VISE.

Application filled September T 0 all whom it may concern:

Be it known that I, CHARLES WV. MORGAN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Vise, of which the following is a full, clear, and exact description.

My invention relates to improvements in visas or holding appliances used in bench testing of small machines such as automo bile magnetos, generators or starters; and the object of my improvement is to provide a. vise with adjustable jaws to grip machines of various dimensions and only at points that can safely withstand pressure from the jaws; or are particularly accessible.

I attain the object of my invention by the use of three adjustable clamping members, two of which are located on one side of a machine to be secured in the vise and the third of which is located on the other side.

I incorporated three adjustable, clamping members in a vise for the first time, in what- I choose to term the original form described in this specification; and later, I simplified the structure of my vise in what I term the improved form described in a supplementary specification.

In the drawings forming a part of this specification, like characters of reference indicate corresponding parts in all views.

Fig. 1., shows the original form of my vise completely assembled; Fig. 2.. a side and rear elevation of the front adjustable arm and its locking member; Fig. a plan view ofthe pressure screw block; Fig. 1., a rear L-member; Fig. 5., a plan view of the carriage lock; Fig. 6., diagrammatic plan views of the vise holding a long generator of small diameter and also holding a short generator of large diameter.

I will now describe my vise shown in Fig. 1. 1 is the carriage of the vise supported on parallel guiding members or rods 2, 2. These members 2, 2 permit a forward or backward adjustment of carriage 1. The carriage may be locked rigidly to the guiding members or rods by means of the L- shaped lock 3 and the set screw 4. This lock 3 is shown in greater detail in Fig. 5. Referring to Fig. 5., a screw 5 is used to hold the lock in place when pushing the carriage forward on the parallel rods. In car riage 1, there is a trough 6 running parallel to the rods 2, 2. In this trough and lying below the surface of the carriage, there is a rod 7 rigidly mounted at each end in the cast-ing of the ca *riage. A hole 8 in the vertical wall of the trough, forms the support for one end of the rod 7 while a hole in an extension 9 of the carriage forms the support for the other end of 7. Pivotally mounted on this rod 7, slides an arm 10 and arm lock 11. See also Fig. 2. The set screw 12 in the tapped end of lock 11, when tightened, cants the arm 10 on the rod 7 so as to make it seize. This. assists the normal tendency of the arm to cant and seize when it receives pressure from a device being held in the vise. Pressure from such a device is indicated by an arrow in F ig. 2. Referring to Fig. 1., and Fig. 3., surrounding both 10 and 11 there is an at justable block 13. This block is provided with sufiicient clearance so that it may he slid up or down on 10 and 11. The push screw 1a mounted in 13 exerts pressure against the device being held in the vise. Two movable L- shaped members 15, 15 Fig. 1., and Fig. 4., form the rear clamping members or rear jaw of the vise. )1 rod 16 perpendicular to the rods 2, 2 forms the guide for the members 15, 15. The horizontal parts 17, 17 on the L- members 15, 15 press upward on the under side of the carriage.

Having described the essential parts composing my original form of vise, I will now describe its use. The magneto, generator or starter to be secured in my vise is placed on the carriage 1, Fig. 1., in proper alignment with the pulley of the motor that is to drive it and the rear L-members are adjusted to suit its particular dimensions. Then the. push screw arm 10 with its lock 11 and surrounding block 18 are pushed up against the magneto so that the pressure screw 1 1 presses at a desirable point. Set screw 12 is then tightened thus locking 10 rigidly on rod 7 and final pressure is secured by turning 14 to the limit of strain desired. WVhen removing work from the vise, the pressure screw and lock are released, the whole unit brought back and rotated to the right or left below the surface of the carriage thus leaving the space clear in front to remove the work.

In Fig. 6., (a) and (b), I show plan view diagrams of my vise holding generators of different diameters.- On. generator 27 there IUD happens to be rigid bracket 29 attached to it at the rear side and a frail box 80 containing delicate mechanisms attached to it on the front side. I represent the two mem bers 15, 15 by black arrows and the pressure screw let by a third arrow. These arrows are numbered to correspond with the objects which they represent. The broken line AB represents the. center line of a belt or chain for driving the machine under test. In both figures the carriage is shown at the same distance from AB. Now by closely studying both conditions (a) and (b) it will be apparent that to accommodate both generators 27 and 28, the jaws of the visemustbe adjustable as described. Ifthe members 15, 15 were not adjustable but fixed in the positions indicated in (a) it is plainly apparent they could not accommodate generator 28 in And too, if the rear jaw of my vise weretcomposed of asingle rigid member extending transversely from one side of the vise to the other, the peculiar shape of the lug 29 on 27 would interfere. Furthermore, if ,27 hadno lug 29,.the width of the solidrear awwould causeit to interfere with the accessibility'tothe=brush rigging atitherear of generator-28. As to the advantages of adjusting front jaw 14:, it is evident that :were let fixed centrally while it would accommodate 27, it would press close to or against the delicate brush rigging on 28 and were it located to accommodate 28 satisfactorily, it would then be obliged to press against the delicate mechanism 30 on 27.

I am not aware that prior to my invention any vise has been made with three adjustable clamping members and therefore I claim this feature broadly.

I claim:

1. 111a vise oizholding appliance,,the combinal'ion ofethreelaterally] adjustable. clamping members to grip a device secured in it, two ofsaid'laterally ad ustableclamp ng members being located on one side of ,the

device and the third laterally adjustable clamping .members on the opposite side.

2. .In a vise. or holding-appliance, the combination comprising a carriage mounted on parallel -guides means oflocking the carriageto the guides at any desired point; a

.rearjaw verticaltothe upper face of the carriage and fadjustable width and positionpafront jaw arranged'toform an opening of variable Width between it and the rear jaw and arranged to press against the work secured in the vise at any desired point.

In a vise or holding appliance for bench testing'of automobile magnetos, generators or starters, the combination compris ing a carriage to receive the work; parallel guides or rodssupporting the carriage; a lock to secure the carriage to the rods at any desired point; two L-shaped members forming the rear jaw of the vise eacii vertical to the carriage top and adjustable in a direction transverse to the parallel guides; a front jaw composed of a pressure screw mounted in a block, an arm and arm-lock adjacent thereto, the block being movable along the arm and look; a rod acting as a pivotal support for the arm and arm-lock, the rod being rigidly fixed in portions of the casting of the carriage and lying in a trough in the carr'age, the length ofthe rod and its position permitting movement of the arm and arm-lock toward oraway from the two members forming the rear aw.

in a vise indicated in Fig. 1., the carriage 1 to receive the work; the parallel rods 2, 2 mounted in the frames .2, 2, the said rods 2,-2 providing support forthe carriage land permitting a means of adjusting the position of the carriage; the lock 3 to securethe carriage 1 to the rods 2, 2 at any desired point; the members 15, 15 forming the rear jawof the vise; the rod 16 to support members 15, 15, the said rod being supported at its ends in lugs forming a part of the carriage 1; the arm 10; the arm-lock 11 with set screw 12; the block 13; the screw i l, the said members 10, 11, 12, 13 and 14 composing .in combination the front jaw of .the vise; the rod 7 supported in portions of the carriage, to serve as a pivotal support .for the arm 10 andarm-lock 11; all substantially as shown for the purpose specitied.

5. Ina vise or holding appliance, a rear jaw adjustable in width and position, and a front aw having a pressure element adjustabletransversely, longitudinally and vertically.
