House Numbers in Concrete — You 

 Can See Them from Your Car 



THE latest style in house numbers in 

 Pasadena, California, utilizes concrete 

 blocks in which the numbers are molded. 

 These are set out on the 

 edge of the curb so that 

 he who runs (in an auto- 

 mobile) may read without 

 getting out of his car and 

 walking up to the house 

 to find out whether.it is 

 the place he is looking for 

 or not. 



The blocks are only 

 four by seven inches, 

 face surface, with tri- 

 angular sides, that slope 

 back from the street. 

 The ruler shown in the 

 picture is placed so as 

 to give an idea of the 

 size of the lettering. 



Concrete blocks bearing the 

 house numbers are set on the 

 curb in front of the residences 



Setting Broken Bones by a 

 Portable Machine 



ANEW machine for setting fractures ot 

 the legs has been designed and pat- 

 ented by John H. Wilting of Buffalo, N. Y. 

 One of the most interesting features of the 

 apparatus is its light weight, thirty-five 

 pounds. The average fracture-setting ap- 

 paratus is too heavy to be moved about 



from place to place. This one may be car- 

 ried by the physician to the patient. 



When the machine is unpacked the case 

 acts as a rest for the body of the patient. 

 Two arms support the legs. These arms 

 are so arranged that the injured member 

 may be set so it will be 

 exactly the same length 

 as the uninjured leg. 

 The measure of the un- 

 injured leg is taken and 

 the injured leg is drawn 

 out to correspond to it. 



Movable supports are 

 provided for the limbs. 

 Hence there is no strain 

 on the fractured leg. The 

 supports are made of 

 wood fiber so that X-ray 

 pictures may be taken of 

 the leg while it is rest- 

 ing on the supports. A 

 plaster cast may be put 

 on the fractured leg while the patient is on 

 the machine. 



When the machine is packed up it fits 

 compactly in the case. This apparatus 

 should be very useful for army purposes 

 because it is so easy to move it about. 



The case is the size of an ordinary 

 suitcase, and is made of black walnut, with 

 a dust-proof cover. The large amount of 

 aluminum and fiber which enters into the 

 construction of the apparatus explains its 

 extreme lightness. 



A fracture-setting device which may be operated anywhere. The entire apparatus may be packed 

 up in the case on which the patient's shoulders are resting, and it weighs only thirty-five pounds
