Floor-Scrubbing Machine. It is no trivial task to scrub the floor of a large hall or the deck of a vessel with hand scrubbing brushes, aside from the exhausting effects of tn3 physical effort; and it would be a commendable act to provide the people peo-ple who are compelled to do this work with the recently patented floor-scrubbing machine shown in the accom- ( 1 - - leading down to the forward axle. Ai the lower end of the rod in a gear wheel which meshes In a. similar wheel rigidly f.xed on the carriage wheel. Instead of being attached di rectly to the rod the upper gear wheel is carried by a sliding sleeve, controlled con-trolled by a lever within easy reach from the wagon seat, by means of which the apparatus is thrown in and out of gear at will. The universal joint at the upper end of the rod permits per-mits the dvice to be brought into use with the axle in any position, and a backward movement of the horse will have no effect upon the reins, since the ratchet wheel prevents rotation of the spindle in that direction.

In the accompanying illustration is shown a novel idea for adjusting striking strik-ing bags, the object being to afford a means of vertical change in the po sition of the bag relative to the con tact ring beneath which the bag de pends, without causing the bag tc overreach the edge of th? ring when swung in any position. Ordinarily the cord which supports the hag has to be adjusted at the desired height by varying the length of the cord. By the time the knots are tightened the bag is seldom in the right place, and it is considerable trouble to change the position of the bag to fit persons of different heights. A glance at the picture will show that in this invention no change in the cord is necessary after it has once been fastened and passed through the vertical tube for attachment to the bag. The ring surrounding the tube is secured to the fixed wall bracket and a knot is provided for tying the end of the cord. The tube containing the cord is clamped in the end of the bracket by a thumbscrew. As soon as the tube is lowered the cord is shortened at the upper end and lengthened at the bottom to correspond corre-spond with the distance between the end of the tube and the edge of the contact bag, and when the tube is lifted the cord is shortened correspondingly. corre-spondingly. Consequently, no matter what the height of the bag may be, it never overlaps the edge of the ring, but always strikes in the right place. A3 a turn of the screw allows the tube For Use in Large Halis and on Ships. panying drawing. As there is no necessity ne-cessity for the operator to maintain a stooping position many a backache would be saved, not to mention the fulfillment of the practical business man's test of the value of an innovation innova-tion that of saving time. The machine ma-chine as shown comprises a large rotary ro-tary scrubber, actuated by a pair of traction wheelsat the rear of the carriage, car-riage, through the medium of two sprocket chains and a bevel gear. There is also a mopping brush mounted mount-ed in front of the traction wheels, with a receptacle in conjunction to catch the water after the scrubbing is accomplished. Above the rotary scrubber is a tank for containing the water and soap, with a valve to ad just the flow to the required quantity. Arrangement is also made to adjust the pressure of the bristles by varying vary-ing the height of the swiveled wheel in front of the mop. As the mopping brushes revolves it throws the water into a shield or casing partially surrounding sur-rounding it, discharging it thence to the tank. The reservoir having been filled with water of the proper temperature tem-perature and the parts adjusted, the operator has nothing to do but drive the machine back and lorth across the floor as long as there is a vestige of dirt remaining. The inventor of this labor-saver is John A. Nelson, of Sa-lina, Sa-lina, Kan. Moving the Tube Regulates the Height. to he- chanced at will the adjustment of the : i is a simple matter.

SUvorlzow considers that in the pant history of the carta and planets electrical and chemical enemies have Fastening Device for Horses. Below is illustrated a device for fastening horses securely without the coed of a bitching post, a groat convenience con-venience where a driver is compelled to make frequent stops and leave-the animal, as much valuable time may be wasted in tying the horse at every stop. The arrangement of this fastener fast-ener is such that when the animal starts forward the reins arc wound up on a spindle connected vifh one of the wheels, thus pulling the horse back until the tension is relieved. An upright supporting frame is secured played the most imporlairt parls :n remote times, and that heat energy has, become more and more important in prep. mi ion i.s the earth has assumed as-sumed j;s present condition. The heat of the earth is assumed by him to be clue to elecric currents circulating circulat-ing mostly near to the fmrl'aec; the interior of the earth, on the other hand, may bo as cold as the depths of (he ocean. Cha .ses in the slate of the earth and meteorological phenomena, phenom-ena, are attributed to electrical currents cur-rents induced by solar energy. The temperatures of the planets are considered con-sidered to depend Jess on their distance dis-tance from the sun than on their reserve re-serve of energy and on the currents which the sun induces in thorn in virtue vir-tue of their axial and orbital motions.
