page_text: 1, PATRICK FRANCIS DOOLEY, residing at Malone, in the County of Franklin and
State of New York, one of the United States of America, Gentleman, 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:
In the accompanying drawings-
Figure 1, is a front view of my improved roll grinding machine.
Figure 2, is a vertical section of one of the brackets and connecting parts.
Figure 3, is a side view of the carriage which carries the grinding wheel.
Figure 4, is a horizontal, transverse section of one of the slotted standards and a
portion of the bracket secured thereto, and
Figure 5, is a cross section of the bar which is traversed by the carriage.
Like letters indicate similar parts in the several figures.
A, designates the standards which support the mechanism, said standards being
provided with vertical, longitudinal slots in their front portions as shown. Each of
the standards carries a bracket, B, which is secured by a bolt, X, to the front of the
standard. The head, M, of the bolt is provided with a threaded aperture through
which passes a vertical, elevating screw, L, and the bolt, extending forward through
a plate, P, placed in the vertical slot, and through the bracket, is secured by a screw
and washer, so that the bracket has a swivel connection with the standard.
On each bracket, B, is placed a base plate, C, of a stand, D, the base plate having
a swivel connection with the bracket by means of a stud or neck, N, fitting in a hole
in the bracket and held in place by a screw and washer as shown. The stand, D, has
a sliding movement forward and backward on the base, C, which is provided with
guides for such purpose, this movement being effected by means of the adjusting screw,
having a hand wheel, K, and a nut connected with the stand.
Each of the stands, D, is provided, in its upper part, with an opening to receive
and hold one end of a hollow, planed bar, H, which is thus supported in a horizontal
position in front, the said bar extending through the stands and being adjustably
secured by set screws. The bar, H, being made of any desired length, the machine
may be adjusted laterally for grinding rolls of any length desired.

page_text: The vertical, elevating screws, L, are suitably mounted in the standards, A; and
extending downward, each screw passes through a threaded aperture in the head, M,
of a bolt, X, and by means of said screws, the brackets may be adjusted in elevation
to grind any roll in a frame as desired. The screws, L, are operated by means of
beveled gear wheels, U, on a shaft, V, which is provided with a hand wheel, R, 5
said beveled gears engaging with similar wheels on the upper extremities of
the screws.
On the bar, H, is placed a sliding carriage, E, the lower part of which is con-
structed with an opening through which the said bar extends, such opening forming
a bearing and the carriage being held steadily in position on the bar. The upper
part, F, of the carriage is provided with bearings for a shaft on which is placed an
emery or grinding wheel, G, and also a pulley, T. The said part, F, has a sliding
movement on the main part, E, and is adjustable forward or rearward, the movement
being effected by means of a screw provided with a hand wheel, S, and a nut, not
shown, within the carriage. During the operation the carriage moves along on the
bar, H, being actuated by means of a screw shaft, I, having bearings in the stands, D,
and passing through a nut, Y, which is secured to the lower part of the carriage-sec
Figures 1 and 3.
The screw shaft may be driven by power imparted from a rotary drum above
through straight and cross belts to the pulleys, J, on the extended end of the shaft,
the central pulley being fast on the shaft and the others loose. The belts may be
shipped by means of a rod, not shown, which is provided with adjustable collars, the
said collars being set to fix the distance to be traversed by the carriage. When the
carriage, being driven by the screw, I, comes in contact with a collar at either end of
the shipper rod, the latter slides with the carriage until the bolts are shifted and the
movement of the carriage is thereby reversed.
The shaft of the grinding wheel may be driven by means of belting, connecting
pulley, T, with a rotary drum mounted in any convenient position above.
The hollow bar, H, is provided with a number of webs, h, crossing its interior to
strengthen and render it firm and prevent any jarring or trembling motion of the bar.
during operation.
In preparing for operation, the standards, A, are bolted to the frame of the machine
carrying the rolls to be dressed, by means of the inner part having the face, Q, (see
Figure 4) and which is at right angles with front part, Z, the plate, P, being shown
in the slot of the standard, and supplementary plate, P₁, against the back of the front
part, Z; the grinding wheel is adjusted to the roll by raising or lowering brackets, B,
carrying bar, H, the said bar being brought into alignment with the axis of the roll
by means of the screws with hand wheels, K, and the shipper rod is adjusted according
to the length of surface on the roll to be ground. The shipper rod, or the collars
thereon, may be moved during operation if desired, and if it is desired to adjust the
bar, H, at either end, in its elevation, either of the gear wheels, U, may be thrown
out of engagement for such purpose. The depth of dressing by the grinding wheel is
regulated by means of the screw with hand wheel, S, by which the wheel is moved to
or from the roll.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what
I claim is:
1. In machines for grinding rolls, the combination of the vertical standards, A,
adapted to be secured to roll frame, the brackets, B; vertically movable on said
standards, the non-revoluble longitudinal bar, H, connecting the said brackets, the
traversing carriage mounted on said bar, and the shaft journaled in said carriage and
having the emery wheel and connections to rotate the same, substantially as
described.
2. The combination of the vertical standards, A, the brackets movable thereon, the
vertical screws journaled in said standards and engaging said brackets, the non-revoluble
bar connecting the brackets, the traversing carriage having. the grinding. apparatus

page_text: and mounted on said bar, and the screw, I, engaging said carriage and adapted
to move the same on the bar, substantially as described.
3. The combination of the standards having the vertical slots, the plates, P,
arranged in said slots, the brackets, B, the bolts, X, connecting said brackets to said
plates and having the heads, M, the vertical screws, L, journaled in the standards and
engaging the heads, M, the non-revoluble bar, H, connecting the brackets, and the
traversing carriago mounted on said bar and having the grinding apparatus,
substantially as described.
4. The combination of the standards, A, the vertically movable bar, H, connected
thereto, the carriage, E, mounted on said bar and having the part, F, the screw, S, to
move said part at right angles to the bar, the shaft journaled in part, F, and having
the emery wheel and pulley, T, and the screw, I, journaled in bar, H, and engaging
the carriage to traverse the same on said bar, substantially as described.
5. The combination of the standards, A, the vertical movable brackets, B, secured
thereto, the stands, C, swiveled to said brackets, the screw actuated stands, D, movable
on said stands, C, the bar, H, connecting stands, D, and the traversing carriage
mounted on said bar and having the grinding apparatus, substantially as described.
6. The combination of the vertical standards, A, the vertical screws, L, journaled
in said standards, the horizontal shaft, V, the mitre gears connecting said shaft to
screws, L, the brackets, B, guided on standards, A, and engaged by screws, L, the
non-revoluble bar, H, supported on said brackets, and the traversing carriage on said
bar and having the grinding apparatus, substantially as described.
