Patent Number | 781 958 |
Date Applied For | 6 May 1904 |
Date Issued | 7 Feb 1905 |
Issued to | Herman A Knoke |
Location | Chicago IL |
Current Class/ subclass | 269/ 220, 236, 242 |
The illustration has 3 figures:
Oddly, the two witnesses to the drawing are the not the two witnesses to the specification.
Quoting the second and third paragraphs of the specification:
My invention relates to an improvement in the class of clamps used in carpenter and cabinet work in which the jaws are adjustably connected by a right-and-left screw passing through them near the read end of the clamp and a similar screw passing through them near their transverse centers, each screw having its bearings in a pair of shafts journaled within the jaws to extend across the screws at right angles to the latter for adapting the jaws to be set at varying relative angles without binding on the screws through the medium of which the setting is effected.
The object of my improvement is to simplify the construction of the variety of clamp referred to and to greatly increase its strength.
Patent Number | 810 543 |
Date Applied For | 1905 Jan 25 |
Date Issued | 1906 Jan 23 |
Issued to | Herman A Knoke |
Location | Chicago IL |
Current Class/ subclass | 269/ 174, 220, 221 |
The illustration has 8 figures:
The sectional nuts are identical for both screws.
Again, the two witnesses to the drawing are the not the two witnesses to the specification. However, they also witnessed the earlier drawing.
This patent refers to an earlier application for a patent, Serial Number 206, 670, filed 6 May 1904. It apparently concerns the manner of applying the screw bearings on the jaws. I have not yet obtained a copy.
Quoting the second and third paragraphs of the specification:
My invention relates to an improvement in the class of clamps used in carpenter and cabinet work, in which the jaws are adjustably connected by a screw passing through them near the rear end of the clamp and a similar screw passing though then in the opposite direction near their transverse centers, each screw having its bearings secured to the jaws to extend across the latter at right angles to them for adapting the jaws to be set at different relative positions.
My object is to provide a construction of clamp in the class thus referred to which is adapted to permit of its ready adjustment approximately to any dimensions of work to be held together thereby by throwing the screws out of engagement with their bearings on the jaws and then sliding the jaws upon the screws to effect an approximate adjustment without requiring manipulation of the crews, thus obviating the loss of time and labor by effecting an approximate adjustment of the jaws when it is required to be done by turning the screws in their bearings.
