RUBBER AIDS TO THE FOUNTAIN PEN. 



Having brought the fountain pen to a high degree of per- 

 fection, the makers of the Ideal Fountain Pen have placed on the 

 market a number of "little things" that very materially add to 

 the convenience and utility of the fountain pen in general and 

 Waterman's Ideal Fountain Pen in. particular. As these devices, 

 if not made wholly of rubber, are dependent on rubber for their 

 efficiency, we give them brief space in the columns of The India 

 Rubber Wurld.

tended to be used on fountain pens. Without injuring the finest 

 holder, it enables the tightest joint to be readily unscrewed. The 

 illustration explains the manner of its use.

point-section, as shown, its alternate compression.^ and release 

 draws and discharges water through pen and feed thoroughly 

 cleansing the passages. 



For filling a fountain pen the old style glass filler, still in use 

 and illustrated herewith, has been replaced by progressive pen 

 owners of the Ideal filler. 



It holds enough ink to fill any ordinary pen and the long tube 

 enables the pen to be filled from the bottom up, the formation of 

 air bubbles being thus prevented, a solid pen full of ink is secured 

 by withdrawing the filler as the ink is squeezed into the pen.

A ttUICK REPAIR FOR INNER TUBES. 



A SMOOTH and permanent splice, it is claimed, can be made in 

 an inner tube, with the aid of the device illustrated herewith, or.

 when it is impossible to make such a repair,' a new piece can be 

 spliced in with its aid and the tube made practically as good as 



new. • In performing the operation one end of the tube is inserted 

 in the male splicer and turned back 2]4 inches, as shown in Fig. 1. 

 1 he otlier end of the tube is then inserted in the female splicer, 

 turned back as shown and the parts washed with benzole or 

 gasoline to remove all foreign substance allowing time for its 

 evaporation. A coat of cement is then applied to the parts and 

 allowed to dry for ten iiiinutes, the female splicer is placed in a 

 vise and the male registered in the female as in Fig. 1.

Acid solution is poured into a small porcelain vessel and with 

 a clean brush is applied to the tube on the made splicer by 

 passing the hand from the bottom over the top and down the 

 other sides, moistening the entire surface; the male splicer is then 

 pushed into the female. 



The brass rollers on the male splicer automatically effect the 

 splice, which completes the operation as in Fig. 2. [M. & M.

A USEFUL POCKET SCREW DRIVEE. 



Equipped with four blades of different widths, contained in 

 a telescope handle and so retained, by a spring device that while 

 they can readily be removed for use, they will not rattle or fall 

 out if the cap is removed, each blade can be in- 

 stantly and firmly screwed in the handle for use. 

 The blades are 3/32, 5/32, 14 3nd % inches wide, 

 and the smaller sizes can be used to replace a 

 boring tool to make holes in wood to facilitate 

 driving the screws. The handle of the tool is 

 covered with hard rubber for insulation, so that 

 if used anywhere about electrical apparatus, there 

 is no possibility of the transmission of shock. 

 Being nicely ribbed, a firm grip on the handle is 

 assured. Extra blades, of any desired size, can be 

 obtained at small cost. For working among 

 electric wires, adjusting electrical apparatus, etc., 

 this is an ideal tool for the pocket or the kit.

THE CABINET TOKTABLE OVEN. 



A port.^ble oven, made of galvanized sheet steel 

 are designed to generate, with small consumption 

 of fuel, a high degree of heat, without radiating it 

 into the surrounding air, is illustrated tierewith. 

 The walls are all made double, the outer walls 

 being lined with a special make of air-cell asbestos, 

 which, with the intervening air space, makes an 

 excellent non-conductor of heat. 



The oven can be arraiiged for heating with 

 either artificial or natural gas, coke, coal or wood. 

 To ensure the even circulation of heat, the fire box 

 is separated from the baking chamber immediately 

 above it, by a double plate, having an air Space be- 

 tween it and the baknig space above; the back of 

 the baking chamber is divided from the hot-air 

 chamber in the back, which is a continuation of 

 the hot-air chamber at the bottom, by means of a single plate, in 

 which there are slats to provide for uniform distribution of the 

 heat.
