ANDREW STRAND, OF MINNEAPOLIS, MINNESOTA.

VISE.

Application filed May 14, 1919. Serial No. 296,969.

To all whom it may concern:

Be it known that 1, ANDREW STRAND, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and useful Improvement in Vises, of which the following is a specification. 7

My invention relates to vises, which are commonly used in various shops, and is particularly adapted for use where it is desired to quickly remove the face plates from the main jaws o the vise so that other face plates can replace the same for various kinds of work. In using a vise, it is often desirable to remove the face plates of the gripping jaws of the vise so as to more conveniently hold a piece or article between the vise jaws and use different sets of faces on the gripping jaws of the vise so as to hold the article in the vise in the most convenient and practical manner, but it is an essential feature of my invention that the face plates of the gripping jaws be quickly removable and still firmly held when in place on the jaws of the vise.

It is also a feature of my invention to provide a vise with ,one of its jaws pivoted in relation to the vise proper, so that different jaws can be turned to extend at an angle to the other; jaw of the vise and a means for holding this jaw rigidly in this angular position so that an article can be clamped between the aws of the vise, while their faces are at an angle to each other and the jaw which is set at an angle being held rigid against rotation while gripping the article between the gripping jaws of the vise. This is an important feature, as it overcomes and prevents the .movement of the pivoted jaw while holding any article between the vise jaws.

The peculiar arrangement and combination of elements will be clearly set forth in the specification and claims.

In the drawing forming part of this specification:

Figure 1 is a side elevation of my vise.

Figure 2 is a plan view of the vise.

Figure 3 is a plan view of a detail of one of the jaws of the vise, a portion of which is broken away.

Figure 4 is a back view of one of the face plates of the vise.

Figure 5 is a side view of a variation of face plate used. on my v1se.

Figure 6 is a section on the line 6-6 of Figure 3.

The vise A has a stationary portion 2 and a movable portion 3, the general construction of which is common in the ordinary bench vise. The stationary portion is formed with a base portion 4, by which it is adapted to be secured in the ordinary manner to a bench, or other place where it is desired to rigidly hold the vise for use.

The portions 2 and 3 of the vise are formed with upwardly projecting main jaw portions 5 and 6, respectively, to which are remov-ably or detachably secured a pair of face or gripping plates 7. The gripping faces 8 of the plates 7 can be made serrated or roughened, or of any suitable shape to hold various articles in the vise, and in some instances, it is desirable to have the faces 8 smooth and highly polished, so as not to injure the article gripped in the vise. Each of the face plates 7 are formed with an elongated projection or tongue portion 9, which projects from the inner face 10, having curved ends 11 which terminate a short distance from the ends of the face plate, and holding pins 12 are formed projecting from the tongue 9, which are formed with a beveled end 13 and a notch 14. The pins 12 of the plate 7 are positioned near the ends of the projecting tongue 9, with the notches 14 on the inner side of each of the pins so that when the plates 7 are attached to the members 5 and 6 of the vise A, the notches 14 will be engaged by the spring operated catches or bolts 15. The catches 15 are slidably held in the passageway 16, formed in the members 5 and 6, and are resiliently held spaced. apart by the coil spring 17 The catches 15 are formed with engaging beveled ends 18, which are adapted to engage in the notches 14 and which are similar in shape to the notches 14. The body portion of the catches 15 are cut away at 19 to receive the pins 20, which hold the spring catches 15 from being forced too far apart by the c011 spring 17 when the pins 12 of the face plates are removed from the openings 21 in the members 5 and 6, the catches being limited by the shoulders 22, which engage against the pins 20 and form a stop to hold the catches 15 in place.

The pins 20 also hold. the catches from rotating in the opening 16, in this manner always causing the beveled ends 18 to engage properly with the notches 14 of the pins 12.

The faces 23 of the members 5 and 6, against which the backs 10 of the face plates engage, are formed with a recess 24 of a similar size and shape as the projecting tongue 9 on the face plate 7, so as to receive the tongue or projecting portion 9 witha close fit, to hold the same against heavy thrusts and strains when the face plates are in position on the members 5 and 6 and in use. In this manner practically no strain is transmitted to the holding pins 12 and the catches 15 from the strain on the face plates when holding a member therebetween, and thus allowing the face plates 7 to be easily removed when it is desired. The spring catches work automatically and allow the plates 7 to be snapped into place or to be quickly disengaged from the jaw members 5 and 6. The jaw members 5 and 6 are cut away with a beveled surface 25 on either end, which allows a tool, such as 26, illustrated in dotted outline in Figure 3. to be inserted between the end of the face plates 7 and the beveled edge of themembers and 6 to pry the face plates 7 free from the spring catch 15, when it is desired to, remove the same.

It is very desirable, in a machine shop or other places, to have a vise with removable face plates so that various forms of face plates can be used, but it is highly essential to have a construction whereby the face plates can be easily and quickly removed. This feature is accomplished in my invention, as the spring catches allow the face plates to be quickly and easily removed, still being held rigidly in position and under the tension of the spring 17, when the face plates are attached tothe main jaw members of the vise.

The face plate 7, illustrated in Figure 5, is formed with engaging points 27, which are cut up from the surface 8 of the plate and are for the purpose of holding a leather, rubber or fiber block, such as 28. This con struction allows a soft gripping surface to be used for delicate articles which are held in the vise A and by means of various sets or pairs of different face plates 7 the ordinary vise can be used for practically any holding purpose, the spring catch holding means being the essential feature in the use of pairs of removable face plates.

The gripping member or jaw 5 is pivotally held to the body portion 2 of the vise A by means of the semicircular shank 29, having an enlarged head 30 which is also of a semicircular shape, and the rearwardly projectmg portion 31 of the member 5 has a downwardly projecting circular shaped engaging. flange 32, which engages a similar surface in the body portion 2 of the vise and thus holds the member 5 rotatable on a comparatively large circle.

The outer surface of the flange 32 is serrated to form teeth The teeth 33 are engaged by similar teeth formed in the movable head or gripping member 34, so as to hold the member 5 against rotation, when it is desired, and to hold the same rigidly against turning in various positions, with the gripping face carried by the member 5 parallel to the gripping face carried by the member 6, or angularly to the same. 41 threaded bolt 35, which is formed with an operating head 36 on one end, and having its other end swivelly connected to the member 34, is threaded in the rear portion of the member 2 and moves the gripping head or member 34 into or out of engagement with the teeth 33 when the operating head 36 is rotated. Holes 37 are formed in the head 36, into which a suitable tool can be inserted to operate the threaded bolt 35, and thereby move the member 34 in either direction. The recess 38, in the member 2, holds the engaging head or member 34 in position in the rear portion 2 of the vise A. Aprotecting plate 39 is secured by screws 40 to the rear portion 31 of the jaw 5 and extends over the member 34 and teeth 33 to protect the same against filings, etc.

In the use of the vise A, when a member .or article such as 41, which-is angular in shape, is engaged. between the jaws 5 and G of the vise, the member 34 is disengaged from the teeth 33 to allow the jaw 5 to rotate so that its face plate 7 engages parallel with the angular surface ofthe member 41 and before the jaws of the vise A are caused to grip the member 41 tightly,

the member 34 is operated to engage the teeth 33 to rigidly hold the jaw member 5 in an angular position, as illustrated in Figure 2, whereupon the jaw members 5 and 6 can be drawn tightly against the article 41 to hold. it in the vise. It will be noted that in. gripping a member of this nature between the members 5 and 6 of a vise, especially where the member, such as 41, does not extend to the longitudinal center line, such as 42 of the vise, in a constructionwhere one of the jaws, such as 5, is ro-- tatable, unless the rotatable member 5 is rigidly gripped in the proper angularposit-ion in a relation to the member 6, by a means, such as the teeth 33 and the member 34, when the jaws 5 and 6 are drawn tightly against the member 41, the member 5 would rotate on its pivot until the points or edges 43 of the ends of the gripping plates 7, opposite to the member 41, come together. Thus, instead of holding or gripping the. member 41 flatly against two angular sides, it would be at the points 44 between the face plates 7, and would not be held rigid but would have a tendency to -move pivotally in the jaw members 5 and 6. By the engaging means at the rear of the member 6, sucii! the teeth 33 and the engaging head 34:, this is entirely overcome, and the rotatable aw 5 is rigidly held in. any angular position in relation to the member 6 or parallel thereto. This feature is highly important in my invention.

In accordancewith the patent statutes I have described the principles of operation of my invention, together with the apparatns which I now consider to represent the best embodiment thereof, but I desire to have it understood that the construction shown is only illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims:
