Hard-Rubber Spray. 



A SPRAY FOR ACIDS AND OTHER LIQUIDS. 



THE liard-rubber spraying attachment shown in the adjoining 

 cut operates with water or other liquid under pressure 

 to produce an extremely line spray. Owing to the resistance 

 of hard rubber to corrosive action, this sprayer is particularly 

 adapttd tor atomizing such acids as hydrofluoric, etc. The 

 nozzle consists of the inside and the cap 

 which fits directly on the pipe. The- 

 inside part gives the liquid the necessary 

 gyratory action to produce atomization 

 or spray. Clogging is reduced to a 

 minimum because the slots on the in- 

 side part are large compared with the 

 nozzle orifice. This nozzle can be 

 cleaned without removal from pipe. 

 The construction can be varied to suit 

 the requirements, and the nozzle works in any position. (Mon- 

 arch Manufacturing Works, Inc., 3129 Emery street, Phila- 

 delphia, Pennsylvania.) 



ANOTHER CAP COVER AND CHECKERBOARD. 



Although an armistice has been signed, it is probable that 



there will be otficers in uniform for some time to come, so 



that another 

 t\pe of rub- 

 berized cap 

 co\er may not 

 le amiss. As 

 the officer is 

 not allowed tu 

 carrv an um- 

 brella, such 

 cap covers are 

 an essential 

 part of his 

 equipment. 



The one 

 shown here is 

 made of high- 

 grade quality 



olive-drab rubberized material, silk-finished, light weight, and 



has an elastic inserted in the edbe to facilitate adjustment over 



the cap. This cover is also made in the regulation khaki color. 

 While the peace treaty^ is being prepared, the million boys 



"over there" will need something to do in spare moments and 



the familiar game of checkers in a new guise will find a wel- 

 come, as well 



as from other 



players on thi^ 



side of the 



water who will 



appreciate a 



rubberize d 



checker - board 



that can be 



rolled or folded 



into small space 



This particular 



board is made 



o f rubberized 



khaki material 



and is accom- 

 panied by 24 



wooden checkers of contrasting colors. (Felsenthal Bros. 



Co., 512-520 South Fifth avenue, Chicago, Illinois.)

A PATENTED STUD FOR TRACTOR WHEELS. 

 .\ new device intended to be secured to the rims of agri- 

 cultural tractor wheels so as to give them a grip on both soil 

 and road, is the rubber stud of which a cross-section and draw- 

 ing are shown herewith. Cylindrical 

 pieces of solid rubber are vulcanized 

 onto circular metal pieces having 

 projections in bolt form underneath, 

 thus making possible their applica- 

 tion by any blacksmith and also al- 

 lowing for replacement when worn. 

 The metal base to which the studs 

 are attached is adapted for attach- 

 ment to rims of different widths. (Dunlop Rubber Co., 14 Regent 

 street, London. United Kingdom patent \o. 118,149.) 



FOR HOME CANNERS. 



.\gainst the time when fruit shall be ripe again and the 



housewife preparing it for winter use, somebody has devised 



a new kind of jar-holder, which, while simple in construction, 



is at the same time efficient. It is made entirely of wood. On 



the base is fastened a 



w^ooden block with a 



curved inner face to 



conform to the shape of 



a fruit jar. Opposite 



this block, attached to a 



screw, is an adjustable 



curved jaw by which the 



jar is held. The jar-

COMBINED SUPPORT AND APPLICATOR. 



The object of the instrument illustrated in the adjoining draw- 

 two-fold — to provide a support for protruding piles and, at 



iiig 



the same time, an appli- 

 cator of medicament to 

 piles or hemorrhoids. 

 The instrument is made 

 of rubber, but when in- 

 tended for use as a sup- 

 port, is made of harder 

 or less pliable rubber at 

 the base ' and ball, the 

 neck being of more flex- 

 ible rubber. The cross- 

 sectional view shows the 

 device as an applicator 

 with a detachable medi- 

 cament container inserted

the recess at the bottom. The bot- 

 tom of the container is collapsible so that pressure on it causes 

 portions of the medicated charge to be expressed at predeter- 

 mined intervals. The containers are to be filled separately at 

 the factory and sealed, thus providing sanitary means of applica- 

 tion. The base of the instrument is so shaped as to prevent un- 

 intentional pressure on the base of the container. It is claimed 

 for the invention, which has recently been patented, that it can be 

 worn without discomfort or inconvenience. (John T. Landis, 

 Nashville, Tennessee.)

 process canning. ( Smalley, Kivlan & Onthank, Boston, Mass.)
