 by a pair oi sprockel cl ain into which the hooks catch.

spreader is a sprocket chain D for engaging 

 the apron to convey it through the machine 

 to the wind-up. The apron is buill up in the 

 form of a pad, having two outer layers of 

 canvas and a middle layer of felt. It is as 

 wide as the fabric E and long enough to lap 

 once or twice around the wind-up, forming a 

 smooth cushion for the coated fabric. The 

 apron is stretched between the chains and is 

 in .i shown in the drawing. 



On the rear end of the apron is a narrow 

 metal clamping plate to which the fabric 

 may be quickly and smoothly attached. On 

 its forward end is another metal plate F, 

 curved to fit the wind-up roll. On each end 

 of this plate is a hook for attaching the 

 apron to the chains D, and in the center is 

 another hook G which catches on one of a 

 series of rods in the center of the roll B 

 when the apron readies this point. 



The operation is as follows : The forward 

 end of the apron is hooked to the chains 

 and the rear end is clamped to the fabric. 

 The spreading knife is raised and the ma- 

 chine set in motion. When the rear end of 

 the apron has passed the roll C the knife 

 is lowered and spreading begins. When the 

 plate F reaches the wind-up it is automatically disengaged from 

 the chains ; the hook G catches one of the rods in the center of 

 the roll B ; the apron and fabric are then wound up in the usual 

 manner. Invented by C. J. Landin, and assigned to the Clifton 

 Manufacturing Co., Boston. 



MONG ll" new machines of the month is one fur building 

 r,n i acinus. Its salient parts are a tire core and jack, a 

 n richer drum, a former for shaping the frictioned fabric 

 to the core, and a pair of adjustal fillers, all mounted 



on a frame. 



to the drawing, thi i tioned fabric A is passed 



from the stock reel B around the stretcher 



drum C. The muslin wrapper JJ passes from 



reel under a guide roller E but is 



again brought against the frictioned strip and 



part way around the drum with it, 



forming a brake to prevent it from being un- 



too fast, The wrapper then goes over 



a swinging frame F and is wound up on a 



From the drum the fabric passes over 



a former // and is attached to the tire core /. 



The core, mounted on the holder /, is geared 



to hi el IS i i faster than the drum, to 



he fabric strip a uniform stretch. The 

 former // is shaped like an inverted U and 

 has curved edges which turn up the edges of 

 the strip to shape them for taking the beads. 

 Above the frame are two pointers K and L, 

 under which the center line of the strip passes, 

 serving as a guide to keep the winding in line. 

 A center line for this purpose may be marked 

 on the strip as it is wound on the stock reel, 

 so that the line will come on the upper sur- 

 Eaci of tin fa!«rn- as it •> unwound in the 

 proa >^ of building up the tire.

After the required number of plies are laid on the core the 

 beads are applied and rolled into place j the adjustable, con-

 Converse and F. A. Kress, and assigned to The B. F. Goodrich 

 Co., of New York.
