Filed May 17, 1929 :Patented June 23, 1931 PATENT OFFICE PAUL IBROCKHAUS, JR., OF OESTERAU IN WESTPI-IALIA, GERMANY VISE Application led May 17, 1929, Serial No. 363,827, and in lBelgium August 25, 1928.

lMypresent invention relates lto vises and has for its object to provide a vise of a considerably simpler and cheaper construction than has been possible hitherto. This end I 'il attainfby the use of a base-plate furnished with two guide-rails, of which each is providedwith an approximately U-shaped lateral channel with oppositely arranged guide* surfaces for the slip-faces of pendent guidecheeks of the vise-jaws. f These guide-cheeks are on account of their novel attachment to.

the jaws to acertain degree resilient and thus adaptedk to automatically `accomplish their re'adjustment on Vthe worn guide-surfaces. But when the limit of this resilience has been reached the pendent guide-cheeks of the jaws are drawn inwards lfor a mechanical adjustment by means of adjusting-screws lrotatably seated in said guide-cheeks and screwed into rectangular guide-blocks slidablyarranged in slots of said guide-rails. Simultaneously herewith these guide-blocks serve to limit the ioutward movement of the vise-jaws when they strike against the closed ends of said slots.

My invention is applicable as well to vlses with a fixed and a movable jaw as to vises with two movable jaws, i. e. to the so-called machine-vises. arranged guide-rails a spindle provided with a right-hand and a lettehand screw-thread is arranged to move said jaws always simultaneously Y inv opposite directions, whereby said spindle passes through the pendent nuts of both jaws and is held against axial displacement by a xedarched abutment, which straddles said spindle between two collars of the latter.

A vise constructed in accordance with my present invention is shown by way of ex'- `ample in the accompanying drawings, in

which Figure 1 is a longitudinal section taken on `line 1--1 of Figure 2.

Figure 2 is a plan-view of the improved vise. l Figure 3 is a cross-sectional view taken on line 3 3 of Figure 1, and

Figure 4 is a similar view taken on line 4-4 of the same figure.


Between the two vertically j The frame of the vise chiefly consists of a base-plate 1 whereon two guide-rails 2 are arranged parallel to each other and integrally connected to said base-plate. These rails are also connected with each other by cross-bars 3 and an intermediate vertical wall 4. Each rail 2 is on its outer face provided with an approximately U-shaped lateral -channel 2 with oppositely arranged guide-surfaces 5, which may bearranged parallel to each other G0 but preferably converge inwardly, i. e. transversely of said channels, and are carefully machined to serve as guide-ways for the visejaws 6, of which each is provided with pendent guidecheelrs 7. These guide-cheeks solely c5 bear on said guide-surfaces 5 to leave gaps or air-spaces 8 between the under-sides of the vise-jaws 6 and the webs and top-portions of the rails 2, as clearly shown in Figures 3 and 4. The inclined guide-surfaces 5 thus ob- 70 tained are designed to reduce the' friction between them and the slip-faces ot the pendent guide-cheeks. Simultaneously herewith the pen dent guide-cheeks 7 are made resilient by the aid of the reduced web-like neclsl connected with the under-side of the jaws, by means of which 'said pendent cheeks are enabled to take up wear to a certain degree quite automatically. When, however, the wear has reached a certainlimit the adjustment is regulated mechanically by means of adjusting-screws 9, which are rotatably seated in said guide-cheeks 7 and screwed into internally threaded guide-blocks 10 seated in slots 11 of the rails 2- and protected against S5 filings and dirt by shoulders 2 ofthe guiderails 2, as indicated in Figures 3 and 4. The adjustment thus obtainable can be conveniently executed on account of the exposed position'of the headset the adjusting-screws 9 90 and may be applied to either ot the guidecheeks of each jaw 6 alone or to both jaws simultaneously.

The movement of the vise-jaws 6 to and from each other is accomplished by means of a spindle '12 provided with a right-hand and a left-hand screw-thread, which engage the pendent nuts 13 of said jaws. These nuts are itted into said jaws and retained therein in their proper positions by screws 14. The

V'spindle V12 is sustained at 4t in said inter- Y `mediate wall 4: and besides this is straddled Y by an arched abutment 15 which enters between the collars 16 and 17 integrally connected with said spindle. To prevent an axial displacement of the spindle said arched abutment is inserted into vertical slots 18 of the rails V2 and held in placethereinby screws 19, as clearly shownin Figure 3.

Cover-plates 2O andQO are attachedto the jaws 6, of `whicliplates the cover-plates-ZU cooperate with a plate 21 secured to the Y Atop of the arched abutment 15 to form a cover of variable length, which at all times forms. an eiiective meansfor the exclusion of lilings and dirt'froni tliespindle-12- v The yimproved vise is of an exceptionally small kheight .and of a very simple construction and can on these accounts be'manufa'ctured at a lowercost'than thel known, inostf' ly rather complicated vises of: this class. "1n

operationthis new vise is reliable since the inclined guide-surfaces of the guide-rails and ,the slipfacesl of thev resilient'guide-cheels I of the jaws coact under` the -inost'iavorable Y said guide-rails,`pendent guiderheeks ar'- guide surfaces, pendent nutsseatedin said of-fthe latter."
