DOUBLE FRICTION HORSE POWER HOISTER.
We illustrate below an improved Horse Power Hoisting machine, for operating a boom derrick in quarrying and the laying of heavy stone. It is built strong and durable in every respect, and has two friction drums, one to handle the load, and the other for raising and lowering the boom. The friction of these drums are of the latest improved pattern, having a small percentage loss of power in operating them, and being constructed to avoid sticking in any kind of weather. The advantage of friction drums on a horse power can be readily seen in that the clutch can be thrown in or out of gear instantly without stopping and backing the horse. The drums can be operated together or separately, the boom can be raised or lowered at the same time that the main fall is being operated. The main drum is provided with a back gear which when thrown in increases the speed five times, thereby giving the operator power to handle the light loads quickly and without unnecessary loss of time. The combinations in this machine enable the operator to use the power of the horse to the best advantage in handling heavy loads slowly and light loads quickly. The machine is provided with foot brakes and is built without the boom drum when so ordered.
This machine is one of a full line of hoisting machines built by Dobbie, Stuart & Company, Niagara Falls, N. Y., who also have on the market a complete line of derricks operated by steam, horse and hand power, catalogue of which will be sent upon request.
Judge Bryant, of the United States Circuit Court for the eastern district of Texas, has recently granted a preliminary injunction restraining the Galveston Construction Company and O'Connor, Laing & Smooth, and Sullivan & Field from Infringement of the Knox patent, owned by The Knox Rock Blasting Company of Pittsburg (sic), Pa, It appeared in the case that the defendants were using the Knox method of blasting in their quarry in Texas for blasting stone used in the construction of the jetties at Galveston, and after argument of the case the court decided the patent to be valid, and ordered that the defendants be enjoined.
PATENT ADJUSTABLE COMET CRUSHER.
The Comet Crusher is of the gyratory type in which a conical head
mounted upon a nearly vertical shaft is caused to gyrate within a
fixed heavy inverted conical hopper. The material to be reduced
being fed into this hopper is rapidly crushed smaller and smaller
as it decends (sic) between the concave and convex conical
surfaces, the latter opening and closing upon the former by
gyration as the head revolves, until the fine material falls
through the orifice between them. This orifice is eccentric and may
be described as continuously opening and closing around a circle,
giving a peculiar cross breaking action which rapidly disintegrates
the material. The breaking strains are contained within the massive
hopper which is supplied with hard liners as renewable wearing
parts. The gyrating shaft bears upon a step in an oil cup and is
driven through bevel gears with a comparatively small expenditure
of power. Should a steel tool fall into the hopper and resist
breakage, the working parts are protected from damage by readily
replacable (sic) break pins through which the main pulley drives a
clutch feathered upon a horizontal shaft. 
The parts described, as well
as the new adjustable feature patented August 20, 1895, are shown
in the accompanying sectional cut. The adjustment accommodates any
amount of wear and provides for product of different sizes from the
same machine, by raising and lowering the head, which can be done
without stopping the machine. The angle of gyration of the shaft
remains the same up or down, as the bearings encircling upper and
lower ends of the shaft are not changed. The mechanism for
adjustment is a correct and reliable piece of mechanical design.
The shaft has a toe bearing upon button and stop inclosed in an oil
cup at the top of a movable ram, the lower end of which carries a
chain wheel idler. This is lifted or lowered by the winding of a
chain drum, on the same shaft with a worm wheel operated by worm
and hand wheel, the loop of the chain being carried by an idler on
the worm wheel shaft. This is found to work perfectly in practice.
The hand wheel is provided with a ratchet and awl which prevents
motion from jar, and an index with arrows shows the direction of
turning to produce finer or coarser material. The merit of the
whole design is not only that the crushing head can be adjusted,
but that it can be readily given a great range of adjustment
without any inconvenience of hard screwing, lifting or jacking-up.

DO NOT NEGLECT
the opportunity to visit dear friends during the holidays. The Nikel Plate Road, always catering to the wants of the traveling public, the popular low rate line along the south shore of Lake Erie, will sell tickets at greatly reduced rates on December 24th, 25th, 31st, and January 1st, good returning until January 2. For further particulars apply to J. Y. Calahan, Gen'l. Agent, 111 Adams street, Chicago, Ill.
THE CENTRAL PLANT COMPRESSED AIR SYSTEM
The Ingersoll-Sergeant Drill Company have just received a large order for a complete plant of air compressing machinery for running drills, engines, pumps, etc. on the Jerome Park Reservoir work, New York. The contract for the construction of this reservoir was awarded to Mr. J. B. McDonal at $5,473,060. It involves the removal of upwards of 3,000,000 cubic yards of rock. The contractor has since the letting of the work made a thorough investigation looking to determination of the question whether or not machinery for excavation can best be run by steam, or from a central compressed air plant. The central plant system has been adopted as the best and cheapest, the saving in expense being largely in labor and fuel. The plant made by the Ingersoll-Sergeant Drill Company, and adopted by the contractor involves the use of compound condensing Corliss air-compressors run by high-class boilers transmitting and distributing compressed air at 80 pounds pressure throughout the work. It is contemplated to use a battery of several air compressors placed side by side, the unit adopted being a duplex compressor with steam cylinders 24" and 44" in diameter by 48" stroke, driving two piston inlet air cylinders each 24 ¼" in diameter by 48" stroke. The capacity in free air of this machine being between 3,000 and 4,000 cubic feet per minute. This is a duplicate of compressors at work at the Anaconda mines in Montana where very economical results have been derived.
Of the Nickel Plate Road, equipped with the most modernly constructed day coaches and luxurious sleeping and dining cars, illuminated throughout with the famous Pintsch gaslights, and colored porters in charge of day coaches, are some of the features of this popular line that are being recognized by travelers seeking the lowest rates and fast time.

THE MOST POPULAR HIGHWAY OF TRAVEL
penetrating the principal cities of the East-the shortest line between Chicago and Boston with solid through trains to New York City via Ft. Wayne, Cleveland and Buffalo and the only line via these cities having colored porters on its first and second-class day coaches at the disposal of its patrons, is the Nickel Plate Road, whose unexceled (sic) train service and most liberal rates have long been recognized by east-bound travelers.
