Be it known that I, Fmnanron C. Giocar- HEAD, a subject of the King of Great Britain and a resident of Denver, in the countyof Denver and State.I ofr Colorado, have mvented a new and Improved Telescoping Pocket-Rule, of which the following 1s a full, clear, and exact description.
The invention relates to measuring lnstruments, and its object is to provide a new and improved telescoping pocket rule, which 1s simple and durable in construction, cheap to manufacture, vand arranged to fold c ompactly and take up comparatively little room and to allow convenient extending or folding with the use of but one hand. y For the purpose mentioned, use is made of a plurality of telescoping sections provided with enlarged rear portions having sliding en- Eagement with the following section and aving a contracted front end for the enlarged rear end of a preceding section to abut against.
A practical embodiment of the invention is represented in the. accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a plan view of the telesco ing pocket rule with the sections extended; 1g. 2 is an enlarged sectional side elevation of the same; Fig. 3 is a similar view of the same with the sections folded; Fig. 4 is a cross section of the same; Fig. 5 is a cross section of a modified form of the telescoping pocket rule; Fig. 6 is a sectional side elevation of the same; Fig. 7 is a sectional side elevation of a modified form of stop for the telescoping sections; Fig. 8 is an inverted sectional plan view of the same; and Fig. V9 is a cross section of another modified form of the telescoping pocket rule.
The telescoping pocket rule, illustrated in Figs. 1, 2, 3 and 4, consists essentially of a lurality of teleseoping sections A, B, C and provided on thelr upper and under `faces wlth the usual graduation representing linear measurement, as plainly indicated 1in Fig. 1. The forward end of the first section A is provided with a hook E adapted to engage the head of aboard or other article on which the rule is to be used to ermit of slidin y the sections A, B and C into extended position by having hold of the rule with but one hand. The rear end of the last section D is rovided with a removable cap F normally astened in place by screws F- or other suitable means, 1t being understood that when the cap F is removed access is had to the. interior of the section D and the remaining'sections to allow of oiling the same so as to insure an easy sliding of one section on the other. The first section A is lpreferably made solid and its rear end A is enj larged to slidingly engage the next section B, which latter has its forward end B contracted to form a sto A to abut against, with a view to limit the for the bearing end outward sliding motion of the' first section A relative to the second section B. lhe
second section B has its rear end B2 enlarged to slidingly engage the third section C, which latter has its front end C, contracted to form a stop for the enlarged rear end B2 of the second section B. 'lhe third section C has its rear end C2 enlarged to slidingly engage the last section D, and the latter has its forward end D contracted to form a stop for the enlarged end C2. 'lhus by the arranement described the enlarged portions A', 2, C2 slidingly engage the sections B, C and D at the inside thereof so that the graduations on the sections are not marred on moving the sections into extended or closed positions, as the wear is on the enlarged ends A', B2, C2 and not on the graduated faces of the sections A, B and C. The sections B, C and D are preferably made of sheet metal, bent into box-like shape in cross section as plainly indicated in Fig. 4, so that the tclescoping pocket rule can be 4cheaply manufactured.
Inthe modified form shown in Figs. 5 and (i, the first section A2 is similar to the one described above, while the following sections B3, Ca are provided at their rear ends with raised bearing surfaces B210* slidingly en aging the following sections C3, D2, and t e forward ends of the sections are provided with inwardly-extending flanges G to limit the outward sliding movement of the sections.
In the modified form shown in Figs. 7 and 8, the rear end of one telescoping section Il is provided with a struck-up lug H adapted to abut against a struck-up lug I ofthe next following section I so as to limit the outward sliding movement of one section relative to the other. The raised bearing surfaces B4 and C4 may be formed both on top and bottom or only at the bottom, as indicated in Fig. 9. In this case, the first section As is similar to the sections A2 and A above described, while the remaining sections A, C5 and D3 are box-like in shape, and the sections B'i and C5 are provided with raised bearings B6 and C at their under sides only, as will be readily understood by reference to'Fig. 9. By reference to Fig. 1 it will be noticed t-hat the hook E is approximately about one-half the width of the first section A to permit of conveniently using the rule both for butt and calipering measurementsl .The ends B, C', D are shownextended in a forward direction but may be turned under in a rearward direction to form the stops.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:l
l. A telescoping pocket rule, comprising` a plurality of telesooping sections, the first section being solid and having one end enlarged and provided with a hook at its other end, the other sections being formed of sheet metal bent into tubular form, and each having one end larger and its other end smaller than the intermediate portion, the hook of the first section being of a length approximately equal to one half the thickness of the last sect-ion.
2. A telescoping pocket rule, comprising a plurality of telescoping sections, the first section having one end enlarged and provided with a hook at its other end, the other sections having one end larger and its other end smaller than the intermediate portion, the hook of the first section being of a length less than the thickness of the last section.
3. A telescoping pocket rule, comprising a plurality of telescoping sections similar in cross section and all except the first section made of a single piece of sheet material bent into tubular form, the first section being solid, the sections being provided with integral raised bearing surfaces and stops to limit the outward sliding of'the sections, a hook on the outer end of the first section, and a removable cap on the rear end of the last section.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
