MIRROR Filed June 18, 1929 gwmmtoz Henry @Schrader Patented Nov. 1.7, Y1931 ma-f? MIRROR Application led June 18,
This invention relates to an improvement in mirrors and more particularly to a mirror for the detection of error in the posture of individuals. y Y
In its preferred embodiment this devicey consists of a mirror of determined height and breadth having graduations indicated or im.-
pressed on the face thereof and through the use ofwhich an individual may detect any error in posture and at the same time perceivev how to correct such error. j
Prior to this invention no definite attempt has been made to produce aldevice through the use of which children or otherindividuals '15 might readily perceive, with a view to correcting, errors in postureg The average individual is prone to continue from day to day without due regard for correctness of carriage and, with the exception of occasional suggestions by either a doctor or physical instructor, he is little, or if at all,'aware of the fact that gradually and through carelessness he is growing into a slight deformity of one kind or other. Tipped heads, droopingV shoulders, body twists and other errors in posture, however slight, are exceedingly injurious and with children often develop and grow to assume proportions out of all contemplated reason. In the following specitication. applicant discloses a mirror of a determined height and breadth having graduations both vertical and horizontal in the'face thereof and by means of which the reflected image of the individual clearly indicates whether' or not such individual holds himself correctly. n i
The principal object of this invention therefore is to provide a graduated mirror ,by means of'which individuals may observe and appreciate errors in posture and determine how to correct them. j p
Another object of this invention is to provide a device of this type which is adjustable to accurately determine in inches ,0r other forms of measurement the extent of which an individuals posture is in error.
Other and further objects of this invention will be apparent from a consideration of vthe following specifica-tion when taken in con- 1929. serial No. 371,888.

The ,frame llconsists of base members 13 suitably joined together and supported in spaced relation to each other by means of cross supports 14C. 'In the present emboditg. ment the frame is shown formed from su'it- A75 ably shaped sections of pipe joined together by unions 16. It is to be understood, how'- 'ever, that applicant contemplates producing this frame `from other materials in slightly 1; varying forms as may be consistent with the particular location and luse of the device. The base members 13y are formed-from a plurality of sections 15. The unions 16 are formed to receive the end of sections 15 and accommodate the ends of the supports `14. 85 Centrally of the base members 13 and fitted into enlarged unions 18 areuprights or hol!- low posts 19. The posts 19;;terminatein collars 20 upon which are mounted set screws 21. rf.; A telescoping post 23 is mountedwithin each 90 of the posts 19 and adjustably secured by means of the set screw21. One of the posts 23 terminates in a collar 27 fitted thereon in a manner such as to permit rotation thereof.
The collar 27 is lrnurled as at 28 to facilitate 95 ready rotation thereof and is formed'with a centrally located opening` 30 therethrough, said opening being threaded to `receivethe shaft 33 of the .ipivotal'support 82. The sup.- port 32 corresponds to the housing 25 in thatv 100 it accommodates the rodswhich support the l yzu mirror. The upper portion of the support 32 is fitted to provide a spirit level for a purpose which will be later brought out. The shaft 33 of the support 32 is at all time in threaded engagement with the collar 27 and when said collar is rotated in one direction or another the'shatt 33 Ais moved into or out of said collar.
The mirror 12 is preferably formed from the best grade plateglass obtainable and ter-A minates upon its edges in a slight bevel 37.
Prior toV silvering, the mirror glass is ground or otherwise suitably provided with vertical graduations 38 and horizontal graduations 39. In the present embodiment, the vertical graduations 38 are three inches apart and the horizontal graduations 39 one and one-half 4inches apart. It is obvious, however, that thespacingofthe graduations 38 and 39 may be differently arranged according tothe particular use to which the mirror is put as, for instance, indetermining any incorrectness in the Y'posture of a small child, the graduations of necessity must be closcrtogether, whereas, in determining the errors of a grown person, the graduations could remain VVsubstantially as they are shown inthe drawings. When the graduations have been placed upon the rear face of the mirror, said mirror is silvered and a suitable backing 40 is placed thereagainst to protectthe silvered surface. The backing 40 is held in place against the "mirror by straps 41 which are secured by screws 42.
The straps are preferably horizontally' arranged along the backing and are formed with flanges 43, the ends 44 of which vare bent to engage the beveled surface 37 of vthe mirror.
It is contemplated that should the mirror be of such pro-portions that the straps '41would not successfully support said mirror,`the glass could be drilled and screws used to secure the backing 40 upon the mirror. The lowermost strap 4l is formed with two or more depending langes 45 which engage the under beveled edge of said' mirror.
vvSupported by straps 47, which in turn are secured in any suitable manner to the center horizontal strap 41, are pivot members 48 which extend beyond the vertical coniines oit' .said mirror and enter on the one side the vhousing 25 and on the other the support 32.
f V`Al'ock 'nut 49 is provided in the housing 25 'tightening 'of which prevents any pivoting ofr the mirror.
The spiritlevel 35, formed in the upper part'of the support 32, is provided to determine whether or not the mirror is vertically aligned. If itis found through the spirit level that the mirror tips slightly to the left, the collar 27 is rotated causing the shaft 30 to be extended,l thus raising the pivot 32 and "verti'c'ally'aligning said mirror. While it is 'true that a certain amount of adjustment may be'had by adjusting .the telescoping posts 23,
51. The level 51 is mounted to move with the mirror and determines the vertical alignment thereof in a manner at right angles to that of the spirit level 35. lhile the graduations 38 may be absolutely vertically adjusted, the mirror might be tipped 'forwardly or backwardly thusV causing the horizontal graduations 39 to render inaccurate dimensions. In connection with the spirit level 51, it is contemplated to provide a chart which will indicate ythat upon tipping the mirror to a certain angle, registered by the spirit level, the individual, whose image is to be reflected, will know he is required to stand a given distance from said mirror in order that it may accurately register the reiiection.
A further aid in determining the extent of error in posture is made possible through the use of a rule 53 mounted adjacent one vertical edge of the mirror. This rule is secured by brackets 54 to the post 19 and is arranged to measure the distance from the floor to the top of the mirror which, as shown in the drawings, is approximately six feet. ,"Whether the mirror 12 be raised or lowered, so'long as one of the horizontal graduations39 is in line with one of the inch or foot graduations of the rule 53, it is possible to very quickly calculate the extent of error in posture ofV an individual standing before the mirror.
Although applicant 'has shown and described but one modification of this invention, it is not intendedv that he belimited thereto, since other modifications or adaptations may be made without departing'from the spirit and scope of this invention as set forth in the hereunto annexed claims. l
Having thus set v.forth my invention what I claim as new and for which I desire protection by Letters Patent is:
1. A device for the detection ot errors in posture comprising a frame having upstanding-hollow members, posts telescopically engaging said members, a mirror pivotally mounted on said posts, means Jforming one of said mirror pivots adapted to indicate vertical alignment of said mirror and further means formed in said mirror for definingthe extent of posture error. l
