ELDRIDGE M. BROWN, OF GREENBANK, WEST VIRGINIA.

CARPENTERS BENCH.

SPECIFICATION forming part of Letters Patent No. 537,338, dated April 9, 1895.

Application filed November 27,1894- $erial No. 530,11 1. (No model.)

Be it known that I, ELDRIDGE M. BROWN, of Greenbank, in the county of Pocahontas and State of West Virginia, have invented anew and Improved Carpenters Bench, of which the following is a full, clear, and exact description.

My invention relates to improvements in carpenters benches and especially to certain attachments therefor; and the object of my invention is to prod ucea bench on which cabinet or carpenter work may be quickly and firmly clamped up and held, also to provide a convenient means for clamping and holding other work on the bench, and further, to provide in connection with the bench, a vise which may be instantly operated, which is adapted to hold a large range of 4 work, and which is also adapted to hold it securely.

To these ends my invention consists of certain features of construction and combina:

tions of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar figures of referenceindicate corresponding parts in all the views.

Figure 1 is a perspective view of a bench,

Fig. 2 is an enon the'line 3 3 of Fig. 2; and Fig. 4 is ade tail cross section, on the line 4.-4. of Fig. 1, through the vise.

The bench is in the main of the usualconstruction, and has a longitudinal groove 9 in the top to receive certain kinds of work, and has rows of, holes 11 in the top, these being of the usual kind to receive the pins or dogs 12 against which the work is held. The holder for holding the work against the pins is new and has a plunger 13 which slides on the table top opposite the pins 12, and the ,,plunger has, preferably, an enlarged head 14:

which should be of rubber in order that it may have a good bearing against the work which is clamped between it and the pins. The

plunger has its upper surface formed into a toothed rack 15 which engages a gear wheel 16 which is journaled ina housing 17, this being fastened to the bench top and having

transverse guides

18 and 19 above the plunger 13, and as the plunger is held snugly between the sides of the housing 17, the latter serves as a guide to prevent the displacement of the plunger.v

The gear wheel 16 is provided with an up wardly extending handle 20, by which it may be turned and the plunger moved, and this handle is recessed on the under side, as shown at 21 in Fig. 2, in which recess is pivoted, as shown at 22, the bell crank 23 which is normally pressed outward at itsupper end by a spring 24, and the lower end of the bell crank connects with a slide rod 25 moving in a slot 26 in the gear wheel 16, and the slide bar or rod has at its lower end a rigid pawl or blade 27 which is adapted to engage teeth 28 in the edges of the openings in the sides of the housing, and the pawl, by engaging these teeth, holds the gear wheel and plunger 13 in such a way that the plunger cannot be pushed back. through the housing.

When work is to be clamped between the plunger 13 and the pins 12, the bell crank 23 is pressed so as to lift the .pawl 27 from engagement with the teeth in the housing, and the handle 20 is thrown forward so as to throw back the plunger 13. The work is placed bedle 20 is then thrown back so as to throw the plunger forward and clamp the work between the plunger and the pins, while the pawl 27 engages the teeth 28 andprevents the plunger from moving back. The plunger 13 is secured to a bottom plate 29 which projects from'one side of it, and to this is hinged, as shown at 30, a transverse bar 31 which is provided with gage marks in order that the work adjacent to it may be easily gaged, and the hinge arrangement enables the bar to be turned up,'as shown in dotted lines in Fig. 3, when it is. not to be used. The outer end of the bar 31 is doubled over, as shown at 33, so asgto slide in a guide groove 34 in the front edge of the bench, and the bar is backed by a brace 32, as shown in Fig. 1. It is also provided with clips 35 which project from its forward edge and are adapted to clamp work which is held on the bench. To enable the Q The bench is provided on the front side and near one end with a transverse slot 36, which extends preferably through one of the bench legs, and in this is held an arm 37 which is fastened by a pin 38, and the arm is provided with holes 39 to receive the pin and to permit the arm to be adjusted in and out. On the outer end of the arm is pivoted the jaw 40 of the vise, which is straight on its inner side and which extends preferably to a point level with the bench top so that it may clamp convenient] y, between itself and the bench, any article which it is desired to hold, and the lower end of the jaw carries a rack 41 which meshes with a segmental rack 42 journaled in a case 43 which is fastened to the bench, and the rack 42 is provided with an upwardlyextending handle 44 which may be grasped to turn the rack 42, and this, acting on the rack 41, swings the jaw 40 in or out, as the case may be.

A latch 45 is held to slide in the handle 44, this latch having an out-turned upper end 46 which serves as a handle and enables it to be easily pulled up, butit is normally pressed down by a spring 47 and it is thus thrown into engagement with the teeth in the case 43, and the latch serves to fasten the

racks

42 and 41 and also the jaw 40. When the racks are to be moved and the jaw adjusted, the latch is pulled up and the handle 44 moved, and then, by releasing the latch, it springs into engagement with the teeth 48 and fastens the jaw.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with the bench, the plunger slidable thereon and the mechanism for working the plunger, of the laterally extending gage bar hinged to the plunger and provided with work holding clips, substantially as described.

2. The combination, with the bench, the sliding plunger thereon and the plunger-working mechanism, of the gage bar having a hinge connection with the plunger, aguide for the gage bar, and work holding clips on the gage bar, substantially as described.

3. The combination of a bench having a slot at one side, a plunger mounted on the bench and movable parallel to the slot, means for moving said plunger and locking the same in position, and a gage bar hinged at one end to the plunger and having a bent portion adapted to slide in said slot in the bench, substantially as set forth.

4. The combination of a bench having a slot at one side and a recess extending into said slot and forming an enlargement thereof, a plunger mounted on the bench and movable parallel to the slot, means for moving said plunger and locking the same in position, and a gage bar hinged at one end to the plunger and having at the other end a bent portion adapted to pass through the recess in the bench and slide in said slot, substantially as set forth.

5. The combination of abench having a dog, a plunger movably mounted thereon adapted to clamp the work on the bench, and a gage carried by said plunger and extending over the face of the bench, substantially as set forth.

6. Thecombination of a bench, a plunger movably mounted thereon, a gage-bar hinged at one end to the said plunger and extending over the face of the bench, the other end of said gage-bar being provided with means for holding it to the bench, substantially as set forth.

7. The combination of a bench, a housing thereon comprising parallel sides having aligned perforations, one side of said housing being provided with a recess having a series of ratchet-teeth arranged concentric with its perforation, a plunger mounted to slide in the housing and provided with a rack surface, a handled gear journaled between the perforations in the side of the housing with its teeth adapted to engage the rack surface of the plunger, and a locking device carried by the gear for lockin g the same to the housing, said locking device comprising alever and a pawl connected thereto and adapted to engage the ratchet-teeth on the side of the housing, substantially as set forth.

8. The combination of a bench, a housing thereon comprising parallel sides, said hous ing having a series of ratchet-teeth, a plunger arranged to play between the sides of the hous ing and provided with a rack surface, a handled gear journaled between the sides of the housing with its teeth engaging the rack surface of the plunger, said gear havingarecess formed transversely across it, a pawl located in said recess and adapted to engage the ratchet-teeth on the housing, and an elbow lever pivoted to said gear with one arm connected to the said pawl and the other arm arranged adjacent to the handle, substantially as set forth.
