THE WORLD'S ADVANCE

A Drill Press 



A drill press which will be of interest to the 

 amateur mechanic who is handicapped by lack of 

 funds is the subject of a patent granted to an inven- 

 tor in Michigan. The press consists of an upright 

 standard in which a number of holes spaced equidis- 

 tantly are bored. Bolts passing through the holes into 

 a clamp hold the press in place on the workbench. 

 An arm projects at right angles from the top of the 

 standard and to it is attached a screw, at the lower 

 end of which is a clamp for holding the handle of the 

 drill. The drill is an ordinary brace-and-bit. 



Combination Clamp 



Two young men in Illinois have been granted a 

 patent upon a combination clamp for use about the 

 workshop or garage. It consists of a stout bar with 

 depressions cut regularly along one side and terminat- 

 ing at one end in a curved up foot. The remainder 

 of the clamp, which, with the exception of the screws, 

 is cast in one piece, moves up and down the main bar, 

 one projection fitting into the depressions. Two 

 distinct clamping operations, neither of which inter- 

 feres with the other, are possible. 



Toothbrush on Finger Tip 



Tooth brushes of every conceivable shape and de- 

 sign have been patented since the antiseptic properties 

 of that implement were first exploited by the dental 

 and medical professions some years ago. One of the 

 most unique ideas in this direction has just been 

 granted a patent. A man from Texas, where com- 

 pactness in the minor luxuries is still at par, is the 

 inventor. The new tooth brush resembles the glove 

 finger tip used in protecting injured fingers. 



Mixes Cakes and Frostings 



A pan for mixing cakes and frostings is the sub- 

 ject of a patent recently granted to a Wisconsin in- 

 ventor. The pan, except for its unusually long 

 handle, outwardly resembles the conventional house- 

 hold coffee mill. A knobbed handle projects from the 

 top and is braced by iron arms which go to the sides. 

 Within the pan, the handle is bent in a series of con- 

 volutions of a design best adapted for the purpose of 

 mixing frostings thoroughly. 



Crochet Thread Holder 



Now that the craze of knitting various articles of 

 usefulness for intrenched soldiers is at its height, 

 the social world should be interested in a patent 

 which has recently been granted to an inventor in 

 the District of Columbia for crocheting. The device, 

 which appears to be somewhat complicated to the 

 layman, consists of a base, spindle supporting uprights 

 and a bow-shaped guide. The bow-shaped guide has 

 a length equal to that of the bulk which moves along 

 the spindle, thereby permitting the thread as it un- 

 winds an unhampered movement. The bow-shaped 

 guide prevents the bulk from moving against the 

 spindle supports. 



Wire Puller 



A wire pulling machine which has advantages over 

 those now on the market has* just been patented. It 

 embodies a combined ratchet, a pull in one direction 

 locking the wire and spur in a sliding bar. A 

 handle engages another spur in a sliding bar. A 

 hook is provided on a bar to which the handle is 

 pivoted. The handle is a powerful lever. 



Turns Leaves of Music Portfolios 



Pianists appreciate the embarrassment which arises 

 when suddenly, in the midst of a difficult selection, a 

 draught of air causes the sheets of music to fly over 

 and the exasperated musician to lose his place. This 

 unpleasantness is eliminated in an ingenious little de- 

 vice, invented by a man in Indiana, which turns the 

 pages over as the pianist wills. Thin levers reach out 

 to the individual leaves of the music book, and when 

 the pianist desires to turn over a page, he or she 

 merely presses a pedal. Pressing another pedal, by 

 an arrangment of cogs, turns the leaves in the reverse 

 direction. 



Saw Holder 



A duplex clamp for holding a saw in place in the 

 top of a tool chest has been brought out by a Penn- 

 sylvania inventor. The handle of the saw is clamped 

 in place by a block and winged screw, while the op- 

 posite end is held by a spring snap. This holder 

 effectively prevents the saw teeth from coming in 

 contact with other tools and thereby suffering injury. 

 It also makes certain that the saw can be found, 

 when required, in its proper place.
