COMBINATION-TOOL.

Specification of Letters Patent. Pa;ented Oct. 10, 1905.

Application filed August 1, 1904. Serial No. 219,076-

To (/J/ 1/71/0711, it may concern:

Be it known that I, Tnouas H. BRADLEY, a

citizen of the United States, residing at \Va- E tertown, in the county of Jefferson and State of New York, have invented certain new and i prise the number generally in use.

useful improvements in Combination-Tools, of which the following is a specification.

This invention relates to improvements in i combination-tools designed for use by carthe employment of which they are enabled to size in a proper manner it requires levers or bars of different thickness and strength. In my present invention I have shown a lever which is capable of being effectively applied to three different sizes of jacks, which com- Another feature of the invention consists in utilizing practically the whole length of the bar or lever in operating a jack-screw, because in so doing 1 gain the advantage of a greater leverage, thereby rendering the work perform certain parts of their work with? greater convenience and effectiveness, with a less number of tools to be provided and cared for, and with a considerable saving in the cost and maintenance of their working equipment. The invention relates particularly to a com- 5 bination-tool comprising a metallic bar or 'le- T The invention consists principally of a steel bar or lever substantially of the length and weight of a light crowbar, such as commonly used by carpenters and kindred artisans, and is preferably forged or formed from a single piece of metal.

The object of the invention is to provide a simple, convenient, light, and durable working tool or implement which consists of combining in one part a pinch or crow bar having a flat chisel-like projection at one end with a jack-sorew-operating lever integrally formed on the opposite end.

A prominent feature of the invention consists 1n providlng a comblnation bar or lever, i

one end of which is particularly adapted for use in operating jack-screws, and wherein I provide a series of shouldered projections, each of which is turned to a diameter and length suitable for inserting into and operably fitting the transverse holes which pass through the heads of the screws of the different-sized jacks. In order to illustrate the object and value of this feature of my invention.

it is deemed proper at this time to explain j intended that the sectlons should vary in that there are several sizes of jack-screws of raising or lowering a heavy load or weight by means of a jack of the class a coi'nparatively light and easy task. Then by providing the pinch or pry feature to the other end of the bar I complete the combination of a handy and useful contrivance for the several purposes set forth and claimed herein.

The invention consists, further, in providing a V-notch in the flat chisel-like end of the bar, forming thereby a claw which may be employed for pulling or reniovingspikes, &c.

The invention further consists in the constructions and in combinations hereinafter described, and particularly pointed out in the claims.

The invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all of the figures, and in which Figure l is a perspective view showing the prominent features embodied in my invention. Fig. 2 is a view showing an elevation of a jack-screw and also my combination-tool applied to the jack as an operating-lever. Fig. 3 is a view of a modified form of the device shown in Fig. 1 from which the claw and pinch features have been omitted.

The bar 2, preferably of steel, is formed at one end with an angular projection 3, intended principally for use as a pinch or pry bar.

4: represents a claw formed by forging or cutting a V-notch in the end of the projection 3 and is for use in pulling nails or spikes.

6, '7, and 8 represent a series of integral sections or projections forged or turned on the upper end of the bar 2. As will be seen by reference to the drawings each of said sections is of an even diameter throughout its entire length, and each succeeding section is shown and intended to have a substantially increased diameter or thickness. It is also made and in use and that in operating each i length in about the same proportion that they increase in thickness. The object in providing several diflerent-sized sections is for the purpose of adapting the device for use in operating the various sizes of jack-screws in use by carpenters and other artisans employing such implements. The jack-screws in common use to-day are practically alike in construction and operation, and so far as the application of my invention to them is concerned they are all substantially the same. In all jack-screws, so far as my knowledge goes,the screw is provided with an enlarged head at its upper end, and through this head transverse holes or sockets are formed, into which the operating-lever is inserted. In applying my invention the small section 6 at the small end of the bar 2 (which is made to lit and operate the smallest-sized jack-screw) is inserted into one of the transverse holes or sockets referred to until it is stopped by the shoulder 6. Then by turning or swinging said bar to the right or left the screw is either raised or lowered. The second section 7 is employed in like manner in operating a jack-screw next larger in size, and the third section 8 may be applied to a still larger one.

Fig. 2 of the drawings shows the bar 2 applied to a jack of intermediate size, which requires a lever having the diameter of section 7, and the shoulder 7 serves to hold the bar in the position shown. The drawings show only three sections, and while that number has been found to be sufficient for the general use of such a device still I do not wish to limit my invention to the specific number of sections as shown, and I may prefer to increase the number to four or five. The latter feature of the invention may also be employed in connection with devices other than jackscrews and for a variety of purposes not specified and shown.

7 and 8 represent shoulders similar in form and use to the shoulder 6 and will be understood without further explanation. The portion of the bar 2 designated by the number 9 is intended to be formed substantially as shown on the drawings, so as to conform to the hand of the person using the said bar for pinching or prying heavy objects or when pulling nails and the like.

10 represents a jack-screw such as employed by builders and other workmen.

11 is the head of the screw, and 12 is one of a number of transverse holes or sockets extending through the head 11, into which the operating lever or bar is inserted.

13 is a swiveled cap or block surmounting the screw-head 11.

14: in Fig. 3 represents a portion of the bar 2 intended for use as a handle. This is a modified form of the invention and has reference to a device for operating jack-screws and like devices and wherein the other features of the combination-tool have been eliminated.

It will be obvious to any one skilled in the art that various modifications may be made in the device that I have described and shown without departing from the spirit of my invention, and I therefore do not restrict myself to the precise construction herein shown and described.

VVhatI claim, and desire to secure by Letters Patent, is'

The within lever-tool consisting of the bar formed at one end with a plurality of shouldered sections increasing in length and diameter as they extend toward the central portion of said bar, substantially as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.
