UNITED STATES MARCUS CB. BEHRMAN, OF NEW PATENT OFFICE.
I YORK, N. Y., ASSIGNOR TO THE LOX SEAL CORPORA- TION, OF BROOKLYN, NEW YORK, CORPORATION 01 NEWIYORK.
FILE-WIRE CUTTER.
Application blades in the form of flexible wafers, and to.
provide the blade holders'with suitable means for properly positioning and holding the bladesandat the same time permitting ready removal thereof. a
It is one of the objects of the present invention to provide means in association with the blade holder for facilitating the insertion and-removalof blades, and for assuring firm retention of theblade after it has beenplaced into use. V
I In, accordance with my invention, the means for firmly retaining association with the pile wire comprises generally members which engage opposite ends of the blade and co-operate not only to assure the blade of a predetermined position in its association with the holder and of its but also permits of its ready insertion and removal. 7 Where I have used blade holders which comprise channel portions for receiving the blades, I have found it desirable to plug or block portions of the channel for the purose of forming a recess? into which an end of the blade may be inserted. Itis an object of the present invention to accomplish this purpose by means ofv a construction time inexpensive, simple and eficient. I Y f V In accordance with this object of the invention, I contemplate forcing portions of the channel walls inwardly in accordance with .a predetermined plan, thereby providing portions which are suitably disposed to the desired function. More particularly, the inward projections in the one case, and the plug in the other, are so arranged and constructed as to provide an overhanging end portion or wall beneath which an endoof the cutting blade may be inserted. I
Another object of my invention is the pro; vision of a means for engaging the opposite end of the blade, in the form of a finger or projection so constructed and positioned as the blade in its filed December 8, 1926. Serial H 0. 152,738.
to ermit the blade to be readily inserted an when the blade is inserted to actas a lock for the blade to prevent its removal.
For the attainment of the foregoing obects and such other objects as may hereinafter appear or be pointed out, I have illustrated my invention in the accompanying drawings in which:
Figure 1 is a side elevational view of my holder showing the blade in position;
Figure 2 is a top plan View of Figure 1; F1 ure 3 is a vertical section on line 3-3 of Figure 1;
Figures 4 and 5 are respectively a vertical longitudinal section and a top plan view of.
another embodiment.
Referringv to the drawings,
, it W111 be bi served thatI have shown -a blade holder 10 having a forward enlarged spoon portion 11, the purpose-of which will be wellknown to those skilled in the art. The blade holder shown is of the type which is constructed of a substantially fiat'blank doubled-over along a longitudinal line 12 "to form a U- shaped blade receiving channel 18.
The blade whichI prefer to use is of the fiBXlblB wafer type having a bottom edge 14,, a cutting edge 15 disposed at an angle to the edge 14, and a forward edge 16 which completes a generally triangular figure. The blade is associated with a holder by positioning its rear end, or foot 17, under an overhanging wall of the character her-einbefore referred to; The other end 16 is constructed in a manner which permits co-op- .eration thereof with a suitable tab 18 pro vided on the spoon portion 11. More particularly, this tab 18 is struck up out of the spoon portion nel and it comprises a lower edge 19, forward and rear edges 20 and21 respectively, each of the edges 19, 20 and 21 having been formed by cutting proper slits through the spoon portion 11. Itwill be observed that two of the edges are formed by vertical or substantially vertical cuts and the opposite edge by a horizontal cut connecting the two vertical cuts The out which forms the'inner edge 21 is illustrated in the drawings as slightly inclined for purposes that will be understood as the assembly of the knife with the holder is explained.
Upon viewing the drawings,it will be observed that I have illustrated the end of the blade 16 as provided with a cut-out .por-
ll'into the path of the chantion which provides a wall 22 parallel'to but offset with respect to the edge 16 and a connecting wall 23 substantially parallel to the edge 14. After the foot 17 of the blade has been properly positioned, as will iereinafter be described, the blade is moved downwardly into position to its seat in (the channel and in so doing, the portion of the blade beneath the connecting wall 23 will be flexed so that the end 16 will spring into place beneath the tab 18. More particularly, the edge 23 will be caught by the bottom slit 19 while the edge 23 will encounter the edge 21 and prevent upward movement of the blade after it has been positioned.
I shall now describe the construction which permits engagement of the foot 17. or the blade. The general purpose is to pro- Vide an overhanging wall 2 1 beneath which the foot may rest. This overhanging wall assumes a general direction extending from the rear base of the channel upwardly and forwardly to the open end of the channel.
In Figures 1 and 2, I show one method of providing the overhanging wall. In this form I provide the inwardly directed portions 27 and 28, which are illustrated as produced by striking up the walls of the channel. These projections are provided on the opposite walls of the channel, and they are so positioned as to constitute a composite overhanging portion or wall. More particula y, the project-ion 27 may be struck up fi'OiT-Ll one wall 01" the channel, whereas the projection 28 1nay be struck up from the ther. The projections are preferably elon gated'and are shown as arranged along parallel lines which are at an angle to the chan nel axis The projections are of sufiicient magnitude to overlap each other transversely with respect to the channel. In this way, a positive blade stop is provided, it being impossible for the blade to pass more than one of the projections, ii any. The projections are also arranged to overlap each other longitudinally with respect to each other. I have found it necessary to do this because of the extreme diiiculty or providing a substantially elongated projection in the very small space which a renders available.
These projections 27 and 28 are so disposed with respect to the angularity of the standardized blade, that the blade can ac suine only one position within the holder. If the blade assumes a position toward one side of the channel, it will encounter the stop 28; it it assumes a position along the other side of the channel, it will encounter the stop 27. The points of encounter may, of
course, be difierent points. That is, the point 29 of the blade edge may encounter the stop 28, while the point 30 will encounter the stop 27. Thus, even if the channel should eventually spread, as it frequently pile wire oi": usual sizeup elongated pro ections out oi registry with does, the blade will still be positively ongaged, regardless of the play which it may have within the channel.
In Figure l I have illustrated amodified form wherein projections 31 and 32 are arranged along one line, i. e., they do not dersobvious the overlapping of the projections ina transverse direction, and it will be understood that this overlapping. is illustrative of that which occurs in the construction illustrated in Figure 2.
The purpose of the inclined wall21 will be understood in connection with F ig. 1 where the finger or tab 18 is shown as forced upwardly or outwardly to a sufiicient extent topermit the wall 22 of the blade to work beneath the wall 21, thus giving a slight play to the blade and preventing any flexing of the blade outwardly.
It will be obvious that various changes in the details herein described and illustrated for the purpose of explaining the nature of my invention may be made by those skilled in the art without departing from the spirit and scope of the invention as expressed in the appended claims. It is therefore intended that these details'be interpreted as illustrative, and not in a limiting sense.
Having thus describedmy invention and illustrated its use, what I claim as new'and desire to secure by Letters Patent is:
1. A pile wire cutter comprising a blade holder having a' U-shaped channel, portions of the channel walls having inwardly forced portions-positioned so as -to form steps bencth and againstwhich anend of a blade may be made to rest.
2. ii pile wire cutter comprising a channeled blade holder, the walls adjacent to one end of the "channel having inwardly struckeach other longitudinally of the holder which are disposed along lines angular with respect to the channel axis.
5. A pile wire cutter comprising a channeled blade holder,- the side walls adjacent -to one end of the channel beingprovided with internal elongated projections disposed along parallel lines atan angle to the channel axis and disposed longitudinally of each other and positioned to constitute a composite overhanging end wall for the channel beneath which an end of a blade may be made torest.
5. A pile wire cutter comprising ablade holder having a U-shaped channel, portions of the channel walls having inwardly struck up portions positioned so as to form steps beneath and against which an end'of a blade may be made to rest, and said struck-up portions being of a magnitude to overlap each other transversely of the channel.
6. A pile wire cutter comprising a blade holder having a channel, portions of the posite channel walls having inward projections positioned to form blade stops, and
said projections overlappingv each other transversely of the channel whereby a blade which does not encounter one thereof will be made to encounter another.
7. A pile wire cutter comprising a blade holder having a channel, portions of the 0pposite channel walls having elongated inward projections arranged along parallel lines and positioned to form blade stops, and said projections overlapping each other longitudinally with respect to each other, and transversely with respect to the channel, whereby a blade which passes one thereof will positively encounter another.
In witness whereof, I have hereunto signed my name.
