New Goods and Specialties. 



A NOVEL FOUNTAIN-PEN FILLER. 

 CONTRIVAXXE to facilitate the tilling of 



intain pens 



/hich consists of a compres- 



th an extension, also of rub- 



which the pen is put, and a 



^-\ has recently been invented, 

 sible rubber bulb combined i 

 bcr. having a conical inouth-piece in 



base section intended to tit snugly 

 ver the top of an ink bottle as a 

 stopper. This stopper is fitted with 

 tube reaching into the ink, and 

 with air-vents at the top. When 

 the rubber bulb is compressed, the 

 drawn from the pen is forced 

 down the tube, through the ink, 

 in-Pen Filler. ^^p ^^^ ^^^ through the air-vents, 



while the ink is forced up into the pen. (Parke J. Flournoy, 

 SO V street, Washington, District of Columbia.) 



A NEW STYLE OF FOUNTAIN PEN. 

 Unlike the ordinary kinds of fountain pen, which must be 

 unscrewed in order to fill them, the one shown in the 

 accompanying illustration simply pulls apart in the center, re- 

 vealing within the presser bar for filling. The extent of the

The L^uGHLiN 



opening is regulated by shoulders on the inner tubing and the 

 holder which engage each other to prevent opening too far. 

 This pen is patented in the United States and Canada. ( Laugh- 

 lin Manufacturing Co., Detroit, Michigan.) 



RUBBER IN THE FLUOROSCOPE. 



The extent of the use of rubber in modern science is shown 

 in one of its luore recent adap- 

 tations in the lining of the tube- 

 box in fluoroscopes used by 

 Roentgen-ray diagnosticians. In 

 the accompanying illustration 

 the box is in the rear of the long 

 screen in front, only one end 

 being visible. The box itself is 

 made of hard-wood, lead- 

 coated outside and lined with 

 opaque rubber, thus insuring 

 protection from rays to both 

 operator and patient. The 

 fluoroscope is made in both 

 vertical and horizontal form, 

 the vertical one being shown 

 Jiere. (Wappler Electric Co., 

 Inc., 173 East 87th street. New 

 York City.) 



"AUTOGRAPHIC" RUBBERS. 



A recent patent provides for 

 the insertion of means for hold- 

 ing a name-plate inside the in- 

 step of a rubber overshoe, cov- 

 ered by a transparent pane of 

 celluloid or similar material. 

 This arrangement is provided 

 for when the rubber is manufactured, and any name-plate or card 

 may be inserted under the celluloid through an opening at one 

 end. (Alba C. Booth, Burlington, Vermont.) 



A NEW GAME BALL 



.A new ball to be used in pi 

 similar games, is covered with a 

 qualities of both leather and 

 rubber and containing some 

 rubber in its composition. 

 This covering is said to be 

 stronger than leather and as 

 resilient as rubber. It is not 

 affected by the weather and 

 may be used on wet ground 

 without injury to the ball, as 

 it is waterproof. It also re- 

 tains its shape under such 

 conditions and wears better 

 than leather. A rubber blad- 

 der of the usual type is used 

 inside. The ball is of regulation size and weight. ( Rawlings 

 Manufacturing Co., Si. Louis, Missouri.) 



"RAYBESTOS" MOLDED CLUTCH FACING. 



The newest kind of clutch facing is molded instead of woven. 

 It is said to be a great improve- 

 5jj mcnt and is being adopted as stand- 

 5'" ard equipment by manufacturers of 

 S5 automobiles and disk clutches. The 

 companj- that makes these facings 

 has discontinued the manufacture of the woven type except 

 to lill orders previously in hand for that style of facing. 

 Tlie molded facing is composed of asbestos fiber and rubber. 

 (The Raybestos Co., Bridgeport, Connecticut.) 



PUNCTURE-PROOF WHEEL. 



The wheel shown here practi- 

 cally accomplishes the feat of being 

 puncture and blow-out proof by 

 Its unusual construction. At the 

 tread is a tire of solid rubber vul- 

 canized to a steel rim. Beneath. 

 this rim are engaged two pneu- 

 matic tires between which a shock 

 absorber is positioned. This shock 

 absorber comes into use only in^ 

 case of an overload to the vehicle 

 or excessive wheel shock. (The 

 Eagle Puncture-Proof Tire & 

 West 42nd street, New York City. )

WHEEL WITH PNEUMATIC HUB. 

 .Another solution of the tire-puncture questio 

 in a wheel illustrated herewith. 

 This wheel has a solid rubber 

 tire at the tread, while the 

 pneumatic cushion is located 

 around the hub. A covering 

 plate which can be easily re- 

 moved gives access to the in- 

 flating valve and it is claimed 

 that inflation twice a month is 

 sufficient. The steel wheel may 

 be equipped with any standard 

 solid single, or dual tire equip- 

 ment, the pneumatic hub provid- 

 ing the desired resiliency. (The "Houston" Wheel. 

 Houston Pneumatic Puncture-Proof Wheel Co., Houston. Texas.)
