Patented Aug. 9, 1938 2,126,023 UNlTEDI SATES FFECEZ 2,126,023 COMBINATION TOOL Thomas F. McGoldrick, Chicago, 111. Application July 20, 1936, Serial No. 91,502 5 2 Claims. (Cl. 15—105) This invention relates to improvements in com increases the life of the brush at an expenditure bination tools and more particularly the con- - only of the effort to make the exchange. struction of a combined brush and shovel mount With these and other objects in view, refer‘ ed on the same handle so that one does not‘ ence is made to the accompanying sheet of draw interfere with the use of the other. ing which illustrates a‘pre‘ferred form of this in It is an object of this invention to provide a vention with the understanding that detail tool of this character which is simple in con- ~ struction and operation and which may be readily , adapted for use as a brush or shovel by causing a slight change in the horizontal relation be tween the parts and then a reversal in their ver tical relation to place the desired tool in opera tive position. It is a further object to so mount the two tools upon the samehandle to be mov 15 able in relation to each other and to the handle, yet to allow either to be used in its normal man ner without changing the angular relation of the handle to the ground from that customarily employed in the operation of either tool. It is 20 also an object of this invention to provide de tachable means to secure rigidly the tools upon the handle in either position, and when detached . to employ a rotative movement of the handle to assist the changing of the relation of the tools to each other. It is a still further object to pro-‘ vide a brush with detachable and interchangeable bristles so that they may be replaced when worn out or’interchanged when partially worn. The advantages of such a tool are obvious, and its uses are many. While originally contemplated for the use of the men employed to keep the streets of a city clean, it may be used in the same manner in cleaning sidewalks, hallways and , o?ices of buildings, gardens or other places where changes may be made without departing from the scope thereof, and with the understanding that the brush with the interchangeable and re placeable bristles, while preferable, may be re 10 placed by a brush of the ?xed bristle type without departing from the scope of this invention. In the drawing: ‘ ‘ Figure 1 is a view in side elevation of this im proved tool illustrating the position of the respec 15 tive parts when the tool is desired to be used as a brush or push broom. Figure 2 is a view in front elevation of Figure l,‘with a portion of the brush broken away. Figure 3 is a view' similar to Figure 1 illus 20 trating the position of the respective parts when the tool is desired to be used as a shovel, with parts broken away and partly in section. ‘ Figure 4 is an enlarged detail view in section taken on the line 4—4, ‘Figure 2, with parts 25 broken away. . . ‘ ‘ Figure 5 is a viewin section on the line 5—5, _ Figure 1, looking in the‘ directionof. the ‘arrows. Figure 6 is a view similar to Figure 5, taken on the line 6-—6, Figure 1. . ‘ 30 Figure 7 is a top plan view of Figure 3 with the bristles of the brush removed and the handle ferrule broken away. In the embodiment of this invention as illus it is desired to brush surface dirt or debris into small piles, and then shovel the pile into a re trated, the brush I may be of the customary push 35 ceptacle for removal. Therefore, this tool is also the ‘transverse rows of bristles embedded'there in, but it is constructed preferably of ‘a metallic available for home use in the manner of a broom and dust pan. The combined tool is balanced 40 on the handle so that each may be used in the usual way without inconvenience or causing an broom type having a wooden base or back with casing having a flat rectangular base or back 2 closed at the front and the two short sides for 40 detachably mounting rows of bristles 3 arranged unnatural position of the operator, as well as be ing readily changed from one to the other with little effort on the part of the operator on ac 45 count of the lever action of the handle in mak ing a change. It has been found that the bristles in brushes customarily used for this purpose, and which are usually formed in parallel transverse rows, wear unevenly, that is, either the front or ing out turned ?anges 5 along the free edges of 45 rear rows wear sooner than the intermediate rows 50. according to the manner in which the operator holds the handle. Therefore, a brush which is parallel to‘ the long closed front, as hereinafter described. ‘A shovel 4, preferably of stamped metal, hav the sides is mounted upon the back 2 of the brush l with the ?anges 5 engaging in guides 5 provided therefor and secured upon the back 2 so that the shovel may be retracted to position its front approximately in line with the front of the brush, as shown in Figure 1, when the tool is to be used as a push broom, the guides 6 being provided with bristles formed in sections and de _ extended, preferably, at the rear of the back ‘2 tachably secured in the frame of the brush allows to provide rigidity to the connection of the shovel the interchange of partially worn bristles and 4 to the brush I in this position. The exterior 55 2 2,126,023 surface of the back 2 is provided, preferably with an external rib 1 arranged adjacent and parallel to the long closed front between the sides of the shovel 4 to be engaged by the rear end of the shovel to limit its outward movement when the shovel is extended, as shown in Figure 3, when the tool is to be used as a shovel. The brush I mounting the slidable shovel 4 upon its back is attached to a handle 8, which 10 may be of wood or whatever material desired, by providing a metallic sleeve or ferrule 9 to receive the end of the handle 8 which may be attached thereto in any desired manner. The handle ferrule 9 is pivotally attached to the back 2 of 15 the brush I by a frame or bail ID, the free ends of which are preferably out-turned and received in bearing II therefor secured to the back 2 and the center portion attached to the ferrule 9, as shown. To secure the handle 8 in proper relation to the tool when used either as a push broom or as a shovel and to assist in changing the movable relation between the shovel and brush, a con necting link I4 is provided which is mounted to slide within a guide I5 mounted longitudinally upon the ferrule 9. The link I4 is preferably circular in cross-section with one end having a sliding connection I6 with the back of the shovel 4 and the opposite end provided with an operat ing pin or handle I‘! adapted to travel in a lon gitudinal slot I8 provided therefor in the guide l5 which slot is provided at each end with an off set portion I9 to receive the handle I‘! and hold it at each’ end of travel. In the position'shown in Figures 1 and 2, the 35 a requirement for division made in this applica tion. In this type of brush, the bristles are formed in narrow rectangular sections with the upper ends held together by glue or embedded in cement or other similar medium. The sections U! are of such length as to be receivable between the side closures 20 depending from the flat back 2. The front section of bristles 3 is held in posi tion against the front closure 2| depending from 10 the ?at back 2. As many partitions 22 are provided parallel to the front closure 2| as there are sections of bristles to be employed. These partitions 22 are equally spaced apart from each other and the front closure 2| and their ends are secured in any de sired manner to the depending side closure 20. The embedded ends of the section of bristles 2 are inserted to rest against the front closure 2i and each of the partitions 22 and secured thereto in that position by a series of adjustable follower plates 23 preferably mounted upon guides 24 vpass ing freely through the partitions 22 and secured to each follower plate 23, as shown in detail in Figure ll. When the brush sections are in place, the embedded ends are secured against the respec tive partitions 22 and front closure 21 by exerting pressure upon the guides 24, as by screws 25 freely mounted upon the outer follower plate threaded into the next adjacent ?xed partition 22, or by any other desired means, so that the bristles 2 are rigidly held in position and yet may be detached and removed for reversal or interchange with another section. What I claim is: 1. An attachment for a ?at backed brush or tool is adjusted for use as a push broom with the the like having a handle pivoted thereto, including shovel 4 retracted and the link I4 withdrawn Within its casing I5 and the handle I1 held in locked position in the off set slot I9 furthest 140 from the shovel 4. When it is desired to change the tool to a shovel, the handle 8 is depressed and rotated about the bearings I I which will initiate the extension of the shovel 4 in its guides 6 through the locked link I4. The handle I‘! of the link I4 is then rotated out of its locked posi tion and is manually advanced in its slot I8 until the rib ‘I is engaged with the back of the shovel an inverted scoop shaped shovel mounted on the back of said brush, means engaging and guiding the open side edges of the shovel to slide upon the back of the brush, and a connecting link attached to the back of the shovel mounted to slide length wise upon the said handle to extend and retract 4. The tool is then in position to be used as a shovel and is turned with the bristle side of the brush I upward, as shown in Figures 3 and '7. The securing of the link handle I‘! in the off set I9 nearest the shovel 4 locks the tool with the brush and shovel in proper relation. As heretofore stated, it is preferable to employ the particular construction of brush here illus trated which is disclosed and claimed in the ap plicant’s Patent No. 2,112,297, granted March 29, 1938, upon an application ?led in accordance with 2.5 39 3.5 the shovel over the back of the brush, and means to secure the link to the handle at the respective ends of its travel. 2. The structure of claim I wherein the end of 45 the handle is provided with means mounting a sleeve for slidably receiving one end of the con necting link, the other end of the connecting link having a sliding connection with the back of the shovel, said sleeve having a longitudinal slot therein with offsets at each end thereof, and an operating handle mounted upon the received end of the link passing through the slot in the sleeve and adapted to secure the shovel at the op 65 posite ends of travel of the link by engaging said ’ ' link handle in a transverse offset.
