A Machine for Sizing or Sorting Articles of a like Species.
I, PAUL PONDORF, of Goessnitz Saxe-Altenburg, in the Empire of Germany,
Doctor of Science, 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 thereof reference being had to the drawings
hereunto annexed and to the figures and letters marked thereon that is to say;-
The invention has for its object to separate or sort articles of the same kind
according to size, metal cartridge cases being here taken as an example, and its
method of sorting consists in eliminating all articles that do not come within the
limits of a predetermined standard size.
In the accompanying drawings:-
-
Figure 1 is a plan or top view partly in section representing a machine con-
structed according to the present invention.
Figure 2 is a side view thereof.
Figures 3 are diagrammatic views showing the various cams and their relation
to some other parts.
Figure 4 is a separate view of the toothed segment and co-acting wheel.
Figure 5 is a separate view of the driven chain wheel.
Figures 6 are respectively a side view and end view of a portion of the feed
chain and
Figures 7 are detail views of parts.
The construction and operation of the machine are as follows;-
Upon a foundation or bed-plate a are erected four parallel walls and c c¹,
arranged in pairs, one pair, 661, Figures 1 and 2 constituting a support or rest
for the bodies to be measured or gaaged while the other pair cc¹ serve to guide
the measuring instruments and ejectors.
The machine is driven by means of a strap (not shown) and a pulley & fast upon
the shaft g as shown in Figures 1 and 2 which shaft thereby receives rotary
motion from any suitable source of power.
This rotary motion is transmitted to the shaft g¹ by means of the bevel
wheels ff Figure 1 and upon said shaft g' is rigidly secured a toothed segment ¹,
Figure 1, which revolves therewith.
At a given point in each revolution of the shaft g', the toothed segment ¹
comes into gear with the toothed wheel k as shown in Figures 1 and 4 which is
fixed upon the shaft Figure 1, thereby causing said wheel and shaft 2 to
move through one sixth of a revolution together with the chain-wheel Figures 1
and 5 also mounted upon the said shaft g, by which means the endless chain m
Figures 1 and 6, is each time the segment gears with the wheel & moved
longitudinally forward a pre-determined distance."
A chain-wheel is arranged at the end of the machine opposite to 7, for the
purpose of properly guiding the chain in its movement.
The chain carries forks n', Figures 6 arranged vertically at suitable distances
apart, each space corresponding to the distance traversed by the chain at each
movement caused by the one sixth revolution of the wheel the chain n and
forks serving to convey the bodies to be sorted which are assumed to bo
cartridge cases in the present instance from one holder to another.

page_text: The holders are small triangular notches formed in the supporting walls 6 61
and numbered 1, 2, 3, and 4 Figure 1.
Each cartridge case is first placed in the holder 1, horizontally and transversely
of the chain n after which the operations proceed as follows:-
Mounted upon the shaft g Figure 1 and rotating therewith are cams ; u, u², u³
and so on, the cams u, 2 being formed as shown in Figure 3, while the
cams take the shape indicated in Figure 3.
The cartridge is inserted, as the pusher or slide o, and concurrently with it
the parts o¹, and are retracted by the cams m, n, u² and w³.
The springs q, q, q² 2 cause the pushers or slides to advance. Figure 1, at
the moment when the depressed parts of the cams come into action with the
pushers.
The pushers o and p advance gradually, whereas the ejectors o¹ and p³ move
forward quickly, the two kinds of motion resulting from the shapes of the
cams Figures 3 and the said pushers and being measuring instru-
ments, while o¹ and pare ejectors.
The pushero moves forward slowly, and with a certain amount of resiliency
and in so doing pushes the cartridge case towards the stationary wall e Figure 2,
rising above the wall b.
To the pusher or slide o are fixed lugs r r which are perforated and threaded and
carry a small screw 2 Figures 1 and 2.
If the cartridge case is of the proper length, or less than that length, the
pusher or slide will advance sufficiently far for the point of the screw to
strike the arm s of the double armed levers which is pivotally mounted at $3
with capability of horizontal movement thereby causing the arms to move a short
distance.
The end of the other or long arm will consequently be moved from the right
to the left and inasmuch as the proportion of the length of the arm s to that of
the arm s² is as 1 is to 10, such movement of the arms will be ten times greater
than the movement of the arm s¹.
at
The end of the arm 2 is situated under the lever which is pivotally mounted
with capability of vertical movement and the short arm t¹ of which terminates
in an incline 4 Figures 1 and 2 and left hand view in Figure 7.
Owing to the movements of the arms s' and the latter of which ascends the
incline just mentioned, the short arm is raised and the long arm Figures 1
and 2 depressed.
The arm carries a vertical pin e, which descends together with said arm and
takes up its position in front of a nose or projection of the ejector pusher or
slide o Figures 1 and 2.
This pin thus serves to retain the pusher of which is drawn back in its place,
in opposition to the spring q' even after the cam ul has released said pusher o¹.
In the meantime the pusher o has been drawn back by the rotating cam u and
the chain performs a longitudinal movement and, in so doing, carries the
cartridge case from holder 1 to holder 2 by means of the forks, the cartridge
case remaining at rest in such holder 2 until the chain advances it further namely
to holder 3.
If however the cartridge case should be too long, the pusher o as it moves up
to holder 1 comes against the cartridge case and therefore cannot advance suffi-
ciently to enable the screw to actuate the arms of the lever s so that the arms s
of the lever s and t¹ and 2 of the lever tin that case remain in their initial
positions; in other words the pin v does not hinder the ejector slide or pusher o
from springing forward.
Accordingly the sudden forward movement of the ejector slide or pusher o¹
caused by the spring gl takes place said movement being permitted by the position
which the can then occupies at the moment when the cartridge case has
been transferred from holder 1 to holder 2 and said case is thereby expelled from
the machine through an aperture provided in the wall e coinciding with holder 2.

page_text: It will thus be seen that cartridge cases which are too long cannot move past
the ejector whereas cases of normal or less than normal length are carried
along to holder 3; here they are again measured by the pusher and the position
of the ejector p¹ is so adjusted that it expels those of the cases reaching holder 4
which are too short.

The measuring pusher p advances to the cartridge case exactly as did the
pusher in the preceding instance and if the length thereof be normal the small
screw will not engage the arm of the lever i; should however the cartridge
casa be too short then the pusher will advance far enough to enable the
screw to engage the arm whereby the lever i is swung round upon its axis
in a horizontal plane Figure 1.
The arm is now situated over the arm m² of lever m Figures 1 and 7, so that
as said arm runs up the incline m of the arm m² it depresses the same
Figure 7 turning the lever m upon its axis m³ while it raises the arm m¹ and with
it the pin l, which up to now retained the ejector slide or pusher p by means
of a nose or catch from which it has been released by the cam Figure 1.
The pin therefore has now released the ejector pl by reason of the cartridge
case being too short but the cam ³ still keeps back the ejector p until the
cartridge case which is being measured reaches holder 4.
At this juncture the ejector pusher or slide 1 is liberated, and it accordingly
springs forward and drives out the cartridge case found wanting in length through
an aperture provided in the wall e opposite the holder 4.
A variety of measurements may be taken in the same way the cartridge cases
the size of which is found to be in conformity with the standard, being in all
cases carried further along and brought in front of fresh measuring devices
while those which prove deficient in size are expelled, the same deficiencies of size
always causing them to be thrown out at the same places so that cartridge cases
which are too long, too short, too wide too narrow or otherwise inaccurate are
received at the same time in suitable receptacles provided for each kind respectively.
The cams uu on the shaft g the cam w on the shaft gl and the toothed seg-
ment come into operation successively as illustrated in Figure 3^, that is to say
at the moment when the toothed segment has performed its operation fresh
cartridge cases take up their positions in front of the measuring pushers or
ejectors as the case may be and the depressions in the cams u u³, Figures 3*
and instantly permit the ejectors op¹ to spring forward if such ejectors are
not held back by the pins so that cases of a wrong size are at once ejected.
The ejectors o p are then drawn back again by cams u³ and the levers s, t, i, m,
are restored to their initial positions in the manner hereinafter described.
This is accomplished by means of the cam w on the shaft g' draw rod y and
pins Figure 1 and the cams u and u² then allow the measuring pushers o
and p to advance.
The cam w draws the resilient or spring controlled rod y from left to right
so that the pins y' y strike the levers s and restore them to their initial positions.
This occurs immediately after the ejectors have sprung forward, and as they are
receding again but before the measuring pushers begin to advance. By these
means the machine is enabled to operate in a continuous manner.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is;-
1. A machine for sorting bodies of a kindred nature according to size, the
main feature of which is that the bodies are moved intermittently by steps from
ene place of support to the next and are thus brought in front of the measuring or
gauging appliances and ejectors arranged in alternate juxtaposition; the ejectors
being released by the measuring devices whenever the body to be gauged is of
an incorrect size so that any bodies of other than standard dimensions are ejected
substantially as herein shown and described and for the purpose stated.
