IMPROVEMENT IN CARPENTERS BENCHES.

Specificationforming part of Letters Patent No. 58,858, dated October 16, 1866.

To all whom it may concern:

Be it known that 1, ROBERT MoOoNNnLL, of Lawrenceville, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Carpenters Benches and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference beinghad tothe accompanyingdrawings, forming part of this specification, in which- Figure 1 is a vertical cross-section of my improved ca-rpenters bench. Fig. 2 is a detail view, partly in section through the line 00 m, Fig. 1. Fig. 3 is detail sectional view taken through the line 3 y, Fig. 2.

Similar letters of reference indicate like parts.

My invention has for its object to furnish an improved carpenters bench, the vise of which is so constructed and arranged that the jaw can be adjusted and the article to be held secured between the jaw and the bench instantaneously; and it consists, first, in the double inclined planes for securing the article in the vise after the jaw has been set at the proper distance, in combination with handle, the upper slide, and thejaw of the vise; second, in the boxes and inclosed movable catches by which the slides are held in proper position, in combination with the slides, operating-bar, treadle, spring, and frame of the table; third, in the combination of the vertical connectingbar with the slides, for the purpose of keeping the jaw of the vise always in a vertical position.

A is the frame, and B the top, of the bench. O are boxes set into the frame A of the bench, as shown in Fig. 1, and firmly secfired in place. Through the boxes 0 are formed holes corresponding to the shape of the slides D and E,

which pass through them. The outer end of the lower slide, E, is attached to the lower end of the jaw F in such a way as to allow the said jaw to have a slight rolling motion, to enable it to adapt itself to the form of the article to be held. The upper slide, D, passes through a hole in the upper part of the jaw F.

To the outer side of the jaw F is attached theinner part, G, of the double inclined planes. This part G has a hole through it for the passage of the slide D, and is secured to the outer side of the said jaw F. His the other part of the double inclined planes. This partrevolves upon a neck formed upon the end of the slide D, and has two projecting ears formed upon it, through which is passed the bar of the handle I. This bar has knobs or handles formed upon its ends to prevent it from slipping from its place, and to make it more convenient to be operated.

When the part H of the double inclined planes is turned into the position shown in Fig. 1, the top or upper end of the jaw F is forced forward, as shown, securing the article between the said jaw and the side of the bench. The jaw F is forced back into a vertical position as soon as the part H is turned back by the spring J, one end of which is secured to the slide D, and the other end to the frame A, as shown in Fig. 1. The sides of the slides D and E are toothed, as shown in the drawings, the teeth on the upper slide pointing outward, to keep the slide from being drawn out when the vise is tightened. The teeth on the lower slide point inward, to prevent the jaw F from being pushed out toward the bench before being released, in the manner hereinafter described.

The slides D and E are held in place by the catches K and L, upon the under sides of which are formed teeth, which fit into the teeth of the slides D and E, as shown in Figs. 1 and 3. These catches are pivoted at their upper edges to the sides of the box G, as seen in Fig. 1. The inner ones of these pivoting-arms extend through the sides of the said boxes (J, and is bent at right angles, so as to form arms or levers 7c and l for operating the catches K and L.

M is a treadle, which is pivoted to the side of the frame A, as shown in Fig. 2, and to the end of which is pivoted the lower end of the bar N. This bar is attached to the side of the frame A by screws or bolts passing through slots in said bar, as shown in Figs. 1 and 2, so as to allow the bar N a vertical movement as it is operated by the treadle M. Upon the side of this bar are formed loops or eyes a and a through which pass the ends of the arms 7c and I, so that as the bar N is raised by the action of the treadle M the catches K and L will be lifted away from the slides D and E, and the jawF be left free to be moved outward or inward, as may be required.

0 is a spring, one end of which is attachedto the frame A, and the other to the end of the treadle. This spring draws down the bar N and holds the catches K and L in contact with the slides D and E, except when raised by the action of the treadle M.

I? is a bar, connecting the inner ends of the slides D and E, so that when the said slides are drawn out or pushed in the jaw F may always move parallel to the sides of the bench. The upper end of the barP is slotted, and the end of the slide D is passed through this slot and secured in place by a pin, (1, as shown in Fig. 1. The lower end of the bar P is passed through a slot formed in the end of the slide E, so that the slides D and E are compelled to move together when operated.

I claim as new and desire to secure by Letters Patent- 1. The bench-vise consisting of the toothed slides D E, jaws F, double-inclined parts G and H, spring J armed catches K L, and bar P, arranged and operating substantially as described, for the purpose specified.

2. Holding the toothed slides by means of the toothed catches K L, provided with arms la 1, operating substantially as described, for the purpose specified.

ROBERT MGCONNELL.
