SGISSORS.

Specification of Letters Patent.

Patented Dec. '7, 1915.

Application filed August 21, 1915. Serial No. 46,746.

To all whom it may concern:

Be it known that I, ALBERT MA'rtrsoN, a subject of the King of Sweden, residing at (lured, Krokstad, Sweden, have invented certain new and useful Improvements in Scissors, of which the following is a specification.

The present invention relates to scissors and more particularly to such as are used by barbers. I

T he invention resides in an improvement in such scissors which makes it possible to vary, at will and without any special adjustments, the number of cuts of the blades for each closing of the handles. The advantage of this construction will readily be understood, as cutting with these scissors is less tiring for the operator than when 4 using ordinary scissors.

One embodiment of the present invention is illustrated in the accompanying drawing where Figure 1 shows a plan view of the scissors closed; Fig. 2 is a similar view with the scissors open; Fig. 3 is a side view of Fig. 1 partly in section, and Fig. l is a ratchet wheel having a greater number of teeth to what has been shown in Figs. 1 and 2.

The scissors have a short blade 10 and a long one 11 which are journaled by means of a pin or screw 12 secured in the long blade. Attached to the screw at one end and to the short blade 10 at the other end 13 is a spiral or other suitably-shaped spring 13, which tends to close the blades. The continuation of the large blade forms one handle with loops 23, while a short handle with a loop 22 is fulcrumed on a journal 18 threaded in the long handle. On the same journal. is mounted to revolve, a ratchet member having teeth 15 meshing with a tooth 14.- formed on the rear end of the short blade 10. This ratchet member is also pro- \ided with another set of teeth 16 011 a smaller diameter and facing in opposite direction to teeth 15.

The connection between the hub part 17 and the short handle and loop 22, is offset, so that the shoulder formed is facing the teeth 16. In a recess 21 in this handle a plunger 19 actuated by a compression spring 20 is mounted to slide radially and engage with the teeth 16. There may be the same number of teeth 15 as teeth 16 or there may be more of the teeth 15, but always an exact multiple thereof depending on how small or large strokes are required, and the ratchet member may therefore be made exchangeable and two or three with different num ber of teeth may be supplied with each. pair of scissors.

As illustrated in the accompanying drawing, the same number of teeth 15 and 16 are provided. To vary the number of strokes of the blades, the handles will then have to be opened a different amount. If for instance, the handle is opened only slightly so that the plunger only passes over one tooth 16, then, upon closing the handle, the plunger will turn the ratchet member in the direction of the arrow 11 and the short blade will be forced open once by a tooth 16 as seen in Fig. If on the other hand, the handle 22 has been opened far enough for the plunger to pass two teeth 16, then, upon again closing the handle, the blade will be opened and closed twice. It is obvious that the tooth 14 serves as a stop to hold the ratchet member from turning during the opening of the handle.

While the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

YVhat I claim as new is 1. In a pair of scissors, a blade with a, rigid handle, a short blade journaled thereon, a short handle also journaled on the first blade and handle, and means interposed be tween. said short handle and short blade for opening and closing said short blade upon closing said short handle, said means comprising a pawl and ratchet device ournaled coaxially with and actuated by said short handle, a second ratchet device connected to the first and constructed to actuate said short blade.

2. In a pair of scissors, a blade with a rigid handle, a short blade journaled thereon, a short handle also journaled on the first blade and handle, a ratchet member mounted coaxially with said short handle, and having two sets of teeth facing in opposite directions, a spring actuated pawl in said short handle engaging with one set of said teeth for turning said member upon the closing of the short handle, said second set of teeth engaging with said short blade to open'it and separate means tending to close the blade.

3. 111 a pair of scissors, a blade with a rigid handle, a short blade journaled thereon, a short handle also journaled on the first blade and handle, a ratchet member mounted coaxially with said short handle, and having two sets of teeth facing in opposite directions, a spring actuated pawl in said short handle engaging with one set of said teeth for turning said member upon'the closing of the short handle, said second set of teeth engaging with said short blade to'open it and separate means tending to close the blade, the number of said second set of teeth being a. multiple of that of the first set of teeth, whereby said short blade will be made to open and close several times while the short handle is being closed once.

4. In a pair of scissors, a blade with a rigid handle, a short blade journaled thereon, a short handle also journaled on the first blade and handle, a ratchet member mounted coaxially with said short handle, and having two sets of teeth facing in opposite directions, a spring actuated pawl in said short handle engaging with one set of said teeth for turning said member upon the closing of the short handle; said short blade being provided with a tooth meshing with said second set of teeth and preventing any reverse turning of said member, a spring tending to close the short blade, said ratchet member on being revolved by said short handle opening said short for turning said member upon the closing of the short handle; said short blade being provided with a tooth meshing with said second set of teeth and preventing any reverse turning of said member, a spring tending to close the short blade, said ratchet member on being revolved by said short handle opening said short blade, a plurality of times for each closing of the short handle.

In testimony whereof I al'lix my signature.
