carrying spindle.

Be it known'that I, JOHN J. MEEHAN,

citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Razor-Stroppers; and I do declare the following to be a full, clear, and exact description of the invention, such as willv enable others skilled in the art to which it appertains to make and use the same, reference, being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in razor stroppers, being more especially intended for use in sharpening double-edged blades, though it may be employed with other blades, if desired. 7

My present invention may be considered an improvement over the construction set forth in United States Letters Patent N 0. 942,731, dated December 7th, 1909.

y present invention relates more particularly to the means for rocking the bladecarry'ing device as the strop is pulled back and forth over a rocking member, or in engagement therewith. 'This rocking member is rigidly connected with an arm which is pivotally connected with another arm which is in turn rigidly connected with a blade- The strop preferably engages a pair of pins or rods which are connected with the rocking member on opposite sides of a plane passing centrally through the device parallel with the sides of the frame. As the strop is pulled in one direction, it exerts a leverage on the side of the rocking member where the pull is exerted, thus making the rocking action very sensitive, the said action being communicated to the blade-carrying spindle.

Having briefly outlined my improved freely thereon.

-Fig. 3is a side elevation of the same looking in the direction of arrow 3, Fig. 1. Fig. 4 is a view looking in thedirection of arrow 4, Fig. 1, the strop members being broken away below the frame. Fig. 5 is a section taken on the line 5-5, Fig. 1. Fig. 6 is a similar section, showing the rocking member turned to its limit of movement in onedirection whereby the edges of the doubleedged blade are caused to engage the runs of the strop on opposite sides. Fig. 7 is a similar View showmg axslightly modified form of construction, or rather a modified form of use, since in this case the strop engages the rocking device at the top while in the other forms of construction the strop engages the pinsbelow the top or housing of the rocking device. Fi 8 is a side view of the blade-carrying spin le or the device into which the blade-holder is inserted, prepara-- tory to beginning the sharpening operation. This is a View looking in the direction of arrow 8, Fig. 9. Fig. 9 is an edge view of "the same, or a view looking in the direction of arrow- 9, Fig. 8. Fig. 10 is a top plan view of the blade-holder. Fig. 11 is an edge viewof the same. Fig. 12 is a-plan view of a double-edged blade .of the Gillette type. Fig. 13 is a plan view showing the blade applied to the blade holder.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a, casing closed on opposite sides, as shown at 6. This casing is cut away at the sides above the members 6. The-latter are, however, connected at their ends as shown at 7. These ends of the casing havev upward extensions 8 in which is trunnioned a rocking frame 9 having depending members 10 provided with trunnions 12 which are journaled in the end extensions 8 of the casing. In the depending members 10 of the rocking frame,

are mounted two bearing pins 13 locatedon opposite sides of the trunnions. These bearing pins may consist of small spindles 14 and sleeves or rollers 15 mounted to turn The'spindles 14 may be either journaled or fast in the end members 10 of the rocking frame. If the parts 15 are mounted to turn freely, it reduces the friction between the strop 16 and the bearing parts.

bers 10, as heretofore explained. The casing extensions 8 project above the trunnions 12 of the rocking member and a spacing-bar 18 has. its ends pivoted as shown at 19 in the upper extremities of the extensions 8. Short chains or flexible devices 20 are connected with apertured lugs 21 with which the spacing-bar 18 is provided. The opposite extremities of these chains are connected with a ring 2 which may be connected with a nail, a stationary hook, or any suitable stationary device aifordin the necessary resistance during the stropping operation. At one extremity of the rocking member 9, the trunnion 12 is provided with an extension 12 with which is rigidly connected one extremity of an arm 22 which projects clownwardly parallel with the end of the casing, its lower extremity being pivotally connected as shown at 23 with a short arm 24, the latter being secured b means of a screw 25 to one extremity 26 o a rock-spindle 27. The hub ,28 of this spindleis. slotted as shown at 29 to receive the short arm 24,

which together with its companion arm 22 forms a sort of toggle, whereby the rocking movement is transmitted from the member 9 to the member 27. 1 By virtue of the recess 'or slot 29, it becomes practicable to secure the short arm 24 in proper operative relation with the hollowspindle. This spindle is slotted as shown at 30, the slot being open at one end as shown at 31, to receive a blade-.

' holder 32 which is adapted to be inserted endwise into the hollow spindle. This blade-holder 32 is provided With short lugs 33 adapted to enter openings 34 formed in a blade 35 which as shown in the drawing is of the Gillette type, having edges 36.

Preparatory to using the device, the blade-holder 32 is withdrawn from the rock spindle 27, the parts being originally in the position shown' in Fig. 1. The blade is then applied to the holder as shown in .Fig. 13,

after which the blade and holder are in-,.

serted endwise through slot 38, formed in" one end of the casing. The device is then ready for use, it being assumedthat the stro 16 has been threaded through the rocking member 9 below the cap 17 and engaging the pins 13. Then as the opposite bein extremities of the strop are alternately pulled toward the user, a rocking movement is imparted to the device 9, which movement is transmitted through the toggle members 22 and 24, to the rock-spindle 27 to which are imparted partial rotations inreverse directions, wherebythe edges of the blade are alternately thrown into engagement with the ad'ac'ent surfaces of the strop, whereby both edges of the blade are being simultaneously engaged by the strop, but on opposite sides. It will "be understood that the rocking movement of the spindle 27, always has a 1 rection the reverse of that of the member 9 but the rocking-action is simultaneously imparted to both members,to the member 9 directly by the action of the strop, and to the member 27 through the medium of the toggle.

In the form of construction shown in Fig. 7, the strop is passed over the cap 17 of the rocking member 9, care being taken to leave 7 room enough for this purpose, below the spacing bar 18. The opposite extremities of the strop 16 are preferably provided with metal loops 37 which are connected with the strop members proper by means of clasps 39,

each consisting of a plate 40 connected with theloop as shown at 41. Each plate has a clas 42 pivoted in the ends 43 of the plate as s own at 44. When it is desired to detach the loops 37, it is only necessary to raise the clasp 42. When it is desired to secure the elasps to, the extremities of the strop, the latter is passed between the members of the clasp after which the latter is pressed inwardly in the same manner as a suspender clasp.-
