JOSEPH BROADLEY, OF FAIROAKS, CALIFORNIA.

AUTOMATIC FRAMING-SPACER.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed March 18, 1907. Serial No. 362,857.

To all whom it may cof/wem:

Be it known that I, JOSEPH BROADLEY, a citizen of the United States, residing at Fairoaks, in the county of 'Sacramento and State of California, have invented 'certain new and useful Improvements in Automatic Framing-Spacers; and I do declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to the vvaccompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in carpenters tools, and particularly in the means for marking the spacing on scantlings, plates for the upright studding, joists, or other similar space markings.

My object is to produce a machine which 1 will do the above work automatically and i accurately, thus dispensing with the necessity of doing the same by hand with a Steel square and scratch awl in the usual manner, which is a tedious and tiresome process and often inaccurate, the machine being designed to do the same Work accurately and speedily.

Another object of this invention is to produce a machine which will be simple of construction and inexpensive to manufacture and yet effective for the purpose for which it is designed.

These objects and others I accomplish by means of a spacing `wheel having spring actuated buttons attached thereto whereby are operated with each revolution of said wheel, spring actuated pencils, suitably spaced for marking said spaces; and by such other and further construction as will appear by a perusal of the following Specification and claims In the-drawings similar characters of reference indicate corresponding parts of the several views. f

Figure 1 is a vertical view particularly in section of the im roved device. Fig. 2 is a sectional view o a portion of the device taken on a line 2--2 of Fig. 1.

Referring more particularly to the reference numerals on the drawings 1 represents he scantling on which the marking is to be one.

2 designates the casing frame of the device in the top of which is journaled a shaft 3 carrying a wheel 4, having a plurality of biting teeth 5 on the outer edge thereof for biting into the wood 1 when the machine is in motion, thus preventing silpping or other untrue movement. Secured to both sides of the wheel 4 are springs 6 carrying buttons 7 for the purpose as will appear, Depending from the top of the frame 2 on each side of the wheel 4 are hanging plates 8, secured to which are inclinedl cams 9 with which the buttons 7 are adapted to co-act in a manner as will appear` Arranged in the outer sides of the casing 2 and in the plates S, are inclined rods 10, having nuts 11 at each end thereof. Slidably mounted on said rods are sleeves 12 carrying lugs 13 extending through the plates 8 just in front of the highest end ofI the cams 9.

14 are offsets on the sleeves 12, in which offsets are secured inclined rods 15 carrying pencil holders 16 in a manner as will appear in the description of the operation of the device. Encircling said rods 15 and bearing between said offsets and said pencil holders, are springs 17, the tension of said springs being regulated by means of nuts 18 operating on the upper ends of said rods 15. Pencils 19 are dove tailed into the pencil holders 16.

20 are springs encircling the rods 10 and bearing between the casing 2 and the sleeves 12.

21 are wheels having iianges and journaled at the sides of the casing 2 for the purpose of guiding the device along the scantling. Said flanges may, however, be dispensed with if desired.

22 is an operating handle secured to the frame of the device for the purpose of moving the same over the scantling.

The operation of the device is as follows The wheel 4 is constructed with the circumference thereof e ual to the distance desired to be spaced for fhe centers of the studding, say sixteen inches, which is the distance which scantling and joist are usually spaced. The distance between the pencils 19 is then xed for the width of the studding, say two inches. The operator then grasps the handle 22 and places the machine on the scantling l. The machine is then advanced, the teeth 5 biting into the wood for the purpose of preventing the wheel 4 from slipping. As the machine advances the buttons 7 engage with the inclined `cams 9, the springs 6 being compressed as said buttons travel over" the said inclines. When the tops of said inllO clines are reached the said buttons 7 leave the same and the springs 6 drive them against the buttons 13. This action drives the sleeves l2 downward on the rods 10, thus incidentally driving the pencils 19 against the wood 1, thus marking the position for and Width apart of the studding. At the instant that the said marl?` is made, the buttons 7 leave the buttons 13 and the springs 17 and 20 pull the pencils 19 from the wood 1, when the machine again travels free until another revolution is described, when the same operation described above takes place, and so on until the whole scantling is s aced as desired.

Thus it will be seen that have produced an automatic spacing device for the purpose described which does the work rapidlyand effectively, whereby much time and energy is saved. which is now expended in doing said spacing by hand.

It will of course be understood that any size wheel and any distance between pencils may be used, although those set forth herein are the most commonly used.

While in this specication I have set forth the present and preferred detail-of construction of the device, in practice changes may be made in the form of construction and details of mechanism within the scope of the appended claims without departing from the spirit of the invention.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is 1. In a device of the character described, a frame, a shaft mounted for rotation in said frame, a wheel carried by said shaft, spring actuated pencils arranged in said frame and movable transversely of said wheel, means for actuating said pencils, a spring actuated device carried by said wheel and adapted to operate said pencil moving lmeans at each revolution of said wheel.

2. In a device of the character described a frame, a shaft journaled in the top thereof, a wheel secured to the center of said shaft, spring actuated buttons disposed on each side of said wheels, spring actuated pencils arranged in said frame, and means f or operating said pencils by said buttons with each revolution of said wheel, as set forth.

3. In a device of the character described a frame, a shaft Iiournaled in the top thereof, a wheel secured to the center of said shaft, spring actuated buttons disposed on each side of said wheel, downwardly depending plates on said frame on each side of said wheel, inclined cams on said plates adapted to receive said buttons, and spring actuated pencils arranged in said frame and having push buttons extending through said plates just infront of the highest end of said inclined cams, as set forth.

4. In a device of the character described a frame, a shaft j ournaled in the top thereof, a wheel secured to the center of said shaft, spring actuated buttons disposed on each side of said wheel, downwardly pending plates from said frame, on each sideof said wheel, inclined cams on said plates adaptedv to receive said buttons, inclined rods secured in the said frame and said plates, sleeves mounted on said rods and having buttons extending through said plates just in front of the highest ends of said inclined cams, springs bearing between said sleeves and the sides of said frame, offsets on said sleeves, inclined rods arranged in said offsets and having pencil holders secured to their lower ends, pencils secured in said holders, springs bearing between said holders and said offsets, and nuts mounted on the upper ends of said last named rods, and a handle secured to said frame, as specified.

51 In a device of the kind described aframe, a rotating wheel therein, spring actuated pencil holders in said frame, means for driving said holders downward with each revolution of said wheel, and pencils dove tailed into said holders, as specified.

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

JOSEPH BROADLEY. Witnesses:
