' FERDINEND LUDWIG CLAREN AND HERMANN STELZNER, OF Lil'BECK, GEBMANY, ASSIGNOBS TO THE FIRM F IDRKGER'WEBK, HEINB. & BEBNH. DEA GEE, OF
Li'rBEcK, GERMANY.
DIVEBS HELMET.
Specification of Letters Patent.
Patented J an. 8, 1918.
Application filed. October a, 1914. Serial mfssa'm.
To all whom it may concern:
Be it known that we, FERDINAND LUDWIG GLAREN and HERMANN STELZNER, subjects of the German Emperor, and both residing at Liibeck, Germany, have'invented'certain new and useful Improvements in Divers Helmets of which the following is a specificationh In divers dresses or apparatus it is frequently desirable to manufacture the helmet as well as other parts of the apparatus of a light material. Frequently the helmet is made integral withthe upper part of the dress and referably ofpliable water proof fabric, rub or or the like material or on the )ther hand the helmet is made of removable.
' ith helmets for the object explained above.
Preferably'a single removable weight is pplied to the top of the helmet for the urpose hereinafter described.
Fig. 1 is a front elevation of a divers ress, the helmet of which is constructed ac- )rding to the present invention.
Fig. 2 is aside view ofthe upper part B thedress, and Fig. 3 is a similar view of a modification. Fig. 4 shows a'diver in working position lrnished with another modification of the lvention. I
In the construction shown in Figs. 1 and the removable wei ht for the helmet a consts of a U-shaped oop b, which is so conructed, that the end portions 1) thereof st on the shoulders of the diver and both ve chest weight cand the back art of the vin apparatus d can be attac ed to the col e1- ortions by means of cords c, d spective y.
In the modification shown in Fig. 3, the weight takes the form of a crest 1', which owing to its'formation isvery pliable and can be easily removed.
In the modification shown in Fig. 4 the weight b 'disksha-ped. This modlfication has cert in advantages. It might seem natural to distribute the weight on the helmet, so that the center of avity lies in the center of buoyancy. owever it seems to be more advantageous to arran e the additional weight-on the very top of e helmet as is shown in Fig. 4, in which the diver is seen working in a bent or stoopin position. In this position the center 0 buoyancy may be considered to be at 1,while the chest weight is attached to the helmet at 2. If however the weights are so distributed that the center of gravity is also at 1, such a weight would have to be comparatively large. When however the weight is concentrated at the top of the helmet as shown in Fig. 4, in which the center of gravity will be at a considerable distancefrom the center of buoyancya reduction of the weight will be possible to a great extent.
When the helmet, instead of being made' of a ri d material is made of a pliable fabric or t e like, it is of advantage to make use of a metal ca on the top of which the additional weig t b is attached, and which protects the pliable helmet a inst injury.
Ifso desired the cap itself may be so 'constructed as to form the additional weightitself. Such a cap can be easily made removable and if desired can be perforated.
We claim: The combination of a divers helmet and a removable U-shaped'hoo adapted to rest on the shoulders of the and the back part of the diving apparatus attached to the shoulder portions of the h p y rnnnmm LUDWIG OLLREN.
