Improvements in or connected with Cases or Covers for the
Driving Gear of Velocipedes and other similar Vehicles.
I, HENRY BATE of 11 Market Hill, Maldon, in the County of Essex, Cycle
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention refers to cases or covers for the driving gear of velocipedes and
the like, so constructed that the same may be readily applied and removed from
the gearing and from the framework of the machine, without in some cases, taking
or separating the gear case into several detached pieces while the construction,
and mode of application, and fixing upon the machine is improved.
I will describe an application of my invention, by way of example, to a rear
driven bicycle of ordinary type. I form the casing so as to enclose the gear
wheels, both runs of the chain, and also the lower stay tube, tubular conical,
projecting sleeves being fitted on opposite sides of the case, at the parts where the
diagonal stay tube enters and leaves the said case laterally. These sleeves should
fit the stay tube, and I may provide brackets on the case to further attach the:
same to the framework of the machine.
In order to apply such a gear case, I, according to my invention, separate:
therefrom two parts, that is one part at the front end of the case, and one part at
the rear end. Convenient lines of division of the parts are as follows: For the:
front part horizontally from the front through the centre of the aperture for the
crank axle shaft, to a proper distance rearward of same, and then say at right.
angles (vertically) thereto downwards; for the rear part in like manner, through:
the aperture for the rear wheel axle, and then vertically downwards. The case is;
then divided along its lower remaining edge. The front and rear parts, may be.
conveniently jointed or hinged to the main part, and the edges thereof fit into.
grooves (when closed) on the main part or overlap same, and thereby retain the:
fower horizontal division closed, when the gear case is in position.
The case is applied to the machine, (when the front and end parts are thrown:
open or removed) by expanding the case at its lower division, and passing same
from above over the chain, chain wheels, and lower stay tube; the sides of the case:
are then closed or sprung together, and the end and front parts replaced, and
secured by suitable means, whereby the gear case is firmly held in position.
Instead of the vertical divisions of the end and front parts, extending downwards.
the same may extend upwards, and the division longitudinally may be arranged at
the upper edge of the case. This longitudinal division may be arranged so that
one edge thereof fits into grooves on the opposed edge, or one edge may interlock :
with a reversed edge of the other part. The end and front parts may be fitted to
slide onto the case, instead of being hinged, or may be hinged and fit when closed:
into grooves on the main part.
Dated this 5th day of February 1896.

page_text: Improvements in or connected with Cases or Covers for the
Driving Gear of Velocipedes and other similar Vehicles.
I, HENRY BATE of 11 Market Hill, Maldon, in the County of Essex, Cycle
Manufacturer, 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 refers to cases or covers for the driving gear of velocipedes and
the like, so constructed that the same may be readily applied, and removed from
the gearing, and from the framework of the machine, without in some cases, taking
or separating the gear case into several detached pieces, while the construction,
and mode of application and fixing upon the machine is improved.
In order that my invention may be readily understood, I will describe with
reference to the accompanying drawing, an example of my gear case or cover, such
as would be applicable to a rear driven bicycle of ordinary type.
Similar letters of reference refer to like parts in the several figures of the
drawings aforesaid.
Fig. 1 is an elevation of one side of my improved gear case. Fig. 2 is au
elevation of the opposite side of same, that is of the side next the machine
framework.
Fig. 3 is a cross section taken on the line X Y of Fig. 1, and Fig. 4 is a similar
section on the line X1 Y¹ of Fig. 1.
Fig. 5 is a perspective view showing the gear case, with parts thrown aside and
the body of the case opened, and
Fig. 6 shews an elevation of one side of a similar gear case or cover, illustrating
a modified detail of construction.
According to my invention I form the casing A so as to enclose the gear wheels,
both runs of the chain, and also the lower stay tube, tubular conical projecting
sleeves B B being fitted on opposite sides (Figs. 1 and 2) of the case A, at the
parts where the ordinary diagonal lower tube of the machine frame, enters and
leaves the said case A. The sleeves B B₁ should fit the stay tube, and I may
provide brackets on the case A, to further attach same to the framework of the
machine, should such be found necessary or desirable; such brackets are not shewn
on the drawings, but may be of any ordinary or well known form, or such as are
now commonly employed on some known gear cases.
The body of the case A, is as shewn, divided along, or near, its bottom edge
at A as is clearly shewn at Fig. 3, while the case A is also divided on the lines A
and. A as shewn at Fig. 1, on the outside face of the case, that is the face furthest
from the frame of the machine. These divisions A' A reach respectively to the
apertures E and F for the crank shaft and for the rear, wheel axle; it is by means
of the division A', that the rear lower part of the case is allowed to pass the upper
rear stay tube, and it is by the division A that the case is passed over the crank
axle or its bearing.
From one face of the case and generally as shewn in the drawing, from that face
next the framework of the machine Fig. 2, I separate two parts, that is one part C
at the front end of the case, and one part D at the rear end. The lines of division
for the front part C extend horizontally at 'C', or approximately so, from the front
of the case A to the aperture E which is formed to admit of the passage of the
crank axle shaft, and this division C extends a proper distance rearward of same,
and then extends downwards at C.. The lines of division of the rear removable
part D extend as at D' through the aperture F for the rear wheel axle, aud down-
wards at D', while the lower edges of both these removable parts C and D

page_text: somewhat overlap the lower edge of the case; the edges at C C D D of the
parts C and D take into grooves formed on, or take over the edges of the backward
face of the case Fig. 2.
By this arrangement when the body A of the case is closed at its divided part
(at A¹), the subsequent closure of the removable parts C and D hold the case
closed.
The front and rear parts C and D may be conveniently jointed or hinged say
at CD to the main part A, as shewn at Figs. 1 to 5, and the edges thereof fit
into grooves (when closed) on the main part or overlap same, as before stated.
Instead however, of the parts C and D being thus jointed or hinged, such parts
may be fitted to slide, as shewn at Fig. 6, in guide grooves D* C* formed or fitted
on the case A, or the grooves may be made on the parts C and D and receive the
edges of the part A; it is not absolutely essential that the sliding parts C and D
should have parallel edges, but it is generally desirable.
The case is applied to the machine (when the front and end parts are thrown
open or removed) by expanding the case at its lower division all as shewn at Fig. 5,
and then passing same from above, over the chain, chain wheels, and lower stay
tube; the sides of the case are then closed or sprung together, and the end and
front parts C and D, replaced, and secured by any suitable or preferred means, say
by screws passing through the removable parts C and D, into the case body.
I have described and shown particular lines of division of the parts C and D,
by way of example, but I would have it understood, that the direction of such
dividing lines may be varied according to circumstances, and with respect to the
division A along the lower edge of the case, one such edge may if desired be
made to fit into grooves on the opposed edge, and such division may be formed
along the central part of such lower edge, instead of at one side of same.
Instead of the longitudinal division A being formed on the lower edge as shewn,
the case A may be so divided along its upper edge, and the divided parte C and D
may be at the upper part of the face of the case next the machine frame, and
when thus arranged the said case can be adjusted onto the machine from below
instead of from above.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A case or cover for the driving gear of velocipedes and other vehicles, having
a body divided lengthwise at or near one longitudinal edge (such as at A'), and
also divided in lines extending respectively, from the rear axle, and crank axle
apertures, through the edge of the case (such as at A' A'), in combination with
removable parts, which when in situ compose portions of one face of the body at
the front and rear ends thereof, substantially as described.
2. A case or cover for the driving gear of velocipedes and other vehicles, having
a body part divided lengthwise at or near one longitudinal edge, and further
divided from the rear and crank axle apertures through the said edge of the body,
in combination with removable parts, which when in situ not only compose portions
of the face of the body at the front and rear parts respectively, but also serve
when secured in position to hold the divisions of the body closed all substantially
as described.
3. The general arrangement and combination of parts composing my improved
case or cover for the driving gear of velocipedes and other vehicles, all constructed
and fitted, substantially as described and illustrated with reference to Figs. 1 to 6
of the accompanying drawings.
