lt will therefore be seen that according to the present invention there has been provided a combination hair clipper which is an improvement over prior devices as for example the present invention is an improvement over the combination hair clipper shown and described in prior Patent 2,946,123, dated July 26, 1960. According to the present invention it will be seen that the clippers 20 are adapted to be connected to a suitable source of electrical energy as for example the conductor 25 can connect the motor 23 to the source of electrical energy, and with the switch 26 turned on the motor 23 will operate to rotate the shaft '27 and this in turn will rotate the fans 28 in the chamber 34. With the cover 83 in closed position it will be seen that vacuum pressure will be created by the rotation of the fans 28 so that hair that is cut by the mechanism 64 will be sucked into the opening or port 96 and this hair Will travel through the passageway 97 and be received in a compartment 47. The screen 37 will prevent the hair from travelling beyond the compartment 47, but the air will be able to travel through the screen 37 so that this air can tlow through the screen 37 and then into the chamber 34 and then through spaces around the motor 23 whereby the motor 23 can be kept cool as it operates, and this air can flow out through the left end of the housing 21, FIGURE l, after it has performed its cooling action on the motor 23, and this air is adapted to travel through passageways or spaces as indicated by the numeral 24 in FIGURE 1 during the cooling of the motor 23. This action takes place when the cover 83 is in closed position, and the catch 87 includes an end portion 93 that is adapted to engage an edge portion 94 of the cover 83 to maintain the cover 83 in closed position relative to the compartment 47. The spring 91 exerts pressure on the catch 87 so that the catch 87 will not inadvertently move out of holding engagement with respect to the cover 83. However When it is desired to open the cover 83, finger pressure can be applied to the button portion 88 to compress the spring 91 whereby the catch 87 can pivot onits pin 90 in order to permit the end portion 93 to move out of engagement with the edge 94 so that the cover 83 can be swung open on its hinge 84. When the cover 83 is in closed position, its

projection 85 is in closing or blocking relation with respect to the opening 86.

At the same time that the motor 23 is operating the fans 28, it is providing a source of power for the cutting mechanism 64 and this is because of the previously described arrangement of parts. That is, as the shaft 27 rotates due to actuation of the lmotor 23, the worm 29 will turn so as to rotate the gear 30 which is in meshing engagement with the worm 29, and since the gear 30 is iixedly mounted on the stub shaft 31, it will be seen that the stub shaft 31 will rotate, and with the cam 32 on the stub shaft 31, it will be seen that this will cause an eccentrical movement of the cam 32. The actuator 53 includes the arm 54 which has its slotted portion 55 engaging the cam 32, so as the cam 32 travels eccentrically the arm 54 of the actuator 53 will be moved in a direction to correspond to the eccentric movement of the cam 32 whereby the ar-m 54 can move about an axis extending through the screw 57. As the arm 54 moves it causes corresponding movement of the block 59 since the block 59 is secured as at 60 to the transverse end portion 56 of the arm 54. The pin 105 acts as a fulcrum or pivot for the block 59 and its associated parts, and with the nger 61 secured as at 62 to the block 59, it will be seen that this movement of the actuator 53 will cause corresponding movement of the linger 61. In view of the fact that the groove 63 of the linger 61 receives or engages the projection 72 on the member 71, it will be seen that as the finger 61 moves back and forth, it will cause corresponding back and forth movement of the member 71 due to the interengagement of the parts 63 and 72, and since the member 71 is connected as at 73, to the movable cutter member 74, it will be seen that this action will result in back and forth movement of the cutter member 74 relative to the stationary base element 66 so that the teeth 75 and 67 can coact to cut or severe the hair therebetween. This cut 4hair is sucked up by the vacuum created pressureand sucked into the port 96 whereby the cut hair travels through the passageways 97 and is received in the compartment 47 as previously stated.

The user can readily look through the window 95 which is adapted to be made of a suitable transparent material such as glass, transparent plastic or the like, so that the user can readily observe when the compartment 47 needs to be emptied. When it is desired to empty the compartment 47, it is only necessary to open the catch 87 by applying linger pressure to the button 88 so as tomove the end portion out of engagement with the edge 94 whereby the cover 83 can be swung open on its hinge 84. As the cover 83 is moved to the opened position, the flow of air will travel in such a manner or direction so as to -blow out or cause the hair in the compartment 47 to be discharged from the compartment 47. When the cover 83 moves to an open position, the projection 85 exposes or opens the hole or opening 86.

The support element 76 is held in place by the pin 78, and the spring 79 helps to exert suflicient pressure on the pin 78 so that the pin 78 can exert the desired holding action on the support element 76.

The use of the worm gear 29 and the worm wheel 30 between the fan or fans 28 and the eccentric or cam 32 permits heavy work to be performed without increasing motor horsepower, and these gears can be enclosed for lubrication purposes or they can be left open and lubricated with graphite.

With the present invention the hair can be removed automatically from the container by using part or all of the exhaust air from the fan or fans instead of using a reversible motor. In order to use the exhaust air to remove the hair, the cover or lid 83 is opened and the shutter 43 is moved to closed position relative to the cutaway portion 36, relieving the Vacuum in the compartment 47, removing the closure 1 from the opening or aperture 100, and, at the same time, removing the stopper 85 from the opening 86 thus permitting the air to ow in through the opening 86, under and bypassing the compartment 47, into the chamber 34 where part of it is deflected by the fans radially outwardly into the aperture 99, through the duct 98, through the aperture 100 and into the compartment 47 where the air strikes the baffle 48 and removes the hair from the compartment 47 as shown in FIGURE 8. The portion of the air not deflected by the fans into the aperture 99 is forced out the back of the clipper, passing through and around the motor. The closure 101 is secured to or formed integral with the cover 83 so that anytime the lid or cover 83 is open, the intake cover or closure 101 is likewise removed from blocking the aperture 100.

To remove the hair from the container or compartment 47, the cover or lid 83 is opened, and the shutter 43 automatically moves to closed position relative to the cutout 36 relieving the vacuum in the compartment 47. This action takes place automatically because the shutter 43 is spring loaded. That is to provide the spring loading for the shutter 43, the spring 40 is fastened to the rod 39 that operates the shutter, and this mechanism is loaded so as to close the shutter when the lid or cover 83 is opened. Since the rod 39 engages the cover 83, the cover is kept closed by the spring loaded catch 87 which may have a suitable construction, and the cover is kept closed when the clipper is being operated or used in the usual manner.

With further reference to the cutting mechanism 64, due to the provision of the pin 78 and spring 79 as Well as the support element 76 and its associated parts, the cutting mechanism64 can be readily removed or disconnected from the housing when desired or required. rl`he device is constructed so that the various parts can be readily disassembled in order to permit cleaning or repair or replacement thereof. The entire cover may be made of transparent material insteadv of just having the small window of transparent material if desired or required.

As previously stated the exhaust air flows through and around the motor 23 so as to cool the motor as the hair is being cut.

Minor changes in shape, size and rearrangement of details coming within the scope of the invention claimed may be resorted to in actual practice, if desired.
