extinguishers and other articles which are HARRY n. TUNNE-Ln'or NEW YORK, N. Y.

HOLDER nonV FIRE-EXTINGUIsHnns AND OTHER ARTICLES.

1o all whom t may concern.'

Be it known that I, HARRY E. TUNNELL, a citizen of the United States, and a resident ofthe borough of'Manhattan, city, county, and State of New York, have invented certain new anduseful Improvements` in Holders for Fire-Extinguishers and other Articles, of which the following is a specification.

My invention relates to holders for ire to be used only on special occasions and which it is desirable to protect against unauthorized handling until a need for their use arises. The invention/` disclosed herein provides a holder which will make it impossible -for the lire extinguisher or other device to be taken out without detection, and which preferably will expose the said device to view even when safely contained in Aits intact holder, it being necessary to break a portion of the holder in order-to enable-the re extinguisher or other article to be removed therefrom. Y j n A preferred and satisfactory. embodiment of my invention is represented in the accompanyingidrawings, in which Figure 1 is a vertical section of the device on line 1-1 of Fig. 3 'F ig. 2 is a partial vert-ical section on line 2-2 of Fig. 3,; Fig. 3' is a horizontal as Fig. 1, illustrating the manner of assembling the holder. A

The holder `shown in the drawings comfr prises three main parts,`v'iz: axed supporti havingA a ing member, a frangible covertherefor, and an elastic member for connecting said supporting member with said cover. f

The supporting member is cup-shaped,

'cylindrical surrounding or uprightshell 10 and a horizontal wall or ledge 11 extending inwardlyfrom the bottom of the shell 10 to form a support for 'the'fireextinguisher or other article F. I preferan Y vapertured bottom, .or a bottom ledge, as shown (although this is not essential), inasmuch as this exposes to viewv from below, the bottom ofthe lire-extinguisher orV other article, enabling the inspector or the intending user to ascertain the type of apparatus contained in the=holder.A The supporting member is, made to be secured to a wall A or the like, as by means of screws B passing through suitable holes in brackets 12, 12

formed integral with said supporting meinbei'. In the particular construction shown, the brackets 12, 12, as will be seen best in Figs. 1 and 8, are made 'by cutting appropriate circumferential and upright slits in the shell 10 and bending the portions thus obtained, into the shape Q f brackets, Fig. '1 showing clearly that the upright (scalloped) edges of these brackets are counterparts, indicating' that they were produced by the f saine slit. At itsupper end, the supporting member has a circular opening 13, and at a short distance below the same, an annular internal groove 14 of greater' diameter than said opening, and still farther down, an annular .ledge or surface l5, of smaller inner diameter than the opening 13, so as to form a support in the path of the cover when the latter is introduced through said opening. Y,

The cover16 `is made of glass or other suitable frangible `material, preferably transparent so that the upperxpart'of the fire-extinguisher or other article F will Vbe visible therethrough. vThis cover is shown, dome-shaped, with its lower edge portion 16 adapted to become seated on the support 15. 'Above the edge 16, the cover is provided with an external annular projection oil bead 16" the outer diameter of which is slightly smaller than the diameter of the opening13, so that the cover may be readily introduced into the upper portion of the supporting memberv and made to rest on the support 15.

To hold the cover 16 inthe position illustrated, I provide a split locking or connect-` ing ring 17, made of spring steel or other elastic material, and having a tendency to expand to the diameter shown in Figs. 1, 2, and 8, and indicated by dotted lines in Fig. Preferablythe ends of the ring 17 are or tapered in such a manner that while their outer' circumference will remain unaltered, as indicated at 17 in Fig. 3; this enables the ring to be contracted more readily .and provides an additional safeguard t against tampering, as explained hereinafter. T hediameter of the openinghl should be slightly greater than the dimension ob- Y tained by adding twicethe thickness of the ring 17 to thediameter of the upper or body portion of the cover 16. -Also, the greatest external diameter of the bead 16 should be Y Vcylindrical upper or greater thesmallest internal diameter of the ring 17 when the latter' is in its eX- panded condition.

To assemble the holder, after the fire-ex- A tinguisher or other article has been placed on the support l11, the cover 16 is rested on the support 15, and the ring 17, in its ex pande'd condition, is slipped down over the cover 16. In its normal expanded condition, the ring 17 cannot enter the opening 13 (see dotted lines in Fig. 4:), but. by contracting the ring forcibly, it can be Vbrought into said opening, as illustrated by. i'ull lines in Fig. 4. By then pressingthe Yring 17 down,

it willfbe carried into registry `with the groove 14:, and since theY ring tends to expand, it will snap intosaid groove, thus assuming the locking position illustrated by Figs. 1, 2, and 3. In this position, the ring Y 17 will prevent removal oi' the cover 16 from since any upward the' supporting member,

force the ring 17 pull on the cover will only more firmly into thel locking recess or groove 14 by a we dging action.

VThe only way the Y other articles contained :in the holder can be removedfis to. break the coverf16.` As long as the cover is whole, this shows that the article has not been taken out sinceV such cover was placed in position. My invention provides an effective safeguard against yunauthorized use of the fire-extinguisher or.

other article,

in that it is impossible to take the apparatus out of its holder withQut detection, thefact that the cover is broken being presumptive evidence that the apparatus has been tampered with, unless it is known Ythat iti was used in a legitimate way.

My inventionalso aifords increased pro-` tection against theft of the lire-extinguisher or other article, inasmuch as the thief would have to break the kcover 16, and the resulting noise would attract the attention of any person within hearing. Y j

It will 4be obvious from Fig. 3, that it would be very difficult and, in

safety against tampering of this character should bel desirable, the annular space above thering 17, between the cover 16 and the uppermost portion of the supporting member, might be filled with cement or other suitable material, after lthe ring has been .placed Vin the position shown in Figs. 1, and l Various modifications may be made without departing from vthe nature of my invention as set y)forth in the appended claims.

I claim as my invention: j .j

1. A holder provided with a supportffor an article,

body portion of the` hre-extinguisher or Y fact, next to impos sible to pry the connecting ring 17 out ot the recess 14 so as to release theycover 16V witho'ut injuring it; however, if additional with an additional support, and with an annular recess adjacent to the lastiseosee i named-support, a'cover adapted to'irest on said additionalI support and provided with an external bead, and an elastic connecting ring adapted 4to'be seated in said recess and to engage said bead to lockthe cover to the portion having said recess.l

Y2. A holder provided wtih a support. for

" an article, with an additional support, Vand with an internal recess adjacent to the lastnamed support, a cover` adapted to rest on said additional supportV and provided withA an` external projection, and an elasticY connecting member adapted to be seated -insaid recess-and to ,engage said projection tolock the cover to the portion having said recess.

3. A holder provided withasupport for an article, with an additional support, with an annular recess adjacent to the last-named support, and with a portion located above said recess and surroundingan opening. a

vcover having an*v externally-beaded lower portion oi' smaller diameter than saidV opening, and adaptedk to become seated on said additional support, and an elastic ring, tending to expand,which in its normal eX- Ypanded condition is of greater-diameterthan saidA openingsaid;ring being adapted to iit into said recess and to engage the beadot' the cover, to lock V-thefcover to the portion having sad recess. j; Y

L1. A hol ler comprising a carrying mem@ ber havinga support for an article, another;A

support, an annular recess adjacent'to the lastnamed support, and an opening at the top, av lcover adapted to .rest on the secondnamed support andprovided with an'jeXternal projection which isfbelow the: level oi?V said opening when/,the cover. rest-son said,

support, ,Y and an elastic 'connecting ring adapted to be vseated inV said supporting member and-also to t againstV the external projectionof the cover, the outside diameter ofsaid-ring, when contracted e into contact with the bodyv of the cover, beingY less than the diameter of said top openi a way that their oblique surfaces will diverge inwardly.

In `testimony whereofV I have signed this specification. a n v f. A
