FLUID-ACTUATED VISE.
Specification of Letters Patent.
Patented s in 14, 1908.
Application filed. March 1, 160%. Serial No. 196,102.
To all whom it may concern:
Be it known that 1,,THOMAS F. WARWICK, a citizen of the United States, and a resident of Metter, Georgia, have invented certain Improvements in Fluid-Actuated Vises, of which the following is a specification.
The object of my invention is to provide a r uick-acting and powerful vise operated by mid pressure, whereby the hands of the workman are left free to manipulate the work, no manual operation of the movable j aw of the vise being required. In the accompanying drawing: Figure 1 IS a view, partly in side elevation and partly in section of a fluidressure-actuated vise constructed in accordance with my invention'. Fig. 2, is a front view of the same: Fig. 3, is a rear View; Figs. 4 and 5, are views illustrating two forms of the vise; Figs. 6 and 7, are enlarged sectional views of a valve forming part of the operating mechanism of the vise; and Figs. 8 and 9, are views of a modified form of valve.
In the drawing, 1 represents the fixed aw ofthe vise which is securedto or forms part of a structure 2, table or bench, the means of attachment shown in the present instance being a bar 3, which crosses a gap in the bench 4' and also has secured to'it a cylinder structure 5, rovided with a piston 6, having a rod 7, which projects through the rear head of the cylinder and is attached to the depending rear end shank 8 ofthe movable jaw 9 of the vise, said stem or shank 8 being suitably guided longitudinally in the structure 2 vwhich carriesthe fixed jaw 1 of the vise, so
that it is free to move said structure.
Outward movement of the nrovablejaw 9 effected by means of a coiled spring 10, which is contained within a'pocket 11 on the rear head of the cylinder andacts upon the forward face of the piston 6 to force the same forwardly in said cylinder, such outward movement being restricted, either by contact ofthe piston 6 with the front head of the cylinder or by contact with the structure 2 of a gage block 12, which is adjustably mounted on the stem 8 of the movable jaw 9 and can be secured in any position of longiback and forth through tudinal adjustment thereon by. means of a clamp screw 13, hence, by a proper adjustment of this gage block, the stoppage of the outward movement of the jaw 9 can be effected at any desired point when said suitably secured tothe work-- movement is less than the full stroke of the piston 6. j
A pipe 14 communicates with any available supply of air, water, gas, or other fluid under pressure, said pipe being provided with a regu of fluid through the same can be rea erned in accordance with the desired of pressure which it is intended to exert by the movable jaw of the vise. I
The pi e 14 communicates with the chest 16 of a t rec-way valve, whose stem is )10- vided with a two-armed lever 17, the ends of which are intended to'be connected to a suitable treadle or treadles so that the valve may be turned by the pressure of the foot to either of its two extreme positions.
When in the position shown in Fig. 6, the valve opens communication between the pi e 14 and a branch 18 extending through the forward. head of the cylinder 5, and, when in its other position, shown in Fig. 7, the valve opens communication between the pipe 1.8 and a branch 19 which extends to and through the rear head of the cylinder. Said rear head of the cylinder is also provided withv an outlet pipe 20 having a valve 21 whereby the area of escape from said rear end of the cylinder can be readily regulated.
In Figs. 4 and I have not shown the valved pipes in connection with the cylinder 5, but it should be understood that said cylinder is ily govamount .intended to be equipped with the sanie arrangement of der shown in igs. 1, 2 and 3.
The normal position of the'parts iswith the movable jaw of the vise open and the pisipes and valves as the cylin-- ton 6 forced. forwardly in the cylinder 5 by the action of the s of the chest 16-is a justed so as to open comring 10, but if the valve munication between the ipes 14 and 18, as shown in Fig. 6, fluid unr er pressure will .enter the'forward end of the cylinder5and will force the piston 6 rearwardly therein so as to move the jaw 9 of the vise towards the fixed jaw 1 and clamp the work between them, the
s eed of closing movement of the jaw being d termined partly by the resistance offered to the rearward movement of the piston .6 b the spring 10, and partly to the freedom of escape of the air from the rear end of the cylinder 5 through the valved pipe 20, hence, by the properadjustment of this valve, the speed of closing movement of the jaw 9 can be accurately governed.
When the valve in the chest 16 is moved ating valve whereby the ressurev able jaw 9 of the vise, this movement being a.
uick movement since it is not restricted by t e rate of flow through the valved pipe 20. If the ower exerted by the piston of the power cy inder 5 is not suflicient to impart the desired pressure to the work heldbetween the jaws of the vise a power-multiplying lever,'such, for instance, as shown at 22 in Fig. 4 may be insertedbetween the piston rod'7 and the movable jaw 9, or, in case the stroke of the power cylinder is less than the desired opening movement of the movable jaw of the vise, a lever, such for instance as shown at 23-in Fig..' 5', may be' inserted between the piston rod 7 and themovable jaw of the vise for thus increasing the movement of the latter.
Many modifications of the vise may be devised within the scope of-my invention, for instance, the movable jaw of the vise may be 0 ened by means of a spring acting upon the s ding stem or shank of the same, as shown for instance at 10 in'Fig. 4, or the iston 6 of the power cylinder may be moved )y fluid pressure in both directions, either end of the cylinder. being open to exhaust when the other end is open to ress'ure. Such result can be effected by t e use of a four-way valve, such as shown in Figs. 8 and 9, fiu1d being directed from the pipe '14-to the pipe 18 and from the pipe 19 to the exhaust pipe 24 when the valve is in the position shown-1n Fig. 8, and fluid being'directed from the pi e 14 to the pipe 19 and from the pipe 18 to t e exhaust pipe when the valve is in the position shown in Fig. 9.
' Having thus described my invention, 1
claim and desire to secure b Letters Patent 1. The combination of t e fixed jaw strudture of the vise, a movable j'aw structure having a stem or shank horizontally slidable through the fixed jaw structure and guided so as to be incapable of turning therein, and a power cylinder connected to the fixed jaw structure and located directly beneath the samewith its axis substantially parallel to senses the line of movement of the slidable jaw, said cylinder having a piston and a piston rod operatively connected to said stem or shank of the movable jaw, substantially as specified.
2. The combination of the fixed jaw structure of the vise, a movable jaw structure having a non-rotatable stem or shank horizontally slidable through an 0 ening in the fixed jaw structure, a power cy der located directly beneath the fixed jaw of the vise and having a piston and piston rod, with a lever connected to transmit the movement of the said piston rod to the rigidly guided stem of the movable jaw of the vise, and a spring attached to the rear partof the fixed jaw structure and to that part of the stem or shank which projects to the rear of said fixed jaw structure so as to tend to open the vise, substantially as specified.
3. The combination of the fixed and movable jaws of the vise, a power cylinder having a piston with a rod operatively connected to the movable jaw, means for admitting fluid under pressure to one end of the cylinder and for cutting it oil. from the source of supply cylim er in connection with each other, a fluid ressureescape from one end-of the cylin er, and resilient means for moving the piston in-the cylinder when its two ends ,are m connection with each other, substantially as specified.
4. The combination of the fixed and movable jaws of the vise, a power cylinder having a piston with rod for acting upon said movable jaw, a fluid pressure 'pi e having branches communicatlng both wit the front and rear ends of the cylinder, a valve whereby pressure may be directed to one end of the cylinder and cut off from the opposite end, -or the ends of the cylinder may be put in while placing the two ends of thecommunication with each other and cut ofi y from the pressure pipe, and means for moving the jaw of the vise underthe latter conditions, substantially ass ecified In testimony whereof, "have signed my name to this specification, in the presence of two subscribing witnesses.
