groove 7 in the ring 3 of the frame 2. The frame 2 is made of cast metal and the bell of sheet metal. The connection of the bell with said ring is made by passing the bell into the framework 2 so that its upper part will project beyond the ring 3, and the metal of the bell is then spun to cause it to flow outwardly into the recess v 7 and thus form the annular projection 6. The ring or band 5 i`s preferably severed at one part, as at S, and provided with outwardly-extending lugs 9, in which a thumbscrew 10 works, so as to expand or contract said ring or band.

11 is the base of the whistle, which may be arranged in any desired manner to connect with the steam supply, said base having a hollow inner portion 12 and outlets 13 to direct the steam against the bell 1. per outer portion of the base 11 is provided with screw-threads 14, that engage corresponding threads 15 on the inner part of the ring or band 5, whereby the frame 2 and bell 1 may be adjusted toward and from the base 11. In connecting the frame 2 to the base 11 the thumb screw 10 is loosened to allow the band 5 to expand, and when in position said screw is tightened, so as to firmly plant said band upon said base, whereby the frame 2 is securely held upon the base 11.

In Fig. 2 the upper end of the bell 1 is open and the top of the frame 2 is closed by a wall 16 to prevent the passage of steam, which acts similarly to the top 1 of the bell, the annular flange 6 in this case also being spun outwardly to iit in the recess 7 of the frame 2, as before explained.

In Fig. 3 the bell 1 is also supported at its top by the frame 2; but in this case the bell is held to the top 1G of said frame by a screw The up- ICO 17, that passes through the top l@ of the bell l and into the top 16 of the frame 2.

In Fig. 4 the bell l is open at both ends and the top of the frame 2 is closed, the bell being securely held to the frame 2 at its top by any suitable means, such as solder.

In all these cases it will be observed that the bell l is held at its top only, whereby its' lower portion is free to vibrate, and said bell is protected by the arms il of the frame 2, the escaping steam being allowed to pass out from between 'said arms.. rlhe steam is prevented from passing entirely through the belljeither by its top l or the top 16 of the frame 2. By

the above-described arrangement I am enabled to make a bell of sheet metal and to support it from 'its top in `a 'convenient man"- ner. The device is silnple in construction,

cheap to manufacture, not liable to get out y of order, and `effective in use.
