HARRY MATTHEWS AND HERBERT HOLMES,
OF OAKWORTH, NEAR KEIGHLEY,
ENGLAND.
WORK-HOLDER FOR METAL-CUTTING MACHINES.
aosasae.
To all whom it may concern:
Be it known that we, HARRY ll ilA'rrHnws and HERBERT I-IoLMEs, subjects of the King of Great Britain, and residents, respectively, of 53 Vale Terrace, Oakworth, near Keighley, in the county of York, England, and 33 Station road, Oakworth aforesaid, have in vented a certain new and useful Improvement in vVorlcHolders for ldetaLC'utting Machines, of which the following descrip tion, together with the accompanying sheets of drawings, is a specification.
Our invention relates to work-holders for machines for boring, drilling, milling, planing, shaping and slotting metals or the like. As is well known, in these machines the articles to be treated need to be held in order that the cutting tools may perform their usual and well-known functions. It is also known that the devices usually employed for said holding purposes are strips or bars of metal which are secured by bolts to the base piece on which the work is placed, necessitating the application of additional means to support the end of the bar or strip of metal which is not in contact with the article to be treated.
Our present invention consists in the production of an improved adjustable clamp mechanism which will grip the article and retain it firmly and securely.
In the accompanying sheets of drawings:Figure 1 is a side elevation of a device constructed in accordance with our invention. Fig. 2 is a front elevation thereof. Fig. 3 is a sectional side elevation of said device. Fig. 4 is a rear elevation thereof. Fig. 5 is an elevation showing our device in use as mounted upon the bed plate or table of a machine. Fig. 6 is a illustrated by Fig. 5. Figs. 5 and 6 are drawn to a smaller scale than that of the remainder of the parts.
In carrying out our invention, we employ a movable piece or block at having its base a formed with an area to enable it to be supported upright on any part of the bed plate 5 to which it may be laterally shifted, said bed-plate b supporting the work to be treated (as that marked 0). On this block a and at an appropriate angle to the surface a we form an inclined surface d having teeth or serrations 0Z arranged to engage with correspondingly shaped teeth or serra- Specification of Letters Patent.

tions 7 formed in the rear inclined face of a ledge piece or rest f. The plane in which the teeth (Z and f engage is such as to enable the base piece or block a to support the ledge piece f and retain its upper surface j" approximately in the horizontal plane, so that any force acting vertically upon said surface f will be withstood by the engage ment of the teeth f on the part f and those marked (Z on the part a and that without the en'iployment of any additional. means to retain the block a or ledge piece in position relatively to each other or to the bed Z). Arranged to be used in connection with these parts is an arm having a crosshead 9 formed on it, and this arm 9 takes through a slot it made in the block a, said crosshead 9 bearing against the rear surface (Z of said block, as shown by Figs. 3 and 4. By these means said arm 5 and crosshead 9" will hold the ledge piece or rest f in position upon the block a, but by swinging the ledge piece outwardly from the position illustrated, its teeth f will be moved clear of the teeth (Z and the cross head 9 may be slid upon the surface (P, so that said ledge piece 7' may be adjusted to any position along the serrated part (3, as will be readily understood. The block a is mounted anywhere desired upon the bed-plate 7) of a machine, as shown by Figs. 5 and 6, or upon any equivalent bed-plate or like part of any machine to which our invention is applicable.
As illustrated in Figs. 5 and 6, one end of the bar or plate 70 extends over the work 0 which is to be clamped, as at 70 the other end 70 being supported by the rest or ledge piece f, said bar or plate 70 being held firmly in position by the bolt m and nut m, said bolt being varied in length to suit the size of the work to be clamped. It will also be seen that according to the thickness of the work 0, or the distance that its upper surface is from the upper surface of the bed-plate Z), so will the position of the adjustable ledge piece or bloc: f be determined, said ledge piece f being easily and quickly adjusted for dif ferent depths or sizes of work as may be required. The arm 9 may be formed intcgrally with the part f, as by being cast upon it, or it may be screwed into said piece, as shown by Fig. The teeth (Z in the base piece or block a as well as the teeth f in the rest f, may be formed therein either during the process of casting or by being afterward cut with suitable cutting tools in manner Well known.
I claim 1. A clamp comprising a bed for the work, a block laterally movable on the bed, said block having a base to support it upright thereon, said block having a serrated face immovable relatively to its base, a ledge piece or rest having a serrated face to engage the serrated face of said block, a bar or plate adapted to rest on the ledge piece at one end, and at the other end on a piece of Work on the bed, and a clamp for adjustabiy connecting the bar or plate with the WOi'i" bed.
2. A clamp comprising a bed for the Work, a block laterally movable on the bed, said block having a base to support it upright thereon, said block having a serrated face, a ledge piece or rest having a serrated face to engage the serrated face of said block, a bar or plate adapted to rest on the ledge piece at one end, and at the other end on a piece of Work on the bed, and a clamp for adjustably connecting the bar or plate with the Work bed, the cooperating serrated faces of the movable block and the ledge piece or rest being inclined relatively to the supporting face of the Work bed.
3. A clamp comprising a bed for the Work, a block laterally movable on the bed, said block having a base to support it upright thereon, said block having a serrated face immovable relatively to its base and provided with a vertical slot, a ledge piece or rest having a serrated face to engage the serrated face of said block and having an arm extending through the slot of the block and engaging the rear face of the latter, a bar or plate adapted to rest on the ledge piece at one end, and at the other end on a piece of Work on the bed, and a clamp for adjustably connecting the said bar or plate and the Work bed.
t. Means for clamping a piece of work on a bed, comprising a block adapted to be laterally moved on the Work bed anc having a base to support it upright thereon, said block having a vertical slot, a ledge piece or rest having an arm extending through said slot and engag ng the rear face of the block, the said block and ledge piece having inter-engaging serrated faces, ivhereby a bar resting at one end upon the said ledge piece, and at the other end upon the zorl: and clamped in sucn position may hold the piece of Work firmly gripped.
In testimony whereof We have signed our names to this specification in the presence of two subscribing Witnesses.
