Whether you are a roofing contractor or a DIY enthusiast, understanding the capabilities of glazed roof tile roll forming machines can help you make informed decisions for your projects. An exhibit known as Die M uhle also shows very plainly a spring arrangement similarly located, by which the movable roll is made to yield to a sudden pressure. 3) A spring device, by which the rolls are made to yield to a breaking strain, whenever a nail or other hard substance enters between them. This spring is also capable of yielding to a sudden pressure by which the adjustable roll is forced back and separated from its companion, by the passage of any hard substance, and of resuming its original tension after such hard substance has passed between the rolls.

The object of the third was merely to prevent injury to the rolls by the entrance of a hard substance, after the passage of which they returned immediately to their former position.

The elements of this claim are five in number: 1, a fixed stretcher bar; 2, means for intermittently feeding the skin over the same; 3, a stationary card above the stretcher bar; 4, a rotary separating brush below the same; 5, mechanism whereby the rotary brush is moved upward and forward into a position in front of the stretcher bar, 'substantially as set forth.' In making his claim the inventor is at liberty to choose his own form of expression, and while the courts may construe the same in view of the specifications and the state of the art, they may not add to or detract from the claim.
