COMPLETE SPECIFICATION.
Bottle Finishing Machines.
We, CHRISTIAN FREDERICK LENG and CHARLES LENG, residing at 1919 Mary
Street, in the City of Pittsburg, County of Allegheny, and State of Pennsylvania,
U.S.A., Glass and Glass Tool Manufacturers, 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:-
Our invention relates to an improvement in bottle neck finishing machines and
consists in a set of revolving dies for finishing the outer portion of the neck and a
tapering guide bar having a rotary movement in an opposite direction to that of the
dies for finishing the inner portion of the bottle neck, together with certain details of
construction and combination of parts as will be fully set forth hereinafter..
In the accompanying drawings:
Figure 1, is a plan view of our improved bottle finishing machine, partly shown in
section the better to show its working parts.
Figure 2, is a side elevation of the same.
Figure 3, is an enlarged sectional elevation through a portion of the face plate,
showing the manner of securing and adjusting the dies.
Figure 4, is an enlarged detailed sectional elevation, showing the manner of attaching
the guide bar, and face plate in position.
To put our invention into practice we provide a frame A, of suitable size and form of
construction and firmly attach the same to a bench b. Mounted on this frame A, and
secured in proper bearings i, are two shafts c, d, the one c centrally located within
the other d. At the rear extremity of each of these shafts c, d, are secured bevel
pinions e, each of which meshes with a pinion properly mounted in a suitable
bearing g, on a short shaft h. This arrangement of gearing serves to revolve the two
shafts c, d, in opposite directions. Secured to the forward end of the outside shaft d,
is a disk or face plate k, in which two finishing dies, are secured by passing the same
through openings m, in the disk k, and adjusting the same by means of set-screws o,
placed through the perimeter of the plate k. Attached to the forward end of the
inner shaft c, by means of a screw thread, is a tapering guide bar », which serves to
enter the bottle t, properly into the dies 1, and to finish the inner portion of the neck
of the same.
A small rectangular plates, loosely secured between the bar r, and face
platek, prevents the dies from closing more than necessary to finish the neck of the
bottle. At the rear of the face plate k, is a loosely fitting conical shaped clutch,
which when moved forward on the outside shaft d, by means of a rod wc, presses the
dics together, over the neck of the bottle t placed between the same. A tight and
loose pulley y, secured to the outside shaft d, between the bearings i of the same,
affords a means for operating the machine.
These dies 1, guide bar r, and the rectangular plate s, may be detached from the
machine and others of different shape substituted, or the same dies 1, may be adjusted
towards or away from each other by the set-screws o, to finish the necks of large or
small bottles.
By this construction and operation the bottle is prevented from turning in the
dies, when finishing the same. The guide bar r, revolving in one direction and the
dies in an opposite way equalize and counteract the friction of each other thereby
preventing a round bottle from turning and obviating the necessity of a device for
clamping the same.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, we declare that what we claim is :-
1

page_text: shafts c, d, the one centrally located within the other, and a means for revolving the
same in opposite directions, the dies adjustably attached to the face plate k, secured
to the forward end of the outside shaft d, and a device for opening and closing the
same the guide bar », and rectangular washer s secured to the inner shaft c, substan-
tially as and for the purpose described.
2. In a machine for finishing the necks of bottles, the combination of the oppositely
rotating concentric shafts, and the dies carried by one of said shafts for finishing the
exterior surface of the neck of the bottle, substantially as and for the purpose
described.
3. In a machine for finishing the necks of bottles, the combination of the oppositely
rotating, concentric shafts, the finishing dies carried by one of said shafts, and a
guide carried by the other shaft to centre the neck of the hottle between said dies,
substantially as and for the purpose described.
.4. In a machine for finishing the necks of bottles, the combination of the concentric
oppositely rotating shafts, a face-plate carried by one of the shafts, the finishing dies
movably mounted in said face-plate, and a sliding device for simultaneously adjusting
said dies, substantially as and for the purpose described.
5. In a machine for finishing the necks of bottles, the combination of the concentric,
oppositely rotating shafts, a face-plate fixed to one of said shafts, the finishing dies
loosely mounted in the face-plate, a conical sliding sleeve adapted to impinge against
all of said dies to simultaneously adjust the same, and a stop for limiting the inward
movement of the dies upon the neck of the bottle, substantially as described.
6. In a machine for finishing the necks of bottles, the combination of the concentric
rotary shafts, a forwardly projecting guide carried by one of the shafts, a face-plate
fixed to the other shaft, the finishing dies loosely fitted in apertures in said face-plate,
and adjusting screws for moving the dies laterally of one another, substantially as
described.
7. In a machine for finishing the necks of bottles, the combination of the concentric
rotary shafts each having a pinion secured thereto, which mesh with another pinion,
a face-plate fixed to the hollow shaft and carrying the movable finishing dies, a sliding
conical sleeve for simultaneously adjusting the dies, and a tapered guide fixed to the
inner shaft and projecting forwardly beyond the face-plate to centre the neck of the
bottle between the dies, substantially as described.
