WOODWORKIIIIG-CLAMP.
Specification of Letters Patent.
] Patented March 27, 1906.
Applioation'filed November 14, 1905' Serial No.- 287,293.
The object of the invention is to roduce adevice improved with respect to t e extension of the beam and with respect to the adjustment of the foot-block.
I In the accompanying drawings, Figure '1 is aside view with the beam retracted. Fig. 2 is a similarview with the beam extended. Fig. 3 is a top or frontview. Fig. 4 is a cross-section on the line 4 4 of the other figures.
The beam is composed of two spaced side I pieces 6, between which is a sliding or extensible piece 7. The side pieces are united at the head by the head-block, 8 the projecting e 5 part of which has a clamping-screw 9. The
respective pieces forming the beam are notchedon their rear edges, as at 10, to re-' ceive'the U-shaped latch or locking-bail 11,
which is pivoted at its ends to the adjustable foot-block 12. Pivoted to one arm of the latch 11 is a catch 13 which consists of a flat spring having a projection engageable in one of the notches of one of the side pieces 6. The foot-block 12 carries a similar catch 15, 3 5 which; is ivoted-in a recess 16 in the side of said bloc and is arranged to engage in one of the notches 10 of the middle or extension piece 7 when said foot-block is slid down on that piece, as shown in Fig. 2. The ur ose of these catches is to prevent the b I from jumping or lifting out of place.
At its head or inner end the sliding piece 7 in -guides for the sliding piece 7.
has metal pieces 17 set flush in the sides thereof, and these pieces have projecting studs 18, which are enga cable in the notches in the side bars 6. At t e foot the side bars are connected by straps 19, which serve to space said bars apart and also to form retainn use the beam is extended by disengag- 5o ing the lugs 18 from the notches 10 by giving the middle piece 7 a slight backward break or movement, allowing said piece to be slid in or out to the desired extent, after which the lugs are again en aged in the appropriate notches in the fixe side pieces. Further adjustment of the foot-block 12 can then be made by setting its latch at the desired .notch. When the latch is set on the main beam, it engages the notches of all the'pieces; I
but when it is set on the extended beam it engages the middle piece only. In the former instance the catch 13 is used to lock the block against unintentional movement. In the latter case the latch 15 is used. When these catches are engaged, the block cannot turn or get out of position, even though the clam be inverted.
at I claim as new, and desire to secure by Letters Patent, is
A clamp comprising a beam formed of notched side pieces and a notched extensible middle piece therebetween having lugs engageable in the notches of the side pieces, a head-block mounted on the side pieces, and an adjustable foot-block having a latch en- 'gageable in the notches on said pieces.
In testimony whereof I have signed my name to this specification in the presence of two-subscribing witnesses.
