page_text: I, WILLIAM J. RICHARDS of Coaldale in the County of Schuylkill and State of
Pennsylvania United States of America Coal Miner do hereby declare the nature
of this invention to be as follows:-
:-
My Invention relates to padlocks wherein the shackle or bow is entirely discon-
nected from the lock when the lock is open; and the Invention consists of two
series of locking bolts that are arranged to engage with apertures formed in the
shanks of the bow or shackle, the bolts being turned by a centrally inserted key
which is provided with as many bits as there are locking bolts. The main portion
of the case of the lock is provided with a bottom in which there is an opening
through which the key is inserted. Upon opposite sides of the case are formed
grooves or ways into which the shanks of the shackle are inserted. Within the
case I arrange two series of bolts carried by plates that are provided with flanges,
of which one is arranged to fit close against a ridge which, in conjunction with a
second ridge forms the grooves for the shanks of the shackle while the other flanges
abut against opposite sides of the case, the parts being arranged so that the inner
edges of the opposite plates will overlap and closely approach but not touch each
other. After the plates have been inserted in the case, a cover formed with
apertures through which the shanks of the shackle pass is placed upon the top of
the case in which position it is held by rivets, said rivets serving as stops to define
the position of the plates. The bolts are, as before stated, arranged in series one
series being carried by each set of plates These bolts are formed with elongated
slots through which retaining bolts or pins are passed the bolts resting upon hori-
zontal plates and any upward movement of the bolts is prevented by guiding pins.
The inner ends of each of the bolts are made in the form of hooks and the bolts
are normally held forward by springs. The key which is employed in connection
with the lock is provided with as many bits as there are bolts in the lock and these
bits are arranged upon opposite sides of the key. The key shank is hollow, in
order that it may ride over or receive the key spindle. Just opposite the hooks of
Price 71

page_text: the bolts, the plates are formed with appropriately shaped openings which admit
the bits of the key.
In operation the key is inserted through the aperture formed in the bottom of
the lock-case, so that the key spindle will enter the bore in the key-shank; the
key is then turned so that its bits will pass through the apertures in the plates and
engage with the hooks of the bolts, and a continued motion of the key will throw
the bolts out of engagement with the apertures in the bow and into the lock-case
against the tension of the springs after which the shackle may be withdrawn from
the lock.

page_text: I WILLIAM J. RICHARDS of Coaldale in the County of Schuylkill, and State of
Pennsylvania United States of America Coal Miner do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement:―
My invention relates to padlocks wherein the shackle or bow is entirely discon-
nected from the lock when the lock is open; and the invention consists of two
series of locking bolts that are arranged to engage with apertures formed in the
shanks of the bow or shackle, the bolts being turned by a centrally inserted key
which is provided with as many bits as there are locking bolts.
Reference is to be had to the accompanying drawings forming a part of this
specification, wherein figure 1 is a central sectional view of my improved form of
lock, Figure 2 is a sectional plan view taken on line x-x of figure 1. Figure 3 is
a view of the bow or shackle, and figure 4 a side view of the key.
Similar figures of reference indicate corresponding parts in all the figures.
Although I have illustrated my improved form of padlock as being enclosed
within an oval case, it will of course be understood that the style or form of the
case is entirely immaterial, and that a square, round or other form of case could be
employed.
As illustrated in the drawings, the main portion of the case 10 is provided with
a bottom 11, in which there is an opening 121 through which the key is inserted.
Upon opposite sides of the case 10 there are formed grooves or ways 12, 12, within
which the shanks 13 of the shackle 14 ride. Within the case 10 I arrange two
series of bolts 2, carried by plates 15 that are provided with flanges 16 and 17, the
flanges 17 being arranged to fit close against one of the ridges 18, which, in con-
junction with the ridges 19 form the grooves or ways 12 within which the shanks
of the shackle ride. The flanges 16 abut against opposite sides of the case 10, the
parts being arranged so that the inner edges of the plates 15 will overlap and
closely approach but not touch each other, as is best shown in figure 2.
After the plates 15 have been inserted in the case 10 as described, a cover 20
formed with apertures through which the shanks of the shackle pass, is placed
upon the top of the case 10, in which position it is held by rivets 21, said rivets
being placed as indicated in figure 2, and serving as stops to define the positions of
the plates 15.
The bolts 2, are as before stated, arranged in series, one series being carried by
each of the plates 15. These bolts 2 are formed with elongated slots 3, through
which there are passed retaining bolts or pins 4, the bolts resting upon horizontal
plates 5 extending between the flanges 17 and 16, any upward movement of the
bolts being prevented by guiding pins 6.
The inner ends of each of the bolts are made in the form of hooks 7, as best
shown in figure 2, and the bolts are normally held forward within the ways 12 by
springs 8 that are mounted in the short posts 9 that are carried by the partitions 5,
pins 1 being arranged as usual in connection with the springs &.

page_text: In figure 4 I fully illustrate the construction of the key which it is designed to
employ in connection with the lock described, and this key is provided with as
many bits 30 as there are bolts in the lock, and, as shown, these bits are arranged
upon opposite sides of the key. The key shank is hollow, as indicated in figure 4,
in order that it may ride over or receive the key spindle 31. Just opposite the
hooks 7 of the bolts 2 the plates 15 are formed with appropiately shaped openings 34
which openings admit the bits of the key.
In operation the key is inserted through the aperture 12¹ formed in the bottom 11
so that the key spindle will enter the bore in the key shank; the key is then
turned so that its bits 30 will pass through the apertures 34 in the plates 15 and
engage with the hooks 7 of the bolts 2, and a continued motion of the key will
throw the bolts out of engagement with the apertures 35 in the bow 14 and into
the lock case against the tension of the springs 8, after which the shackle may be
withdrawn from the lock.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. The combination with a lock-case, of two plates 15, 15, carrying locking
bolts 2, said plates being formed with apertures 34 through which the bits of the
key are free to pass, substantially as described.
2. The combination with a lock of two series of bolts, independent the one
of the other, and a key formed with oppositely arranged bits, substantially as
described.
3. In a lock the combination with a case and its shackle or bow, the said bow
being formed with apertures 35, of bolts carried by plates 15 and formed with
hooks 7, springs 8, key spindle 31, and a key formed with oppositely arranged bits,
substantially as described.
4. In a lock the combination with a case and its shackle, of bolts mounted on
plates having flanges and fitted within a lock case, being held in place by rivets or
bolts 21, springs 8, guiding pins 6, and a key formed with oppositely arranged bits,
substantially as described.
