STRAP-TRIMMING MACHINE.
Specification of Letters Patent.
Patentedflet. 26, 1915.
Application filed January 25, 1915. 7 Serial No. 4,235.
To (LZZ whom it may concern.
Be it known that I, JAMES M. S. CARROLL, of the city of l Vestmount, in the Provinceof Quebec, Dominion of Canada, have invented certain new and useful Improvements in Strap-Trimming Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.
My invention relates particularly to machines for trimming and more particularly for concaving the deckle straps used on paper making machines for cutting the Web to predetermined width; and the object thereof is to enable the straps to have their corners sharpened without sending them from the paper mill.
The invention may be said briefly to consist of a pair of machine frames each having mounted therein a guide wheel of suit able width to accommodate various sizes of straps, a third and intermediate wheel being located between these guide wheels and adapted to take up the slack in the strap, an adjustable flange being provided to guide the strap relatively to a grinding wheel suitably mounted. For full comprehension, however, of my invention, reference must be had to the accompanying drawings forming a part of this specification in which similar reference characters indicate the same parts, and wherein;
Figure 1 illustrates my improved machine in side elevation; Fig. 2 is a detail sectional view drawn to an enlarged scale and illustrating the strap trimming roller in bearing relation with the strap; Fig. 3 is a detail horizontal sectional view taken on line A B Fig. 2; and Fig. t is a diagrammatic view of the complete machine drawn to a reduced scale.
The machine is divided into three sections each mounted upon an independent frame, such frames being indicated at a, b and c. The section a comprises in addition to its frame a pair of shafts 2 and 3, the shaft 3 being mounted in bearings 4: fixed to the frame and the shaft 2 in a bearing 5 adjustable on the frame relatively to the shaft 3. The shaft 3 carries a guide-wheel consisting of a rim of sufficient width to accommodate straps of different widths. As these deckle straps are usually of substantially square cross-section sufficient space is provided for them between the rim 6 and frame 6 to permit a guiding device 7 to be mounted upon the latterand adjusted to meet different widths of belt. This. guiding device consists of a member of angular form slotted as at 8 to fit over a screw-threaded stud carried rigidly by the frame 7), a butterfly nut 9 serving to clamp the guide in the requlred position to locate the belt centrally relatively to the grinding wheel, the position of this guide, of' course, depending upon the width of the belt to be ground.
' The shaft 2 carries an emery wheel preferably formed with a slightly convex perimeter and equal in length to the greatest width of strap to be ground. The bearing 5 is adjusted relatively to the guide wheel and in a radial direction with relation thereto by means of a screw 16 threaded through a tapped boring in a bearing 17. In order to enable this emery wheel to be adjusted to bring its center in juxtaposition with the center circumferential line of the belt to be ground the bearings 5 and 17 are mounted upon a slide 20 adjusted by means of screws '21. The guide wheel and emery wheel are driven by separate power shafts 24 and 25, the emery wheel having a higher speed than the guide wheel and being operated preferably by its own motor 29. The frame of this section a ofthis machine is preferably fixed and the section 0 preferably adjustable relatively thereto on a base 26 to which it is secured in any position to which it may be adjusted by clamping bolts 27. This sec tion 0 of the machine comprises besides its carrying frame a shaft 30 upon which is mounted a guide wheel of the same construction as the guide wheel 6 in order to accommodate different sizes of straps.
The slack in the strap is taken up by a roller mounted in vertically adjustable bearings 28 on its frame which in turn rests on a base 36 upon which it is adjusted relatively to the framed and is fastened in any position to which it may be adjusted by clamping bolts 27.
The guide wheels may be carried in trunnions supported in any other than described without departing from the spirit of this invention.
Operation: In the operation of my improved deckle strap trimming machine, the strap is slipped on to the rims 6. The sec tion 0 of the machine is then adjusted relatively to the section ato make the strap taut, the slack being taken up by the adjusting roller 35 upwardly to the required extent. The emery wheel is then adjusted to proper position withrelation to the strap.
' The machine may then be started and during operation the emery wheel is fed slowly convex surface, of a pair of strap carrying wheels and adjustable means whereby the belt is guided, substantially as described.
2; In a deckle strap trimming machine the combination witha guide wheel and an independentframe, of an angle iron guide mounted adjustably upon thesaid independent frame in position to guide the strap" operated upon, substantially as described.
3. In a deckle strap trimming machine the combination with a pair of guide wheels adapted to carry a strap, one being stationary and the other adjustable relatively thereto, and means for driving said stationary guide wheel, of an emery wheel having a convex surface and adjustable to and from said stationary guide wheel for the purpose of operating upon said strap, and vertically adjustable means located intermediate of saidguide wheels adapted to bear upon said strap for the purpose of taking up any slack therein.
In testimony whereof I have signed my name to this specification in the presence of two witnesses.
