Description
On. WESTON, OF LOWELL, MASSACHUSETTS;
Letters Patent No. 74,182, dated February 4, 1868.
IMPROVEMENT IN BENCH-IIOOES-IOR GARPENTER'S" BNGHES y tite tlnhult maar tu yit their 3mes mimi mit nmtng'prrt nf its time.
TO ALL WHOM IT MAY QONCRN:
Be it known that I, C. H. WSTON, of Lowell, in the county Of Middlesex, and in the Sita-te of Massachusetts, have invented certain new and useful Improvementsin Ben'chfHOoks; and do hereby declare that the following is a full, clear, and exact description thereofreference being had to the accompanying drawings, and:
to the letters of reference marked thereon. l
In the annexed drawings, maliing part 4of this speciication, A. represents a metallic plate about two'inches wide, and from three'to four inches in length. This plate is let into ajcarpenter's workbench, near'one end, until its upper edge is Hush withthe `top of the bench. A suitable recess is formed in the upper side of .the-
plate, as will be set forth, andpn the under side are -cust two loops or projections, B and C. An open sliding case, G, passes into the loops B and C, and is heldin them at and against thebottom of the plate, D represents ametallic bar, which has a rim or ange on its upper end, in which are formed teeth, z x. This bar stands in evertieal position, its lower end passing `through e. hole in the plate A, made tov receive it, .andalsothrough' the ense G, which lies beneaththe plate. A spring,.E, made of coiled wire, connects the lower end of bar D to the'loop or projectiouB, and supports it, keeping it constantly pressed upward. H represents'a shaft orholt,
which is providedwitha long head, I, and which is cam-shaped on a portion of its surface below this hcud.'
This bolt passes through a hole in the plate A, and through the case Gr, its lower `end having a bearing Aiu the loop or projection C. When this bolt is in one position it lits loosely in the case G, but-when turned partially around, its cam-surface causes it to fit Vsnugly or very tightly in the case G, forcing it, slightly endwise, and securing it firmly in a fixed position.v The bolt H is turned by the head or thumb-and-inger piece I. The Object of the bar D is to hold lumber or boards in place while being pinned, and thisbar is setn any required position by turning the bolt I-I, so that it will cause the case G to draw slightly endwise, and pressing against i the bar to hold it securely in position. The spring E throws the bar D up as soon as it is freed, while said bar is held in any desired place by simply tudrning the bolt H partially around. The object of the recess in the upper side ofthe plate .is to holdV the head I, and allow the Harige on the upper en d of bar D to sink to a lcvcl with the top of the table.
The above-described device is designed as an improvement uponmy patent of October, 1866, being more economical and simple vin the construction'.
' What I claim as an improvement upon said patent, is-
The belt II, with its cam-projection', when used withtheslatted-case for clamping bar D, the several parts l being constructed and operating substantially as speced.
In testimony that I claim the foregoing, I have hereunto setmniy hand, this 9th day of November, 1867. e. H. WESTON.

GEO. A. GRIFFIN, L. N. HUNTINGTON.
