This invention relates to a tool for applying a binding strip to the ed e of a panel and more particularly to a too for app ying a channel shaped rubber binding strip to the edge of a glass window panel for an automobile body, and has for its principal object the provlsion of a tool by means of which the binding strip may be quickly and firmly secured upon the edge of the panel and which at the same time will protect the hands of the operator from injury due to contact with sharp portions of the panel edge.

It is a further object to provide a tool of the character described that is light in weight and so formed as to fit comfortably into the h hands of the operator so that it will not produce discomfort or undue fatigue.

It is also an object of the invention to provide a device of the character described that is simple in construction, easy and economical to manufacture, and which will not readily get out of order in use.

Other objects and advantages will appear as the description proceeds.

In the accompanying drawings, there is illustrated one mechanical embodiment of the device of the invention per se, and also an embodiment showing a strip cutting and stapling device attached to the tool. The drawings, however, are to be taken as illustrative only and the scope of the invention is to be limited solely by the scope of the subjoined claims.

In the drawings:

Figure 4 is a sectional view on the line 44 of Figure 3.

Figure 5 is a perspective view of a short section of the binding material which this devicle is adapted to apply to the edge of a pane Figure 6 is a top plan view of a somewhat modified form of the device of the invention showing a strip cutting device and a stapling device ap lied thereto.

Figure is an elevational view of the modifiedsform of the device illustrated in Figure Referring to the drawings in detail, Figure 1 illustrates the ap lication of the device of the invention. In this figure, the numeral 10 generally indicates a panel such as a glass window panel for a vehicle body. The numeral 12 generally indicates a stri of binding material usually formed of ru her, which is applied to the edge of the glass panel to form a protective covering for the sharp, rough edges of the panel, and also to provide a weatherbead for the anel when the panel is mounted in a vehicle ody to prevent water from passing into the body between the panel and its su port.

The form of this rubber inding is particularly illustrated in Figure 5, and comprises a channel shaped member having a web portion 13 and two

flange portions

14 and 15 enclosing a slot which is adapted to receive the edge of the glass panel. It will be noted that the free edges of the

flange portions

14 and 15 are closer to ether than the portions of the flanges WlllCh are attached to the web 13, thus making it necessary to spread the flange portions apart before thelstrip can be pressed u n the panel. This operation has formerly en done en-v tirely by hand, the panel 10 bein placed upon a bench B and inserted in t e guide G The flange members were then separated by the forefingers of the operator and the binding forced upon the edge of the panel with the thumbs. As the binding was placed upon the panel, it was stretched by the operator and the panel turned to different positions until the binding had been placed entirely around it. The over-lapping portion of the binding was then cut. off and a staple driven into the binding to hold the ends together.

That part of the o eration which comprises inserting the bin ing upon the ed of the panel was found to be slow and t one and also a fruitful source of minor injuries ticularly dangerous, they would cause the operators on this particular operation to lose a considerable amount of time, thereby rendering the operation more expensive than it should be, as well as causing a considerable amount of discomfort to the operators. The device which forms the subject matter of this invention was designed to obviate this condition.

Referring to Figure 2, the numeral 18 indicates a tubular handle portion formed of sheet metal. This handle portion is provided along one side thereof with a guard member 19, the form of which is illustrated in section in Figure 4.

i From an inspection of Figure 4, it will be seen that the guard member comprises a rolled upper portion 20, and a straight depending portion 21 having a small bead 22 formed upon the lower end thereof. This guard member 19 may be formed integrally with the handle portion 18 or may be formed separately and secured thereto by any suitable means such as welding, soldering, or by rivets or screws.

Within the tubular handle 18, there is a spreader member 24 secured to the bottom portion of the handle by means of the screws 25. Referring to Figure 3, it will be observed that this spreader member 24 comprises a straight shank or securing portion 27 provided with screw threaded apertures for the screws 25, and an upturned, wedge shaped, portion 28 which projects upwardly into the tubular handle portion and is designed to pass between the

flange portions

14 and 15 of thevbinding strip 12 to separate these flange portions as particularly illustrated in Figure 4.

From an inspection of Figure 2, it will be observed that forwardly of the inner edge of the upturned portion 28 of the member 24, the bottom portion of the tubular handle member 18 is cut away leaving a pair of spaced

side members

30 and 31 in the forward end of which a roller member 33 is mounted upon a shaft 34 which projects through suitable apertures in the

side members

30 and 31. Beyond the apertures the

side members

30 and 31 are bent backwardly upon themselves and are then flared out so 7 that the side member 30 forms a fingerrest 35 and the side member 31 forms a thumb rest 36. The backwardly bent portions of the

side members

30 and 31 also serve to retain the shaft 34 in the apertures provided for it in the side members.

Washer members

38 and 39 are placed between the ends of the roller and the

side members

30 and 31.

From a further inspection of Figure 2, it

will also be observed that the end of the tubular handle portion 18 opposite the roller 33 is flared out at 40 and that the portion of the handle member surrounding the spreader 24 is bulged out at 41 to allow a sufiicient opening in the top of the handle member to start the binding strip over the spreader 24 and under the roller 33.

The. operation of the device is as follows:

. The rubber binding strip 12 is threaded through the tubular handle 18 as illustrated panel as illustrated in Figure 1. The tool is then drawn around the edge of the panel, the spreader 24 separating the

flanges

14 and 15 so that they pass easily over the edges of the glass and the roller 33 forcing the binding strip firmly down upon the panel.

After a certain amount of the strip has been applied to the panel, the tool is moved away from the panel and the operator grasps the binding strip immediately in front of the tool with his right. hand, at the same time holding the opposite end of the strip upon the panel with his left hand, and stretches the binding strip upon the panel. binding strip has been applied entirely around the panel, the over-lapping end of the strip is cut off and the two ends of the strip are forced flush together. A metal staple is then driven through the strip straddling the at 46, and by means of the screws 47 a stapling device generally indicated by the numeral 48. Referring particularly to Figure 7, the strip cutting device comprises a bracket 50 having secured to one edge thereof a slide 51, and a stem 52 having at the upper end thereof a knob 53 is mounted upon the slide 51 and carries at the lower end thereof a clamp 54 in which is secured the upper portion of a knife blade 55. The stem 52 is urged upwardly by means of a compression spring, not illustrated, to normally retain the knifeblade 55 above the binding strip l2. Pressure on the knob 53 however,"'will force the stem 52 down upon the guide 51 and will force the knife blade 54 through the binding strip 12 When the Ill to cut the binding strip to the proper length.

The stapling device 48 is mounted upon the side of the tool and comprises a bracket member supporting a guide 61 which in turn supports a stem 62 upon which'is a'knob 63. Below the bracket 60 1s a staple magazine 65 which holds a clip of staples which are spring pres-zed upwardly for the stapling device. The stem 62 is normally urged away from the tool by means of a compressionv spring or other suitable device but pressure upon the knob 63 will force the stem 62 toward the tool and cause a staple to be inserted into the adjacent ends of the binding strip. As the specificstructure of a stapling device of this character is old and well known, it is believed that a further description is unnecessary for the purpose of this disclosure.

In the operation of the modified form of the device, the binding strip is applied to the pgnel as described above. When the strip has en applied entirely around the panel, the rear end portion of the tool is raised,-the knob 53 is depressed to cut off the raised up end of the binding strip. The two ends of the binding strip are then forced directly together and the knob 63 is depressed to secure the ends together by means of a metal sta 10.
