The Schedule referrec to in these ALettere P aten't and making prtof they same o Be it known that I, Gamen .Mmmm-, f Trjenl;

'ton,.in the -cou'nty of Mercer and State of New'Jer- 'I sey, have invented a newjfand ifsefullrnprovement in I' Parallel Viso and I' do herebyfdeclare that thefoli" lowing is a' l,.'clear', and exact description thereof, which will enable others skilled inthe art to make .and use tlie'saine, referencebeng had to the accompanying'- drawing `forming part of .this specification.

This'invent-ion relatos to new aud useful improve# ments in 'vises with parallelijaws, whereby they. are made stronger and more durable and useful than sucli ifiscs have hithertolbeen; and

It consists in the constructionfand arrangement hereinafter described."

` In the accompanying dnawing'- Q Figure 3 is a rear-end View.

Figure 4 is avertical crossf'sectionot' the vise on thefline :c x-of iigul.

Similar letters of vreference indicate correspondingl parte Y Alis the bed-plate'oi' the vise. B is the stationary jaw, which 'is a portion of or fast Bf. is the movable jaw. v

C is-the screw,'which, by means ofthe collars there-` on, (near its heath); is confined in the base orshank of the movable jaw B', but is allowed to revolve freely.

D is the nut-tube, whiciris removably connected with' the `base or shank of the stationary jaw B. The screw-thread is formed in the tube by either cutting vor brazing, V.and the tube is screwed into the Vbase or 1'- The back ends of tljelbars' lare connected together 'by the plate J, which is screwed' on afterthe bars arel in place, and which'acts as a 'stop against the base of the stationary jaw; to limit the forward movement of the front jaw.

' f By this mode of construction, the movable jaw is kept parallel witlithev stationary jaw, while the ,viseis' greatly strengthened bythe'two slidingbars.

Having thus described myinventiom4 y I 'claim' as new andA desire to secure by 'Letters A The arrangement of pal-ts, substantially as herein described, consisting, essentially, of the attachment of' the stationaryjaw torthe bed-plate A, and of the movable jaw to the parallel jaws B, the groovesgand'f 'h in the stationary jaw 'ancl bed-plate, for the support and4 guidance of .bars E, the connectingplate J, the movable nut D, and the screw C. .Y p
