Application March 22, 1943, Serial No. 480,124

- 4 Claims. (Cl. 226-41) This invention relates to an electric cutting and cleaning device, particularly to cutting and cleaning waste thread ends of newly finished garments in the factory production, which is now done by hand scissors. I

The main object of this invention, is to provide safety means to speed up the work and also to avoid cutting or injuring the cloth or garment which now occurs with hand scissors, but will not happen with this invention, as the lower cutting eiement is provided with cutting teeth or blades having ball end portions that smoothly 'run on and over the cloth of the garment and nut that'interlocks the two cutter elements in their operative positions, the upper or intermediate cutter element being reciprocative back and forth by an eccentric drive from the drive shaft of a small motor embodied .with a handle member that is secured onto the extended upright portions of the'lower cutter element. A switch bar is provided lengthwise of the handle for manipulating whenever desired in the cutting operation of this device.

Another important object of this invention, is the adaptability of using thiscutting device in any direction, as there are two cutting edges, front and rear, so the operator may move it back and forth without turning his hand, however, it i is possible that only one edge or row of cutting teeth or blades will be serviceable in many ways, and if so, a single cutter device may be made as well as the double cutter device shown in the drawing, or a safety guard may be placed over one row of teeth which may be reserved for later on when other row of teeth become slightly dull.

However, the assembled parts are readily disassembled for the sharpening of the teeth and blades, and quickly reassembled.

Another object of this invention, is the compactness of this cutter device which is handily carried in the pocket when not in use, and may be used in many other useful ways other than cutting and trimming free thread ends, and the like, from garment being made.

Other objects of this invention, will appear as the description proceeds in the following specifie cation, accompanied by the annexed drawing, in which Figure 1 is a perspective view of the cutter device of this invention.

Figure 2 is a longitudinal elevational view of the same device. Y

Figure 3 is a cross-sectional'view on line 3--3 of Figure 2.

Figures 4, 5 and 6 are perspective views of the three major parts or elements of this invention.

Figure 7 is a lengthwise elevational view of the bottom or lower cutter or scissor element.

Figure 8 is a sectional view on line 8-8 of Figure 2. I I

Referring to the drawing, the numeral I 0 indicates a bottom or lower cutter element, also to be known as the lower scissor element, having a double edge or row of cutting teeth or blades ll provided with ball end portions I la. An upper track portion I 2 connects to uprights or threaded extensions l3, having a slotted opening or gap l4 therebetween and an inwardly concaved portion I 4a and recesses l5. These uprights have threaded portion l5 and shoulder portion l1 terminating into semisleeve-like extensions lGa, that are adapted to be secured into a handle member, later to be described. 1

In Figure 5 is shown the upper cutter element 20 having teeth or blades 2| extending from the bar portions 22 formed integrally with a bridge portion 23 provided with a slotted opening 24 transverselythereof. This cutter element is adapted to be placed onto the lower cutter element Ill, whereby the bridge portion 23 is insertable through the gap M to be seated on the lower cutter element I0, where it is slidable into the recesses I5 by means of an eccentric drive, later to be described.

In Figures 2 and 8, the cutter elements I 0 an 20 are shown interlocked by a plate member or cover plate 39 having a swivel connection with a knurled nut or ferrule 3|, having an inner threaded portion 32 that is screwed onto the threaded portions I6 of the uprights l3 of the lower stationary cutter element Hi, this knurled nut3l being locked by a set-screw 3m in its adjusted position for the reciprocating movement of the intermediate cutter element 20 now interlocked between the cover plate 30 and lower cutter element I ll.

The extensions lfia of the uprights l3 are adapted to be secured into a handle member composed of split halves 36 and 31, within which a small motor M may be embodied, having connections to -a bar-like switch 38 which is easily manipulative as shown and illustrated in Figure 1. Screws or bolts 39 may secure the halves 36 and 3'! onto the extensions l6a, in which a rubber or suitable washer W may be inserted onto the knurled nut 3|, so to make the connection dust proof. 1

The motor M is connected to any suitable source of electric current supply through a cord C, the motor having an extended drive shaft S onto which may be secured a collar or member 40 having a pin 41 eccentrically arranged therein, the pin 4| being engageable into the slotted opening 24, and imparts a reciprocating movement to the intermediate and uppercutter element 2!) during the rotary driving operation of the shaft S, so the teeth or blades 2| move over the stationary teeth or blades ll, thereby pro.- viding a multiple scissor cutting means by the flat or straight contacting portions 25 and 28,

thedrawing, and hereinbefore described, illustrates the objects of this invention clearly, but it is obvious that this or any improvement may be adopted, and therefore, reserve that right, providing same comes within the scope of the appended claims.

Having thus described our invention, what we claim as new and desire to secure by'Letters Patent of the United States of America is as follows:
