EDWARD MATHIAS PETERS, OF D'HA\IS, TEXAS.
WORK-HOLDER.Specification of Letters Patent.
Patented Sept. 9, 1919.
Application filed January 17, 1918. Serial No. 212,264.
To all whom it may concern:
Be it known that I, EDWARD MATHIAS
PETERs, a citizen of Austria, residing at
D'Hanis, in the county of Medina and state
5 of Texas, have invented certain new and use-
ful Improvments in Work-Holders, of which
the following is a specification.
This invention relates to improvements in
work holders and more particularly to bolt
10 or rivet holders and its object is to provide
simple practical means for securely holding
a bolt, rivet or the like against movement
while it is being operated upon, that is filed,
threaded or shortened. With the foregoing
15 and other objects in view the invention con-
sists in the combination and arrangement
of parts to be hereinafter fully described,
pointed out in the appended claim and illus-
trated in the accompanying drawing which
20 forms a part of the specification and in
which-
Figure 1 is a top plan view of my improved
work holder applied to a work bench.
Fig. 2 is a side elevation of Fig. 1 showing
25 a rivet held thereby.
Fig. 3 is an end view on line 3-3 of Fig. 2.
Fig. 4 is a fragmentary view of a slightly
modified form of holder bar employed.
Like reference characters denote corre-
30 spending parts throughout the several views.
My improved device comprises a holder
bar the body portion 1 of which is straight
and flat and is formed with a plurality of
perforations 2 of a variety of shapes and
35 sizes to receive the shanks and necks of bolts,
rivets and the like to be operated upon. The
body portion 1 shown in Fig. 4 differs from
that shown in the other figures only in theshape and relative position of the perfora-
tions formed therein.. The body portion 1 is 40
formed with a short bent end 3 formed with
a perforation 4 and with a relatively long
bent end 5 disposed parallel to the end 3 and
formed with a relatively large perforation 6,
the said end 5 being itself formed with a 45
bend 7 and then adapted to be secured by
bolts 8 to the work bench 9.
The bolt or rivet 10 under operation is
introduced, shank first, through the perfora-
tion 2 that will snugly receive the neck por- 50
tion 11 of the bolt. When. the bolt or rivet
is in the position shown in Fig. 2 the wedge
bar 12 is introduced into the perforations 4,
5 of the bent ends 3, 5 when it will contact
with the rivet head and hold the rivet firmly 55
against the action of gravity, one perforated
portion of the body 1 of the holder bar pre-
venting rotation or play of the bolt or rivet
while it is being operated upon. When the
operation upon the bolt or rivet is completed 60
the wedge bar 12 is withdrawn and the rivet
or bolt readily removed.
What is claimed is
A work holder comprising a slotted and
perforated strap bent to form at one end a 65
slotted arm and at the other a longer slotted
arm and a foot-piece, and a removable wedge
inserted in the slots in said arms.
In testimony that I claim the foregoing as
my own I have hereto affixed my signature in 70
the presence of two subscribing witnesses.
EDWARD MATHIAS PETERS.
