WORK HOLDING ATTACHMENT FOR VISES Filed Oct. 28. 1941 Patented Oct. 20, 1942 UNITED STATES PATENT OFFICE WORK HOLDING ATTACHMENT FOR VISES Edward Kochorosky, Two Rivers, Wis. Application October 28, 1941, Serial No. 416,880
3 Claims.
This invention relates to Vises and more particularly to a work-hold-down attachment therefor.
An object of this invention is to provide as a new article of manufacture a hold-down attachment for mounting on a movabl jaw of a vise for holding the work down on a flat surface, such as the top of a bench or the like.
Another object of thi invention is to provide an attachment of this kind which is simple in construction and may be applied to a vise without changing any of the present parts of th vise.
A further object of this invention is to provide an attachment of this kind which is formed with means for holding the device against movement relative to the vise and also against movement relative to the work.
With the foregoing objects and to others which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be more specifically referred to and illustrated in the accompanying drawing, wherein an embodiment of the invention is shown, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.
In the drawing:
Figure l is a detail front elevation of a work hold-down attachment for a vise constructed according to an embodiment of this invention,
Figur 2 is a detail top plan of the device, and
Figure 3 is a detail end elevation of the device in applied position with respect to a vise jaw and an article of work.
Referring to the drawing, the numeral I designates generally a movable jaw of a vise which may be associated with a bench or table I I having a fiat upper surface I2. The vise jaw ID as shown in Figure 3 is adapted to project slightly above the top surface I2 of the bench or table I I,
and the forward face I3 of the jaw I0 is disposed at right angles to the upper or horizontal face I4 thereof.
In order to provide a means whereby an article of work I5 may be held down fiat on the working surface I2 of the table II, I have provided as a new article of manufacture, a work-hold-down attachment generally designated as IS. The attachment I6 comprises an elongated flat body I! which is substantially rectangular in plan and also rectangular in end elevation. The lower face I8 0f the body I! is adapted to engage on the upper surface I4 of the jaw ID. A work holding jaw I9 is formed integral with the body I! and projects forwardly and downwardly therefrom. The jaw I9 may be of a width substantially equal to the width of the body I1, and in end elevation the jaw I9 is formed with a downwardly inclined upper fac 29 and a downwardly inclined lower face 2|. The two faces or surfaces 20 and 2| are disposed in forwardly convergent relation and terminate at their forward ends in a vertically disposed work engaging face 22.
The face 22 is serrated throughout the length and width thereof so that when the surface 22 contacts with the adjacent end of the Work I5, the jaw I9 will not slip relative to the adjacent end of the work. The jaw I9 is formed with a downwardly offset portion 23 which extends downwardly from the lower surfac I8 of the body I! thereby providing a right angularly disposed shoulder 24 which is adapted to confront and engage the vertical face I3 of the jaw ID. The rear side of the jaw I9 along the offset portion 23 thereof is formed with a pair of parallel and vertically spaced apart grooves 25 which extend inwardly from the rear vertical face 24 of the offset portion 23, thereby forming a plurality of vertically spaced ribs which are adapted to engage the vertical face I3 of the jaw I0 in order to hold the jaw I9 against vertical movement relative to the jaw I0. When the attachment I6 is in applied position, the lower or forward end of the jaw l9 will be normally disposed in upwardly spaced relation to the working surface I2 of the table I I, as shown in Figure 3. The attachment hereinbefore described may be removably mounted on the jaw I9, or if desired, may be bolted or otherwise fastened to the upper surface thereof with the offset portion 23 engaging the working ide of the jaw I0. When the jaw I0 is moved inwardly towards the adjacent end of the work I5, the jaw I9 will be tightly clamped between the jaw I0 and the adjacent end of the work I5. Since the upper edge of the work engaging face 22 of jaw I9 lies in a lower horizontal plane than the lower edge of rear face 24, a tight clamping of the jaw I9 between the jaw IO and the work I5 will effect a downward pressure on the work I5 so as to maintain the lower side of the work I5 flat upon the working surface I2 of the table or bench II. It will be understood that the other or opposite end of the work I5 may be engaged with a conventional bench stop or other abutment which may be mounted on the bench or table I I and project upwardly therefrom.
What I claim is:
1. A work hold-down attachment for a vise comprising an elongated body positionable over the upper end of a movable vise jaw, a downwardly inclined work engaging jaw integral with said body terminating in a work engaging face, the rear end of said work engaging jaw extending right angularly and downwardly from the lower surface of said body for engagement with the forward side of said movable jaw, the extended rear end of said work engaging jaw being formed with a plurality of parallel longitudinal grooves to thereby provide longitudinal ribs between the grooves for engagement with said movable jaw, said ribs holding said attachment against upward movement relative to said movable jaw, and serrations oarried by the work engaging face of said work engaging jaw, the upper edge of the work engaging face of the work engaging jaw being in a plane lower than the lower edge of the rear end of said work engaging jaw.
2. A work hold-down attachment for a vise comprising the elongated body positionable over the upper end of a movable vise jaw, a downwardly inclined work engaging jaw integral with said body terminating in a substantially vertical work engaging face, the rear end of said work engaging jaw extending right angularly and downwardly from the lower surface of said body and having a face for engagement with the forward side of said movable jaw, the extended rear end of said work engaging jaw face being formed with a plurality of parallel longitudinal grooves to thereby provide longitudinal ribs between the grooves for engagement with said movable jaw, said ribs holding said attachment against upward movement relative to said movable jaw, and serrations carried by the forward edge of said work engaging jaw, said work engaging jaw having forwardly convergent and downwardly inclined upper and lower faces, said work engaging face having its upper edge in a plane lower than the lower edge of the jaw engaging face.
3. A work hold-down attachment for a movable vise jaw comprising a downwardly and forwardly extending work engaging jaw, said latter jaw being of substantially truncated V-shape in transverse section and the forward edge of said latter jaw being substantially vertical, serrations carried by said forward edge for engagement with the work, the rear edge of said latter jaw being substantially vertical and formed with a plurality of longitudinal parallel grooves, and a supporting body integral with said latter jaw and disposed at an obtuse angle relative thereto, said body being offset upwardly from the lower side of said latter jaw and adapted to engage on the upper side of said movable jaw, said forward edge of said latter jaw having its upper edge in a plane lower than the lower edge of said rear edge of said latter jaw.
