4 Claims.
Serial No. 669,108
(Granted under the act of March 3, 1833, as amended April 30, 1928; 376 0. G. 757) This invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to r me of any royalty thereon.
This invention generically relates to a bench dog or stop adapted to be secured to a carpenters work bench for the purpose of retaining the work against undesirable movement; more particularly it is directed to a bench stop which is simple in construction, inexpensive to produce and which may be quickly placed in operative position and conveniently moved to and secured in the desired elevation.
Another object of this invention is to produce an assembly of the character designated having a vertically adjustable stop adapted to be raised or lowered through a series of positions and retained in any one of such positions by means of a cam mechanism, the latter being controlled through the instrumentality of a reciprocatory slide.
Other objects of this invention are to provide a bench stop assembly wherein the adjustable stop is suitably reinforced to withstand the work impacts which it quite frequently receives; to provide a stop which when not in use oiiers no projecting parts to interfere with the normal utilization of the bench, and to produce a device embodying but three major components, all oi which may be stamped from sheet metal and operatively assembled with a minimum expenditure of time, labor and material.
With these and other objects in view, my invention consists in certain novel details of construction, combinations and arrangement of parts to be more particularly hereinafter set for th and claimed.
Referring to the accompanying drawing, in which corresponding parts are indicated by similar reference characters:
Fig. l is a fragmentary perspective illustrating my improved bench stop assembly secured to one end of a carpenters work bench;
Fig. 2 is a transverse vertical section taken on line 2 2 of Fig. l;
Fig. 3 is a rear elevation oi the bench stop assembly; and
Fig. l is a bottom plan View with stop removed.
Briefly stated, this invention comprises a bracket adapted to be secured to a carpenters work bench, a vertically disposed stop slidably mounted in the bracket and means for sliding said stop to and securing it in a predetermined pesition, said means including a reciprocatory slide and interacting camming means carried by the slide and stop.
In the illustrated embodiment characterizing this invention, there is shown a portion of a carpenters work bench or table (A) to one end of which there has been secured a bench stop assembly (B) which constitutes the subject matter of this application. In its essentials this assembly consists of a bracket (C), a vertically adjustable top (D) slidably mounted in the bracket, a horizontally supported reciprocatory slide (E) mounted in the bracket and interacting camming means (F) carried by stop (D) and slide (E) to enable the stop to be moved to and secured in any desired position by reciprocation of the slide.
Coming now to a detail construction of the preceding assembly in the order of its components, bracket (C) consists of a metal strip shaped to provide front, side and anchoring sections (l), (2) and (3) respectively, as clearly shown 1n Fig. 1 of the drawing. In the course of this shaping process, front section (1) of the bracket (C) is centrally formed with a vertically extending slot (4) and provided with parallel guide flanges (5); tongues (6) are struck from side sections (2) and extended inwardly toward each other to produce guideway (6'), and sections (3) are perforated as at apertures (7) for the passage of the fastening elements (8).
Bracket (C), having been constructed as stated, is now ready to receive the stop (D) which consists of a single piece of metal of the required thickness, stamped to produce a shank (9) having horizontally extending teeth (10) formed at its upper end. To assemble the bracket (C) and the stop (D) the shank (9) of the latter is disposed to the rear of section (1) and between sections (2) of the bracket, with the free end of the shank projecting through the guide (6') formed by the inwardly projecting tongues (6) as clearly shown in Fig. 4 of the drawing.
To complete the assembly of major components the reciprocatory slide (E) is disposed between anges (5) and bracket (C) as clearly shown in Figs. 1 and 2 of the drawing. This slide (E) consists of a single piece of metal formed at its extremities with wing pieces (13) and diagonally slotted as at (12) for a purpose hereinafter to appear.
Reciprocatory slide (E) and stop (D) are operatively associated by means of a cam mechanism (F) including slot (12) and rivet-shaped follower (la) adapted to operate in said slot. The shank of the follower (14) extends through slots (l2) and (4) of slide (E) and bracket (C) respectively, and into the opening (15) centrally formed in stop (D). The free end of cui shank (14) is riveted in opening (15) and lies iiush with the outer surface of stop (D) as clearly shown in Figs. 2 and 3 of the drawing.
With the various parts assembled and interconnected as stated it is evident operation of slide (E) in one direction causes follower (14) to ascend slot (12) thus elevating stop (D), while movement of slide (E) in the opposite direction causes the follower (14) to descend slot (12) to lower the stop (D) as will be understood without further discussion. In this connection it is to be noted that Wherever follower (14) stops in the path of its travel, stop (D) will be rrnly locked in position.
In conclusion, it will be seen this invention provides a stop assembly constructed so that it may be conveniently operated with one hand, thus leaving the other free for adjustment of the work or other purposes, and furnishes a three point system of reinforcement (including tongues (6) and cam follower (14)), which will enable stop (D) to readily withstand the impacts of the work as the latter is being planed or otherwise treated.
Having described my invention, what I claim as new and wish to secure by Letters Patent is:
1. A bench stop comprising a bracket adapted to be secured to the edge of a work bench, said bracket including a longitudinally slotted front section, adog mounted on and adjustable over one surface of the front section, a diagonally slotted slide disposed upon and movable over the opposite surface of the front section, the movement of said slide being at right angles to that of the dog, and a lug projecting from the central portion of said dog and extending through the slots in said front section and slide, whereby movement of the latter will effect adjustment of the dog to any desired position.
2. A bench stop comprising a bracket adapted to be secured to the edge of a work bench, said bracket including a longitudinally slotted front section, a dog mounted on and adjustable over one surface of said front section, means for reinforcing and guiding the dog during the course of its movement, a diagonally slotted slide disposed upon and movable over the opposite surface of the front section, the movement of the slide being at right angles to that of the dog, and a lug projecting from the central portion of said dog and extending through the slots in said front section and slide, whereby movement of the latter will effect adjustment of the dog to any desired position.
3. A bench stop comprising a bracket adapted to be secured to the edge of a work bench, said bracket including a longitudinally slotted front section, parallel laterally spaced guides extending across the outer surface or" said front section, a diagonally slotted slide mounted for reciproeating movement between said guides, a dog mounted on and movable over the inner surface of said front section, the movement of the dog being at right angles to that of the slide, means for reinforcing and guiding the dog during the course of its movement, and a lug projecting from the central portion of said dog and extending through the slots in said front section and slide, whereby movement or the latter will effect adjustment of the dog to any desired position.
4. A bench stop comprising a bracket adapted to be secured to the edge of a work bench, said bracket including parallel side sections and a longitudinally slotted front section, parallel guides on the outer surface of said front section, a diagonally slotted slide mounted for reciprocating movement between said guides, a dog mounted on and movable over the opposite surface of the front section, the movement of the dog being at right angles to that of the slide, tongues struck from the lower edges of the side sections and coacting with the front section to guide and reinforce said dog during the course of its movement, and a lug projecting from the central portion of said dog and extending through the slots in said front section and slide, whereby movement of the latter will effect adjustment of the dog to any desired position.
