and I 24 pivotally connects theHunit 22 to ‘the
base‘ l8. The outer leg portion b; of each of these:
units 22 is provided with spurs 25 curved in the
direction of the end of the legs, While the other
leg of each unit 22 is provided with a hood like
structure‘)?! having an inclined wall 28. Each
of these hood structures 2'! is provided with, a
struck out portion'bent downwardly to’ form a 20
guide fora coiled compressible spring 29 which‘
is interposed between the base plate l9 and the
inner‘s'ide of the hood 2?! as shown in Figure 2.

tional view of the handle portion ‘of the holder.
Figure 6 is a fragmentary side elevational view

Referring to the drawings wherein like nu
merals designate like parts, it can be seen that
numeral 5 represents a ‘hollow handle of any
35 desired shape in cross section, the upper portion
of which is ?ared as at a. The top 6 of this’ han
dle is provided with a depressed portion 1 in the
form of a trough extending inwardly from one
edge thereof. A short branch trough or depres
40 sion 8 extends off of the depression ‘I as shown
in Figure 1. The bottom of the trough ‘l is pro
vided with an elongated slot 9 through which the
rod I0 is slidable, this rod Hl‘above the slot 9
being provided with a head ll against which
45 the laterally disposed end portion l2 of the strip
spring I3 normally engages to hold the head in
operated position, this spring l3 being suitably
anchored as at I4 to one said wall of the trough ‘l.
V
The rod [0 extends downwardly in the handle
50 5 and connects to the laterally disposed lug 15
at one end of the bell crank I6 which is swing
ably mounted on the pin H.
The lower end of the handle.5 is provided
with lugs l8 which extend through openings in
55 the base plate 19 and these lugs are bent inward
10"?
so that the U-shaped member 23 will depend‘with
steel wool 30.
V
‘The retractor and 'detent for these units 22
consist of a plate 3i provided with a portion 32 30
extending through slots 33 in opposite side walls
of the handle 5. This plate 3| is provided with
an annular trough like formation 34, one Wall
of which is inclined as at 35. The edge portion
of this plate 3| beyond the trough 34 is pro
35
vided with a depending apron 35 vertically slot
ted to receive the aforementioned spurs 26.
A connector 31 having one end pivoted to the '
lower end of the bell crank It and at its other
end pivoted to the ears 3% on the portion 32 of the 40
plate 3| serves as a connecter between the plate
3! and the bell crank I6.
In order to release the pad of steel wool 30,
the spring I3 is pressed against the adjacent
side wall of the trough ‘I, thus releasing the head 45
ll permitting the rod II! to move to the left in
Figure 2. This releases the plate 3| so that it
can move upwardly and spring 29 swing the units
22 outwardly so that the pad 32 can be readily
disconnected therefrom. By leaving the holder 50
in this condition, a new pad can be engaged
against the base l9, or the holder upon the pad
by engaging the base against the pad, and sub
sequently, the head H can be moved to the
right in Figure 1 to the position shown which 56

will result in the engagement of the inclined Wall
35 against the inclined walls 28 and this Wedging
or cam action will return the unit 22 to the up
right position shown in Figure 2 with the spurs
26 embedded in the mass 30 and stretching the
same across the bottom side of the base plate l9.
While the foregoing speci?cation sets forth the
invention in speci?c terms, it is to be under
stood that numerous changes in the shape, size
10 and materials may be resorted to without de
parting from the spirit or scope of the inven
tion as claimed hereinafter.
Having thus described the invention, what is
claimed as new is:
15
1. A holder of the character described com
prising upper and lower plates, the lowermost
plate constituting a baseand the uppermost plate
having a peripheral downturned slotted ?ange,
a plurality of swingable members on the edge
20 portion of said base and positioned adjacent the
inner face of said ?ange, claw members on the
swingable members, spring means urging the
claws outwardly through the slots, cooperating
means on said uppermost plate and said mem
25 bers for retracting the claws upon the move
ment of the plates toward each other, a handle
connecting the plates for movement relative to
each other and means carried by the handle for
causing relative movement of the plates.
2. A holder of the character described com
prising upper and lower plates, the lowermost
plate constituting a base and the uppermost plate
35
having a peripheral downturned slotted ?ange, a
plurality of swingable members on the edge por
tion of said base and positioned adjacent the
inner face of said ?ange, claw members on the
swingable members, spring means urging the
claws outwardly through the slots, a handle ex
tending upwardly from the base, said uppermost
3. A holder of the character described com
prising upper and lower plates, the lowermost
plate constituting a base and the uppermost plate
having a peripheral downturned slotted ?ange, a
plurality of swingable members on the edge
portion of said base and positioned adjacent
the inner face of said ?ange, claw members on
the swingable members, spring means urging the
claws outwardly through the slots, a handle ex
tending upwardly from the base, said uppermost 10
plate being slidable on the handle and cam means
between the uppermost plate and the swingable
members for retracting the claws, said cam means
consisting of, upwardly and outwardly inclined
portions on the underside of the upper plate in 15
sliding contact with said swingable members; and
means on the handle for holding said inclined
portions of the uppermost plate in engagement
with the swingable members.

4. A holder of the character described com
prising upper and lower plates, the lowermost
plate constituting a base and the uppermost
plate having a peripheral downturned slotted
?ange, a plurality of swingable members on the
edge portion of said base and positioned adjacent 25
the inner face of said ?ange, claw members on
the swingable members, spring means urging the
claws outwardly through the slots, a handle ex
tending upwardly from the base, said upper 30
most plate being slidable on the handle and cam
means between the uppermost plate and the
swingable members for retracting the claws, said
cam means consisting of upwardly and out
wardly inclined portions on the underside of
the upper plate in sliding contact with said
swingable members, and means on the handle
for holding said inclined portions of the upper
most plate in engagement with the swingable
plate being slidable on the handle and cam means
members, said means comprising a manipulating ~
between the uppermost plate and the swingable
members for retracting the claws, said cam
means consisting of upwardly andoutwardly in
lever accessible through the upper portion of the
handle and a bell crank link connecting the lever
to the upper plate to raise and lower said plate.
clined portions on the underside of the upper
plate in sliding contact with said swingable
members,
