HEiiGIiT-MEAsuRINe DEVICE.

Application filed August 17, 1925. Serial No. 50,546.

This invention relates to a height measuring device for use in schools, gymnasiums, or in like places, the invention having for an object to provide a simple device of this sort capable of easy manipulation, and

which will show the height of the person be ing measured in inches and fractions'and cent1meters and fract1ons thereof.

F or further comprehension of the inven-' tion, and of the object and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig.1 of the drawing is a side View showing my improved height measuring device.

Fig. 2 is a face view of the indicator. "Fig. 3 is a horizontal sectional view taken 20 on the line 3-3of Fig. '2. V

Fig. 4 is an enlarged detail vertical sec tional view taken on the line 44 of Fig. 1. Fig. 5 is a detail horizontal sectional view showing the braking device, this view being taken on the line 5-5 of Fig. 6.

Fig. 6 is a fragmentary vertical sectional view taken on the line 66 of Fig. 5.

In constructing my mproved height measuring device Iprovide an upright casing or 7. 1 housing 10 which may be constructed of.

wood,'metal or suitable material as desired, and which is formed with a tapering top part 10 ending in a diminished neck 11.. In this housing a fiat bar 12 of lesslength than the housing is suspended for vertical movement, this bar having on one half of front side scale markings 13in feet, inches and fractions of inches, and on the other half of front side scale markings 14in meters, centimeters, and fractions of centimeters. An opening 15 is covered by a window of glass or suitable transparent material 16, 'is formed in the front of the housing to enable the scale markings on the bar to be seen as they come opposite the indicating marks 17 on the housing or window.

The bar 12 is suspended from a cable 20' which passes out through the neck 11 at the top of the housing in suitable tubing 20 around a pair of pulleys 21, 22 mounted in elbow casings 23 suitably secured to ceiling 10 and downward from the latter pulley, this cable being connected by a swivel element 24 with a stem 25 on a disk 26 which is adapted to rest on the head of the person being measured. The other end of the cable of the latter. I

has a swivel connection with a shackle 27 mounted on the upper end of the bar 12. t The bar 12is guided in the housing 10 by means of a numberof sets of rollers, there wbeingv one set at each corner-of the bar, each set comprising a pairof rollers 30 and'31 which engage respectively the front and rear of the housing 10, and another roller 32 which engages the side wall of the housing, these rollers being mounted on suitable brackets 33 fixed to the bar 12 at the corners To cause the bar 10 to remain in the=position to which ithas been raised, when the plate or disk 26 rests on the head of the person being measured, I may form ratchet teeth 35, 36 on the opposite sidesof the-bar' 3P which are spaced according to the-divisions 'of the respective scales 1 3 and 14 and which are engaged by pawls 37' fixed on horizontal shafts journaled in the front and rear wallsof the casing, these shafts projecting through the front-wall of the casing and having handles 38" on their projecting ends, the pawls being urged against the ratchet teetlr'by means of springs 39;

Fixed on the shafts 38 are gears 4.2 which mesh with the pinions 43 on other shafts 44" extending below the shafts 38, these having also fixed thereto the cams 45 which are adaptedto engage the remote ends of a pair] of rods t6 which extend alongbehind the, bar 12 and have adjacent ends connected to an arm 47 which is pivoted as at 48 011 the rear Wall of the housing and carries a pair of accurately spaced brake elements 49 on its free ends. The rods46 are guided by means of the ap'ert-ured member 50 through which the rods extend. v The brake arm 47 is held in and returnedto neutral position by means of a pair of resilient pins 52-which project from the rear wall of the housing on opposite sidesof a pin 53 fixed to the brake arm.

When either pawl is moved sufficiently to and attached to the wall by screws 55. hen the pawl is moved suflicient distance to engage behind this latch the cam 45 operated in conjunction with the pawl will be i the 'latterfr ee to move. e r a g I i T 0} guide the cable over the' pulleys'in the elbow casings 23 the latter are shown "with removable} segments 60 in which are quadf ran'talribs 61 Whichengage in the enlarged iouter'ip'ortions of the groove in each pulley.
