FLEXIBLE DOOR BUMPER. 



By the use of a simple invention, that of a single wire 

 in the proper form, the banging of doors and the niarr 

 walls becomes an impossibility. As 

 the illustration shows, one end of the 

 wire is threaded, forming a screw 

 for its attachment to the door, while 

 the other end, which is slightly tap- 

 ering, is finished with a rubber cap. 

 As there are no metal rivets or 

 screws in the rubber attached, it is 

 claimed that it will last for an un- 

 usually long time. Then, the fie.xibil- 

 ity of the spring relieves the rubber 

 somewhat, adding to its possibilities 

 of longevity. The mere thought of 

 the noiseless swinging back of doors 

 brings a sense of rest, and the real- 

 ity is sure to be a boon to people 

 who are "conscious of nerves," as 

 well as to those who deplore the dis- 

 figuring results on walls. These 

 bumpers are made in all the regular 

 hardware finishes from ebony black 

 to antique brass. [The Shelby Spring

RUBBERTEX— A WATERPROOF CLOTH 



The name "Rubberte.x" has been 

 applied to a new line of textile prod- 

 ucts, resulting from a water-proofing 

 process which involves no use of rub- 

 ber. Space is given to the subject in these pages because the 

 goods referred to are offered to the trade as a substitute for 

 rubber factory products, and they seem to have stood the test 

 of time satisfactorily. Cotton or other fabrics are used as the 

 basis for "Rubberte.x,'' being treated with a peculiar petroleum 

 product, in such way as to render the material waterproof, while 

 leaving it pliable. As will be inferred from this description, 

 "Rubbcrtex" is not injured by contact with oils. This material 

 has been used with success for machinery belting, for which pur- 

 pose it is not injured by outdoor exposure. In fact, a mill in 

 Wisconsin is mentioned at which "Rubbertex" belting has been 

 used for months under water. The same material, prepared 

 under a somewhat different process, is used for steam and cold 

 water packing. Other uses are roofing, carriage and wagon 

 tops, tarpaulins, horse blankets, fertilizer and cement bags, and 

 so on. An advantage referred tc in connection with "Rubbertex" 

 roofing is that no paint is used in laying it. The manufacture 

 is protected by United States patent No. 820,694, issued May 15, 

 1906, to Lon A. Bond. [Rubbertex Cloth and Paper Co., Logans-

SPENCER TURBINE CLEANER. 



This cleaner is a powerful air pump, without pistons or valves 

 or connected mechanism of any sort, and is operated by an elec- 

 tric motor or any other available power. The tools used in 

 cleaning are wide slotted and by the large volume of air drawn 

 through them all the necessary force is acquired to take up the 

 accumulation of dust in carpets, rugs, or upholstery, without 

 injury to the 

 textile. In sweep- 

 ing carpeted or 

 wood floors and 

 for various other 

 forms of cleaning 

 there is employed 

 in the Spencer 

 system a clean- 

 ing tool having 

 a slot 20 or 30 

 inches in length 

 and ^ of an 

 inch in width. 

 Using such large 

 orifices in i t s 

 tools it can take 

 up larger objects 

 and therefore 

 has a wide range 

 of utility as well 



as expeditious method. Its capacity is net limited to carpeted 

 buildings, but it can be used with an equal degree of efficiency 

 in the factory, printing office, and the like, and is as successful 

 in extracting the dust from the floor of a car as it is in remov- 

 ing it from its cushioned seats. The dirt and dust so extracted 

 is deposited in a capacious drawer in the machine which may be 

 emptied in a moment. In installing these cleaners they are put 

 in the basement, preferably with one or more pipe risers, pro- 

 vided with inlet-valve-hose connections to connect with all parts 

 of the building. But small space is required for their installation 

 and they do not require an experienced operator. The amount of 

 power necessary for operation is comparatively slight, and they 

 are designed for use from day to day in place of the ordinary 

 mop and broom, and not for an occasional housecleaning. [The

■MAPLEBAY" AUTOMOBILE TIRE COVER. 



A NEW tire cover made of waterproof leather that will not 

 shrink or harden is shown in the illustration herewith. The 

 tread fastens to tlu- iii;i of the wheel by means of fiat metal hooks, 



and it is claimed 

 to increase the life 

 of the tire four- 

 fold, these hooks 

 or clips serving to 

 prevent a large 

 percentage of the 

 punctures. The 

 attachment is 

 neatly made, the 

 clips going under 

 the edge of the 

 c 1 i n c h e r. This 

 cover is made to 

 fit any standard 

 tire on the market.
