BREAK-PIN ATTACHMENT FOR PLOWS SPECIFICATION forming part of Letters Patent No. 373,784, dated November 22, 1887 7 Application filed September 17, 1897. Serial No. 249,971. (No model.)

To all whom it may concern.-

Be it known that I, MICHAEL FRANKLIN MY- ERS, of Arbuckle, in the Chickasaw Nation and Indian Territory, have invented certain new and useful Improvements in Break Pin Attachments for Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilledin the art to which it pertains to make and use it, reference being had to the accompanyingdrawings,which form part of this specification.

My invention relates to an improvement in break-pin attachments for plows; and it consists in the combination of the plowbeam and the pivoted sleeve,to which the plow is bolted, and which is provided with devices at its upper end for breaking or cutting the'pins, with the pin-holder, in which is placed a spring-actuated rod which presses the pins downward,and a spring-actuated block provided with a small separating device which separates the pin actually in use from the others above it, and which block prevents the pin in use from falling out or becoming displaced, as will be more fully described hereinafter.

The object of my invention is to provide-an attachment for the beams of plows whereby a number of break-pins are held in position ready for use, so that when one becomes broken another will at once take its place, and'thus prevent all necessity of the plowman stopping his team and driving out the broken pin for the purpose of replacing it by another.

Figure l is a side elevation of a break-pin attachment embodying my invention, shown partly in section. Fig. 2 is a perspective ofthe holding-block and the devices connected to the upper end of the sleeve.

A represents an ordinary plow-beam, to which the sleeve B is pivoted, and to which sleeve the plow or shovel is bolted inthe usual manner. Secured to the rear edge of the lower end of the plow-beam is the fiat metallic spring C, which bears against a pin or projection, D, which extends through the sleeve, and which spring returns the sleeve automatically to position after it has had its lower end forced backward by catching against some obstruction and breaking the break-pin.

All that the plowman has to do after the sleeve has broken the break-pin by catching against some obstruction is to raise the rear end of the plow-beam above the ground, so that the sleeve is left free to move, and this flat metallic spring will instantly return the sleeve to position. Secured to the upper rear corners of the sleeve are the two metallic plates or cutters F,whicli bear against the rear side of the break-pin G, and which plate or cutters break or cut the pin when the plow strikes against an obstruction. 'of the sleeve shall move backward is regulated both by the stop H, secured to the front edge of the sleeve and which catches against the front edge of the plow-beam, and the shoulders I, formed upon the lower end of the pin-holder.

- Thepin-holder J consists ofa suitable slotted frame or block, which is secured to the rear edge of the plow-beam, and which is provided with a slot, L, in which the supplemental pins are placed. Moving in this slot and bearing downward upon the tops of the break-pins is the spring-actuated follower N, which forces the pins downward,so that as fast as one becomes broken or injured the next succeeding one will instantly take its place. The lower pin rests upon the top of the spring-actuated block 0,

which is placed in the extreme lower end of the pin.-holder,and which moves at right angles to the spring-actuated follower. This block projects across the lower end of the slot or opening in the pin-holder, so as to catch under the break-pins and support them in position and against the downward pressure of the springactuated follower. Secured upon the upper part of this block is aseparating-pin,P, which serves to separate the lower pin from the one just above it,and which,when the pin in use is broken, serves to prevent the next pin above it from being crowded down before the broken parts have timeto be removed. The outer sides of this block 0 have inclined surfaces or shoulders a formed upon them, so that when the sleeve is forced back into position by the spring 0, after'apin has been broken, the cutters will strike against the inclined shoulders or flanges and force the blockbackward sufficiently far to allow a new pin to drop down into the recess or cut-away part formed in the upper front corner of the cutters. As the cutters force the block backward a pin drops down into the recess, and then the block carrying the separating-pin upon its top springs outward and again The distance the upper end separates the pin not in use from the one which is.

Whenever the plow or cultivator point strikes against an obstruction of any kind, the operator has only to raise the beam upward sufliciently far to allow the spring to operate upon the sleeve,\vhen the broken fragments of the old pin, which is cut into three parts, will be displaced and a new pin will drop into position ready for immediate use, thus enabling the plowing to proceed without the necessity of having to stop to put in a new pin.

Having thus described my invention, I claiml. The combination of the plow-beam, the pivoted sleeve connected thereto and provided with cutters for bearing against the break-pin, and a pin-holder containing one or more pins which are to take the place of the broken pin, substantially as shown.

2. The combination of a plow-beam, the sleeve pivoted thereto and provided with cutters to bear against the break-pin in use, a pinhoidcr connected to the plow-beam, a springaetuated follower for forcing the pins downward, and a support at the bottom of the holder for supporting the pin in use, substantially as described.

3. The combination of the plow-beam, the pivoted sleeve connected thereto and provided with cutters to bear against the breakpin in use, a slotted pin-holder, a support placed in the lower end of the pin-holder for supporting the break-pins not in use, aspring- 4. The combination of a plow-beam, a pivoted sleeve provided with cutters which bear against the break-pinin use,the'pin-holder,and a spring-actuated supporting-block placed in the lower end of the holder and provided with inclines or flanges, against which the cutters strike for the purpose of forcing the support backward and allowing another pin to drop into position, substantially as specified.

5. The combination of the plow-beam, the sleeve pivoted thereto and provided with cutters which bear against the pin in use, the pinholder, and a support which is placed in the lower end of the pin-holder and provided with a separator to divide thepin in use from those held in the pin-holder but not in use, substantially as shown.

6. The combination of the plow-beam, the pivoted sleeve connected thereto and provided with notched cutters to catch the pin in use, the pin-holder, the spring-actuated follower, the supporting-block in the lower part of the pin-holder, and the spring for returning the spring to position, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

MICHAEL FRANKLIN MYERS.
