Referring in detail to the drawings and more partic- Aularly to Figures 1 5 of the drawings, there is shown a drill guide which includes a ibase that is indicated genervally by the numeral 20, and the base 20 includes |a lower flat surface 21 for engagement with la work surface such as a table 22. The base 20 is provided with a V-shaped recess 23 in the lower portion thereof whereby workpiece to be drilled such as a pipe c an be extended through the -recess 23, in order to help hold the pipe or other member stationary or steady while being worked on.

The numeral 24 indicates a handle which includes a threaded `shank 25 that threadedly engages one of the threaded openings 26 -in the base 20, and the handle 24 provides -a handgrip for use in steadying the device when a workpiece is being drilled. As shown in Figure 5 for example, .the base 20 is provided with an enlarged opening 27, and extending upwardly from the base 2() is a flange 28 which is provided with a curved slot 29, Figure 2. The numeral 30 indicates scale markings or indicia which is arranged on the ange 28 so as to define a gauge or scale, and :a securing element or bolt 31 serves to connect the lower end of an adjustable standard 35 to the iiange 28. The numeral 32 indicates a securing element or bolt which extends through the slot 29 in the ange 28 and the securing element 32 also extends through the standard 35 and has -a wing nut 33 thereon, Figure 1. A pointer 34 is carried by the standard 35, and the pointer 34 is adapted to coact with the scale 30 so as lto provide an accurate means of setting the standard 35 to the desired angular position.

As shown in Figures 2 and 4, there is provided an adjustable slide stop which is indicated generally by the numeral 38, and the standard 35 is provided with an elongated longitudinally extending cutout which is indicated by the numeral 36. Portions of the standard 35 contiguous to the cutout 36 #are tapered -as indicated by the numeral 37. The adjustable slide stop 38 includes a pair of members 39 which are fastened together by means of a securing element such as the bolt 40 which has a wing nut 41 thereon. Edge portions of the members 39 are tapered or inclined `as indicated by the numeral 42 so as to conform to the congura-tion of the adjacent portions 37 of the standard 35.

There is further provided an adjustable support member which is indicated generally by the numeral 43, and the support member 43 includes a pair of elements 44 which are of similar construction, and the elements 44 have portions thereof projecting into the cutout 36. The elements 44 are fastened together by means of bolts 45 which have nuts 46 thereon, Figures 2 and 3. The stop member 38 is adapted to be used for limiting downward travel of the support member 43, and the stop member 38 can be adjusted on the standard 35 so as to permit the length of travel of the support member 43 to be varied or regulated as desired. The edge portions of the elements 44 are tapered or beveled as at 47 so as to insure a snug t with the portions 37 of the standard 35.

There is further provided a bracket which is indicated generally by the numeral 48, and the bracket 48 includes spaced apart portions 49 and 50 which are provided with openings 51, Figure 10, whereby the securing elements such as the bolts 45 can extend throughV these openings 51 in order to fasten the bracket 48 to the support member 43. The bracket 48 further includes a straight section 52 which is provided with a plurality of spaced apart apertures 53, and the numeral 54 indicates each of a plurality of adjustable straps which are arranged contiguous to the bracket 48. The straps 54 are provided with adjustable clasps 55, and the numeral 56 indicates a conventional tool such as an electric drill which is surrounded or held by the straps 54, the drill 56 being provided with the usual bit 57. The straps 54 are fastened to the bracket 48 by means of securing elements such as the bolts 58 which have nuts thereon, and the bolts 58 are adapted to extend through the apertures 53 in the bracket 48. 'Ihe drill l56 is provided with the usual handle 59.

Referring now to Figures 6-9 of the drawings, there is shown a modiied base which is indicated generally by the numeral 60, and the base 60 is adapted to be used in lieu of or instead of the base 20. VThe base 60 includes a bottom portion 61*as well as a pair of angularly arranged ears l62, and the ears -62may be arranged at a 45 angle with respect to the bottom portion 61, Figure 6. The base 60 is provided with an enlarged opening 63 as Well as a V-shap'ed recess 64 through which is adapted to extend or project a member such as the pipe 65 which is being drilled or worked on.

Referring now to Figures ll-16 of the'drawings, there is illustrated a modiiied bracket which is indicatedY generally by the numeral 66, and the bracket 66 is' adapted to be used in place of the bracket 48. The bracket'6'6 comprises a main body member 67 which includes a liat section 68 which is provided with a plurality of spaced apart apertures 69. The member 67 further includes end portions which are provided with slots 70, and there is further provided L-shaped members 71 and 72 which have slots 74 through which extend bolts 73, and the bolts 73 'are adapted to have nuts 75 thereon. Straps such as the straps 54 are adapted to be fastened to the bracket `66, andthe bracket 66 is adapted Vto be connected to the support member 43, as for example by meansY of the bolts 45.

From the foregoing, it is apparent that there has been provided a guide which is especially suitable for use with a tool such as the drill 56. When using the assembly of Figures l-5, the base 20 may be arranged on a vsuitable'work surface such as a table 22, and the V-shaped recess 23 serves to receive a member to be worked on such as a pipe or the like. As shown in Figure 3 for example, there is a space between the pair of elements 39 which permits the support member 43 to slide up and down on the standard 35. Thus, with the workpiece extending through the recess 23, it will be seen that the drill 56 can be gripped by its handle 59 and then the drill can be moved up or down so as to drill a hole in the member such as the pipe. In view of the fact that the drill 56 -is connected to the bracket 48 by means of the straps 54, and since the bracket 48 is fastened to the support member 43 by means of the boltsy 45, it will be seen that up and down movement of the drill 56 with respect to the standard k3S is permissibleso that the bit V57 can be moved to the desired position. Y

r[he stop member 38 is fastened to the standard 35 by means of the bolts 40,' and when the bracket 48 and its associated parts moves downward a suiiicient distance, the stop 38 will be engaged `or contacted so as to limit further downward travel or movement of the support member 43. By loosening the Wing nut 41, the position of the stop 38 can be adjusted on the standard 35, and then the wing nut 41 can be tightened so as to maintain the stop immobile in Vits desired position. Y

The straps 54 which surround the drill 56 are provided with adjustable clasps 55 and this arrangement serves to insure Ythat the straps will accommodate or fit on drills of different shapes Vor sizes. Furthermore, the provision of a plurality of apertures 53 provides a further adjustment since the bolts S Vcan be extended through didierent of these apertures l5,73 whereby the drill 56 can be supported in the desired position. Y Y l Furthermore, by loosening the wing nut 33, the standard 35 can be pivoted about the pin 31, and then the wing 'nu-t33 Vcanbeptightened so as to maintain the standard 35 immobile in its Vadjusted position. The pointer 34 'whichis carried by the standard 35 coactswith the scale markings 30 which provides a means for accurately setting the vstandard 35 and its associated parts at the desired position. For example as'shown in Figurej the vstandardl 35 can be moved from the solid line position to the broken line 'position so that the drill 'can be used for drilling holes or openings in the workpiece atdifferent angles;

The handle 24 is adapted to be gripped so as to provide a means for steadying the device and the handle 24 may have its shank 25 engage either of the pair of threaded openings 26 in the base 20.

In the modification of Figures 6-9, the base 60 is adapted yto be used instead of the base 20, and otherwise the use and construction of the device is the same as previously described. Thus, the base '60 includes the V-shaped recess 64 through which extends the pipe 65, and the ange 28 on theY base 60 provides a pivotal support for the standard 35 in the same manner that the ange 2,8 provides a pivotal support on the base 20.

In Figures'll-l there is illustrated a modied bracket 66 which can be used instead of thebracket 48. Thus, the bracket 66 is adapted to have straps such as the straps 54 fastened thereto as for example by means of the bolts 5S, and the bracket 66 is adapted yto be connected to the support member 43Y by means of the bolts 45. The straps 54 will engage the d-rill such` as the drill 56 so that by manually moving the drill up or down, the bracket 56 'will move up and down and at the same time the support member 43 will move up and down in the cutout 36 of the standard 35. The provision of the slots such as the slots 74 and 70 permit the nuts 75 Ito be loosened on the bolts 73 until the elements 67 and 71 and 72 are in their desired position and then these nuts 75 can be tightened so as to maintain the parts immobile in their desired position. The bolt 58V can -be extended through any of the openings or apertures 69 in the member 67 so as to provide a further adjustment.

The parts can ybe made of any suitable material and in different shapes or sizes.

The handle 24 can be used optionally on either side of the block `or base 20. With the guide of `the present invention, the drill can be used for drilling holes or openings in various types of workpieces. Holes in a vertical or horizontal or angular position can be drilled, and the device can be usedin hard to reach places.

The device is adapted to be used with an electric drill and it will permit or insure more stable operation of a hand drill and it Will make possible straight or angle holes in any type of normally used operation of an electric hand drill. Diliicult to reach places can be drilled, and the device can be used to facilitate the drilling of straight or angle holes in pipes or corners where the use of a V block would normally be used.

The iiange 28 may be made integral with the block or base or else it can be made as a separa-te piece. One or two of the straps 54 may be used and the device will t drills of diierent sizes.

Minor changes in shape, size and rearrangement of details coming within the eld of invention claimed may be ,resorted to in actual practice, if desired.
