Specification of Letters Patent.

Patented May 23, 1916.

. Application filed September 18, 1914. Serial No. 862,350.

To all whom it may concern:

Be it known that I, JOHN C. J ORGENSEN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have, invented certain new and useful Improvements in Bench- Stops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a bench stop to be used upon a carpenter or pattern makers bench for holding wood being worked upon by the carpenter, and the primary object of the invention is the provision of a bench stop which will automatically adjust itself to accommodate pieces of material of various lengths.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement ofjparts as will be hereinafter more fully described, illustrated in the accompanyin drawings and claimed.

In descri ing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like or corresponding parts throughout the several views, and in which;

Figure l is a top plan view of the improved bench stop, Fig. 2 is an end view of the improved bench stop, Fig. 3 is a cross sectional view on line 3-3 of Fig. 1, Fig. 4 is a top plan view of the bench stop showing a part of the mechanism thereof removed andFig. 5 is an end view of the improved bench stop showing the end opposite to that exposed in Fig. 2 in the drawing.

Referring more particularly to the drawings, 1 designates a fragment of a surface of a carpenter or patternlmakers bench, which has two guide strips 2 and 3 mounted upon "the upper surface thereof. The guide strips 2 and 3 are braced by suitable substantially triangular shaped braces 41 and the strip 3 1s positloned obliquely to thestrip 2 as well as extending angularly upward from the surface of the bench 1 as is clearly shown in Figs. 2 and 5 of the drawings. The guldmg strips 2 and 3 are secured to a base board 5. The base 5 has a frame 6 seated thereupon which frame is positioned between the guides 2 and 3, and has its side 7 extending obliquely to the straight side 8 of the cas ing 6. The straight side 8 of the casing 6 is provided with a shoulder 9, the purpose will be hereinafter more is of considerably less wi th at the inner rear end 16 thereof than at the forward (end, as is clearly shown in the drawings, ahd'it has a pin 17 extending laterally across the interior thereof and positioned adjacent the rear narrow end thereof, which pin has one end of a contracting spiral spring 18 secured thereto as is clearly shown in Fig. 3 of the drawings. The outer end of the spiral spring 18 is secured to the head of the pin 11, and the spring 18 tends to hold the casing 6 in an outwardly extending position as is shown in Fig. 1 of the drawings, when it is released from being held under tension by the. catch member 19.

The catch 19 is pivotally mounted upon pin 20, which is carried by the rear end of the casing 6. The catch 19 has an arm 21 formed thereupon which serves as a handle for the manual manipulation of the catch. The movement of the catch 19 is limited by pins 22 and 23, which are inserted in the end of the casing 6 as clearly shown in Figs. 4 and 5 of the drawings. The forward wide end of the casing has a toothed plate 25, which plate has a transversely extending portion 26 provided with teeth 27 for engagement with a piece of wood or timber to be worked upon by a carpenter or pattern maker. The casing 6 has a removablecover plate 30 secured to the upper surface thereof, whereby access may be gained to the interior of the casing for the replacing of spring 18 when it is necessary to do so.

In the operation of the improved bench stop; when it is desired to use the stop for holding a piece of wood to be shaped, upon a working bench, the catch 19 is disengaged from the guide 3 which permits the springpiece of wood against movement upon the wood in place, as is shown in dotted lines in Fig. 1 of the drawings, during the working.

thereupon.

In reducing the invention to practice, certain minor features of construction, combination and arrangement of parts may necessitate alterations to which the patentee is I entitled provided such alterations are comprehended within the scope of what is claimed.

What is claimed is:

1. In a bench stop, a supporting base, a pair of guide bars secured to said base and extending upwardly therefrom, a casing slidably mounted between said guide bars and held against lateral movement by pins, said pins being carried-by said base plate and projecting through the bottom of said casing, a contracting spiral spring being positioned Within said casing and having one end connected thereto, the other end of said spiral spring being connected to one i of said pins for forcing said casing outwardly, and means for holding said casing in an inward position against the action of said spring.

- 2. In a bench guides secured to said base plate and extending upwardly therefrom, a pair of pins secured to said base plate and projecting vertically therethrough, a casing slidably mounted upon said base plate, said casing being provided with longitudinally extendingslots formed in the base thereof, said vertically upstanding pins being positioned in said slots for guiding the movement of said casing upon said base plate, a contracting spiral spring positioned within said casing and having one end thereof secured to the casing, the-other end of said spiral spring being secured to one of said pins, a catch pivotally connected to one end of said casing and adapted for holding said casing against movement by said spring, a

toothed plate secured to the end of said casing opposite to said catch, said casing having one side thereof cut away to form a recess for the reception of a piece of timber.

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