JOHN B. DADE, OF FRANKFORT, NEW YORK.

VISE.

To all whom it may concern:

Be it known that I, J oi-IN B. DADE, a citizen of the United States, residing at Frankfort, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Vises, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to a vise and I declare the following to be a full, clear, concise and exact description thereof sufficient to enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings in which like reference characters refer to like parts throughout the specification.

The object of the invention is to provide a vise that will be efficient in operation and of simple construction whereby the same may be cheaply manufactured.

The salient features of the device embody a jaw adjustably disposed relative to a slidingly mounted counter jaw which is actuated by the intermediate movement of an ec,- centric or cam controlled by a lever handle adapted to be retained in any position in its arc of movement by friction means.

Other features will appear from the drawings, in which:

Figure 1 is a side elevation of the device partially in section; Fig. 2 is a plan of the vise; Fig. 3 is a transverse section taken on the line 3 3 of Fig. 1; Fig. 4 is a transverse section taken on the line L--l of Fig. 1; Fig. 5 is an end elevation, somewhat diminished in size; Fig. 6 is a perspective view, enlarged, of a bolt employed on the device; Fig. 7 is a perspective of a plate, showing more particularly certain shoulders; Fig. 8 is a detail perspective of certain disks; Fig. 9 is a detail perspective of a sleeve; and Fig. 1() is a plan of the detail shown in Fig. 7; Fig. 11 is a plan view from beneath of Fig. 8, made to the scale of Fig. 1.

Referring more particularly to the drawings, the body of the device is preferably constructed from a metallic casting 1, having base or platform 2, laterally recessed, as at 3-3 etc. for the suitable mounting of the device upon any proper standard;

Upon opposite longitudinal sides of body 1, there are flanges 1 -4 adapted to slidingly support jaws 5 and 6 having hardened faces 7 and 8 respectively, held to said aws 5 and 6 by bolts 9, whose heads 10 are countersunk in the adjacent portion of said jaws 5 and Specification of Letters Patent.

6. Faces 7 and 8 may be replaced by new ones whenever same become worn or destroyed by use of the device. Jaw 5 is adjustably held relatively to jaw 6 by pivotally mounted rack 11 having depending member 12, recessed at 13 for the vertically adjust` able reception of the adjacent end of rack 11 upon stud or bolt 14 whose head 15 is counter sunk and remote end threaded at 16 whereby to be mounted in a correspondingly threaded bore in body 1. Said depending member 12 of rack 11 is elevated or lowered within the limits defined by recess 13 by means of set screw 17 mounted in the lower central part of .member 12. The remote portion of rack 11 has a depending member 18 recessed transversely at 19 for the reception of one end of lever 20 pivotally mountend to said member 18 by bolt or screw 21. Said lever 20 is fulcrumed upon bolt 22 supported by lugs 253-23, integral with body 1. Bracket 11 is held in elevated position whereby its teeth 24: will be normally in mesh with teeth 25 upon the under surface of jaw 5, by coiled spring 26 mounted in recess 27 of the casting or body 1. In order to lower said teeth 211 of rack 11 so as to be out of mesh with teeth 25 of aw 5, it is only necessary to pull upward upon the outer end of lever handle 20, which lever will cause rack 11 to swing downward upon bolt 1-l as a fulcrum. Said pivotally supported end is vertically adjustable by the screwing or unscrewing of set screw 17.

Obviously, from the foregoing description, jaw 5 may be moved relatively to jaw 6 whereby to adapt the vise to articles of different dimensions.

Jaw 5 is confined to sliding movement along flanges 1*4 by cleats 28-28 secured to said jaw 5 by bolts or other suitable means 29-29 and adapted to project under the lower surfaces 30-30 of fianges 1 -4.

Jaw 6 is similarly confined to flanges 1 4 by cleats 31-31 held to said jaw 6 by bolts 32-32 and is slidingly actuated to approach or recede from jaw 5 whereby to hold or release an object between jaws 5 and 6 by an eccentric mechanism now to be described.

Integral or otherwise connected with jaw 6 are two bearing brackets 33-33 between which there is pivotally mounted by pin or bolt 34, end 35 of metallic strap 36. The remote end 37 of said strap 36 embraces disk 38 having eccentrically disposed underneath the same and preferably integral therewith a disk 39 which is shouldered at 40 and 41 to correspond with

shoulders

42 and 43 of rectangular plate 44, slidingly mounted in ways or grooves 45 of body l.

Above disk 38 or on the reverse side from that on which disk 39 is disposed is a hub or sleeve 53 concentric with disk 39 but eccentric with disk 38 with which it may be integral.

Plate 44, and

disks

39, 38, and hub or sleeve 53 are held in assembled position, whereby disk 38 is eccentric to disks 39 and hub or sleeve 53 by wrist-pin 49 having rectangular shaped head projecting onk either side under shoulders 51-51 formed in body 1, and slidingly mounted in recess 52 provided in casting or body l. Said stationary adjustable plate 44 is held at any location along Ways or grooves 45 45 by means of collar 46 assembled upon wrist-pin 49 and bearing partially against shoulder 55 thereof and also against plate 44 when the parts are assembled. Said collar 46 bears against stationary adjustable washer 47 held rigidly in vertical location by nut 48 screwmounted upon wrist-pin 49.

The central portion of body l is recessed at 56.

The operation of the device is eected in the following manner, namely: Nut 48 is tightened upon wrist-pin 49 to force sleeve 46 upon plate 44 and head 50 of wrist-pin 49 in contact with shoulders 51-51, whereby to confine said wrist-pin 49 and parts assembled thereon, namely plate 44,

disks

39, 38, 37, sleeve 46, to a given position along ways or grooves 45-45, whereby said wristpin 49 may be functioned to act as a fulcrum for the longitudinal reciprocation of jaw 6, which is actuated by disk 38 eccentrically controlled by lever handle 57 keyed at 58 to l hub or sleeve 53, integral with disk 38. J aw 5 is also adjusted with reference to nearness to jaw 6 by means of teeth 25 thereon and teeth 24 of rack l1 which may be lowered from mesh with teeth 25 by pulling upward on lever handle 20. An object is held between jaws 5 and 6, whereupon the handle or lever 57 is moved from the position indicated in Fig. 5 to theposition indicated in Fig. 2, the pull being a convenient one for a right handed operator, though the parts may be reversed for a left handed operator. In order to hold said handle 57 in this last position whereby an object between jaws 5 and 6 will be firmly confined therebetween, or in other words in order to prevent handle 57 from slipping backward to its original position, the invention contemplates the employment of

shoulders

42 and 43 of plate 44 which shoulders are rounded o' at 58 and 59, so that

shoulders

40 and 41, which are likewise rounded offV at 60 and 6l will ride upon said

shoulders

42 and 43 and thereby effect a forcible contact of the said shoulders with each other, which contact will in turn hold the handle 57 rigidly in any desired locking position. This locking means is effective for the reason that any wear may beI taken up by tightening nut 48 upon wristpin 49.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. In a device of the character described, the combination with a base of two jaws each adapted to be moved and fiXed thereon, one of them having a toothed face on its lower surface, a bracket having teeth to engage with the said toothed face, the said bracket having portions depending below a fixed part of the base, a spring member acting to press the Ibracket upward from the base, means at one of the depending portions to adjust the bracket relatively to the base and lever means at the other depending portion to raise or lower the bracket, by the coperation of which means to put the teeth of the bracket into or out of contact with the toothed face of the jaw.
