Given more time, he'd have preferred to put the bike on the car's rack and chew up some countryside miles, touring the hills and farm lands that surrounded Parkside.
Other special types are in limited use for " rack-railways," and operate either by engagement of gearing on the locomotive into a rack between the track rails, or by a combination of this and rail adhesion.
The rocking-bar is moved by a rack g into which a pinion on a cross-spindle j gears; the cross-spindle is moved by means of a worm-wheel into which a worm on the longitudinal FIG.

The forests have been sold, and only those landlords are prospering who exact rack-rents for the land without which the peasants could not live upon their allotments.
When an engineer has to construct a railway up a hill having a still steeper slope, he must secure practicable gradients by laying out the line in ascending spirals, if necessary tunnelling into the hill, as on the St Gothard railway, or in a series of zigzags, or he must resort to a rack or a cable railway.
In rack railways a cog-wheel on the engine engages in a toothed rack which forms part of the permanent way.
Blenkinsop placed the teeth on the outer side of one of the running rails, and his reason for adopting a rack was the belief that an engine with smooth wheels running on smooth rails would not have sufficient adhesion to draw the load required.
It was not till more than half a century later that an American, Sylvester Marsh, employed the rack system for the purpose of enabling trains to surmount steep slopes on the Mount Washington railway, where the maximum gradient was nearly 1 in 22.
The subsequent development of rack railways is especially associated with a Swiss engineer, Nicholas Riggenbach, and his pupil Roman Abt, and the forms of rack introduced by them are those most commonly used.
That of the latter is multiple, several rack-plates being placed parallel to each other, and the teeth break joint at 1, a or 4 of their pitch, according to the number of rack-plates.
Abt also developed the plan of combining rack and adhesional working, the engine working by adhesion alone on the gentler slopes but by both adhesion and the rack on the steeper ones.
On such lines the beginning of a rack section is provided with a piece of rack mounted on springs, so that the pinions of the engine engage smoothly with the teeth.
The Locher rack, employed on the Mount Pilatus railway, where the steepest gradient is nearly I in 2, is double, with vertical teeth on each side, while in the Strub rack, used on the Jungfrau line, the teeth are cut in the head of a rail of the ordinary Vignoles type.
1853); among the juniors, Anton Rack, (also an excellent translator), Louis Palagyi (Magdnyos u'ton, " On Lonely Way," &c.), Geza Gardonyi (b.
The finished cylinder is next carried to a rack and the pipe detached from it by applying a cold iron to the neck of thick hot glass which connects pipe-butt and cylinder, the neck cracking at the touch.

Fra Silvestro on the contrary gave way at mere sight of the rack, and this seer of heavenly visions owned himself and his master guilty of every crime laid to their charge.
Per second; but, unlike the older machines, in which the cutting is done in a fixed plane, the chain with its motor is made movable, and is fed forward by a rack-and-pinion motion as the cutting advances, so that the cut is limited in breadth (31 to 4 ft.), while its depth may be varied up to the maximum travel (8 ft.) of the cutting frame.
In this sight both hind and fore sights are fixed on a rigid bar pivoted about the centre; the rear end is raised or depressed by a rack worked by a hand-wheel; ranges are read from the periphery of a drum; the fore-sight and leaf of the hind-sight are provided with small electric glow lamps for night firing.
245) a rack I, fixed to the carriage, caused a pinion H on the gun to revolve.
A rack, to work with a circular wheel, must be straight.
To work with a wheel of any other figure, its section must be a rolling curve, subject to the condition that the perpendicular distance from the pole or centre of the wheel to a straight line parallel to the direction of the motion of the rack shall be constant.
Sliding Contact (direct): Teeth of Wheels, their Number anc PitchThe ordinary method of connecting a pair of wheels, or wheel and a rack, and the only method which ensures the exaci maintenance of a given numerical velocity ratio, is by means of i series of alternate ridges and hollows parallel or nearly parallel t(the successive lines of contact of the ideal smooth wheels whon velocity ratio would be the same with that of the toothed wheels The ridges are called teeth; the hollows, spaces.
In order that a pair of wheels, or a wheel and a rack, may work correctly together, it is in all cases essential that the pitch should be the same in each.
Sliding Contact: Forms of the Teeth of Spur-wheels am Racks.A line of connection of two pieces in sliding contact is line perpendicular to their surfaces at a point where they touch Bearing this in mind, the principle of the comparative motion of pair of teeth belonging to a pair of spur-wheels, or to a spur-whee and a rack, is found by applying the principles stated generally ii 36 and 37 to the case of parallel axes for a pair of spur-wheels, am to the case of an axis perpendicular to the direction of shifting for wheel and a rack.
It also determines the forms of the teeth of straight racks, if one of the centres be removed, and a straight line EIE, parallel to the direction of motion of the rack, and perpendicular to CilCi, be substituted for a pitch-circle.
The teeth of a rack, of the same, set, are traced by rolling the rolling curve on both sides of a straight line.
Intermittent LinkworkClick and Ratchet.A click acting opon a ratchet-wheel or rack, which it pushes or pulls through a certain arc at each forward stroke and leaves at rest at each backward stroke, is an example of intermittent linkwork.
On the following day she was taken to the Tower and racked; according to Anne's own statement, as recorded by Bale, the lord chancellor, Wriothesley, and the solicitor-general, Rich, worked the rack themselves; but she "would not convert for all the pain" (Wriothesley, Chronicle i.
As quit rents were customary and not rack rents, the successors of those who had redeemed their services were gaining the whole surplus in the value of goods and labour as against money, while the successors of those who had commuted their right to claim services for certain sums in money lost all the corresponding difference.
The rack-rented peasantry found no protection in the law courts until 1859, when an act was passed which restricted the landlord's powers of enhancement in certain specified cases.
