Connected to the crank arms 78, 79, are upstanding links 80, 81 respectively, which have their upper ends pivotally connected, as at 82, 88 respectively, to the inner ends of the crank arms 84, 85 respectively, carried on one end of the crank shafts 86, 87 respectively. y

Secured to the inner face of'each `of the end bars 31 of the carriage frame is a vertically extending channel iron which constitutes a guide for a vertically shiftable frame support. s One of said guides is indicated at 88, and the other at 89. The guides 88 and 89 are disposed centrally with respect to the end bars 81 and extend a substantial distance thereabove, and said guides are oppositely disposed with respect to each other and further open inwardly. Secured to the outer face of the guides y88, 89, and extending tranversely thereof are n supporting brackets 90, 91 respectively, and each of said brackets, at each end thereof, kis provided with a bearing. The bearings carried by the -bracketi'90 are indicated at 92, and those by the bracket Qlfat 93. Mounted lin the bearings 92 is the crank shaft 86, and mounted in the bearings 93 is the Vcrank shaft 87. Mounted on the crank shaft 86 is Veo a spring controlled lever 94 provided. with an inwardly extending supporting lug 95. Mounted on the crank shaft'87 and arranged in alignment with the spring controlled lever arm 94, is a lever arm 96 provided with an inwardly extending .supportinf lug 97. Formed integral with'the crank arm 84 is an upstanding spring controlled lever arm 98 provided withan inwardly extending supporting lug 99, and formed integral with ythe crank arm 85 is a spring controlled rip-standing lever arm 100 provided with an'inwardly extendingsupporting lug 101. The lever arm 98 is arranged in alignment with the lever arm 100. The controlling springs for the

lever arms

94, 96, 98 and 100 are indicated at 102, and each of which is connected at its upper end to a lateral pin 108 carried by the lever arm with which the spring associates, and the latter has its lower end anchored to a pin 104, carried by the inner face ofA an end bar of the frame of the carriage. The controlling` springs 102 normally maintain the

lever arms

94, 96,98 and 100 at an outward inclination with respect to the guides 84 and 85. .The lever arms 94 and 102 extend, when vin normal position, in an opposite direction with respect to the

lever arms

96 and 100. The

lugs

95, 97, 99 and 101 provide means for supporting the stretcher frame, to" be hereinafter referred to, in horizontal posi'- tion, when the

lever arms

94, 96, 98 and 100 are swung inwardly against 'the action of .their controlling springs and to the position illustrated with respect to the

lever arms

96 and 100, asshown in Figurer 8. y The shafts 77, 86 and 87 connect the

lever arms

94, 96, 98 and 100 together so that if any one of thelever arms is shifted inwardly, the other lever arms will be moved simultaneously therewith, Byv this arrangement the .su} )porting lugs are shifted synehronously to and from supporting position with respect to the stretcher frame.

Mounted in the guide 88 is a vertically movable stretcher frame 'support 105 of a length vwhen in lowered po'sitio'n'to depend below the supporting member 85. The support 105 is Islidably connected to the guide 88 by a l'coupling member 106, which is secured to the upper end of the guide 88 and overlaps` the member-105,"and the latter is also slidably connected to the guide 88 by a strap' 107, which overlaps the guide 88 and the member 105 and which is secured to the inner face of that end barof the frame of the carriage to which the guide 88' is secured. vi I Mounted" in the guide 89 isa vertically movable stretcher frame support 108 of a length when in lowered -position to depend below thesupporting member 88. The support 108-is slida-bly connected to the guide 89 by a coupling ymember109which'is secured to the upperend of the guide 89 and overlaps the member 108, and the latter is also slidably connected to the guide 89 by a strap 110, which overlaps the guide 89 and the member 108 and which is secured to the inner face of that end bar of the frame of the carriage to which the guide 89 is secured. The upper end of the support 105, as well as the support 108 is cut away to provide a seat 111 and a pair of oppositely extending flared arms 112, and secured to the upper end of each-support is a wear 'strap 113, which conforms in contourto the said end of the support and is further secured tov each side thereof, as at 114.

The supports 105 and 106 are elevated simultaneously through the medium of a shifting mechanism therefor, and 'said mechanism includes a pair of elevating arms 115, 116. The arm 115 is carried on one end ofl a' shaft r117, which is mounted in the bearings 7 5,'and the arm 116 is carried on the other end of the shaft 117. The arms 115, 116 are arranged between the supporting members 35 and 38 and the end bars 31 of the carriage frame. The arms 115 and 116 are angle-shaped in contour and the vertical leg thereof is fixed to the shaft 117 j and is of less height than the length ofthe *horizon-tal leg'I thereof. The lhorizontal Llegs of the arms ,115, 116 are arrangedin the `path of the supports l105, 108 respectively, `and said armsfurther constitute `brakes :for

maintaining the Carriage stationary when the supports 105,` 108 are in lowered "position,

and :when the supports are in such position the said Yarms are forced `against the hed upon which the vtrack rails 28, 29 are arranged. The shifting mechanism further includes a lever arm 118, which is `secured centrally to the shaft 117 and has its outer ftion shownin dotted lines, Figure 3. The

shape of the arms 115, llisCsuch that when the shifting mechanism `is operatedto elevate the supports 105, T108', .the saidk arms will not Contact'with thebasesor ioor upon which the track rails 28, '29 are secured. Thehar y64 acts'as a'prot'ecting medium, not only for the shaft y'71, but -also to prevent the voperator from stumbling over `the lever arm 118. K

` The stretching frame for thehide consists of two 4rpairofendhars:andthe fend hars of one pair are indicatedf119,-j120, and theend `hars of the other pair at 121, 122. -

The'loars
