A New Machine for Automatically Inserting and Rivetting Pins or
Hackle Gills in the Shells of Hollow Feed Rollers, Circular
Combs, Faller Bars, and the like.
1. WILLIAM HOLLINGWORTH, of Holme Top Mills, Little Horton, Bradford, in the
County of York, Self-acting temple maker, 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.:-
The feed rollers of certain classes of carding machines are made of hollow metal,
having pins or teeth projecting therefrom, and it has been customary to insert, such
pins through small holes made therein by manual labour, but such method of
insorting and rivetting the said pins is both slow and tedious. The object of my
invention is to construct arrange and combine a new form of machine for the purpose
of inserting detached pins or hackle gills in metal rollers and also into circular
combs and faller or other bars, used in combing and preparing fibres.
In carrying out my invention I employ any ordinary form of lathe chuck mounted
on an axis for the purpose of holding or clamping the hollow perforated metal roller
for the reception of the pins or lackle gills. This chuck is attached to a toothed
wheel mounted upon the same axis as the chuck, both of which are caused to revolve
intermittently by a connecting rod actuated by eccentric or other means.
I also
employ a horizontal rod caused to reciprocate by eccentric or other means, the front
end of such rod being provided with a finger for the purpose of forcing a detached
pin resting in a groove through a perforated hole made in the shell of the hollow
roller, and when such pin has been forced into the said hole or perforation the chuck
carrying the hollow roller is caused to partially revolve or move a tooth for the
purpose of presenting another hole opposite a corresponding pin, which is likewise
forced in by the reciprocating finger, and when one series of holes in the said hollow
roller have been filled with pins, the chuck with the perforated roller is raised
vertically so as to bring another row of holes opposite the reciprocating finger, which
holes are filled with pins as above described, when the chuck is raised a second time
to present another set of holes, and so on, one set after another, until all the holes in
the roller have been filled with pins.
In order that my invention may be better understood, I will now make reference
to the accompanying sheets of drawings illustrative thereof, wherein Fig. 1 is a front
elevation of a self acting pin inserter or rivetting machine constructed according to
my invention Fig. 2 is side elevation of the same looking at Fig. 1 (in the direction
of the arrow a) parts of which are in section for the sake of clearness. Fig. 3 is
plan view of Fig. 2, and Fig. 4 sectional detail. No. 1 represents suitable framework
for carrying the brackets 2, which supports the main shaft 3, made to revolve by the
fly wheel and "swaife" 4. The front of the framework I is dovetailed or made
with V edges for receiving another bracket which can be made to slide up and
down the bracket framework 1 by means of band lever 6 working upon a fixed stud 7
attached to frame 1, such handle 6 being slotted at 8 for the reception of the stud
or pin 9 projecting from the sliding bracket 5; such bracket, being held up by
means of a pin passing through holes 10 as shewn in dotted lines Fig. 1.
bracket 5 is made with a table 11 through which passes a vertical stud 12 on which
is mounted a ratchet or catch wheel 13, to which ratchet wheel is attached an
ordinary lathe chuck 14 provided with ordinary dogs 15, made to move to and from
the centre of the said chuck by means of a hox key, which is made to operate the
screws 16 in the ordinary manner, and which chuck of itself forms no part of my
invention. No. 17 represents a hollow feed roller such as those used in carding
engines. This feed roller is bored with oblique holes b, and it is held secure within
The

page_text: the dogs of the clutch and kept central therewith. The chuck with its hollow roller
receives an intermittent rotary motion after the insertion of a pine through one of
the holes, such intermittent motion being obtained through the medium of eccentric 18
fixed upon the main shaft 3. This eccentric works within the yoke or two uprights 19
and 20, receiving from the said eccentric an end wise or backward and forward
motion, causing the horizontal rod 21 to be moved backward and forward, in doing
which the upright rod 22, which passes through holes in the end of the horizontal
rod 21, such upright rod is also reciprocated, and as it is connected to the arm or
link 23 attached to the plate 24 placed loosely on the central stud 12, such plate 24
receives a backward and forward motion intermittently, causing the catch 25 attached
to the said plate to move the ratchet wheel 13-forward a tooth in the direction of the
arrow c, the effect of which is to present another hole opposite the plunger or finger d
hereinafter referred to. In gear with the teeth of the ratchet wheel 13 is a holding
catch 28 which holds the ratchet wheel during the time the catch 25 is turning the
said wheel around. Flat springs 29 and 30 are employed to keep both the catches
in gear with the ratchet wheel. The plunger or finger d is suitably connected to a
horizontal rod 31 attached to another eccentric 32 also mounted upon the main
shaft 3. This latter eccentric is so timed as to advance every time a fresh hole 18
is presented opposite to the point of the said finger or plunger d so that a loose or
detached pine which is inserted by the attendant in the bottom of the groove fis
forced through the perforations by the plunger as they are from time to time
presented to it. The holes in the shell of the feed roller 17 are made slightly taper,
and so also are the detached pins e, so that upon each pin being forced into one of
the holes, they are thrust tightly therein and made secure.
When the upper row of holes in the hollow roller have been filled with pins, the
second row is raised and presented in a line with the finger or plunger, and this is
done by the attendant placing handle 6 as shewn in dotted line of Fig. 1, whereupon
he places a pin or stud 34 in the holes 10, the object of which is to raise the
bracket 5, together with the chuck and hollow roller, into line with the finger or
plunger, when the operation of inserting the pins is repeated. The sectional drawing
Fig. 2 shews the finger or plunger in the position it occupies before its forward
action, whilst Fig. 4 shews the position the finger occupies after it has forced one of
the pins home into the perforated hollow roller.
By constructing and arranging a machine as herein shewn and described, loose
pins can be inserted into holes formed in hollow rollers, rings, and straight bars,
very expeditiously and with exact regularity, the point of each pin being always
equidistant from the periphery of the roller or bar, which is very desirable for the
proper execution of work under operation:
If this machine be employed to insert loose pins into faller bars, chuck would have
to be dispensed with, and the bar would be caused to travel horizontally by rack and
pinion or screw gearing.
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:-
Firstly. In a machine for inserting pins into holes of hollow rollers, rings, or
fallers, the employment of the reciprocating finger or plunger d arranged within the
said hollow roller for the purpose of forcing detached pins through the shell of the
said rollers in manner substantially as described.
Secondly. In a machine for inserting pins into holes of hollow rollers, rings, or
bars, the employment of the reciprocating finger or plunger d in combination with a
chuck for holding the said roller whilst the pins are being forced into position,
substantially as described,
Thirdly. In a machine for inserting pins into holes of hollow rollers, rings, or bars.
the employment of the reciprocating finger or plunger d in combination with an
eccentric or other equivalent device for giving intermittent motion to the said hollow
roller.

page_text: Fourthly. The general arrangement, construction, and combination of the several
parts substantially as herein shewn and described for holding hollow rollers, rings,
or bars, and for inserting pins into perforations formed therein.
