on the Rails.
I, FREDERICK NEWHOUSE of N° 96 Bancroft St., Toledo, in the County of Lucas,
State of Ohio, U.S.A., Machinist, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention relates to speed increasing devices for locomotives; and it has for
its object to provide a device of the character named, which shall be simple, strong
and durable in construction, thoroughly effective in operation, and which can be
easily applied to the locomotive and tender.
With these objects in view, the invention consists in so connecting the locomotive
and tender that, when they are in motion, the tender can be elevated sufficiently.to
throw a portion of its weight upon the locomotive and thus increase the friction of
the locomotive drive-wheels and prevent any slipping of the same upon the track;
and it further consists in the peculiar construction and combination of parts, sub-
stantially as herein-after fully set forth and specifically pointed out in the claims.
In the accompanying drawings:
Fig. 1 is a side elevation of my improved speed increasing devices for locomotives,
showing the same applied to the beds of the locomotive and tender.
Fig. 2 is a longitudinal sectional view on the line x-x of Fig. 1.
Fig. 3 is a like sectional view on the line y-y of the same figure.
Fig. 4 is a detail view of the draw bar.
Fig. 5 is a detail view of the elevating bar.
Fig. 6 is a detail view of one of the binge-plates and
Fig. 7 is a transverse section on the line z-z, Fig. 3.
Referring to the drawings, in which like letters of reference indicate corresponding
parts in the several figures of the drawings 1
A designates a portion of the locomotive bed, B the bed of the tender and C.
D the supporting-brackets suspended from the beds of the locomotive and tender,
respectively, and securely bolted thereto and each provided with a horizontal arm.
E designates a pivot pin or bolt rigidly secured to the locomotive bed A and
extending downwardly therefrom and passing through an opening in the arm of
the bracket C, the lower end of the bolt receiving a fastening-key e, see Fig. 1.

;

page_text: F designates a similar bolt or pin rigidly secured to the tender bed B and passing
through an opening in the horizontal arm of the bracket D. G H designates
hinge-plates, which normally rests on the horizontal arms of the brackets CD,
respectively.
The plate G has an eye or opening, through which passes the bolt E, and the
plate H has a similar eye to permit the passage of the bolt F, the plates being thus
pivotally connected or hinged to the bolt and capable of a lateral horizontal
swinging movement thereon. Each of the plates is bifurcated at the end opposite
to that end which is connected to its pivot bolt, so as to provide two arms g
separated by an intervening slot, and these arms are perforated transversely for the
· passage of pivot pins or bolts h h¹ to connect the arms of the said hinge-plates to
the draw bar I and the elevating adjusting arc-shaped bar or casting J, as will be
herein-after more fully set forth.
The draw bar I is pivotally connected at its front end to the arms of the hinge-
plate G, the front end of the draw-bar being fitted between the arms and the
headed pivot pin or bolt / passed through the arms and draw-bar and receiving a
nut i, the draw-bar being free to move vertically between the arms of the hinge-
plate. The rear end of said draw-bar is also pivotally connected to the arc-shaped
elevating-bar J, and is adjustable vertically therein as will be presently described.
The arc-shaped elevating bar J is cast or formed in two longitudinal sections, the
lower ends of which have meeting-lugs j through which passes a bolt to secure the
lower ends of the sections together. The longitudinal sections of the elevating-bar
are arranged a short distance apart so as to provide an intervening space for the
reception of the lower end of the draw bar I, and cach have two or more apertures
or openings; which coincide and permit the passage of a shaft or bolt K.
The lower rear end of the draw bar I is enlarged and has a longitudinal slot 2¹,
and this slot coincides with the registering apertures of the elevating bar sections
and the shaft or bolt K passes through these apertures and slot and receives a
key to connect the parts together.
By means of the slot in the lower end of the draw-bar, the necessary play
between the draw-bar and the adjusting-bar is permitted, when the locomotive is
moving backward, and thus the danger of breaking the parts in the retrograde
movement of the locomotive and tender is avoided.
It will be observed that the hinge plates are capable of a lateral swinging play
or movement in a horizontal plane on the pivot pin or bolts; and that the draw-
bar and adjusting bar are vertically adjustable at the point of their pivot connection
with the hinge-plates. A double hinge joint or connection between the several
parts is thus provided, which allows of the free requisite movements of the parts,
when the locomotive and tender are in motion, without undue wear or strain on
the parts.
The lower end of the arc-shaped elevating bar J is connected by a chain or other
connection (not shown) to a suitable device in the locomotive-cab within convenient
reach of the engineer, and when the arc-shaped bar is forced upwardly, it will
elevate the pivot shaft or bolt K and the front end of the tender, and superimpose
a portion of its weight on the rear end of the locomotive bed, and thus force the
wheels of the latter into closer and firmer engagement with the track and hence
increase the speed of the locomotive and prevent any slipping of the wheels thereof
on the track.
The arc-shaped adjusting bar J is provided on its rear face with a pivot lug L,
which is provided on its upper edges with lateral flanges l. A plate M is fitted on
the lug L, and said plate bears against the rear face of the arc-shaped elevating
bar. The adjusting plate M is slotted longitudinally at its side edges, and through
these plates pass bolts M³, fitted in apertures in the lateral flanges of the pivot-lug
and receives a nut m, whereby the plate can be adjusted back and forth to vary
the angle or incline of the arc-shaped elevating bar, which works on the pivot pin
or bolt as a centre.

page_text: The laterally adjustable plate is provided on its rear edge with spaced apart
downwardly projecting flanges or lugs n n, which have threaded sockets, in which
the adjusting bolts N work and bear against the rear face of the lug L on the
adjusting bar J to hold the plates M and the connections with the elevating bar
from rattling noise.
.
The rear end of the laterally-adjustable plate M is hollowed out as at o, and the
lower end of the king-bolt or pin F bears against the same and the pivot-lug L.
O designates a take-up rod or bar pivotally connected at its front end to the
pivot-lug L and supported at its rear end in the slotted arm o¹ of a supporting
bracket P which is bolted to the bed of the tender at or near its rear end. The
rear end of the take-up rod is threaded and receives an adjusting or tightening
nut P¹ and by means of this peculiar arrangement of the threaded rod and its
tightening nut and bracket, the slack between the tender and the locomotive can'
be taken up, it being understood that any other coupling than the draw-bar and
its several connections be dispensed with.
:
The operation of my invention is obvious.-When the elevating, bar G is raised,
it elevates the front end of the tender and superimposes a portion of the weight
thereof on the rear end of the locomotive, which causes the wheels of the latter to
be brought into closer and firmer contact with the track and thus prevents them
from slipping and hence increases the speed thereof.
Any suitable means may be employed to operate or force the elevating bar
upwardly to raise the tender. As for instance a chain or link may be connected
to an eye thereof and lead to the cab of the locomotive. When it is desired to
remove the weight of the tender, the elevating-bar is drawn forwardly and the
tender is lowered.
R designates a brace-arm, rigidly secured to the tender-bed and bearing at its
lower end on the tension-rod O at the point, where it is bent, to keep the same
normally pressed downwardly.
The apparatus above described is simple in its construction, may be readily
applied, is thoroughly effective in operation, and strong and durable.
