LOCKING AND ADJUSTING MECHANISM.

assie.

To all whom it may concern:

Be it known that I, RIoHARD LESTER W1Loox, a citizen of the United States, 1'6. siding at Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Locking and Adjusting Mechanism, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention refers to a new and improved locking and adjusting mechanism, more particularly as it relates to means for locking and adjusting an independent member, as ablock, within a movable gate.

It is the object of my invention, among other things, to provide a simple and eflective device, for the general purpose above indicated, that will have a'minimum number of parts requiring manipulation by the operator, and in which there will be practically no possibility of a strain upon any of the parts to throw them out of alinement. i

To these, and other ends, my invention consists in the locking and adjusting mechanism, having certain details of construction and combinations of parts, as will be hereinafter described and more particularly pointed out in the claims.

Referring to the drawings, in which like numerals of reference designate like parts in the several figures;

Figure 1 is a side elevation of my improved mechanism, partly in section;

Fig. 2 is a fragmentary plan view of the gate and the parts adjacent thereto;

Fig. 3 is a plan view of the gate block; and l 1 l Fig. 4 is an end View thereof. 3

My improved mechanism is adapted t be used upon any type of machine having a member operated from a connection or pitman, one end of which may move either a rotary or a straight path, and the other connected with the device herein shown, while the member itself reciprocates in guideways, theconnection between the adjustable.

Mechanism of this generalcharacter is common to heading machines, and 1* have therefore adopted so much of the elements of this type of machine asis necessary to Specification of Letters Patent.

pitman and reciprocating member being describe my invention, calling attention, however, to the fact that it is not limited solely to thisclass of machinery.

Heretofore it has been the practice to se cure the block within the gate by two or more screws arranged so that they pass through the gate upon each side thereof and impinge against the block. In certain forms of such machinery this form is objectionable, because the operator, either through forgetfulnessor carelessness, fails to uniformly adjust all of the screws,

thereby permitting lost motion upon one side and an irregular instead of a uniform wear upon the parts.

Then, again, as thescrews are adjacent to the sides of the gate, they are liable to spread and cramp the gate in its bearings so as to either prevent its movement entirely or create such additional friction as to make it practically inoperative, or throwit out of alinement, so that the punch and dies do not register with each other.

These, and other objections are eliminated in my invention, wherein only a single screw-is used and is so placed as to prevent cramping or strain upon the gate parts. l

The portion of the bed of the machine shown in the drawings is designated by the numeral 1, and in which the gate 2 is slidably mounted, receiving its movement froma pitman 3, which is connected with the gate by meanshereinafter described, and the end of which, (not shown) moves in a rotary path, as is common in the art. 011 the front end of the gate is the punch block 4 having punches 5 mounted therein. The gate is constructed with rearwardly projecting side plates 6, each provided with slots in which is movably mounted the gate block 8. The projecting rear ends of the plates 6 are secured together, against anytendency to spread,by the cap 9, se-

cured in place by the screws 10, and having the lips 11 thereon, that engage lips upon the said plates, thereby insuring a very strong and rigid structure.

Mountedwithin the gate block is a shaft 12, to'which the pitman 3 isseoured by the cap 13 and bolts 14. t

The means for adjusting the gate block relatively to the gate, comprises a wedge 15 that lies between said block and the face 16in the gate, and which is adjustable in one direction by a screw 17, which is threaded through a head 18 upon said wedge and impinges upon the top of said gate block, a jam nut 19 looking said set screw in any of its adjusted positions.

The locking mechanism comprises a single screw 20, threaded through the hood portion 21 of the gate that ties the plates 66 together upon their top sides, said screw abutting against a shoulder 22 in the top of said gate block and is locked in its adjusted positions by a jam nut 23. This screw is located midway between the sides of the gate 2, and as the hood member 21 is a substantially heavy construction there is no possibility of the gate feeling any lateral strain from said screw and only a single screw is required instead of two, as heretofore.

To adjust and lock the gate block, the screw 17 is actuated so as to shift the position of the wedge 15, after which the screw 20 is manipulated to hold said block against the wedge, as is clearly illustrated in Fig. 1 of the drawings. Therefore, to adjust and look said gate block only two screws are required and these operate upon different members.

There are minor changes and alterations that can be made within my invention, asid from those herein suggested, and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described but claim all that falls fairly within the spirit and scope of the appended claims.

'I-Iaving described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a device of the character described, the combination with a member; of a second member movably mounted therein; and means for adjusting. said second member within said first member and looking it in such adjusted position, comprising a movably mounted element having engagement with said second member, means for imparting movement thereto, and means within said first member and engaging said second member for holding this latter member in engagement with said element.

2. In a device of the character described, the combination with a member having openings therein; of a second member movably mounted within said openings; an adjustable member mounted in said first memher and by its position limiting the movement of said second member in one direction; and a locking member movablymounted in said fir member and engaging said second member at a point between said openings to prevent its movement away from said adjustable member.
