PROTECTOR FOR THE SAFETY DEVICES OF OIL-CONTAINERS.

Specification of Letters Patent.

Patented Sept. 17, 1912.

Application led May 28, 1912. Serial No. 700,266.

To al1-whom lit may concern.'

Be it known that I, ROBERT L. ZILLER, citizen of the United States, residing at Austin. in the county of Travis and State of Texas. have invented certain new and useful Improvements in Protectors for the Safety Devices of Oil-Containers, of which the following is a specification.

M v invention relates to safety appliances for containers holding inflammable explosive fluids, and particularly to that class of safety devices as disclosed in my Patent No. 1,011,395. granted on the 12th day of December, 1911. In my said patent, I disclosed a safety appliance includino a mass of resilient. refractory, independent filaments placed wit-hin the duct of an oil can, oil tank or other container for explosive inflammable fluids and preventing the passage of heat and flame to the interior of the tank, permitting, however, the passage of air into the tank and the passage of liquid out of the tank.

My present invention is designed as a means for preventing mischievous persons from picking out these filaments through the openings of the wire screens holding the lilaments in place within the duct, tube or other pasage wherein they are disposed, and also preventing the insertion of a sharp pointed implement into the duct or passaand into the mass of filaments which mig t tend to temporarily or permanently force the filaments to one side or otherwise injure the same.

A further object is to provide a device of the character referred to in the above paragraph which will not impede in any manner the passage of liquid either into or out of the contalner, nor impede the passage of air.

With these objects in view, my invention consists broadly speaking in the provision of a plurality of barriers spaced from each other and disposed in staggered relation above the filamentous packing, these barriers being so formed and arranged with relation to each other as to provide a more or le circuitons channel for liquid in passing into or out of the container, and entirely shielding and protecting the mass of resilient filaments.

My invention is illustrated in the drawings wherein:

Figure 1 is a fragmentary transverse section of a container for explosive lluids. the

protective device for the container being shown in section. Fig. 2 is a perspective detail view of the baille members removed from the safety tube. Fig. 3 is a like view to Fig. 1 but showing a modified form of the device. F ig. -l is a perspective view of the baiile members illustrated in section in Fig. 3. Fig. 5 is a diametrical sectional view of a modified form of the batile members. Fig. 6 is a perspective view thereof.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

eferring now particularly to Figs. l and '2, 2 designates a portion of a container of any suitable character shown herein as a tank for containing inflammable fluids, though the invention is intended to be applied to any form of container whatever.

Extending down into the container is a duct designated 3, this duct being prefer-A ably made of metal and of any desired length. The duct at its lower end is shown as provided with an inwardly projecting flange 4 forming a seatl for a wire screen 5 of relatively large mesh. Disposed upon the screen 5 is a mass of filamentous material 6 preferably the filamentous material described in my prior patent above referred to. Preferably disposed upon the top of this filamentous material is a wire screen 7 of relatively large mesh. These screens 5 and 7 are merely intended to hold the filamentous material in place. Disposed outward of or above the screen 7 or the mass of filamentous material 6, if the screen 7 is not used, is a baille member 8. In the form of the invention shown in Fig. 2, this baille is made of metal and consists of an annular ring having an external diameter approximately the same as the internal diameter of the duct 3 and having an inwardly turned annular flange 9. It will be seen that this baille member is hollow, and that when inserted in the manner shown in Fig. 1, the flange 9 is spaced from the wire netting 7. Itwiil also 'De seen that the opening 1G of the baille member 8 is located at the center. Disposed above or outwardly of the baille member 8 is the baille member 11 consisting of an annular ring having a diameter equal to the internal diameter of the duct 3 and having a centrally disposed solid portion 12. preferably of the same size or slightly larger than the opening 10, this central solid portion 12 boing connected to the annular wel?. 1i by radiating supporting webs 13.

will be seen that n. space 14 is left hetvfeen the annulm- Wsll of the member Il -oi' Huid to tion' throu h the mem ers 8 and 11 out of or info tie container. These bniles 8 and 1l it will he seen have barrier portions therefore which are placed in staggered relation to oooh other and th at no lm- )lement can bo forced or introduced mto the met l eyond these lm'lles 8 end l1 and Into -ongag'ement with cho filaments 6.

In Fig. 5 l show :mother form of my invention which is practically thosomo in operation as that shown in Fig.- l but in which tho bullies nre made of porcelain or like mebsrlal. ln this form, E. .is a baille corre sponding to the lmlllo 8. This hnfiie is nhnni los" in form ond has a. central opening l0a corrofmoncliog to the opening 10. The um der fors-o or' the baille, however, is slightly beveled or concaved es at 9 so that s, spese is left between tho body portion of this sin nuhu' baffle sind the Wire nettintg,I the onzin# lor baille 8 only touching the Wire netting at the periphery.

Disposed above and preferably resting upon the balile 8 is the baille ll This conn siste of a ring of material having :i control solid `'oz-tion doeii-*noted lo connected bn radii-rung webs 13, to the annular ring. These webs sro beveled upward so that the under face of the solid portion '.l2' L is higher t m the lor-ver edge 4of the peripheral ring forming the. margin of the member 11.*. ln this construction also it wiilbe noted that the bodies ore hollow so upon euch other, the main portions 'thereor will lao-spaced apart, and also that 'the solid portion 12e has staggered relation to the solid. portion 9 just as in the form previously described. This form of the device con be modo very cheaply by pressed poreehn which is hot-h strong and heet-resisting. ln 'both of these forms, the fest that the upper ostile does not rest upon' tho one beneath, not only provid@ n. space through which the liquidi/s able to flow orteil?I hut the arrangemsn; also rotects the peeking from hoeq n en there Ls {iome in the doot, as tho upper' member only touches the lower one at rim. and' the heating, of the opper diss 'convey only s. relatively ,nogligihlo or heet the ba'lle honesto it thst when restim non-explosive de' riesgoso In 3 and 4 l show another form of the invention. In these figures, 8 designates a duct such as previously described formed with' a flange 4. The mass of resilient {ilamonts 16 is held in place by means of the oppositely disposed screens l5. Resting" upon the uppermost or outermost screen is'hI hsfile member 17 comprising a marginal ring and bars 18 extending transversely across the ring :1t-spaced intervals.

Disposed upon the baffle member i7 is a. halile member 19 which is of precisely the seme constmction as the memher 18 and rests thereon ondisformed with transversely extending bars 20. There is this likeness however between the baille llmbrs4 17 and 19 that thshars 18 and 20 have e staggered relotion with regard to each other when the baffle members are the 'doot so that the ars of one member are disposed directly opposite the openings of the next adjacent member, thus preventin the insertion of an implement such esca mi?, wire oto. into'the duct and past the baille members or into engagement with the lsf ments. .lt will benoted that in this form of the imention, the baille members are substantiolly hollow, that is; the hars 18 and 20 are less in depth thanthe exterior e'ml ring-ond that this holds the A ors in spad relation lust as the solid portion 12 ropelly placed within eriph- 1n the form shown in Fig. 1 was held in V speced relation to the solid ortica 9. t

will he of course iinderstood ,i am not limited to the number illustrated in the drawings. It will also he seen that in Fig. l the outlet spaces for the liquid between the bars of one baille member i's the seme in ores as the aree of the spaces he# tween the bars' in the other baille member. Bry reason of the fact that I uso o, plurality or baille members, it is possible to combine at I may use orly number of those baille platos and. that various forms of bale members in any ou duct, or to provide :my desired bomber of these bale member Further it will be seen thatl these bale members ere very easily inserted and removed when desired, and that they form a thorough protection to the mass f resiient filaments m the interior oi the not.

It is to he understood that the' separate blo members might he connected to each other insmd of being separato :md independent, and also that these belli@ members ater being put in place :night he soldered or otherwise attached to the duct so als to prevent any removal of the baffle or any shifting of the parts. what elemi is:
