A NEW RUBBEJtSTEEL VALVE. 



The V'oorhees Rubber Maiuifacturing Co., of Jersey Cily, 

 New Jersey, have put on tlie market a new pump valve which 

 has found a very ready sale. This valve, which they term 

 "Rub-Steel" is made by a combination of rubber and steel. 

 The construction consists of a plate of high-grade steel placed 

 in the center of the valve, with a specially tough and lasting 

 rubber composition on each side attached securely to the metal 

 Ijy the company's new "Elchemco" process, which deposits on 

 the steel plate a material in sympathy with ruijlicr and which 

 chemically unites the rubber and steel. 



The purpose of the steel plate, of course, is to give great 

 strength to the 

 valve so that 

 the highest 

 pressure cannot 

 warp, twist or 

 get it out of 

 shape, while the 

 rubber surfaces 

 a ff o r d the ———^ 



proper seating qualities. Ihis combination gives the valve a 

 rigidity of form which keeps the surface in its normal true 

 position. The inserted steel prevents the high pressure from 

 forcing the valve through the gratings, and the adhesion of 

 the rubber to the steel plate prevents the rubber surfaces from 

 breaking up and the displaced pieces from causing trouble. It 

 has the added advantage that it holds the valve in perfect shape, so 

 that when one side becomes worn, it may be reversed without 

 dressing. By reason of their rigidity, these valves can be 

 made thinner, and therefore secure a greater efficiency for the 

 pump, and they also permit of a softer valve being used for 

 hot water than those in common use. It is claimed that the 

 even distribution of pressure secured prevents "dishing" and 

 the consequent cutting of the valve. 



THE ■■AUTOMASSAGE" SHAVING BRUSH. 



The brush shown in the accompanying cut represents the latest 

 improvement in shaving brushes and combines ordinary bristles 

 for application of the lather and a massage 

 device for rubbin,g it in, both operations be- 

 • ing efifected at one time. The bristles are 

 ' "Centuryset" in rubber, and the brush is 

 made in two grades, fully guaranteed. The 

 massage device consists of a cluster of rub- 

 ber lingers vulcanized in the center of the 

 \ bristles of an ordinary size brush, and in 



y addition to the saving of time effected, it 



rv ^^^^\ gives an invigorating luassage with every 



I *j".-»^'i shave. The brushes are sterilized and pack- 



ed in individual sealed boxes, insuring the 

 consumer a sanitary article which has not 

 been "tried" by previous prospective cus- 

 tomers. It retails at popular prices. (The

CLINICAL THERMOMETER IN HARD RITBBER CASE. 



The accompanying illustration shows llie Harvard One-Minute 

 Clinical Thermometer in a case which is also a sterilizer. 

 This case is made of hard rubber, finely finished, and fitted 

 with a diaphragm which makes it possible to carry in the 

 case any desired sterilizing solution and to withdraw the ther- 

 mometer or to lay down the case without losing a drop of the 

 solution. As the thermometer is withdrawn the diaphragm 

 within the case automatically closes, preventing spilling or 



evaporation of the contents; and yet the case is so simple in 

 design that both the diaphragm and the ends of the case may 

 be remiiMcl lo iiermit nf cltaiising the inside of the case. The 



(iiR-miiunr chnical thermometer in the )lar\ar<l -.tcrili/er casi 

 should be a valuable aid in the sick room. [The Randall- Faichncy

NO MORE EXCUSE FOR GETTING COLD FEET. 



Here is a benefactor who has destroyed the gr^at enemy of 

 mankind — cold feet. He is Levet A. Long, of Dayton, Ohio. 

 And here is the description of his cold feet annihilator. 



It is an insole, made of three layers of material. The ac- 

 companying illustration shows a top view of the insole with a 

 part of the two upper layers cut away so as to give an idea of 

 the three. The top layer, Xo. 1 in the figure, is made of some 



pervious material, either wool or cotton. The bottom layer, 

 .\o. 3 in the figure, is of some impervious material, preferably 

 rubber. But the middle layer. No. 2 in the cut, is the one that 

 really does the work, which perhaps may best be described by 

 quoting from the patent specifications: "The upper layer, 1, 

 comes in contact with the sole of the foot. To create a sensation 

 of warmth a suitable chemical irritating medium is provided. 

 This layer is formed of Cayenne pepper or capsicum, and is 

 interposed between the upper and lower layers 1 and 3. The 

 capsicum is preferably mixed with wool and united by any suit- 

 able form of binder, such as an antiseptic adhesive. 

 When the insole is in use, the moisture from the feet 

 is sufficient to dissolve a portion of the active principle 

 of the chemical irritant which comes in contact with 

 the sole of the foot when the fabric 1 becomes moist- 

 ened. The effect of the capsicum will be to draw the 

 blood of the body to the feet, thereby producing a 

 sensation of warmth." 



What a boon t:i the great cnld feet family, which con- 

 stitutes ninety-five per cent, of the human race. When 

 this new invention is in general use — as must shortly 

 come about — the early greeting between friends will 

 no longer be "Good morning" ! Have you used Pear'> 

 soap?" but "Good morning! How is your Capsicum 

 Layer pulling?" 



A TRANSPARENT FOUNTAIN PEN. 



A new and unique merit has been added to the 

 Parker's "Lucky Curve" fountain pen, which has had 

 earlier mention in these columns. The barrel of the 

 pen is now made of Bakelite which has all the char- 

 acteristics of hard rubber with the added merit of 

 transparency. With this new device the quantity of 

 ink in the barrel is no longer determined by computa- 

 tions based on memory, weight and specific gravity 

 with or without a table of logarithms. The user holds 

 the Bakelite barrel up to the light and the literally 

 dark mystery is solved. Ease, quickness and certainty 

 of filling are also claimed for the pen. [Parker Pen
