The present inventionrelates to a ruling in strument, and, in the present form, to a roller type of ruler.
An object of the invention is to provide an instrument by meansof which a line may be drawn, painted, cut or otherwise made contiguous to another line, such as an edge of amolding or piece of furniture, and at variable distances thereirom' even when the gulding line or edge is curved.
For this purpose the invention, in the preferred form shown herein byway of example, consists of a relatively flat instrument provided with supporting and guiding rollers, the instrument being extensible and be- .7 plication of the instrument in practice;
Fig. 2 is a longitudinal vertical" section throughthe device of Fig. 1;
Fig. 3 is a transverse sectional view on the line 33 of Fig. 1;.
Fig.4 is a detail perspective View of one of the sliding guide clips; Fig. 5 is a perspective view of a modified form of the invention; 7 Fig. 6 is a perspective viewof another modified form of the invention and of a different a plication of its use;
Fig. g is a vertical transverse view taken on the line 77 of Fig. 5;
Fig. 8 is Ia vertical transverse sectionalingjro-ller j t slmilar to the roller- 24; and is view taken on the line 88 of Fig. 6. V Referring in detail to the drawings and particularly to Figs. 1 to 4 inclusive, the embodiment of the inventionhere illustrated comprises two interengaging relatively extensible sections 11 and 12 relat vely movasectional.
sliding extensible movement by .a pair of -.guiding clips 14 and 15. Clip 14 has avertical central portionsecured to the end of the section 12 and is provided'with a top and,
me longitudinally and .secured together for bottom flange, the flanges being of greater length than the central section which fits .within the central cut-out portion 1-8,- and the flanges overlying the upper and lower tacesot the parallel arms '19 and 20 of the, member 11.' The clip 14 is thus fixed with respect to the sec-tion112 and has no movement relative thereto.
Clip 15, similar in construction to the clip 14, fits between tlieparallel arms 19' and 20 andhas its upper and lower flanges secured to'said'arms, so that the clip-15 is fixed to the section :11 and is movable with said section'with respect to the cooperating section 12.- Theconstruction described permitsrela tive longitudinalextensmn of the two seethatany relative movement'between themwill be absolutely rectilinear.
The section 11 is'provided with a supporting roller Qtand with a pair of guide rest arms 27 and 28 which serve as guide rests 'for a paint brush, pencil or-other marker,
and for convenience the section 11 and one tion 50 on the arm 27extends parallel to a projection 51 on the arm 281:0 form; a right angularguide rest to aid the user in holding the marking instrument steady with? respect to the ruler. J 1. i
The section l2is provided with a .supportlikewise provided witha'pair of arms STZ and .38., "Each of these arms isp'rovided with a tions with respect to each other andyinsures and absolutely rectilinear movement of the ruler as a whole in the direction of the edge 10 when the ruler is in use. The section 12 and its arms 37 and 38 may also be provided with openings 30 to serve as pencil or other guides.
Referring to Fig. 5, the sections 111 and 112 correspond to the sections 11 and 12 of Fig. 1; supporting rollers 121 and 131 are provided as before, as are also a pair of guide rollers 139. The guide arms are omitted in this modification, however, and the clips 111 and 115 pass about the outside of the two sections, the clip 114 being secured to the section 112, and the clip 115 secured to the section 111. The arms 116 and 117 of the section 111. cooperating with the arms 119 and 120 of the section 112 are provided on their inner edges with a series of guide rests herein shown as being in the form of small wire loops 121. These serve the purpose of holding in fixed position with respect to the ruler, a pencil, paint brush or other marking instrument. A straight edge guiding rest 123 is provided at the end of the section 111 and is provided with two parallel end arms 150 and 151 which cooperate with the guide portion 128 to form at each end thereof a right angular guide rest.
Referring to Fig. 6, the embodiment of the invention here shown is particularly well adapted for relatively greatly curved edges parallel to which it is desired to draw or paint a line. In this form the ruler 212 is provided with a pair of spaced-apart supporting rollers 221 and 2341. The ruler is provided along its edges on both faces with appropriate graduations, and at one of its ends is provided with a guide rest 223 similar to the guide rest 123 of Fig. 5, and is also provided with a pair of short parallel extensions 250 and 251 to cooperate with the guide rest. The other end of the ruler is provided with an extension 260 at the end of which is carried a single guiding roller 289. The marker may be rested upon the guide rest 223 or simply along the graduated edge of the ruler at the desired distance from the edge 240.
From the foregoing description it will be seen that the invention provides an extensible guide ruler by means of which decorative or constructional lines may be drawn, out, painted or otherwise marked parallel to straight or curved edges; and that the invention provides a small antifrictionally supported instrument for this purpose with guiding means enabling it to follow a base or reference edge of any curvature. Various modification's'may be made in'the construction of the invention Without departing therefrom, as defined by the following claim.
What is claimed is:
A guiding'ruler'of the'character described consisting of "two longitudinally adjustable JOHN W. PHILLIPS.
