SPLlNT-TRIMMING MACHINE.

SJE'ECIFICATION forming part of Letters Patent No. 417,604, dated )ecember 17, 1889;

Application filed February '7, 1839. Serial No. 299,021. (No model.)

To all whom it may concern:

Be it known that I, ALFRED E. TENNEY, of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Splint- .lrimming Machines, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates, essentially, to an attachment for machines used in trimming cane, rattan, willow, or other splints for use in the manufacture of chair-bott-oms or other purposes in which it is desirable to have the splint of a uniform width throughout its length.

The objects of my invention are to simplify the construotion and operation of splint-trimming machines, and to render the same more efficient in their functions.

To the aforesaid purposes, my invention consists in the construction, arrangement, and combination of the several parts of the device, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a top view of my improved device. Fig. 2 is a side view; and Fig. 3 is a sectional View taken on the line 3 3 of Fig. 1, showing the edge of the splint in full view.

In the said drawings like numbers of ref erence designate corresponding part throughout.

Referring to the drawings, the number 4 designates a cone-shaped funnel or trumpet having the end piece or nose 5 screw-threadedinto the end of the funnel. This nose 5, I prefer to make of hard steel, to stand wear incidental to the splints A passing through the same. Mounted on top of the funnel is the block 6, securely heldin place by means of the screw 7. The two arms 8 and 9 are pivoted in the block 6 on the

pins

10 and 11, and are connected together by the link 12, which is pivoted on the post 13 and provided with the two pins 14 and 15, which pins enter the

holes

16 and 17, formed in the ends of the arms 8 and 9, whereby the two arms will move together and at all times center the splint passing between them, so that the central line of the splint will at all times be between the trimming-

knives

18 and 19, and the splint -8 and 9.

will be equally trimmed 011 each side, thereby giving a uniform width to the splint.

To the free ends of the arms 8 and 9 are attached the friction-

rolls

20 and 21. These rolls are intended as simple wearing-surfaces,

and are therefore preferably made of hardened steel and immovably heldin place by the

screws

22 and 23. However, if found desirable, the

rolls

20 and 21 may be loosely mounted on the screws, so as to revolve thereon.

The adjusting-screws 24' and 25 are screwthreaded through the sides of the arms 8 and 9, the rounded ends thereof coming in contact with the flattened part of the nose-piece 5, thus limiting the inward travel of the arms The double-armed spring 26 is attached to the block 6 by means of the screw 27, one of each of the arms of the spring being in contact with the arms 8 or 9, thereby causing the free ends of the arms 8 and 9 to be forced inward, and the wearing-

rolls

20 and 21 brought in contact with the splint A.

It is evident that the two arms 8 and 9, by reason of their being connected at one end by the link 12, will at all times move together, thereby keeping the center of the splint A on a central line between the two

trimmingknives

18 and 19, causing the said splint to be equally trimmed on each side.

The device is simple in construction, can be readily attached to existing machines, and is positive in its operation.

Having thus described my invention, I claim as new and desire to secure byLetters Patent 1. The combination of the guiding-funnel provided with the .removable nose-piece, the centeringarms pivoted in the block and carrying the wearing-rolls at one end and connected by the link at the other, and a spring for operating the arms, substantially as herein shown and described.

2. The combination of the guiding-funnel, the centering-arms connected by the link and pivoted to the block, and a spring for causing the free ends of the arms to bear against the splint, substantially as herein shown and described. p

3. The combination of the guiding-funnel 4, provided with the nose-piece 5, centeringarms 8 and 9, pivoted in the block 6 and carrying the
