MINSTER, OF OGDEN, UTAH.

HORSESHOERS. FOdT-VISE.

Specification of Letters Patent.

Patented Feb. 20, 1912.

To all whom it may concern:

Be it known that I, ALBERT D. SMITH, a citizen of the United States, residing at Ogden, in the county of Veber and State of Utah, have invented new and useful Improvements in Horseshoers FootVises, of which the following is a specification.

The present invention relates to certain novel improvements in Vises.

In carrying out my invention it is my purpose to provide a vise primarily adapted for use by blacksmiths, horse-shoers, or the like, which is of an extremely simple construction, which employs only a single spring, and which is provided with means for locking the jaws of the vise, when desired.

With the above objects in view, and others which will appear as the nature of the invention is more fully disclosed, the improvement resides in the novel construction of elements and their arrangement in operative combination, as will hereinafter be fully described and claimed.

In the drawings, accompanying this specification, there has been illustrated a simple and preferred embodiment of the improvement, and in which drawings,

Figure 1 is a perspective view of my improved vise. Fig. 2 is an enlarged detail sectional view illustrating the jaw holding mechanism for the vise.

Referring now to the drawings in detail, the numeral 1 designates a suitable standard, the said standard having its lower portion bifurcated as at 2, and the members provided by the said bifurcations are formed with oppositely extending feet 3, the same having openings adapted to receive suitable securing elements whereby the vise is retained upon the floor of the work shop. The upper extremity of the standard 1 is enlarged and arranged at an angle to the said standard to'provide the jaw 4. This jaw at has its inner face serrated, and is adapted to coact with the swinging jaw 5 of the vise. The standard 1 is approximately centrally formed with a lateral arm 6, and the swinging jaw 5 is likewise formed with an int-urned portion 7 both the portions 6 and 7 being formed with registering openings for the reception of a pivot 8, whereby the stationary and pivoted jaws are connected together. The lower extremity of the swinging or pivoted jaw 5 is provided with a suitable opening, the said opening adapted The numeral 12 designates a link which is pivotally connected between the arms of the U-shaped lever 9 to a pin 13 which passes through suitable openings provided by the standard 1 adjacent its bifurcation 2. The link 12 extends between the arms provided by the U-shaped member and within the bifurcation 2 of the standard 1.

Secured toone side of the standard 1 through the medium of suitable detachable elements 14 is a rack bar 15. This rack bar is preferably spaced a suitable distance away from the side of the standard, and the said bar is surrounded by a sleeve 15 carried upon a substantially L-shaped member 16, the same being provided with an opening at the juncture of its arms which is adapted to receive a suitable pintle 17, and whereby the said member is pivotally connected between the arms of the U-shaped lever 9. One of the arms of the L-shaped member 16, and that which is attached to the sleeve 15 is provided with an off-set portion forming a tooth 18, the said tooth being arranged adjacent to the tooth of the bar 15. The opposite arm of the L-shaped member 16 is provided with an enlarged extremity 19, the same serving as a weight for the said L- shaped member to normally sustain its tooth 18 out of engagement with the tooth of the rack bar 15, as well as providing means whereby a link 20 is pivotally connected with the said L-shaped member. This link 20 is also pivotally connected with a locking foot lever 21, the same being pivotally connected between the arms provided by the lever 19, as at 22, and the tread 23 of the said locking lever is serrated and projects a suitable distance above the lever 9, but terminates a distance away from the connecting portion or end of said U-shaped lever 9. By this arrangement the foot of the operator may be applied to the extremity of the lever 9 without contacting with the tread 23 of the locking lever 21, but it is obvious that when material is to be retained between the jaws 1 and 5, it is merely necessary for the operator to advance his foot to bring the same into contact with the tread 23 of the locking lever 21 which, under the weight of the operator will swing the L-shaped member upon its pivot 17 so as to force its tooth 18 into engagement with one of the teeth of the rack bar 15 when the jaws may be sustained in a closed position upon the object engaged.

Briefly stated, the operation of the device is as follows: The spring 11 exerting a tension between the pintles 8 and 10 sustains the aw 5 at a distance away from the aw 4L, and causes the link 12 to assume an inclination, as well as the lever 9 to be inclined as illustrated in Fig. 1 of the drawings. A pressure exerted upon the extremity of the lever 9 will have a tendency to force the lever 9 inwardly, or toward the jaw 5, which action forces the link 12 to a greater inclination from the vertical and also swings the jaw 5 against the jaw 4. When the pressure is released, the elements will return to their initial position. When the jaw 5 is to be locked, the operator exerts pressure upon the tread 23 of the lever 21, which not only operates the L-shaped member 16, through the medium of the link 20 but also swings the tooth of the said L-shaped member into engagement with one of the teeth of the rack bar 15. The lever 9 is also tilted upon its link 12, and the tension of the spring 11 will retain the tooth 18 in engagement with one of the teeth of the bar 15. When the tooth 18 is to be released, a further outward pressure upon the lever 9 will swing the link 12 to its normal position and cause the spring 11 to spread the jaw 5 away from the jaw 4E and as a consequence permit the weighted portion 19 of the L-shaped member 14 to swing the tooth 18 out of engagement with the engaged tooth of the bar 15. The standard 1 may, and preferably is provided with a receiving box 24, the latter being attached to the said standard in any desired or preferred manner, and the said box is adapted to contain tools or devices to be clamped between the jaws 4; and 5 to be operated upon by the mechanic.

Having thus fully described the said invention, what I claim is 1. In combination with a standard having a fixed jaw and a coacting pivoted jaw, of a foot lever connected to the pivoted jaw, a link pivoted to the standard and the lever, and a spring having one of its ends connected with the lever between the link and the pivoted jaw, and its opposite end connected to the standard.

2. In a device for the purpose set forth a standard having one of its extremities enlarged to provide a jaw, a second jaw centrally pivoted to the standard, a substantially U-shaped lever straddling the stand ard and having its arms pivotally connected with the second jaw, a link pivotally connected with the lever and with the standard, a spring arranged between the standard and the lever and adapted to normally sustain the second jaw away from the jaw of the standard, a rack bar upon the standard, a toothed member pivotally connected with the lever and adapted to engage the teeth of the said rack bar, a pedal member pivoted between the arms of the U-shaped lever, and a link connection between the toothed member and the pedal member substantially as and for the purpose set forth.

3. In a device for the purpose set forth, the combination with a standard having its upper end offset and enlarged to provide a jaw, the said standard being centrally formed with a lateral arm, a movable jaw, said jaw having its central portion formed with an extension, a pivotal connection between the extension of the said jaw and the extension of the standard, an elongated U-shaped lever having its arms arranged adjacent to the opposite sides of the standard, the arms of the said lever being pivotally connected with the extremity of the pivoted jaw, a spring exerting tension between the lever and the extension of the standard, a link pivotally connected with the lever and with the standard, a rack bar for the standard, a sleeve surrounding the rack bar, an L-shaped member having one of its arms pivotally connected with the sleeve, the said arm of the L-shaped member being formed with a tooth arranged adjacent to the teeth of the rack bar, the said Lshaped member being pivotally connected between the arms of the lever, the second arm of the L-shaped member being enlarged or weighted, a link pivotally connected with the enlargement, and a locking lever pivotally connected between the arms of the first named lever and with the link, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
