United States Patent F PAGE TURNING DEVICE Wayne R. Brenneke, Anderson, Ind.

Application November 8, 1956, Serial No. 621,147

4 Claims. (Cl. 40-104) r[lhis invention relates to 4a page turning device, and more particularly to one for use by paralyzed or otherwise incapacitated people in turning the pages of a book, magazine or the like.

Heretofore the person incapacitated to such an extent as to be unable to use his larms or hands has been at a serious disadvantage insofar `as reading is concerned, and more particularly insofar -as the mechanics of turning the pages of a book or magazine 'are concerned. lt has been necessary for such people to rely upon others to do the reading or at least to turn the pages. It is, therefore, the primary object of the present invention to provide a device of such character and construction that even the most seriously incapacitated Iand paralyzed person may readily and easily cause the pages to be turned.

It is =a still further object of the present invention to provide a device of the character described which is relatively economioal in price :and has ia minimum number of working parts.

The full nature of the invention will be understood from the accompanying drawings and 'the following description and claims:

Fig. 1 is a top plan view with the cover removed, of the invention.

Fig. 2 is a side elevation view thereof with a side of the housing removed.

Fig. 3 is a vertical section view taken on lines 3-3 of Fig. l in the direction of the arrows.

In the drawings the housing is provided for the mechanism. An opening 11 is formed in the upper wall 12 of the housing to permit the arm or section 13 of the suction tube 14 to be passed therethrough. A second opening 15 is provided in the top of the housing to enable the column 16 having "a rotating arrn 17 to be passed therethrough.

The suction tube includes the elongated portion 18 which is connected to the suction fan housing 19, the fan (not shown) within the housing being driven by the motor 20. The fan housing and motor are pivotally connected at 21 to the opposed, upwardly extending brackets 22. These brackets are secured to the bottom 23 of the housing through the medium of the screws 24 or other suitable means.

The elongated portion of the suction tube assembly rests intermediate its ends upon the -elevating `and lowering cam 25 mounted 4on the shaft 26. With the turning of the cam by motor 27 (also connected to the bottom of the housing by screws 28 or other suitable media) the mouth 14a of the suction tube is elevated or lowered with respect to the top of the housing upon which will be resting `a magazine, ra book or other reading material (not shown). and :arranged that the mouth of the tube will be bnought into abutment with the upper right-hand corner of the right-hand page of the book, magazine or the like, when the assembly is in its lowermost position as determined by the cam 'and gravity.

The shaft also causes the column 16 to rotate and with The suction tube assembly is so constructed 2,791 ,849 Patented May 14, 1957 it the page turning or rotating arm. This is accomplished through the provision of miter gears 29 and 30 which are in mesh yand connected respectively to shaft 26 and column 16. lt is desirable that the rotating arm be of such a |length as to come in under the mouth of the suction tube, in order to turn the pages from right to left in the proper fashion and manner. Because of this fact it is, of course, imperative that the construction and arrangement ofthe suction tube assembly yand of the page turning assembly be such that the mouth of the suction tube is elevated to a point above the plane of the page turning arm at the time that the arm is traversing the area of the suction tube. That is to say, it is imperative that the suction tube be elevated to enable the arm to pass under it in -a free and unobstructed fashion.

In use the page turning arm will normally first be at rest in the general position shown in Fig. l with the mouth of the suction tube at a point lower than the plane of that arm as shown in Fig. 2. ln order to enable the paralyzed or otherwise incapacitated person to sta-rt the mechanism a pressure pad may be provided, such pad being in effect a switch, the momentary closing of which by-passes microswitch 32.

By applying slight pressure to this pad, as is known, the shaft 26 may be turned a suiiicient `amount to enable the cam 31 to actuate the microswitch 32. The cam 31 is also connected to the shaft 26 and at a point adjacent the elevating and lowering cam. Once the user has actuated tfhe microswitch lthe motors 20 `and 27 will themselves be started. Motor 27 will drive the shaft 26 through the medium `of the miter gears `and the column 16 will be rotated, turning with it its page turning arm. While this is occuring the elevating and lowering cam will permit the suction tube mouth portion to be llowered into -abutment with the page of the book or magazine being read. Further rotation of the shaft 26 will elevate the suction tube thereby lifting the upper right-hand corner of the page. The suction tube will be elevated as aforesaid, to a point -above the plane traversed by the page turning arm which itself will be rotated in under the page, engaging it and turning it from right to left. Once the `arm is returned to the position shown in Fig. l the page will have been turned and the cycle completed. That is to say, the cam 31 will have been rotated to a point where the microswitch is olf.

While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within t-he spirit of the invention and the scope of the claims are also desired to be protected.
