COMBINATION-TOOL.

SPECIFICATION forming part of Letters Patent No. 649,422, dated May 8, 1900.

Application filed July 6, 1899,

To 1127 71-71mm if nmypmwern:

lie it known that we, FRANK L. FRY and (HARLES A. KUENZEL, citizens of the United States, residing at Philadelphia, county of lhiladelphia,and Stateof Pennsylvania,have

invented a certain new and useful Improvement in Combinatiomlools, of which the following is a specification.

Our invention relates to a new and useful to improvement in a combination-tool consisting of a l r vel and spirit-level, and has for its object to provide an effective combinationtool of this description, each member of which maybe used as eifectually as though not combined with the other members, while greatly reducing the cost of manufacture and accomplishing results which have heretofore not been attainable by the ordinary tools.

i lVith these ends in view this invention con- 2o sists tthe details of construction and combinat. lIOf elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this inrention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying draw ings, forming a part of this specification, in which- Figure l is aperspective of a combinationtool made in accordance with our improvement, showing the blade adj ustedt-o be used as a square; Fig. 2, a side elevation showing the blade adjusted for producing the obtuse and acute bevels; Fig. 23, a similar view showing the blade 'adj usted to the end of the stock;

Fig.4, a similar view, showing the blade so adjusted as to produce a T-square or plumb,

and Fig. 5a section showing the blade folded 40 for easy transportationbr storage.

In carrying out our invention as here embodied we provide a stock A, a 'portion of which is slotted, as indicated at B, and has seuured therebetween the blade 0 by means of the sot-screw and thumb-nut D. This setscrew passes through the slots E, formed in the sides of the stock, so as to permit the adjustment of the blade lengthwise of the stock, as will be readily understood. The blade also $0 is slotted, as indicated at F, and this slot is Elerial No. 722.915. (No model.)

turned, as shown at G. The object of the peculiar shape of the slot F is to bring the blade in proper relation to the stock for certain purposes, which is accomplished by adjusting the blade so that the set-screw may pass into the turned portion G thereof. The free end of the blade has a right angle ll formed thereon which may be utilized for squaring purposes, and when this blade is to be folded it is then utilized for holding it in position, since it fits within a corresponding recess formed in the stock, as clearly shown in Fig. 5. hen in this position, the blade is secured against displacement by the setting up of the thumb-nut. A spirit-levelIis set within the edge of the stock and so serves for leveling purposes in the usual manner, while a corresponding spirit-level J is set in one end of the stock and is utilized as a plumb, this being accomplished by adjusting the blade as shown in Fig. 4, when the latter becomes a straight-edge, and the indication of the spirit-level J will determine the position of both the blade and the stock, or the stock may be placed against a vertical surface',when the indication of the level J will also determine the trueness of said surface.

Our improved tool is especially adapted for use by stair-builders, since thecomplete adjustability of the blade relative to the stock permits its use in places and for purposes for which an ordinary bevel cannot be used, as will be readily understood by those skilled in such work, while at the same time this combination-tool may be used for all purposes for which each member thereof is adapted.

The cost of manufacture of a tool made in accordance with our improvement is but lit-- tle in advance of the cost of an ordinary square or level; but it is far more advantageous than separate tools to produce the same work. \Vhen the blade is folded, as shown, the tool may be stored in a small compass or carried in the pocket and is not liable to become entangled with or injure, surrounding objects.

Having thus fully described our invention, what we claim as new and useful is- In combination with a stock A, having a vertical slot B, a transverse slot E, and an anv gular end H, adapted to lie in the recess; and 5 a thumbscrew working in the slots E'and F,

gular recess at the inner end of the slot-1B; a fi-xd our signatures in the presence of two" blade C, having a slot F,iprovided with "a subscribing witnesses; curved extension G, said blade having an an- FRANK L. FRY.
