causeway To all whom itmag concern: 1 I
Be it known that I, EDWARD Enronson, a subject of theK ing of :Swed'emand. a resident of Lynn, in the county of Essex and State of lilassachusetts, have invented certain new and useful Improvements in MovableGuards for Sewing-Machines, of which the following is a specification.
This invention relates to sole sewing machines and particularly to means for protecting the work from being injured or soiled during theoperationof the machine,
' and has for its object the provision of means for protectingthe workfrom the operating parts of the machine. I a
This inventionbonsists in providing the awl supporting member with a guard adapted to be moved laterally therewith 'in contact with the front face of the work support during the feeding operation.
The invention further consists in certain novel features or "construction and arrangement of parts which will be fully understood by reference to the description of the drawings and to the claims hereinafter given.
Of the drawings: Figure 1 represents a front view of a machine embodying the principles of the present invention, and Fig. 2 represents a vertical section of the same, looking to theright of Fig. 1.
Similar characters designate like parts throughout the figures of the drawings.
The invention is illustratedas applied to a sole-sewing machine similar to that shown and described in application filed by. Lawrence E. Johnson and myself, May 19, 1913, Ser. No. 768,671, to which reference may be made for the complete operation of the machine.
In the drawings 20 is the base of the ma chine adapted to be secured to a column and having the end frames 21 and 22 provided with bearings for a revoluble shaft 23. The revoluble shaft 23has the driving, wheel 24 secured to one end thereof, while to its opposite end is keyed the cam disk 25. Interposed between the side frames 21 and 22 and keyed to the shaft23 is the cam disk 27. The cam disks 25 and 27 are adapted to operate various mechanisms necessary for the proper operation of the machine, all of which have been fully illustrated and described in the application 768,671, hereinbe sp i va ion of etter a n Application filed July 20, 1914. Serial No. 852,102.
, MOVABLE en ma R SEWING-MACHINES- Pate Aue- 1 1915- nisms form no part of the present invention they are not herein described.
To the innerside of the side frame 21 is secured the work support 28 which may be of any well-known construction. The side frame21 has also formed upon its inner face a race 30' for the shuttle 81 which is driven in any well-known manner. The frame 22 is provided with two bearings in which reciprocate two parallel studs or pins 61 mounted upon 'a movable frame 62. This frame haspivoted to the lower end thereof at 63 an oscillating slotted lever 64:, the lower end of which is provided with a roller 65 extending into a cam path 66 in the periphery: of thercam disk 27 In the slot 67 of the lever 64 is a fulcrum block 68 pivotally mounted in'a forked member 69 having a shank 70 extending through a straight slot 71 in the frame 22, and also through a slot 72 in ahand lever 73 pivoted at 74 to the end fra1ne 22. It is obvious that when the the free movement of the forked member 69 "lengthwise of the lever 64: without binding thereon. By means of the handle 63 the position of the fulcrum block 68 may be changed at will to secure any desired degree of speed. The frame 62 has mounted thereon the shaft 80 carrying the needle guide 88. Rotatable about the axis of the shaft 80 is a needle support carrying the needle 84. The needle support 85 has a gear segment 86 formed thereon through which oscillatory movement may be imparted to the needle and the awl 91 also secured to said needle support 85. The machine is also provided with the looper 126 operated by suitable mechanisms which form no part of the present invention. The needle and awl support move laterally with the frame 62 and when the awl is in the work the said a leaves the work the frame 62 is returned to its normal position before the awl again moves forward to pierce the work.
Secured to the' frame 62 is a guard 100 which 'is curved outwardly and in front of the work support 28 as is clearly indicated in Figs. 1 andv2 of the drawings. When the frame 62 is moved laterally to feed the j work the guard 100 is interposed between the work and the work support andmoves with thelatter, thereby preventing the work from being injured by contact with the work support and also keeping the work out of the path of the operating parts of the machine adjacent thereto such as the looper 126, the awl 91, and the needle 84.
This guard constructedas shown and described not only prevents the work from being injured or soiled but also prevents the workfrom assuming such a position as to interfere with the operation of themachine. Byproviding a guard of this characterand attaching it to the work feeding devices the feedingvof the work is greatly facilitated, as during the feeding operation the work would be free from frictional "contact with any stationary part of the machine.
It is believed that the operation and many advantages of a guard of the character described will be fullyapparent without fur- 1 Copies of this patent may be obtained for ther description.
Having thus described my invention, I claim:
1. In a sole-sewing machine, the combination of a work supportf needle and awl actuating mechanism; a member movable horizontally to feed the work on said sup port; and a guard secured to said member and movable therewith to protect the work during the operation of the machine,

In a sole-sewing machine, the combination of ajwork support; needle and awl actuating mechanism; a 'memberi'movable horizontally to feed the work onsaid support; and a guard secured to said member and movable therewith in contact with the front face of the worksupport to protect the work during the operation of the machine.
