I, JAMES GRIEVE LORRAIN, of Norfolk House, Norfolk Street, Strand,
London, W.C., in the County of Middlesex, Chartered Patent Agent, do hereby
declare the nature of this invention to be as follows:-
My invention relates particularly to means for supporting the reciprocating parts
of mechanism, such for example as saws, planers, and typewriters, and for adjusting
the position of the said reciprocating parts and or of the parts supporting the same,
the object being to support reciprocating parts of machinery in such manner as to
reduce friction to the greatest extent and to allow the least possible deviation of
the reciprocating part from its path.
In the accompanying drawings:
Figure 1 is a plan of one specific mechanism embodying my invention.
Figure 2 is a vertical section on line a-b of Figure 1.
In said drawings, A is any suitable base. B is the part to be reciprocated in
the direction of the arrows on Figure 1. C, C, are rails located at each side of the
part B. At each side, the part B is provided with a longitudinal channel b.
DD are wheels arranged in a horizontal plane and having a tapering periphery
extending into the channels b. At each wheel the rails C have formed in them a
recess C; and the wheels D are located in said recesses. Each of said wheels has
an axle D' rigid therewith and terminating in cone shaped ends. Above and
below said axle plugs D2 are screwed through portions of the rail above and below
the cavity C in line with the axles D'; and each such plug has a cavity into
which the adjacent end of the axle extends. All of said plugs may be screwed up
and down to give to the wheels D an accurate and firm adjustment. Each wheel
may be thus held so as to wholly prevent movement other than rotation, and each
wheel may be raised or lowered in proper alignment with the other wheels, and all
the wheels may be raised or lowered to give to the part B a precise adjustment.
The lateral adjustment of the part B is effected by shifting the wheels D at one
side of said part B horizontally towards or from said part. This is done by
shifting one of the rails C laterally. The rail C at the upper portion of Figure 1
is shown as being secured immovably to the base A, while the rail C at the lower
portion is shown provided with mechanism for shifting it. Ears C² extend
horizontally from said rails C over the base A, and each such ear is provided with
a slot c² elongated at right angles to said rail; and a screw C³ extends through
each of said slots. When said screws are tightened, said rail is held immovably.
After loosening said screw, said rail may be moved toward and from the part B
after which said screws may, be again set. To provide for a closely measured and
positive movement of said rail toward and from the part B I have provided in front
of the latter a post E secured to the base A; and through said post a screw bolt E'
is threaded horizontally with its forward end extending loosely through the
block E2 which is secured to or is a part of said rail, C. At each side of said
block E said screw bolt has a shoulder or collar e which is larger than the

page_text: opening through said block. Thus said bolt engages said block E at each side of
the latter. When said bolt is retracted from the post E said screw bolt draws on
the block E2 and moves it and the said rail C away from said part B. Ou turning
said screw bolt forward, said block E2 and said rail C are moved toward the
part B, so that the latter is held more closely by the wheels D. Said screw bolts
are to be operated only after releasing the screws C³, and after an adjustment of
the said rail has been effected by means of the screw bolts E' the screws C³ are to
be tightened to hold said rail in the new position.
The reciprocating part B, may be in the form of the part shown in the
drawings or of any other form, and it may be reciprocated by the hand or by
mechanism.

I, JAMES GRIEVE LORRAIN, of Norfolk House, Norfolk Street, Strand,
London, W.C., in the County of Middlesex, Chartered Patent Agent, 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 particularly to means for supporting the reciprocating parts
of mechanism, such for example as saws, planers, and typewriters, and for adjusting
the position of the said reciprocating parts and or of the parts supporting the same,
the object being to support reciprocating parts of machinery in such manner as to
reduce friction to the greatest extent and to allow the least possible deviation of
the reciprocating part from its path.
In the drawings left with the Provisional Specification:
Figure 1 is a plan of one specific mechanism embodying my invention.
Figure 2 is a vertical section on line a-b of Figure 1.
In said drawings, A is any suitable base. B is the part to be reciprocated in
the direction of the arrows on Figure 1. C, C, are rails located at each side of
the part B. At each side, the part B is provided with a longitudinal channel b.
DD are wheels arranged in a horizontal plane and having a tapering periphery
extending into the channels b. At each wheel the rails C have formed in them a
recess C₁; and the wheels D are located in said recesses. Each of said wheels has
an axle D' rigid therewith and terminating in cone shaped ends. Above and
below said axle plugs D2 are screwed through portions of the rail above and below
the cavity C in line with the axles D¹; and each such ping has a cavity into
which the adjacent end of the axle extends. All of said plugs may be screwed up
and down to give to the wheels D an accurate and firm adjustment. Each wheel
may be thus held so as to wholly prevent movement other than rotation, and each
wbeel may be raised or lowered in proper alignment with the other wheels, and all
the wheels may be raised or lowered to give to the part B a precise adjustment.
The lateral adjustment of the part B is effected by shifting the wheels D at one
side of said part B horizontally towards or from said part. This is done by
shifting one of the rails C laterally. The rail C at the upper portion of Figure 1
is shown as being secured immovably to the base A, while the rail C at the lower
portion is shown provided with mechanism for shifting it. Ears C² extend

page_text: horizontally from said rails C over the base A, and each such ear is provided with
a slot elongated at right angles to said rail; and a screw C³ extends through
each of said slots. When said screws are tightened, said rail is held immovably.
After loosening said screw, said rail may be moved toward and from the part B
after which said screws may be again set. To provide for a closely measured and
positive movement of said rail toward and from the part B I have provided in
front of the latter a post E secured to the base A; and through said post a screw
bolt E¹ is threaded horizontally with its forward end extending loosely through
the block E which is secured to or is a part of said rail, C.
At each side of said
block E' said screw bolt has a shoulder or collar e' which is larger than the
opening through said block. Thus said bolt engages said block E' at each side of
the latter. When said bolt is retracted from the post E said screw bolt draws on
the block E' and moves it and the said rail C away from said part B. On turning
said screw bolt forward, said block E' and said rail C are moved toward the
part B, so that the latter is held more closely by the wheels D. Said screw bolts
are to be operated only after releasing the screws C³, and after an adjustment of
the said rail has been effected by means of the screw bolts E¹ the screws C³ are to
be tightened to hold said rail in the new position.
The reciprocating part B, may be in the form of the part shown in the
drawings or of any other form, and it may be reciprocated by the hand or by
mechanism.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination with a piece of mechanism to be reciprocated, of wheels
arranged at opposite sides of said part and in engagement therewith, and means for
effecting an adjustment of said wheels parallel to the plane of said wheels and
parallel to their axes, substantially as described.
2. The combination with the part, B, of wheels, D, located at each side of and
engaging said part, B, vertically adjustable mechanism supporting the said wheels
and mechanism for shifting said supporting mechanism toward and from said
part, B, substantially as described.
3. The combination with the base, A, and part, B, of rails, C, screw plugs, D³,
supported by said rails, wheels, D, supported by said screw plugs and engaging
said part, B, and screw bolts, E¹, and suitable connections for shifting one of said
rails toward and from the part, B, substantially as described.
