GEORGE H. SQUIER, OF TREMPEALEAU, VISCONSIN.

VISEB SPECIFICATION forming part of Letters Patent N o. 436,641, dated September 16, 1890.

Application filed October 31, 1889- Serial No. 328,799. (No model.)

T0 all whom, it may concern.-

Be it known that I, GEORGE I-I. SQUIER, of Trempealeau, in the county of rlrenripealeau and State of Wisconsin, have invented a new and useful Improvement in Vises, of which the following is a full, clear, and exact description.

My invention relates to an improvement in vises, and has for its object to provide a device whose jaws shall have a very wide opening, and wherein this opening may at will be indefinitely increased, and also to provide for a much greater swing than heretofore, it being understood that it is not necessary that the vertical swing should be equally great throughout the ent-ire extent of the opening of the jaws, since bodies of large superficies, for which such a vise is required, are comparatively thin.

A further object of the invention is to provide a device which, by reason of interchangeable jaws, shall be adapted to as large a range of work as possible, and especially one which may be quickly and easily transformed into an efficient lathe.

My invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the device. Fig. 2 is a central vertical section en line 2 2 of Fig. 1. Fig. 3 is a horizontal section on line 3 3 of Fig. et. Fig.4isa\fertical longitudinal section through the sliding carrier or head. Fig. 5 is a transverse vertical section on line 5 5 of Fig. 3. Fig. 6 is a horizontal section through a modified form of sliding carrier oI head. Fig. 7 is a transverse sect-ion on line 7 7 of Fig. 6. Figs. S and 9 are side elevations of attachments utilized to convert the vise into a lathe. Fig. 10 is a partial plan view of a modified form of the sliding carrier or head; and Fig. 11 is a side view of the same.

In a bench 10 a suitable longitudinal channel is cut of any desired length, preferably extending from end to end, in which channel in the construction of the device the slideway is braced at suitable intervals in its length by means of yokes 15.

The carrier or head 16, adapted to travel in the slideway A, consists of a casting or castings of any suitable construction fitted externally to move freely in the said slideway. The carrier or head is ordinarily constructed rectangular in general contour, and is provided near its forward end with asoeket, in which one clamping-jaw 17 of the vise is inserted. This carrier or head is also provided with a longitudinal, essentially central, channel 18, of varied diameter, extending from'a point at or near the center to the rear end. Within the forward end of the channel 18, which is at this point usually circular, a cam 19 is located and held to turn freely therein by reason of the trunnions 20 of the cam being journaled in opposite sides of the carrier or head, as best shown in Fig. 4, the cam being so constructed that its middle zone rises gradually, so as to forminclined planes adapted to bear against the end of a dog 21, held to slide in the outer portion of the channel 1S. It will thus be observed that by this formation the cam 19 partakes of the nature of an eccentric. A rectangular recess orbore is produced vertically in the cam and its trunnions, adapted to receive the lower squared end of a key 22, which key is preferably shaped somewhat in the form yof a T, as illustrated in Fig. 4t, the office of the key being to revolve the cam 19 when the carrier or head is to be given a forward movement. The key 22 may be readily detached from its seat in the cam when not required for use.

The outer end of the dog 21 is carried in the direction of the teeth 14 of the slideway,

TCO

as best shown in Fig. 3, and upon the outer side face of this angular section of the dog a contact-face 23 is formed, which face is of a height equal to the length of the teeth 14 and provided with teeth 24, adapted to mesh or contact with the 'slideway-teeth 14.-. A spring 25 is attached to the dog and to the carrier or head, which spring usually consists of a piece of suitable Wire having one end secured to the carrieror head and the other end to the inner side of the dog immediately at the rear of its contact-face, the central portion of the spring being in loop form, as best shown in Fig. 3. The forwardly-projecting member of the spring 25 is so inclined to the horizontal member that when the dog is pressed backward by the rotation of the cam 19 a downward pressure is exerted upon the horizontal member, and when the dog is released from the cam the spring acts to restore the former to its normal position.

In the operation of the carrier or head it is obvious that asthe eccentric surface of the cam is brought to bear upon the inner end of the dog 21 the contact-face 23 of said dog will be made to mesh with the teeth 14 of the slideway, and as the said eccentric surface of the cam is continued in contact with the dog the dog acts as a lever to push the carrier or end of the dog. tains the lever 27 in a position essentially to an engagement with the rack 14.

head forward, since the cam is attached directly to the carrier or head. When the concentric face of the cam approaches the dog, the spring 25 commences to act and forces the said dog to its normal position, whereupon at the next revolution of the cam the carrier or head is again propelled forward in a similar manner to that above described.

In Fig. 6 I have illustrated aslightly-modified form of the interior mechanism of the carrier or head, which has the advantage of holding the dog against the rack of the slideway in such manner as to prevent all possibility of its slipping. The cam 19 remains the same; but one trunnion 20 is provided with an abrupt shoulder 26, adapt-ed for contact with the inner end of a centrally-fulcrumed lever 27, which lever is located immediately above the dog 21, and the rear end of said lever is bent downward and introduced into a channel 28, formed in the outer end of the dog, as best shown in Fig. 7, whereby as the cam is revolved, when the shoulder 26 of the trunnion contacts with the inner end of the lever 27, the said inner end is carriedin one direction against the tension of a spring 29, and the outer end, attached to the dog,is carried in the opposite direction, and the contact-face of said dog is thereby forced This action takes place just as the eccentric surface of the cam commences to act upon theinner The spring 29 normally reparallel with the longitudinal axis of the carrier. or head, and a second spring 30, located at the rear end of the carrier or head within the channel 18, has a bearing at its upper end against theorear end of the contact-face of the dog, which spring 30 has a tendency at all times to force the dog inward and keep it in contact with the cam. Thus it will be 0bserved that the jaw 17 may be fed forward, as occasion may demand, to approach a fixed jaw, hereinafter described. The carrier or head is readily slipped backward to increase the distance between the sliding jaw and a fixed jaw when the dog 21 is out of Contact with the rack or in theposition illustrated in Fig. 3.

The lixed jaw 31 isintroduced into asocket formed in a head or block 32, which block is supported in any suitable or approved manner at one end of the table 10 in such a way that the fixed jaw will be immediately opposite the sliding jaw 17. rlhis is usually effected by mounting the block 32 upon a pedestal 33, attached to the yfloor or to any other support upon which the bench rests, a brace 331L extending from the block to the table, or other equivalent mechanism may be substituted for the brace. This head or block 32 carrying the fixed jaw is entirely independent of the table 10 and the slideway, and no connection whatever is made between this fixed jaw and the sliding jaw.

If in practice it is found desirable, thc

block 32 of the stationary jaw 31 may be fed forward in any approved manner, a screw 34 being illustrated in the drawings tov accomplish that end..

IOC

From the head or block 32 an angled bracket It will be understood that the fixed jaw may be attached to either end of the bench, and by a corresponding arrangement of the parts the device may be rendered, respectively, either a right or a left hand vise.

A feature of the invention consists in making the jaws removable and interchangeable, by which arrangement not only can jaws of the usual form be employed, but other and special forms of every possible description may be also used, requiring but a few seconds to Substitute one for the other, since each jaw is introduced into a socket or its equivalent produced in that portion of the device adapted to carry the jaws.

From the foregoing description it will be observed that by producing a table or bench with the slideway described, and also by-reason of the wide opening obtained between the jaws 17 and 3l, it presents, essentially, the features of a lathe-bed, and that the sockets holding the jaws may be made also to hold standards for carrying the working portions of a lathe.

In Figs. 8 and 9 I have illustrated such IIO standards, the one 40 (shown in Fig. S) being adapted to carry a pulley 4l, which may re-` volve on a pin 42. When so constructed, the opposite standard 43 is provided witha similar projecting and aligning pin 44, as shown in dotted lines. This form of standards is especially adapted for wood-turning.

Instead of the above construction the standard 40 may be more perfectly formed, the pulley being made to revolve in bearings upon the top of the standard and having its outer end fitted to receive any of the usual forms of chucks, as illustrated at 45. [n the latter event the opposite center 46 may be of the ordinary construction.

Thestandards 40 and 43, and likewise the standards or Shanks having the jaws l7 and 3l attached, are preferably given a gradual inclination in the direction of each other.

The lathe-rest 47 is of the usual construction, and is only introduced to show the Inanner of its adjustment, which is by means of a block 48 passed beneath the slideways.

The auger-carrying arm heretofore referred to usually consists of the following parts: a shaft b, formed of a round rod of steel or other metal having at one end any of the usual forms of auger-holding devices h', the other end being square to fit into a common bit. The shaft is held to revolve in a sleeve b2, secured at its center by the set-screw 38 to the slotted arm of the bracket 35, as heretofore set forth. Thus the sleeve and the shaft it carries are capable of receiving angular movement in a horizontal plane.

In Figs. 10 and ll I have shown a second modification of the carrier or head in which the supplemental pawl 50 is hinged at the end carrying the dog 53. This supplemental pawl is held in position to contact with the rack 14 by a spring 5l, and is provided with a pin 52, capable of extending upward through the slideway A. By reason of the additional pawl 50 a continuously-progressive forward movement may be imparted to the carrier or head. By pushing the pin 52 to one side the pawl 50 may be disconnected from the rack when desired. rlhe addition of the pawl 50 is very desirable when a yielding or elastic body is to be compressed more than it is possible to accomplish with one turn of the cam, as Without the pawl the expansion of the body would force the carrier or head backward and release the dog from the rack.I

I desire it to be distinctly understood that the form of the cam 2O may be changed, and that, though specific construction of details has been shown and described, I do not confine myself thereto, as other equivalent construction may be employed without departing from the spirit of the invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with a guideway, of a sliding head or carrier, a dog having independent longitudinal movement on the head or carrier, movable bodily therewith, and projecting at its outer end laterally beyond one side of the carrier into engagement with one Wall or face of the guideway, and an actuating device carried by the sliding head and engaging the inner end of the dog, whereby the force exerted on the dog will cause the sliding head to be moved forwardly along the. sliding way, substantially as set forth.
